Marine Diesel Oil Transfer Gear Pump

● Series: KCB, 2CY
● Type: gear oil pump
● Capacity: 1.1~170m3/h
● Applicant: diesel oil, lub. oil

Description

KCB series gear pump is usually used on marine for diesel oil transfer pump, compared to 2CY series gear pump it containing safety back flow valve so it is upgrade type of 2CY series pump.

Application
KCB series gear pump applies to delivering non-corrosive lubricating-oil or equivalent liquid without solid particles and fibers at temperature below 80℃ and with the viscosity of 5×10-6～1.5×10-3m2/S(5-1500cSt).

Application Scope
It can give performance as transfer pump or booster pump in oil delivery system. It can be also applied as a fuel pump for delivery system, pressurization and injection in fuel supply system and in all industry fields as lubricating pump.

Structure Features
1.KCB series gear pumps are mainly composed of gears, axles pump body, pump cap, safety valve and axle-end seals etc. The heat treated gears have the advantage of higher hardness and intensity, and rotate with the axles inside the replaceable bearing sleeves. All of pump's parts can be lubricated by delivered medium when working.
2. The pump is properly designed with leakage and return chute, which lets the gears bear the least torque force and reduces load and wear on bearings bear the least torque force and reduces load and wear on bearings in order to raise pump's efficiency.
3. It is also designed with safety valve for protection against overload. The full return flow pressure of the safety valve is 1.5times higher than the rated exhaust pressure of the pump. It can be also adjusted within the allowance of exhaust pressure range according to circumstances .But please note the safety valve can't be applied as pressure-reducing valve for long time .You may install pressure-reducing valve separately on pipe-line if needed.
