Electric Motor To Run Hydraulic Pump

Example hydraulic pump.

Electric motor to run hydraulic pump.

I am considering replacing a 15hp 720rpm electric motor which drives a lift pump which will run continuously. I will use a tractor hydraulic pump to provide 15gpm at 1500. How do you calculate the hydraulic horsepower of a pump. 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.

Pressure pounds per square inch. Here is the 6 quick ste. 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. Note that the equation above is for a pump with 100 efficiency which in the practial life is never true.

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. 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. Could you recommend a motor which might fit this application.

Gas powered hydraulic pump double acting 5 5 hp motor 2 gpm 3200 psi. 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. Be sure to read part 2 of this post to learn how rms loading and hp limiting can help you scale down the size of your electric motor to save money while maximizing efficiency.

For optimum performance the pump and motor must be correctly matched. 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. Flow gallons per minute. 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.

Hydraulic pump and motor must work as a team. Electric hydraulic pump 2 stage solenoid valve double acting 10000 psi 7l cap. To find the input horsepower requirement for a hydraulic pump use this hydraulic pump horsepower formula. Is this a reasonable idea.
