Product Description

Product Description

·GHD1 Series Pumps with external gearing for its massive cast iron construction are designed for the toughest operations in agricultural and construction equipment. The series covers a wide range displacement from 17 to 71 cm3.
·These pumps are characterized by a three-part, all-cast-iron structure: flange - body - cover. Bushings supporting gear studs are pressed into the flange and the cover. Gear wheels, which are optimised to achieve a low noise level, are made of ultra high strength steel. Liquid inlet and outlet are located in the cover from sides or axially in the cover. The axial power balancing is performed using sliding aluminium alloy pressure plates in which a shape sealing of balancing surface is located in grooves. The flange dimensions enable a design with a pre-shaft with bearings for a higher radial or axial load of the drive.
