For increased simplicity, reliability and energy savings from your wheel loader, consider the proven results of split pump Intelligent Flow Control (IFC) architecture.
Typical Wheel Loader Architecture
For the most part, wheel loaders are currently employing a system featuring load-sensing technology, the main functions being steering and implement control. This system can utilize a single pump for both functions or two pumps. While this architecture has been practical, it can now be surpassed.
The Parker Global Mobile Systems team created an innovative concept that reduces system complexity while increasing efficiency and performance. The system uses two electric displacement controlled pumps and an electronically controlled open center valve with three sections. Now, each function can use full flow from both pumps during a single function operation, and a dedicated pump during multi-function operations for optimal energy balance.
IFC Value Analysis
In tests, the split pump IFC system used 24% less hydraulic energy compared to the baseline load-sensing system. In fuel consumption, this translates to fuel savings of 1.8 gallons per day, which could save $900 yearly per vehicle.Advantages Over a Traditional Load-Sensing System
Simplified architecture – using open center valves with an electronic displacement control pump reduces failure points, leak paths and cost.
Reduced energy losses – by controlling flow to specific functions, losses through the valve are minimized.
Improved response time – by using an electric control pump, the time from operator input to pump stroking is reduced.
Control Flexibility – with IFC, the exact amount of flow required can be controlled.
Parker is a global leader in motion and control technologies and the creator of split pump Intelligent Flow Control (IFC) architecture.
