GHD Features

 

** QHD1 series are particularly designed to be used in mobile hydraulic systems of agricultural, heavy construction and road building machines as well as in advanced hydraulic systems of material handling devices. The QHD1 series covers the range of displacements from 10 to 100 cm3 /rev.
** The pumps are characterized by simple construction with hydraulic pressure balance, compact dimensions and a wide range of connection types. QHD1 pumps have a two-piece all-cast-iron construction. The basis consists of a supporting body with a blind chamber for gear wheels and a fastening flange. The body as well as the flange are made of a high-quality grey cast iron. In the body and the flange, sliding sleeves for gear wheels are molded. Gear wheels with 12 teeth made of ultra high-strength steel, which are optimised to achieve a low noise level. The axial pump balancing is performed using sliding aluminium alloy pressure plates in which a shape sealing of balancing surface is located in grooves. For heavy duty with a weight-bearing drive shaft, the pumps can be equipped with front-end roller bearings. QHD1 construction enables the pumps to be used already at low revolutions at high pre-nssure.
** QHD1 pumps are produced in various designs of divers clamping flanges as well as liquid inlets and outlets. These
pumps comply with the standards ISO, SAE, UNI and other world-recognised standards and can be delivered in
simple or multiple designs. They can also be delivered in a reversible design, with external or internal drainage..
