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).
