Low-Flow High-Head Process Pump (OH2 Configuration)
This series of pumps are petrochemical process pumps designed in accordance with API 610 specifications. They are single-stage, horizontal, radially split volute pumps with foot-supported pump bodies. Featuring a single-suction radial impeller, they employ axial suction and radial discharge. Hydraulic balance is achieved through front and rear wear rings and balance holes, depending on operating conditions. The stuffing box incorporates cooling or heating pipe connections. The shaft seal employs a cartridge-type single-face or double-face seal, complete with a cooling flush or seal system. Seal piping is designed per API specifications. The rated pressure class for both suction and discharge flanges is identical. Viewed from the motor end, the pump rotates clockwise.
