Pump Flowrate
Pump Flowrate
(OP)
Hi all,
got a bit of a problem with a pump.
Data:
liquid handled: hydraulic oil
discharge pressure: 70-80 kp/cm2g
suction pressure: 0-0.1 kp/cm2g
efficency: 75%
speed: 3550rpm
rotation: clockwise
seal type: mechanical
weight: 13kg
frequency: 60Hz
voltage: 440V
Viscosity @ 40degC is 32.5
viscosity @ 100degC is 6.4
is there anyways of calculating pump flowrate from this
thank you

PS: Is the pressure unit kg/sq.cm?
RE: Pump Flowrate
viscosity units are centistoke and the inlet and outlet pipe diameter is 80mm
thanks

If you had the power drawn by the motor you could combine this with the pump efficiency and head to calculate the flow, but you would have to get the efficiency off the curve and you might as well get the flow directly off the curve.
I am as confused as Quark about your pressure units. What is a kp? kg/cm2 is a common pressure unit, but kp/cm2 is one I have not come across.
