Split Case Pump

Split Case Pump

1. QS Split Case PumpIntroduction

QS horizontal double suction split casepump, the casing is axially split, which permits removal of the complete rotorwithout moving either piping or motor. Pumps generating high heads have doublevolutes to reduce radial forces. Replaceable wear ring protect the casing atthe impeller running clearances. Vertical or horizontal, soft packing ormechanical seal, grease or oil lubrication bearing on request. It is alsoelectric motor or diesel engine driven on request.

2.QS Split CaseWater Pump Feature

(1)Have QS and QSH two types.

Viewedfrom motor, the direction of the QSH pump is anti-clockwise, that is thesuction in the left, the discharge in the right. The rotating direction of thetype QS pump is clockwise, that is the suction in the right, the discharge inthe left. Also can move the driver to another edge according to the user’srequires. Then, the rotating direction, the suction and discharge direction isin the opposite as the described above.

(2)Supply full set split-casing centrifugal pump, motor, coupling, the inletdiameter less than 200mm match the common base.

(3)The pump is axial split casing construction.

(4)Large capacity
