POLARIS gear pumps and motors meet a wide range of mobile and industrial applications with SAE and EUROPEAN mounting flanges. The extruded aluminium body houses single piece gear, journal, shaft assemblies with a pressure balancing system that provides the highest volumetric and overall efficiencies available.

Exceptionally large bearings make possible the most complete range of drive shafts in spline, parallel keyed, and tapered versions to meet all SAE, DIN, and EUROPEAN standards. POLARIS 20 is available with optional one piece SAE B shaft and flange.

Wide range The many choices of shaft size and type, mounting flanges, ports and displacements make POLARIS easy to fit, or retrofit to virtually all applications. The largest displacements available in POLARIS 10, 20, 25 and 30 can make compact solutions possible where other manufacturers would generally offer a physically larger unit.

Specifically designed for either side or rear ports, POLARIS can be provided with common inlets on multi section units. Very large inlet ports ensure maximum flow and eliminate cavitation under tough operating conditions. All sizes of pumps and motors are available in both uni and bi-directional versions. Motors are suitable for either parallel or series operation.

Built in valves In addition to the design flexibility offered by multi-section units of different frame sizes and displacements from standard parts, circuits can be further simplified by using built-in valve options: priority, anti-cavitation, relief pressure control, load sensing, electric venting, etc. New combinations can easily be provided for OEM applications

Flow Dividers The POLARIS is particularly suitable for multi-section flow dividers which offer consistent flow division over the complete pressure/flow range. When assembled for multiple cylinder applications, they will automatically reset the end of stroke using relief and anti-cavitation valves. Now available in the new compact design with the inlet port on the rear cover.
