Pump Velocity

Pump Velocity

Pump Velocity

(OP)
I have pump of having max. power 1500w. how can i calculate the velocity get from this pump?

RE: Pump Velocity

easy, look at the name plate for brand, model etc and then contact the manufacturer / agent or search the internet.

RE: Pump Velocity

(OP)
The only visible text on name plate is its power.

RE: Pump Velocity

mrashidmk,

It is not possible to answer this question in part because "velocity" is not a pump term. I think you might mean flowrate, but this is dependent on the head (pressure) the pump generates. Power of the pump is proportional to flow x head. If you keep the power the same and double the head, the flow is half.

Therefore it is not possible to answer this question with two unknowns.

1500W is 1.5kW. This is a small pump. What type of pump (PD or centrifugal). If PD, work out the volume pumped per revolution and then work out how fast the pump is turning.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Pump Velocity

(OP)
THE PUMP I AM USING IS CENTRIFUGAL. AND THE PURPOSE OF THIS PUMP IS FLUSHING. SO I NED TO CALCULATE HOW MUCH TIME IT WILL TAKE TO FLUSH THE WHOLE PIPE.

RE: Pump Velocity

mrashidmk,

Two things - first, please don't post in CAPITALS. This is interpreted as SHOUTING. This is not allowed on this forum

second. Please read the post above. you are asking for flow rate. Without knowing what pressure or head the pump is producing when it is flowing you CANNOT calculate or estimate the flow rate. Measure the pressure or simply turn it on and time how long it takes to fill a known volume ( e.g. an oil drum).

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Pump Velocity

(OP)
Sorry for the capitals. and thanking you for the grat reply :)

RE: Pump Velocity

Take an empty bucket and time how long to fill with the pump, this will be you an idea of the flowrate.

RE: Pump Velocity

You should be able to pump 60-80 gpm at 50-60 feet of head with a 1500 watt pump.
