Petrochemical & Petroleum Industry API 685 – GSP

General Service Petroleum API 685

Meeting the needs of refineries and petrochemical plants worldwide

The GSP is a heavy-duty horizontal centre-line mounted sealless magnet drive pump that fully complies with the API 685 standard (sealless equivalent to API 610).

Covering an extensive range of hydraulics and application requirements, the GSP provides all of the benefits associated with its simple, reliable and site serviceable design whilst delivering the highest levels of safety and environmental protection.

The GSP is available in standard 316L Stainless Steel materials as well as alternative metallurgies including Alloy C22 / C276 and Duplex, along with a number of engineered design options to meet the needs of the most challenging of pump applications.
