How to calculate the motor power of metering pump?
The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
The motor power of the metering pump is divided into two parts1. mechanical power, this part of the power metering pump design part will be some data, mainly to control the mechanical structure of the metering pump required power
