How to Calculate Water Pump Horsepower

A pump is a basic but important mechanical device that supplies the force to move fluid at a specific flow rate. Like any device that does work (transfers energy across a distance), its effectiveness is measured in power. Although watts and kilowatts are more common units of power measurement, horsepower is still commonly used for high-output electrical devices in the United States. In this context, 1 horsepower is equal to 746 watts.

• Water horsepower = minimum power required to run water pump
• TDH = Total Dynamic Head = Vertical distance liquid travels (in feet) + friction loss from pipe
• Q = flow rate of liquid in gallons per minute
• SG = specific gravity of liquid (this equals 1 if you are pumping water)
• Water horsepower = {displaystyle {frac {TDH*Q*SG}{3960}}}
• Actual power required = (water horsepower) / (pump efficiency).

The main data for slurry pump

Horsepower—When reporting a problem on a centrifugal pump, the customer needs to tell the repair technician the exact electric motor nameplate data in terms of horsepower. If the horsepower is less than what the pump actually requires, this could create a significant problem in the electric motor, and a performance problem with the pump itself.

Speed—The speed is vital to know because the motor would have been specified for a pump at a particular speed.

Voltage rating/enclosure—The voltage ratings on the nameplate, as well as the enclosure style, are all important to know as well. For instance, an open-drip-proof motor (ODP) has a different service factor than an explosion-proof motor.

Service factor/full load amps—Another important piece of information for the service technician is the service factor, as expressed in full load amps. The technician will want to compare his amperage readings to those on the nameplate.
