Electric Motor To Run Hydraulic Pump

How do you calculate the hydraulic horsepower of a pump.

Electric motor to run hydraulic pump.

Simply take the gallons per minute gpm multiplied by the pump pressure psi then divide that number by the result of 1 714 times efficiency we used 85. Electric motor horsepower hp required to drive a given hydraulic pump use this equation to help figure out what electric motor horsepower hp is required to drive a hydraulic pump. Is this a reasonable idea. Hydraulic pump and motor must work as a team.

For optimum performance the pump and motor must be correctly matched. Identifying a right sized motor for your hydraulic pump does not always ensure you are using the most efficient motor. These types of electric motors also can be run indefinitely at their rated hp plus an additional percentage based on their service factor generally 1 15 to 1 25 at altitudes to 3 300 ft. The input horsepower required for a pump that needs to.

To find the input horsepower requirement for a hydraulic pump use this hydraulic pump horsepower formula. Gas powered hydraulic pump double acting 5 5 hp motor 2 gpm 3200 psi. 3hp hydraulic power unit 10 gal 208 230 460v pump a10vso 18 dr 31r pkc62n00. Flow gallons per minute.

I am considering replacing a 15hp 720rpm electric motor which drives a lift pump which will run continuously. Pressure pounds per square inch. I will use a tractor hydraulic pump to provide 15gpm at 1500. The horsepower required by a a pump with flow 20 gpm and 1500 psi increase in pressure can be calculated as p hp 20 gpm 1500 psi 1714 17 5 hp.

An electric motor is relatively easy to select because at any given horsepower there are only a few fixed speeds from which to choose and it does not have to be matched to the alternator which supplies the power. Example hydraulic pump. Electric hydraulic pump 2 stage solenoid valve double acting 10000 psi 7l cap. Note that the equation above is for a pump with 100 efficiency which in the practial life is never true.

The service factors on most open frame sizes is 0 15 which means that the motor can be overloaded about 15 above current shown on its nameplate assuming it is being operated in a normal temperature environment. Could you recommend a motor which might fit this application. Hp flow x pressure 1714. Here is the 6 quick ste.

3 shows a temporary large torque excess that can provide additional muscle to drive the hydraulic pump through momentary load increases. The motor most often used to drive a hydraulic pump is a 3 phase induction type design b motor.
