Gear hydraulic motor POLARIS PH series

variable-displacementcast iron

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 0.50 in³/rev (8,26 cm³/rev) to 2.01 in³/rev (33,03 cm³/rev). 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 Anti-cavitation valves Maximum pressure relief valves Priority valves “Load sensing” priority valves By-pass electric valves Proportional relief valves Reverse valves
