Hydraulic Gear Pump, CBK Series

Hydraulic Pump, Hydraulic Parts for Tractor, Hydraulic Pump for Loader, Hydraulic Pump for Caterpillar

CBK series high-pressure gear pump is a vital part in hydraulic system. It adopts DU bearings with high loading capacity and aluminum alloy housings of high strength. The pumps are distinguished for high working pressure, wide speed range, various displacement choices, small volume, light weight, reliable performance and convenient maintenance, etc.

Apart from single and double pumps, CBK series can also be used by combining 3 or 4 pumps together in parallel, or connecting with other pumps in serial. Safety valve is optional.

Applications: main pump or auxiliary pump for a variety of engineering machineries

Advantages
1. Supported by high strength aluminum alloy casting body, whole bushing, and DU bearing, CBK series hydraulic pump features small volume, light weight, and various connection forms.
2. The pump is designed with whole bushing and made from casting, featuring high reliability, high pressure, high volumetric efficiency (94%) and beautiful appearance. It can be concatenated after other pumps.
