Parker Aerospace’s Fluid System Division has a long history of supplying fuel pumps to both the civilian and military aviation markets. Detailed analysis and testing, combined with extensive hours of field operational experience, ensure our off-the-shelf pumps provide a proven, low-risk, and cost-effective solution for aircraft fuel system design.
Whether a fuel system requires a boost or transfer pump, each design within Parker’s product-line family has unique features and can be fully customized to meet specific operational requirements for fuel type, delivered flow, inlet/discharge pressures, and temperatures (fluid and ambient). Variations in mounting configuration, available electric drive power, and allowable installation weight can be accommodated to provide a fully customized solution if an existing design is not satisfactory for any new or retrofit applications. All pump models are designed to the requirements of MIL-STD-704, MIL-STD-810, ARP-5794, and RTCA DO160.
Parker Aerospace fuel pumps typically perform two functions within the fuel system. A “boost pump” supplies pressurized fuel from the main supply tank directly to the engine. A “transfer pump” moves fuel from one tank to another to maintain the center of gravity of the aircraft and to ensure the primary tanks remain full during flight. Pump selection is based on the requirements for delivered flow and pressure, as well as the available electric power system of the aircraft. To supply the optimal off-the-shelf solution, any specifications associated with a new application should be sent to Parker so the best available option can be selected and presented to the customer.
Designed for general aviation, business jet, and rotor aircraft, these brushed pumps run on a 28 VDC power system and perform both the boost and transfer functions in the fuel system. The direct-drive motor features carbon brushes that power a wound armature shaft. Hydraulic elements include centrifugal and vane assemblies. Pump mounting arrangements are tank submerged (wall and floor), in-line (outside the fuel tank), and cartridge/canister (wall and floor mounted with the pumping element removable without draining fuel from the tank).
Designed for civilian and military aircraft, these brushless pumps run on a 28 VDC power system and perform both the boost and transfer functions in the fuel system. The pump is powered by a brushless DC drive system that consists of a permanent magnet motor and an analog electronic controller. Hydraulic elements are centrifugal assemblies. Pump mounting arrangements are tank submerged (floor), and cartridge/canister (floor mounted with pumping element removable without draining fuel from the tank).
Designed for military aircraft, these brushless pumps run on a 270 VDC power system and perform both the boost and transfer functions in the fuel system. The pump is powered by a brushless DC drive system that consists of a permanent magnet motor and a digital electronic controller that runs on configuration-controlled software. Hydraulic elements are centrifugal assemblies. Pump mounting arrangements are tank side-wall (bracket) mounted.
Designed for regional jets, rotor aircraft, and military aircraft, these pumps run on a 200VAC (L-L), 400 Hz constant frequency power input and perform both the boost and transfer functions in the fuel system. The electric drive is a classical induction motor with a copper-wound stator and squirrel-cage rotor. Hydraulic elements include centrifugal and gear assemblies. Pump mounting arrangements are tank submerged (wall and floor), in-line (outside the fuel tank), and cartridge/canister (wall and floor mounted with the pumping element removable without draining fuel from the tank).
Designed for small and large commercial transport aircraft, regional jet, and military aircraft, these small frame and large frame pumps run on a 200VAC (L-L) and 400 VAC (L-L), variable frequency power input (360 to 800 Hz) and perform both the boost and transfer functions in the fuel system. The electric drive is a classical induction motor with a copper-wound stator and squirrel-cage rotor. Hydraulic elements include centrifugal assemblies. Pump mounting arrangements are tank submerged (floor), and cartridge/canister (wall and floor mounted with pumping element removable without draining fuel from the tank).

Chvalis is an expert on delivering turnkey solutions according to rail manufacturer's specifications, including delivery, installation and commissioning. Chvalis has been using Parker's products since 1992 in its systems for their unmatched quality, reliability and security. Components also meet the most demanding certifications. In the railway industry, Chvalis is the holder of the Certification of Technical Competence of the Czech Railways supplier and the SŽDC Supplier's Certificate.
Thanks to its extensive network of local branches, which are always associated with the ParkerStore service and ParkerStore sales hydraulics and tires, Chvalis is able to provide rolling stock operators 24-hour warranty and post-warranty service. The ParkerStore retail locations are fully equipped for the production of hydraulic hoses and are certified by the "ParkerStore Hose Certification Workshop."
Until 2013, Chvalis supplied hydraulic systems only for auxiliary drives, such as compressor drives for compressed air production; the drive for the combustion engine cooling fans and the electric alternator drive for the production of electric motors. In 2013, the company received a call for a comprehensive design and solution for the supply of a complete hydraulic traction drive, including auxiliary drives for 35 units of MUV series 74.02 001-035 series, for CZ LOKO, the manufacturer and supplier of Czech Railways - SŽDC.
Chvalis has developed a technical solution for its own drive - an unconventional way of using its own innovative, open-circuit hydraulic system instead of competing with a preferred closed circuit. The system, while technically more demanding, precisely and comfortably addresses all the requirements of all traction control conditions controlled by the parent electronic control system of the vehicle. In addition, the circuit allows for hydraulic braking, which was used for the cruise control system. This makes the work of the drivers more efficient and saves the cost of the vehicle operators, reducing the wear of the brake discs of the standard pneumatic braking system of the vehicle. The standard brake is used most of the operating time, using this circuit for braking, until the vehicle stops.
Hydraulic circuits are built using the Parker product portfolio, including Ermeto E02 pipe systems and hose systems from certified hoses for rolling stock. These hydraulic circuits, mainly PV-plus piston control pumps in conjunction with the F11, F12, F1, F2, and F14 hydraulic motors of the V14 series, deliver a minimum fault, provide high reliability and long service life.
Thanks to previous experience with the 35-piece MUV74.02 series, Chvalis was asked by CZ LOKO's customer for the design and delivery of a complete hydraulic traction drive and auxiliary drives for a new series of 50 MUV 75.00 Universal Motor Vehicles. This new unit had the requirement to maintain the same hydraulic traction drive that has proven itself in the past series. In addition, the requirement to increase the hydraulic proportional brake power and increase the number of auxiliary hydraulic circuit circuits has been accepted: hydraulic hand, grass mower, hydraulically independent trolley tipping system, and suspension lock.
After the demanding testing of the first prototype in December 2017, the production of a 50-piece series of cars was launched in January 2018, again using the innovative Chvalis hydraulic system with proven hydraulic components from Parker.

Sealing can often be a frustrating challenge when dealing with flow batteries. Determining what materials are compatible with certain chemistries or developing a profile that provides optimal sealing under available compression can be a time-consuming task for those outside the sealing industry. A trial and error approach can have a significant overall cost impact through multiple prototype iterations, prolonged testing, and ultimately, delaying product commercialization.
Parker’s design and material engineers can provide support to your team in the critical, early stages of product development. With hundreds of engineered elastomeric materials to choose from, our team can identify and recommend a compound that works with your specific electrolytes or other fluids. With the exceptionally long lifetime requirements of flow batteries, our homogeneous rubber provides the elasticity needed to handle the many charge-discharge cycles the battery will see in its life.
Our engineers can significantly reduce design time by utilizing finite element analysis early in the process. FEA is a sophisticated computer modeling program that demonstrates a visual simulation of how materials for a proposed seal design might perform in the application. Material performance over a range of conditions is tested to see if the product will perform as expected. FEA can be repeated as many times as needed to fine-tune the design and make the final product as robust, functional, and reliable as possible. This process can be performed before prototyping, mold design or production is undertaken, greatly reducing the possibility of errors or redesign issues occurring later.
With continuous advancements materializing in the energy storage market, we fully understand the urgency of moving a product from development to commercialization. Parker can provide your team with resources to improve both the quality and speed of seal design in the critical prototyping stage, reducing overall cost.
After commercialization, Parker’s O-Ring & Engineered Seals Division can support your high volume production utilizing one of our 14 manufacturing locations dedicated to molding and extruding elastomeric products. To ensure the highest levels of material quality, state-of-the-art laboratories and testing equipment are housed in our two North American technology centers.

Over the last several years, the trend in the oil and gas market has been the near constant decrease in oil prices. As prices continue to drop, companies must find ways to remain profitable by streamlining costs. Design engineers are continually seeking more efficient technologies that can provide the same production capabilities while lowering the cost of operation.
Parker axial piston pumps provide a new-found efficiency. The P1 and PD Series Pumps are a step above the competition because of their energy recovery feature. This feature greatly reduces energy expenditure which saves cost. The pumps are designed to function as a pump to raise the rod string, then as the rod string gravity lowers, the pump is designed to go over center and work as a motor to recover the kinetic energy, which can then be used when raising the rod string or putting the energy back to the grid. In addition, this design allows the pumps to meet duty cycle requirements in applications where competitive products cannot accomplish this.
The P1 and PD series also have exceptional bearing life, which allows it to last longer than competitive product. This reduces down-time and the total cost of ownership. In an industry where down time is extremely costly and operating costs are critical, this feature is invaluable.
The P1 and PD medium pressure axial piston pumps utilize electronic control systems to optimize performance with the ability to work with their own ECU or directly with the machine or vehicle’s ECU. The pumps ECU even feature a CANbus interface to support whole-vehicle CANbus systems.
Besides electronic controls, the P1 and PD series offer a broad range of controls, including load sensing capabilities. In oil and gas applications where there can be wide fluctuations in flow and pressure, load sensing controls can save considerable amounts of input power. A load-sensing controlled variable pump eliminates most inefficiencies created by fixed displacement pumps. This reduces the amount of energy lost when the pump is not operating at maximum flow and electronic controls just take that one step further minimizing losses even more than a load sense control.
As the public continues to demand a lower dependence on foreign sources of oil, companies are hastily trying to find domestic reserves in commercial quantities. This has forced companies to look for and produce oil and natural gas in locations previously thought to be too close to residential and commercial areas, greatly increasing the need for low-noise equipment due to regulations of operating in such areas.
The unique design of the P1 and PD allow them to excel in low-noise applications. They provide exceptional motor function, while leading the competition in noise reduction. They provide such low noise output that they can be used in a wide array of new low noise applications that have never been tapped due to limitations of other products, while still being cost competitive and highly efficient.
P1 and PD Piston Pumps are now available for purchase on parker.com. Simply add products to your cart for shipment from a Parker Distributor.

Whether you're looking for electrical power-trains and components, battery management systems, thermal cooling materials or EMI shielding solutions, you’ll find it at all #EVT.
And this year didn’t disappoint – Parker Chomerics, in its second year of exhibiting, prominently featured a prototype urethane-based, 3.0 W/m-K dispensed thermal interface material (TIM) designed for high volume, EV battery applications requiring reliable thermal cooling performance. With an in-booth dispensing machine provided by PVA, show attendees were introduced to a different technology alternative than silicone dispensed TIMs.
Also, featured at the Parker Chomerics booth was an electric vehicle battery simulation, portraying what the compressed urethane TIM might look like in application against the battery cells and the cooling plate of the battery container. Depending on the manufacturer and design, some battery cells are arranged into a container which could be the size of a queen mattress, so proper wet out and adherence is critical to proper thermal cooling.
Parker Chomerics was also a featured speaker during the Thermal Management: Materials, Packaging & Performance track on Thursday, September 13th. Matthew Finley, global marketing manager of Parker Chomerics, took the viewing audience through an expert presentation focused on the differences between silicone and urethane dispensed thermal interface materials for EV applications.
Other technologies featured at this year's show included a variety of fluid seals, Press-In-Place (PIP) seals, o-rings, and molded shapes. Parker's innovative solutions for gearing and power transfer, battery life and electric motors can withstand a variety of environments, fluids, pressures, and temperatures. Sealing solutions for batteries require low compression set, temperature resistance, fire resistance, media resistance, low closure force and must be adaptable to a wide range of geometries.
Our team members were proud to represent Parker Chomerics at EVT18 and garner the opportunity to network with other professionals, engage with current partners, and nurture relations with future partners. We hope to see you again next year!
