Product Overview
The Casappa PLP20.31,5D0-31S1-LGE/GD-N-EL FS (Part No. 0174440N) is a precision-engineered external gear pump from the Casappa PLP20 series, a globally recognized platform for reliable medium-pressure hydraulic power generation. This unit operates on the external gear principle, utilizing a pair of high-precision meshing gears rotating within a durable aluminum alloy casing to draw fluid from the inlet port and displace it to the outlet. With a nominal displacement of 31.5 cm³/rev, it delivers consistent volumetric flow for industrial circuits requiring stable actuation and continuous duty performance. The “EL” designation indicates an integrated solenoid-operated unloading/dump valve, allowing the pump to be switched to a low-pressure standby condition for energy savings and reduced heat generation. The “FS” suffix denotes a specific factory configuration, and the “GD” code identifies the mounting and porting interface. This pump is a direct-fit replacement for OEM installations and is widely used in mobile and stationary hydraulic systems.
