Product Overview
The BEINLICH ZPD 3-37,40-KIS-L-FCV/R/GL-SP/009 is a high-performance external gear pump engineered by BEINLICH for demanding industrial hydraulic systems. Operating on the positive displacement principle, this pump utilizes a precision-meshed pair of external spur gears to draw hydraulic fluid from the reservoir and deliver it under pressure to the circuit. The ZPD series is recognized for its robust construction, high volumetric efficiency, and consistent flow delivery across a wide range of operating conditions. With a nominal displacement of approximately 37.40 cm³/rev, this model is well-suited for medium-to-high flow applications requiring reliable and continuous hydraulic power. The integrated valve and control features denoted by the model suffix (FCV/R/GL-SP) indicate a factory-configured unit with specific flow control, relief, and porting options tailored to the end application.
