Product Overview
The CASAPPA PLP20.13,5D0-03S1 is a precision-engineered external gear pump from the Casappa PLP20 series, a globally recognized family of cast iron hydraulic gear pumps designed for medium-pressure industrial and mobile hydraulic systems. The PLP20 series operates on the proven external gear principle, in which two precisely meshed gears rotate within a durable cast iron casing, trapping and displacing hydraulic fluid to generate smooth, continuous flow. With a nominal displacement of 13.5 cm³/rev, this model delivers reliable volumetric performance for demanding circuits requiring consistent flow delivery, high mechanical efficiency, and long service life. The PLP20 platform is widely specified as a drop-in replacement for OEM gear pump applications across industrial machinery and mobile equipment.
