KCB Series Gear Pump
1. Uses
It applies to delivering non-corrosive lubricating oil or equivalent liquid without solid particles and fibres at temperatures below 300°C and with a viscosity of 5×10−6∼1.5×10−3m2/s (5-1500 cSt). By reducing the speed, the pump can deliver liquids with a viscosity up to 5×104cSt.
2. Application Scope
- It can serve as a transfer pump or booster pump in oil delivery systems.
- It can also be applied as a fuel pump for delivery, pressurization, and injection in fuel supply systems.
- It can be used in all industrial fields as a lubricating pump.
3. Structurer Features
KCB series gear pumps are mainly composed of gears, axles, pump body, pump cover, safety valve, and axle-end seals. The heater-side gear has the advantage of higher hardness and intensity and rotates with the axles inside the replaceable bearing sleeves. All of the pump’s parts can be lubricated by the delivered medium when working.
The pump is properly designed with leakage and return chutes, which let the gears bear the least torque force and reduce load and wear on bearings to raise the pump’s efficiency.
It is also designed with a safety valve for protection against overload. The full return flow pressure of the safety valve is 1.5 times higher than the rated exhaust pressure of the pump. It can be adjusted within the allowable exhaust pressure range according to circumstances, but note that the safety valve cannot be applied as a pressure-reducing valve for long-term use. You may install a pressure-reducing valve separately on the pipeline if needed.
The direction of rotation is clockwise when viewed from the coupling end.
