Prime Machine Inc. specializes in the rebuild of large circulating water pumps.

Our shop has the qualified personnel, crane capacity, and machines to complete a quality rebuild including:

Transportation to the shop on our dedicated semi truck for direct route transportation to and from the shop.

Millwrights experienced in the disassembly and assembly of large rotating equipment.

Column and discharge head repairs:

Welding and machining of registered fits

All registers and bearing housing are verified to be straight using our laser tracker system.

Repairing of all bearing fits

and a packing case are critical to the alignment of the pump for improved operation producing less friction and vibration. This requires large capacity machining and is completed on our froreip vertical boring mill.

Impellor repairs include:

Welding of worn areas

Repair of all leading and trailing edge cavitation areas

Full Machining on our CNC

Machines

Dynamic balancing of rotating components

Impellors are machined on our computer numerically controlled machines to provide the exact clearance required between the impellor and impellor liner to yield the maximum efficiency. The machining is three dimensionally verified by our laser tracker system. Complete quality reports are provided graphically to represent the clearance.

Impellor liner bowl repairs include:

Welding of worn areas

Machining on our CNC

Machines

Laser tracker three-dimensional inspection of profile to insure the bowl to liner fit is correct yielding efficient pumping.

Shaft repairs include:

verification of straightness

measurement bearing journal sizes

metal spraying of bearing fits

Certified balance technicians to provide an impellor with balance in two planes complete dynamic balance of the impellor.

Coatings of epoxy paint are applied that provide protection to both the exterior and interior of the pump.

Our circulating pump repairs yield maximum flow with minimum power draw. Restoring cooling capacity to condense the steam and reduce backpressure on the turbine. The power draw to run the pump is reduced creating more overall efficiency for the power plant.
