eP2 - NEW ELECTRONIC CONTROL A NEW STANDARD IN PRODUCTIVITY
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.
The availability of both a standard (P2) and a supercharged, internally boosted
version (P3) allows for high flow operation at the most diverse inlet
conditions. 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.
After having proven in load-sensing
systems for many years the product line is now extended by a NEW ELECTRONIC
CONTROL CONCEPT, setting new standards in RESPONSIVENESS, STABILITY and -
foremost - EFFICIENCY. By banishing the losses of standard hydro-mechanical
controls eP2 provides for an increased volumetric efficiency. On top of that
eP2 paves the way for new hydraulic system approaches such as the purely
electronic control of single actor operation, which eliminates the delta p
losses of a conventional LS system.
Featuring an electronic displacement
feedback the new design can take advantage of a closed control loop, ensuring
highest accuracy and repeatability at any time. Beside the standard electronic
displacement control function which can easily be integrated into existing
system control logics eP2’s hardware also grants for electronic pressure
limitation, torque control and speed compensation.
In addition to the pump itself
Parker also introduces a new pump control module providing the logic as well as
monitoring options for the whole range of electronic control functions. As a
matter of course all components have been CE certified.
eP2075 will be launched to serial
production by July 2017, followed by all further displacements of P2 as well as
P3 within the coming months.
