SEPARATION SOLUTIONS

System Integration

Elgin’s integrated waste management and solids

treatment systems integrate PC feed

pumps directly into the package, therefore, reducing installation

and erection headache.

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 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) and a variety of motor installation configurations (i.e. in-line, offset, and “piggy-back”).

System Mobility

As a result of their small footprint,

the integration of PC pumps can be

efficiently integrated into mobile

treatment system packages.

Though each centrifuge feed PC pump supplied by Elgin comes standard with a Nord™ gear box and premium motor, alternatives are available upon request. The following table highlights the standard electrical configuration of Elgin’s centrifuge feed PC pumps.

Improved MaintenanceFull drive train,

including stator, rotor, rod, and seal can be removed in minutes without electrically disconnecting the

pump. Maintenance can be conducted in a matter of minutes,

instead of hours.

Constant Parameters

Operation parameters are unaffected, since the design has no effect on flow and

pressure. Regardless of the operating

conditions, you will receive a consistent

output.

Extended LifeDue to the low

running speeds of the pump, there is a

significant reduction in equipment wear.

Easy to ServiceNo special tools are

required, as the pump can be serviced with only a wrench and an

allen key.

Split CouplingThe split coupling body provides a

quick and easy way to disassemble and maintain the pump.




Select Floc™ LP3 Chemical InjectionDue to their ability to ensure a consistent volumetric output,

regardless of the viscosity or specific gravity, Elgin uses PC pumps for all of its mobile chemical

injection systems.

Packaged Dewatering Systems

Fully integrated PC pumps are used in all of Elgin’s dewatering

systems to careful control the volume of hydrated polymer introduced into

the drilling fluid
