New Electronic Control Concept

After having proven in load-sensing systems for many years Parker’s series P2/P3 is now extended by a new electronic control concept, setting new standards in RESPONSIVENESS, STABILITY and EFFICIENCY. Beside the standard electronic displacement control function which can easily be integrated into existing system control logics eP2/eP3’s hardware also grants for electronic pressure limitation, torque control and speed compensation.

The New Standard in Productivity


Fuel Savings

Compared to a conventional hydro-mechanical compensator based approach the electronic displacement control of eP2/eP3 is characterized by a significantly reduced compensator oil consumption. Thus eP2/eP3 provides for considerable power savings of up to 1 kW*.

The control design of eP2/eP3 also enables new hydraulic system approaches such as the purely electronic control of single actuator operation, which eliminates the delta p losses of a conventional LS system.

Outstanding Performance and Productivity

Featuring an electronic displacement feedback the new design takes advantage of a closed control loop, which provides for increased accuracy and system response as well as minimized oscillation.

At the same time eP2/eP3’s swash angle sensor provides for CONDITION MONITORING OPPORTUNITIES, granting for improved sub-system communication and increased machine availability. 

Optimized for heavy duty mobile applications

Parker’s P2/P3 series has been designed to meet the specific demands of heavy duty mobile applications. By featuring an optimized envelope and a unique port layout the product line provides for a cost saving DIRECT MOUNT on most typical mobile transmissions. High speed ratings enable high flow and productivity levels. With continuous pressure ratings of up to 350 bar P2/P3 provides a high power density and enables DOWNSIZING of mobile machinery. As a standard every P2/P3 comes with an integrated pre-compression volume which ensures low ripple operation and REDUCED NOISE EMISSIONS.
