Isomag Seals Make Cornell Pump Run Cooler and Last Longer


In 2014, Moores Pump and Services approaches Isomag with a very unique application. The Cornell 2.5 DA-1 cavitation pump, was a pump used on the Gulf Coast oil platforms to pump air and water into the ground. The pump was unique due to its need to seal the bearing housing and a barrier fluid on the discharge end.

The Cornell was initially equipped with labyrinth isolators on the bearing housing and a lip seal on the discharge end holding the barrier fluid. Isomag bearing isolators was initially brought in to seal the barrier fluid only so the pump could lose the reservoir tank. However, Moores Pump decided to go with Isomag bearing seals on the bearing housing as well. After running on the test rig, it was discovered the pump ran 30°F cooler (120° F) at the bearing housing. The combination of the Isomag bearing seals equipped at both ends of the pump has been a smashing success. Now all Cornell pumps are being retrofitted with Isomag bearing isolators every time they come in for repair.
