Product Overview
G-type boiler feed water pump for conveying clean water and liquids with physical and chemical properties similar to water.
This type of pump has a head lift of 46 to 576 meters and a flow rate of 6 to 55 meters per hour. The maximum temperature of the liquid is less than 110. It is suitable for pot water supply, water treatment and water supply. The pump is equipped with a Y-type motor.
The G-type pumps currently manufactured include: 11/2G-5, 21/2G6 and 4G8.

Structure description
The G-type pump is multi-stage segmented type, the suction port is located on the water inlet section, and the discharge port is vertically upward on the water outlet section, and the lifter increases or decreases the number of pump stages according to the use. The pump assembly is good, and it has a great influence on the performance. Especially, the outlet of each impeller and the inlet of the vane are better than the position. The center of the spout of each impeller must be aligned with the center of the vane, and a slight deviation will make the water The segments are straight up, and the lift can increase or decrease the number of pump stages according to the use. Whether the pump is assembled well or not has a great influence on the performance, especially the relative position of the outlet of each impeller and the inlet of the vane. The center of the spout of each impeller must be aligned with the center of the vane, and a slight deviation will make the pump The flow rate is reduced, the lift is reduced, and the efficiency is poor. Therefore, it is necessary to pay attention to the inspection and assembly. If there is a deviation, it must be adjusted.
