For mobile machinery commonly used in the construction, agriculture, mining and forestry industries to work efficiently and safely, maintaining strong connections to the various equipment attachments is paramount. There simply isn’t time for productivity or connectivity problems on a job site where every minute matters.
Hard working excavators, tunnel boring, mining, oil field and forestry equipment typically use a variety of tool attachments that allow them to perform a variety of tasks, all necessary to get the job done quickly and safely. Some of these attachments require multiple connections to the hydraulic lines, depending on their individual function, like digging, scraping, scooping, grabbing, lifting, cutting or other movements.
At the job site, equipment tool attachments might be changed out several times in the process it takes to complete a project. Having the ability to quickly and efficiently swap out attachments saves the machine operator time and effort while also minimizing downtime.
Non-spill couplings for equipment attachments are key in a diverse range of markets like construction, agriculture, forestry and mining. From skid steers and excavators to feller bunchers and loaders to drill rigs, non-spill couplings enhance performance and safety in an environmentally responsible way.Discovering the value of non-spill couplings
These industries are discovering that non-spill couplings reduce hydraulic system breakdowns caused by dirt and other contamination that’s common in harsh working environments.
Parker’s non-spill couplings virtually eliminate hydraulic fluid loss that can happen during disconnection, reduce the risk of contaminating ground and water and decrease exposure of equipment operators and maintenance personnel to potentially dangerous chemicals. These non-spill couplings also minimize the risk of introducing contaminants in the hydraulic fluid.
Our non-spill couplings utilize flush face valves as part of the technology to reduce leaks in demanding conditions in the construction, agriculture, mining and forestry markets where hydraulic lines are subjected to the stress of high-pressure impulses. With several non-spill coupling options, we also offer screw-to-connect couplings providing a secure connection that is resistant to loosening or disconnection caused by vibration.
Here is a summary of how our couplings benefit the various applications that rely on mobile equipment to get the job done efficiently and safely.Agriculture
We understand the needs of farmers to simplify installation and equipment service. Our coupling solutions enable farmers to improve efficiency, reduce operating costs, meet durability and safety needs and comply with industry regulations, so they can focus on their critical role in society.
Our quick connect couplings are designed with farmers in mind, providing solutions that are robust and performance-tested to keep up with the high degree of use needed on the farm.
With the widest selection of couplings on the market, we offer a wide range of quick couplings for almost every farming application. With extensive knowledge of the hydraulic and pneumatic needs of agricultural equipment and machines, Parker leads the globe in coupling technology and innovation.Forestry
We offer heavy duty quick couplings for all forestry applications, from heavy mobile equipment to small hand tools. These couplings allow the hydraulic lines between the equipment and the tool attachments to be quickly disconnected and reconnected without extensive downtime.
Our non-spill couplings can be used on feller-bunchers, forwarders and loaders equipment, including brush cutters, mulchers and log-splitters. Quick couplers for excavators and other heavy-duty equipment save time and improve efficiency by allowing operators to quickly and easily disconnect and reconnect hydraulic lines when switching out the tools or attachments.Construction
Our non-spill couplings work well for skid steer attachments and compact tractors’ diggers, buckets and backhoes used in construction. Quick connect couplers allow loaders to use multiple attachments on a job site and allow users easily switch between attachments.
Loader attachments can be used on wheel loaders, tool carriers, telehandlers, skid steer and compact track loaders, and backhoe loaders. Hydraulic couplings can be used from within the cab, adding a safety benefit.Mining
Whether it’s long haul, surface mining, or continuous mining (coal), controlling operating costs and maximizing performance and longevity under harsh conditions is an increasing challenge for the mining industry. Our quick couplings consistently deliver value and performance and increasingly flexible solutions for mining applications. No one knows surface or underground mining like our staff of innovative application and design engineers.
For equipment that works outside, specifying and installing non-spill couplings for equipment attachments is insurance against downtime and key in preventing the accidental introduction of toxic chemicals that can cause harm to the environment and cost a lot in cleanup time and money.Cost of spills and contamination
Hydraulic fluid spills and contamination are a top priority for all these markets. The introduction of toxic, flammable material to the ground and water can cause harm to wildlife, fish, plants and drinking water. Spills often result in restricted work activities while job sites’ cleanup is complete.
The cost of fines and penalties, manpower, fuel, special equipment and the removal and containment of contaminated materials adds up to millions of dollars for individual companies and billions of dollars around the world.
Parker engineers have developed a deep understanding of the value of non-spill couplings for equipment attachments and designed products that pay off big time in the fight to keep the environment clean, people safe and equipment in tip-top operating condition.
The risk of wear-and-tear harm to equipment is greatly increased when contamination enters hydraulic systems. Known as “ingressed contamination,” dirt and water can enter a hydraulic system when a hose is disconnected or fluid is filled. Dirt can cause wear of hydraulic pump impellers, shafts, pistons and cylinders. Water can cause corrosion, dilute and alter the hydraulic fluid itself and lead to friction that creates damaging heat resulting in equipment failure and even fire.
Pump repairs and replacement are costly and waste time on the job where equipment uptime translates into more productivity and thus profitability.Working hard in tough environments
Because they are employed in outdoor applications that present a wide range of conditions from weather and terrain to dust and water and extremes in heat and cold, workhorses such as skid steers, tractors, snow plows, backhoes and other equipment often require servicing in challenging situations.
Non-spill couplings for equipment attachments have proved to be invaluable. Our high-end products feature corrosion-resistant zinc-nickel plating on push-to-connect couplings that can be connected or disconnected with one hand. Attachment and detachment are quick and easy. No tools are required.
The locking mechanism and critical sealing areas are protected by flush-face valving. Non-spill couplings for equipment attachments’ connections between hoses, pumps and pistons remain cleaner. They are easily cleaned should debris accumulate.Slim design, heavy-duty durability
Non-spill couplings from Parker’s Quick Couplings Division feature a slim design and profiles with a 90-degree option that allows for connection in tight spaces. The 90-degree couplings eliminate the need for additional fittings and reduce the number of potential leak points. They also present great safety advantages for operators and maintenance personnel as they can be connected and disconnected within an arm’s reach and require no tools.

To measure reference values for condition-based maintenance on a die casting machine, Stefan Pinkert from Schwabenhydraulik is using The Parker Service Master CONNECT from SensoControl by Parker's High Pressure Connectors Europe Division for the first time.Does the new device convince the measurement technology expert in practice?
One way to prevent damage to machines is to take regular measurements, the results of which are compared with reference values. From the deviation of the measurement data, it is possible to infer the wear on the machine and make a forecast about the remaining service life of certain components. Ideally, these reference values are measured before wear has occurred, i.e. on the new machine. For this reason, Pinkert, managing director at maintenance provider Schwabenhydraulik, travels to the metal foundry Druko Metallguss in October 2020. The foundry had purchased a new die casting machine six months earlier. Pinkert's goal on this day is to measure comparative values for later adjustment. In particular, he is concerned with valve technology.
He explains, "We can take the same measurement again in a year, for example. From the difference in response, we can see what the machine condition is and whether a failure is possibly imminent." Such comparative values also help in the event of an unplanned shutdown, as they can provide clues as to which fault has occurred. Two employees of Parker accompany the managing director to the appointment: Rolf Streicher, application engineer and Jörg Simon, project manager for diagnostic measurement technology.
In their luggage, the three have a brand-new diagnostic measurement system that was launched in April 2020: the Parker Service Master CONNECT. "We already had the previous model and were also very satisfied with it," reports Pinkert. "However, we had the problem that there were certain limitations, for example in the recording capacity and the recording duration."
The service provider was in close contact with Parker and learned about the new version of the device early on. Pinkert is now using the model for the first time during the measurement in October.How does the measurement work?
Measurements that serve maintenance purposes are one of the cases in which the managing director or his colleagues are called to the site. Another is troubleshooting. In the maintenance strategy that Druko Metallguss and Schwabenhydraulik follow in this case, they connect numerous sensors to the diagnostic system. Points are checked where experience shows that failures can occur.
"With the help of Parker's device, you can easily derive ten different measured values," Pinkert notes. "In large machines, you have up to four proportional valves on the press-fit part, so you often have to connect up to 16 different measuring points." This requires a lot of preparation, he continues, "You connect different measuring points for an hour and a half. The measurement itself is then finished after about ten machine cycles." So in failure prevention, the preparation time turns out to be quite long and the measurement time rather short.
Things are usually somewhat different when damage is detected. In this case, the failure pattern already provides initial indications of the cause. In this case, it is often sufficient to connect four to six sensors and take a measurement. Alternatively, the service employee can run the machine for six or seven cycles and compare the measurement results with the known values of previous measurements. Depending on how a machine or plant operates, longer measurements also make sense, for example overnight.Measuring devices in maintenance
Pinkert lists what is important for a measuring device in such applications: "For me, it is important to have a recording rate of one millisecond and to be able to measure very many different measuring points. I then have to be able to store the whole thing in the device accordingly, and with a reasonable recording time, not just 60 seconds." With the new device, he can now display the complete machine cycle, even if it takes three or four minutes. "Now it is possible for us not only to measure the actual process of casting but also to repeatedly record the complete cycle," Pinkert emphasizes.
"For me, it is important to have a recording rate of one millisecond and to be able to measure very many different measuring points. I then have to be able to store the whole thing in the device accordingly, and with a reasonable recording time, not just 60 seconds."

In fact, the device can record and process up to 100 channels simultaneously, confirms Simon. "We not only measured pressures on the machine today, but also temperatures, currents, voltages and so on," he relates. The device can also read out third-party sensors and machine data, he adds. "In that respect, this is a nice little electronic all-rounder."Differences from the previous version
Parker has changed several aspects of the measuring device compared to the previous version. One of the new features is the modularity of the hardware and software: the older device had a single input module that was installed in the device at the factory and also calibrated. Today, a user can use different measurement modules, two at a time, as needed. It's also possible to buy individual modules and replace them yourself on site. "The measuring devices recognize the input modules independently. The user is free to decide what he needs, depending on the application," explains Simon. At the moment, there are three standard measurement modules:
In addition, individual measuring module variants are possible.
Operation has also been revised in the development of the new generation of devices: With a color seven-inch touch display, it now resembles that of a smartphone or tablet. Users can create so-called measurement templates for recurring measurements. Parker has also improved protection against moisture and dust, as Streicher explains:
"We have increased the protection class from IP64 to IP65." Simon adds, "In general, this device can withstand very strong shocks and vibrations. For safe operating comfort, we have added additional tactile buttons on the right, on the side." There is also a fold-out stand and carrying handles to simplify handling. In practice, the clear display of the measurement data pays off above all, explains Pinkert: "The graphic display has improved extremely. You can now simply zoom with two fingers, just like on a cell phone. Operation is now much more intuitive." In addition, he can now evaluate a great deal on the device itself, instead of having to transfer the data to a PC in advance. "So that you can see something in the target/actual comparison, it is important that the recording rate is in the millisecond range, because a nicely smoothed curve is of no use to anyone," he points out.Additional equipment for measurements
The measurement system is available from the manufacturer either individually or as a pre-assembled kit, including a basic set of accessories. Pinkert chose this kit for the previous version and had good experiences. His conclusion: "You can already get very far with it." Parker offers various products for a wide range of applications, for example cables in different lengths, hoses, mechanical components and various sensors, as well as an outdoor case with trolley function. "One measures volumetric flow, the other might need speed or just pressure, maybe chemical compatibility, because of the aggressiveness of the media. We are very, very broadly positioned there," enumerates Simon.Intuitive operation counts
"It is of course extremely pleasant to have a measuring device where you can evaluate voltages and pressures very easily combined with each other. That is relatively rare on the market," concludes Pinkert. This is exactly the case with the proportional valve, for example: "There is the setpoint value, the actual value; then you have an enable signal, and in addition, you may still need to measure the 24-volt supply voltage, but at the same time you also want to see how the pressures develop accordingly."
“It is of course extremely pleasant to have a measuring device with which you can evaluate voltages and pressures combined with one another very easily. This is relatively rare on the market.”
Stefan Pinkert, managing director at maintenance provider Schwabenhydraulik
However, another point is important to the managing director: that the device can also be operated by someone who does not have it in their hands every day. "Then, when the fault occurs, he takes the device, connects it - and has no problem with the operation. The original measurement files can be sent worldwide and interpreted by a specialist using standardized software." Simon adds, "The device has sensor recognition. This means that if you connect a Parker sensor, it immediately displays the current measured value without any additional parameterization effort."

Reliability and repeatability
When selecting valves in POCT instruments, reliability and repeatability are of utmost importance. For a valve to have repeatability, it needs a long-life cycle, high yield rates and a proven track record. When determining reliability in a valve, you must evaluate the design, quality of material, and manufacturing process, and controls of the product.
POCT instruments are designed to operate in non-laboratory conditions. This means that the instrument needs to be designed to function using the power available from a standard wall power outlet. Where multiple valves and other components can be demanding power simultaneously it is important that the total amount of power being consumed does not exceed the power rating of the wall outlet. Selecting valves designed to use less power is an important first step. Another way to reduce overall power is to use hit and hold circuits. Hit and hold circuits allow valves to be fully powered and remain in that state for a short time before voltage and current are reduced to lower levels, while still allowing the valve to remain energized. This procedure allows the valve to stay open with much less energy. This also allows the valve to generate much less heat and decreases the power draw. This type of circuit option in a valve reduces heat, increases cycle life and lowers energy consumption — an ideal solution for original equipment manufacturers (OEMs).
Materials used in valve construction are crucial for valves with critical leak requirements. The term wetted material is important to understand. The wetted material is defined as any surfaces and/or components that are (potentially) exposed to or in direct contact with the medium under pressure. A few more important things to know before selecting a valve are permeation rate, compatibility with certain fluids (specifically what your system uses), and potential out-gassing that can occur.
Finally, look for the availability of subsystems. A subsystem is a pre-assembled module that includes tubing, fittings, regulators, valves on a manifold, and other accessories.
The benefits of a subsystem include:
Take a closer look
Let's examine a simplified fluidic circuit used in a POCT system. In this case, we are looking at a molecular diagnostics system. Most POCT designs use pneumatic pumps to provide the energy to move liquids around in the cartridge. This means that compact high-efficiency pumps are critical to reducing overall instrument size.
How it works
Air is controlled precisely by an electronic pressure controller. This pressurized air is fed into a manifold that is a permeant part of the instrument. Valves mounted in or on the manifold then control when and where the flow of air is directed to move the sample and reagents through the cartridge. Several types of valves are typically employed with the critical requirement that they are miniaturized to reduce the size of the manifold and therefore the entire instrument.
Digital or on/off valves are the most common in either a cartridge valve format that is embedded in the manifold or surface mount designs that are mounted on top of the manifold. Cartridge valves can reduce the footprint of the manifold by allowing valves to be placed very close to each other. The drawback is they make the manifold thicker and more expensive. Surface mount valves have a larger footprint on the manifold but can be supported by a thinner manifold design which weighs less and takes less space. Proportional valves can be used where there is a need to vary the flow instead of just turning it on or off. In operation, the various valves open and close at the right times driving the sample and reagents through the various steps of lysis, nucleic acid purification, amplification, and detection.

When fitters are asked what the main cause of assembly errors is, around 70 out of 100 respondents spontaneously answer: "The small dimensions are over-assembled and the large ones are under-assembled". This is a clear indication that in the world of hydraulic technology, assembly is still done by feel. Sometimes there are serious consequences when it comes to connections. Leakage or breakage due to pipe construction, vibration or force can be the result. The resulting repair of leaks is time-consuming and cost-intensive. So why not limit the potential for errors during assembly from the outset?Overmounting protection with 24° DKO sealing cone fitting
Parker Hannifin's High Pressure Connectors Europe (HPCE) has addressed this problem and re-engineered its range of directionally adjustable fittings. The result is the new 24° DKO sealing cone fittings with over-mounting protection. Due to their special design, smaller tube sizes (06-15L) can be assembled with a higher torque using the Parker 24° sealing cone fitting. This is Parker's response to strong customer demand for standardization of torques and increased robustness in the assembly process. This standardization has a particularly positive effect on assembly results in flow assembly at large series manufacturers, in machine and machine tool construction, but also in the assembly of mobile applications. Within maintenance, too, the standardized torques simplify assembly and minimize the potential for errors. This is because assembly is still carried out according to feel and experience, and the assembly recommendations of the manufacturer are often not known or not sufficiently familiar to the assemblers.How exactly does overmount protection work?
With the new over-assembly protection, installers can now no longer incorrectly or over-assemble the sealing cone fitting, but rather maximally "on block". The new design ensures that even with excessive assembly torques, the cone of the fitting remains protected and does not deform. This means that over assembly protection is integrated into the system when the limits of the connection are reached. The fitter notices immediately that he is not getting anywhere when tightening the screw connection.Standardize torques and avoid incorrect assembly
Behind the over-assembly protection is a product improvement that is as small and simple as it is effective: In the design of the DKO sealing cone, sizes 06L-15L have been extended cylindrically at the front end by a "nose" and can thus support themselves against the 24° conical tube seat (stop) of the bolting connection in the event of excessive torques. In sizes 18L to 42L and 06S - 38S, this is already done by the overmounting protection on the "shoulder" of the DKO fitting. Externally, the extension of the sealing cone has no effect on the dimensions of the overall component. An EW that is screwed onto a straight spigot (G) continues to have the same dimensions. The product improvement is therefore not diluted for the user by forcing him to make design changes but can counteract the threat of leakage in the future.
Another major advantage is that the Parker HPCE assembly specifications do not change as a result of the re-engineering. These can therefore continue to be used unchanged. Since the tapered part of the DKO sealing cone, including its groove, has not been changed, the O-ring dimensions and the proven sealing properties also remain unchanged - so the user can only benefit from the new improvement.

Medical technology continues to evolve towards diagnosis and treatment equipment that is closer to the patient - wearable or in the home. Examples include point of care diagnostics, dialysis, compression therapy machines, and negative pressure wound therapy devices. Medical equipment manufacturers are responding to this trend by designing smaller, more portable, and quiet devices to improve the patient's experience and comfort. To ensure a competitive edge, OEM design engineers are faced with integrating components that meet design specifications without compromising functionality.
We will explore how design innovations in diaphragm pumps are helping OEM design engineers mitigate noise, improve performance, increase product life and reduce service costs.
One of the biggest challenges to pump longevity is the brushless DC motor that operates the pump mechanism. Most diaphragm pumps operate similarly: a motor shaft rotates a connecting rod assembly that drives a diaphragm up and down to create a pressure differential that results in flow. This connecting rod and diaphragm are attached perpendicular to the motor shaft creating a reciprocating radial load. In other words, the load of the diaphragm is pushing and pulling on the motor shaft with every stroke. As you can imagine, doing this 3000 times every minute for thousands of hours can be tough on a motor and lead to increased noise and reduced life.The solution
Parker has a patented process to restrict the free movement of the motor ball-bearing balls so they roll in a fixed position and cannot chatter. This greatly reduces the noise, but more importantly, it allows the pumps to operate for thousands of hours at peak performance.
A winning combination
Parker has been building miniature diaphragm pumps for more than 20 years. Brushless motors are designed and built in the same ISO 13485 certified factory as the pumps. This combination delivers the best motor solution for customers, ensuring a reliable, long-life pump. Manufacturing the pumps and motors in the same facility also allows for strict control of the design, resulting in better quality control and change management.
The BTX pump
Parker’s BTX pump product line combines best-in-class diaphragm pump design, innovative brushless motor technology, ultra-low vibration, and advanced manufacturing techniques to bring a next-generation solution to next-generation device needs. The BTX Pump delivers high performance with superior quality and reliability. The product line offers a growing range of options for motor type, motor controls, and pump performance flexibility to serve a wide range of needs.
