GHP Series Pump

Pumps with Flange and Cover in Cast Iron, 1,4 – 87 cm³/rev Displacement.

These range of products have a new series of pumps named GHP, where groups named GHP1, GHP2, and GHP3 are suitable for the most different application in both industrial and mobile sectors. Available in different configurations (European, SAE, German standard) in a single rotation or reversible version. Suitable for heavy-duty conditions.

Generally, these gear pumps usually consist of a gear pair supported by two aluminum bushes, a body, a securing flange and a cover. The shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal and the outer being a dust seal). An elastic securing ring secures the ring in place. The body of the pump is made of the special hi-resistant aluminum alloy obtained through an extrusion process, while flange and cover are made out of spheroidal cast iron; this in order to ensure minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure.

Special compensation zones onto bushings, insulated by special preformed seals with the anti-extrusion ring, allow fully free axial and radial movement to the bushes, which is proportional to pump operating pressure. In this way, internal dripping is dramatically reduced, thus ensuring very good pump performance (both in terms of volume and in general) and proper lubrication of pump moving parts.
