Hydraulic Gear Pumps

GRH provides a variety of different displacements for hydraulic gear pumps, ranging from 0.16cc to 200cc and made of different materials, including aluminum, copper, and cast-iron.

According to different applications, GRH hydraulic gear pumps cover a wide range: low noise geared pump, ultrahigh pressure pump, Carter series shaped gear pump, chopping machine pump, PTO pump, spiral geared pump, bidirectional geared pump, and multi-stage geared pump. The maximum pressure reaches up to 30MPa.

An internal structure design means a higher volumetric efficiency, self-suction performance, sealing property and longer service life. Precise part manufacturing guarantees a higher mechanical efficiency and a rigorous process control ensures reliable product quality.

Features Compact and simple structure, convenient processing, small size, light weight, and cheap. Strong self-suction, no-sensitivity to oil pollution, wide speed range and impact resistance. Easy to maintain, reliable operation. Custom range Speed range: 500 r/min - 3500n/min Working pressure: < 300bar Displacement: 0.16 cc/r-90cc/r Based on above parameters, GRH offers the following standard ports:
