Hydraulic Gear Pump, CBY Series

High Pressure Pump, Hydraulic Pump for Forklift, Hydraulic Pump for Truck, Hydraulic Pump for Hoist

CBY series hydraulic high-pressure gear pump works as a driving part in a hydraulic system. It is made up of high-strength ductile iron housing, DU bearings of large bearing capacity, and floating side panel. This kind of hydraulic pump is characterized by high pressure, various speed options, simple structure, reliable performance, and long service life. It can be used in serial.

Applications
Hydraulic pump for excavator, hydraulic pump for bulldozer, as well as other machineries and harsh construction environments

Advantages
CBY hydraulic gear pump shows excellent anti-fouling and low-speed performance (92%). It is of simple structure and can be applied in harsh environment.
