DG Series Boiler Feed Pump

DG series boiler feed pump is for delivering clean water without solide particle or the liquid which the chemical and physical feature is similar with water and temperature is less than 120℃. It's suitable for boiler feed water and hot water.

Description

DG type water is a single suction multistage segmented centrifugal pump for conveying clean water and liquids similar to water in physical and chemical properties. When the head of this type of water pump is 100 to 1100 meters and the flow rate is 10 to 100 m 3/ hour, the highest temperature of liquid is 110℃, it is suitable for boiler water supply, factories and urban water supply, the DG pump manufactured at present: 50DG50, 65DG50, 80DG50, 100DG100 and so on.

Construction

The multistage pump is consisted of stator, rotor, bearing, shaft seal.

1. Stator: consisted of suction casing, discharge casing and diffuser. The casing are held together by external tie rod.

2. Rotor: consist of shaft, impellers, balance disc and shaft sleeve etc.

3. Bearing parts: consisted of bearing housing, bearing and bearing cover. It's generally rolling bearing lubricated by grease.

4. Shaft seal: packing seal or mechanical seal.
