OH3 Series DVSS Pumps

Vertical In-line Process Pump. 

For petroleum refining, production and distribution. For petrochemical, chemical and other applications. The DVSS design is according to API 610 latest edition, with mechanical seal chamber in accordance with API 682.

The pump is suitable for being directly mounted into the piping being supported by an integral compact mounting foot, without the need of a foundation. The residual hydraulic axial thrusts are absorbed by a pump mounted heavy duty Thrust Bearing assembly. This pump is designed to handle a wide range of process fluids and has one of the broadest hydraulic coverage in the industry.
