3.2.3 P3 pumps with drain port in the rear cover The main benefit of this version is a continuous cooling flow through the case. Thus a better volumetric efficiency is provided. Flow out of the drain port can be up to ~ 50 l/min and is depending on back pressure in the drain line as well as drive speed.

Start up Prior to start up, the pump case must be filled with hydraulic fluid (use case drain port). Initial start up should be at zero pressure with an open circuit to enable the pump to prime. Pressure should only be increased once the pump has been fully primed.
