Casappa PLM PLP Gear Pump Motor

Casappa PLM PLP Series – High-Efficiency Aluminum Gear Pumps & Motors

The Casappa PLM PLP Series, also known as the Polaris line, represents a benchmark in external gear pump and motor technology. Built with a body made of high-resistance extruded aluminum alloy and heavy-duty covers, these components offer an excellent power-to-weight ratio without compromising on strength. The series is engineered with hydrostatically compensated thrust plates that ensure high volumetric efficiency and reduced internal friction.

Whether configured as a PLP gear pump or a PLM gear motor, this series is highly adaptable. It supports a vast array of standard flanges (SAE, DIN, European), shafts, and porting options, allowing for seamless integration into diverse hydraulic circuits. The modular design also facilitates the creation of multiple pump stages with common or separate inlets.

Key Features & Benefits

• High-Resistance Aluminum Body: The extruded aluminum housing provides superior thermal dissipation and lightweight performance while maintaining structural integrity under high pressure.

• Modular Three-Piece Design: Allows for flexible configuration and easy maintenance, supporting multiple pump combinations for complex circuit needs.

• High Efficiency: Features advanced axial compensation and precise gear geometry to minimize internal leakage and noise, even at high speeds.

• Wide Operating Range: Capable of handling peak pressures up to 300 bar (4,350 psi) and speeds up to 4,000 RPM, making it suitable for demanding cycles.

• Versatile Options: Available with integrated outboard bearings for heavy radial loads and various built-in valve options (relief, anti-cavitation, priority).
