Factory Service

NASH Certified Service Centers are the only centers authorized to offer OEM parts, factory trained technicians, and patented upgrades that provide NASH quality service and repair at a competitive price.

Some companies claim to offer service, but take shortcuts, reuse parts and do not repair the product to OEM specs. Considering another service shop - why risk it? Sub-par repairs can lead to costly downtime, pump and system failure, and lost production.

Inspections

Liquid ring pumps are disassembled or fiberscope inspected, and the cause of failure is determined. This enables Gardner Denver Nash to provide you with information as to why the pump failed, to take corrective action and to determine the best type of repair for your particular application in order to extend pump life. A firm quote for repair is prepared and sent to you. Options quoting can also be made, and you determine the method of repair.

Materials

All new remanufactured and repaired parts meet current specifications. As improvements are made to a particular part for better pump performance, your pump will be upgraded automatically. All stainless material used in the lining of parts is "L" grade only, 304L or 316L as specified. New components when required are original Gardner Denver Nash castings.
