DG Multi-Suction Centrifugal Pump

Product Application

DG series is horizontal end suction multistage centrifugal pump,suitable for transfering clear water with below concentration of 0.1% and solid diameter of 0.5mm,or similar water from property of physics and chemistry.This pump is with high efficiency,energy saving and reliable performance.Specially suitable for boiler feed and other transfer hot water.

DG series pump transfer media temperature below 120 degree.

With a wide range, good quality, reasonable prices and stylish designs, our products are extensively used in Factories, mines, urban water supplies, power stations, water conservancy projects, agricultural irrigation, fire control systems, Marine industrial mining, etc 

Main Features

Assembly and Disassembly 
Whether the pump is assembled correctly affects its performance greatly. The outlet center line of the impellers must be aligned to its inlet center line, and the overall performance will be affected and the efficiency will be reduced consequently if there is a slight deviation, therefore, the sealing clearances between the rotary part and the fixed part should meet the specification. If the clearance is too small, the service life of the pump will be shortened by wear of components and vibration of pump; if the clearance is too large, the pump’s efficiency will be lowered down by the growing leakage. Assembly and disassembly of the pump must be carried out according to the General Assembly Drawing. 

Installation 
Apart from the general installation requirements, note that:
1. The motor and the pump’s coupling should be spaced for a clearance approximate to displacement of the pump shaft. 
2. The shaft axis of motor and the pump should be in a horizontal line.
