Casappa Type PLP & PLM Series Hydraulic Gear Pump & Motor | PLP10, PLP20, PLP30 | 9cc to 51cc

PLP & PLM Series High-Performance Hydraulic Gear Pumps & Motors

Product Overview: The Casappa Type PLP (Pump) and PLM (Motor) Series are global benchmarks for versatility and durability in the hydraulic power sector. Featuring a high-strength three-piece extruded aluminum alloy body, these units are specifically engineered for continuous high-pressure operation in the most demanding environments. This range covers the full displacement spectrum from the compact PLP10 and mainstream PLP20 (including .9, .11, .16, .19, .25) to the heavy-duty PLP30 (including .43, .51). Utilizing advanced automated axial gap compensation, the PL series maintains a volumetric efficiency above 95% throughout its service life, serving as the premier power source for excavators, street sweepers, and industrial power units.

Key Technical Advantages:

• Superior Pressure Resilience: Rated for continuous working pressures up to 25 MPa (250 Bar) with peak capabilities reaching 28 MPa. Robust bearing designs support exceptionally long service life under heavy loads.

• Peak Volumetric Efficiency: Equipped with floating bushing technology that adjusts clearances in real-time based on pressure, minimizing internal leakage and ensuring consistent performance even at high temperatures.

• Modular Multi-Stage Capability: Supports single units, tandem pumps, and motor configurations, covering an extensive displacement range from 1.07 cm³/rev to 91.1 cm³/rev.

• Ultra-Low Noise Operation: Precision-ground gear sets drastically reduce fluid pulsation and mechanical noise, meeting modern industrial environmental standards.

• Target Applications: Auxiliary circuits for construction equipment, agricultural machinery drives, fan drive motors for municipal vehicles, material handling gear, and industrial hydraulic stations.
