Application:
KCB marine pumps mainly used to lubricate the machinery as a lube pumps usually be used on the oil tank ship to transfer the oils, so they are called marine pumps, the pumps can be used on the ship to lubricate the power transmitting system, the pumps can transfer food grade media because of the stainless steel is used to be gears, the pumps can transfer low corrosive media because the stainless steel have corrosive resistance properties.
The pumps working conditions
The viscosity is 5×10-6～1.5×10-3m2/s (5-1500cSt)
The temperature is 300℃
Displacement is 1.1m3/h-600m3/h
Pressure is 0.28MPa--2.5MPa
We offer copper parts for transferring low temperature media
