GSP OH2 API 685 centerline mounted single stage sealless magnetic drive pump.

- Flows to 3,647 gpm (828 m³/hr)
- Heads to 1,146 ft (350 m)

The GSP OH2 pump has no mechanical seals which are widely regarded as the weakest point in any pumping system. Over 85% of pump failures involve mechanical seal failure and leaks through static seals such as gaskets and O-rings as well as bearing failure. When planning a new pump installation or an upgrade to an existing installation, the financial impact of the mechanical seal support system is considerable. The GSP sealless magnetic drive pump meets all of the requirements of API-685 making it ideal for chemical, petrochemical as well as oil and gas installations. 

Our heavy duty line of API sealless magnetic drive, end suction centrifugal pumps comply with specifications required by the oil, gas, petroleum and heavy chemical industries. The GSP is typically used in toxic, aggressive, hot, crystallizing and high value processes.
