Parker Electronic High Pressure Mobile Pump - Series eP2/eP3 is a variable, swashplate piston pumps with electronic controlled displacement control used for mobile applications. With a working pressure up to 350 bar, they are perfect for demanding uses such as forestry and construction equipment. The series includes both standard and supercharged versions. This ensures optimal performance even at high altitudes. The design also reduces operational noise by minimizing flow ripple, resulting in quieter operation.

These pumps come with advanced electronic displacement controls. Control options include pressure limitation, torque control, and speed compensation. Electronic displacement feedback provides precise flow control. It adjusts the swash angle in response to input commands. The closed-loop control system improves response times and enhances stability. This setup also increases fuel efficiency. Optional electronic pressure sensors support condition-based monitoring, which is beneficial for maintenance.

Parker eP2/eP3 Series is developed in a compact design, which makes them easier to install in limited space conditions. Ideal in Reachstackers, Heavy Lift Trucks, (All Terrain) Mobile Cranes, Cargo Loaders and other applications. These pumps comes with software controller enable real time adaption of controller characteristic to current machine function. Furthermore, the PCM ensures a smooth implementation and a high-performance usage of the pump.
