Gusher Pump Eliminates Mechanical Seal Failures

OTP Industrial Solutions for Pump Applications

An automotive components plant was having trouble with a horizontal base mounted pump in its machining process.  This pump was used to circulate 176 degree Fahrenheit quench oil through a filter and back to a collection tank.  The hot oil with suspended metal fines caused frequent mechanical seal failures which resulted in regular oil leakage.  After some time, the performance got so bad that the customer actually remounted the pump inside a basin to collect the ongoing oil leakage.

When the customer first contacted us, we considered replacing the pump with a Gusher vertical immersion pump, which we have often used successfully in similar applications.  However, there was not enough room inside the tank to mount the pump.

After reviewing the application further, we installed a Gusher 7550 EC series vertical pump .  We selected this pump because its enclosed column allows it to be mounted outside the tank and it was not fitted with a mechanical seal.  Its jacketed ball bearing housing is ideal for high temperature applications.  Although this pump initially cost three times more than the pump it replaced, it quickly provided maintenance cost savings by eliminating seal failures and the resulting mess of a leaking pump.

We installed the first Gusher pump over three years ago and it is still running with no problems.  The  customer has since purchased two more pumps for similar service in other areas of the plant and is now looking into making this pump a standard at their other manufacturings plants.

Gusher Pump proved again to be a good partner with just the right pump to solve any application.
