Think You're Saving With An Unauthorized Repair Shop? Think Again.

One operator found out the hard way - only NASH Certified Service™ provides the quality and reliability of the original OEM manufacturer.

A customer brought in a NASH 2BE1 liquid ring vacuum pump that had locked up. When one of the industry's most reliable pumps fails, you know something is wrong. Our comprehensive disassembly and inspection of the unit revealed what we suspected - the root cause of the pump failure was improper repair work and assembly by an unauthorized repair center.

Here is what we found and documented in the failure report:

  • The fixed end was modified and didn't properly fit the idle end of the pump. This caused the rotor and shaft assembly to float back and forth, and making contact with the portplates. 
  • The shaft had been fabricated and was not made to OEM drawing specifications. 
  • Both portplates were badly grooved and no longer flat. 
  • The rotor faces were badly grooved and the rotor had been cut shorter than standard length. This doubled the pump end travel from the standard OEM dimension. 
  • The bearing brackets were modified and couldn't be reused. 
  • The fixed end brackets backside had been completely machined off.
  • Ball bearings were installed instead of the standard roller bearings.

Damage to rotor and port plate
The rotor and portplates of this 2BE1 pump were badly grooved as a result of improper repair and assembly performed by an unauthorized repair shop.

The result: a pump that is not operational and cannot be repaired.

This customer sent their pump to an unauthorized repair shop hoping to save money. Instead, this decision cost them thousands of dollars in lost production due to unscheduled downtime and the cost of a replacement pump
