Product Overview
The CASAPPA PLP20.25D0-31S1-LGE/GD-N-EL FS (Part Number: 0174439N) is a high-performance external gear pump from the renowned Casappa PLP20 series, engineered for demanding industrial and mobile hydraulic systems. This fixed-displacement pump operates on the proven external gear principle, utilizing precision-ground gear teeth that mesh within a durable casing to trap and displace hydraulic fluid with exceptional volumetric efficiency. The PLP20 series is widely recognized for its compact design, low noise operation, and robust construction, making it a preferred choice for continuous-duty applications requiring reliable flow delivery and consistent pressure performance. The model designation “25” indicates a nominal displacement of approximately 25 cm³/rev, positioning this unit as a medium-displacement pump suitable for a broad range of hydraulic circuits. The “D0” configuration denotes a standard drive shaft and flange arrangement, while the “31S1” suffix specifies the port and mounting configuration. The “LGE/GD-N-EL” designation indicates the specific rotation, sealing, and connection options, and the “FS” suffix confirms compliance with specific OEM or application requirements. This pump is a direct-fit replacement for OEM installations and is supplied under Casappa part number 0174439N.
