Re: About motors

What type of pump? i.e. centrifugal or? Vertical, horizontal? How will it be coupled to the motor?or how will the motor be driving the pump? What will the pump be pumping, i.e. the environment? etc.

Re: About motors

the pump has a design curve --- gallons per minute vs rpm ---this is what will determine the h.p. and speed of the motor to drive it.....

Re: About motors

First you calculate the water horsepower required, and then get a motor thats bit larger to allow for the efficiency lost.
Its much easier to go to a pump manufacturer and have them size the pump and motor, typically you will spec out 600 gpm at 100 ft TDH, they will size the motor for you.
