Progressive Cavity Feed Pumps

PC Pumps


To ensure a well-balanced feed with consistent feed pressure, Elgin can supply a variety of custom-configured progressive-cavity feed pumps (“PC pumps”).  PC pumps can improve the centrifuge performance, extend the life of a centrifuge and reduce overall operations and maintenance costs when properly operated.


Elgin PC pump packages can be supplied in a variety of skid configurations (i.e. wide field skid and narrow plant skid), as a mechanically-variable gearbox or a direct gearbox with inverter-duty, VFD-driven motor, and a variety of motor installation configurations (i.e. in-line, offset, and “piggy-back”).


Elgin’s PC pumps are mated with a Nord™ gearbox and premium, continuous duty, energy-efficient, explosion-proof motor (non-explosion proof motors are for applications requiring UL or CSA certification for hazardous locations.

Elgin PC Pump Benefits:


Improved Maintenance

Full drive train, including stator, rotor, rod, and seal can be removed in minutes without electrically discon-necting the pump.  Maintenance can be conducted in a matter of minutes, instead of hours.


Constant Parameters

Continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity.


Extended Life

Due to the low running speeds of the pump, there is a significant reduction in equipment wear.


Easy to Service

No special tools are required, as the pump can be serviced with only a wrench and an allen key.


Split Coupling

The split coupling body provides a quick and easy way to disassemble and maintain the pump.
