G type boiler feed pumps
introductions
G type boiler feed pump is used for conveying clean water and physical and chemical properties similar to water liquids. This type of pump head at 46-576 meters, flow is 6-55 meters/hour, the highest temperature of liquid below 110 degrees, it is suitable for boiler water supply, factory and urban water supply. Pump equipped with Y motor. Currently G type pump: 11/2G-5，21/2G6 and 4G8 four kinds.
structural declaration
G type water pump is multi-stage segmental type, its suction inlet lies on the inlet inflow section, suction outlet on the outlet section, both vertical up, its head according to usage to increase or reduce pump series. Whether the pump is well installed will influence the performacne greatly, especially impeller outlet and lead inlet relative position, every stage impeller output centre must aim the centre od the lead impeller, if there is deviation, the flow is reduced, head is reduced, efficiency is worse, so must attention when repairing, and must adjust if there is a deviation.
