QS-Diesel Engine Split Case Pump


1.QS Diesel engine Split Case Pump introduction


QS Horizontal diesel engine split case pump, the casing is axially split, which permits removal of the complete rotor without moving either piping or motor. Pumps generating high heads have double volutes to reduce radial forces. Replaceable wear ring protect the casing at the impeller running clearances. Vertical or horizontal, soft packing or mechanical seal, grease or oil lubrication bearing on request. It is also electric motor or diesel engine driven on request.


2.QS Diesel engine Split Case Pump Feature

(1) Have QS and QSH two types.
Viewed from drive engine, the direction of the QSH pump is anti-clockwise, that is the suction in the left, the discharge in the right. The rotating direction of the type QS pump is clockwise, that is the suction in the right, the discharge in the left. Also can move the driver to another edge according to the user’s requires. Then, the rotating direction, the suction and discharge direction is in the opposite as the described above.
(2) Supply full set split-casing centrifugal pump, motor, coupling, the inlet diameter less than 200mm match the common base.
(3) The pump is axial split casing construction.
(4) Large capacity
