ELECTRIC MOTOR SELECTION FOR A PCP PUMPS
ELECTRIC MOTOR SELECTION FOR A PCP PUMPS
(OP)
Hi,
I would like to get some information about how to select the right electric motor for an oil pcp pump application.
My client has a 50 HP motor and they need to change this, but they think that this motor is to high for their application.
Best regard,
Neca.

In cases with high sand cut or high viscosity (heavy oil or emulsions) the starting torque could be way above the value obtained from a computer simulation. This should be taken into account for the rod string size/material and Motor power.
The main problems of having an oversized motor are the risk of breaking the rods and the difficulties to diagnose or protect the system based on current (amps) meassurement, since its sensitivity to operational conditions will be mask by the low efficiency you will find at low % of load.
good luck,
