     Casappa manufactures a line of high performance gear pumps and motors for Mobile hydraulic systems. The gear pumps are the quietest in the industry. They are available with a wide range of built in valves, including relief, crossover relief, solenoid unloading and check. compliciteo


Aluminium body hydraulic gear pumps and motors

Gear pumps and motors built in three pieces with an extruded body in high resistance aluminium alloy. The wide choice of shafts, flanges and ports, in compliance with all international standards (SAE, DIN and EUROPEAN) allow for their use in an infinite variety of applications. Displacements from 0.07 in³/rev (1,07 cm³/rev) to 5.56 in³/rev (91,10 cm³/rev) available in groups 10, 20 and 30 Max. peak pressure up to 4350 psi (300 bar) Max. speed up to 4000 min-1

Cast iron body hydraulic gear pumps and motors

Gear pumps and motors built in three pieces with cast iron body. The new gear pumps and motors "PH" series is an evolution of the "POLARIS" series. "POLARIS PH" has a new body made of cast iron to have higher operating parameters and keep the full POLARIS versatility regarding shafts, flanges, ports and built-in valves. This project is targeted for forklifts, skid steer loaders and all those applications where traditional aluminium pumps are being pushed close to their limits. The possibility to mate the body with the cast iron covers further reduces noise levels, in addition to increasing strength. Displacements from 1.16 in³/rev (19,09 cm³/rev) to 2.01 in³/rev (33,03 cm³/rev) Max. peak pressure up to 4350 psi (300 bar) Max. speed up to 3500 min¹
  • High working pressure also for high displacements
  • Long service life
  • Low noise level
  • High volumetric efficiency also at high temperature
  • Inlet & Outlet optimization – High speed
  • Combination in multiple pumps
  • Built-in Valves simplify circuit design

Built-in valves for hydraulic gear pumps and motors

Anti-cavitation valves, maximum pressure relief valves, priority valves and “load sensing” priority valves built in the following series of gear pumps and motors: POLARIS, WHISPER, KAPPA, New KAPPA Compact
  • Reduced overall dimensions
