纵向的多阶段的离心泵

centrifugal pump DL series pump is the product which our company develop according to the standard of the country aimed at tall buildings water supply, water drainage and fire control. It can convey clean water or similar liquids in physical or chemical properties whose temperature is not higher than 80 centigrade degree. The pump especially applicable for tall buildings fire-fighting water supply and living water supply. It is also applicable for boiler water supply. Because it adopts hydraulic model of IS series pump which is the product saving energy efficiently the country recommend to use, it is efficient. The vertical dividing section structure makes the pump compactly. And it occupys few area of the land. Its rotor is installed vertically. There is no gravity disturbance in the radial direction. So the pump has a smooth running, low noise and long use life. The pumps shaft seal can adopt mechanical seal with sclerotic alloy to ensure nothing let out in motion. The pump is according to the standard of JB/TQ809-89. Structure: DL series pump is vertical structure. It can be set two or three outlets when it is needed. It can also work with one outlet. When there is one outlet, the pumps capacity is rated capacity. When there are two outlets, the total capacity of the two is the pumps rated capacity. It is suitable for the need of pressure dividing water supply of different capacity. The angle between the pumps outlet and inlet can be set 0090018002700 according to the needs. The pump is driven by vertical motor with elastic pin coupling. Looking down from the direction of motor, the rotary direction of the pump is clockwise.
