Diesel engine double suction pump

■Flow rate：Q=20~12000m3/h

■Total head：H=9~105m

■Speed：n=585rpm/2950rpm

■S.g.：γ ≤1.15

■Temperature：T=--10～105℃

■The installation of COS series pump can be horizontal and vertical, and for the horizontal one, the driver can be in the left and right according to the user’s requires.

■The flange hole can according to the GB, ISO, DIN, or ASI standard.

■The two sides of horizontal one can adopt the grease lubrication bearing and the dilute oil lubrication, the down side is SIC wear resistant sliding bearing.

■According to the user’s need, the pump rotating direction can be the clockwise or counterclockwise.

■Single stage,double suction,axial split casing centrifugal pump.Double passage casing to reduce the axial forces.

■Both pump inlet and outlet are beneath the pump centerline,the rotary part can be removed from the casing without dismantle the pipelines.

■Shortened shaft and enlarged diameter of shaft design to increase the life of bearings and mechanical seals.

■Completely sealed shaft design, zero contact with fluids.

■Various materials of shaft sleeve to prevent the shaft from abrasion and corrosion.

■Both mechanical seal and packing seal are available;mechanical seal can be changed without dismantle the pump cover.

■Different rotation directions are available.

Structure drawing is as below:
