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

Structure

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.
