The WD, WDF, WG and WGF type sewage pump are designed according to Centrifugal Sewage Pump Standard . The pump has advanced design, compact structure, small volume and high efficiency. It is a kind of high-efficiency and energy-saving sewage pump. the WD and WG type pump are applicable to feed sewage, excrement and liquid with fibers or suspend substances (the size can not exceed 80 % of the outlet caliber) below 80℃ .
The overcurrent components of WDF and WGF pump are made by stainless steel. Therefore, the pump is applicable to feed water with acidity, alkalinity and other corrosiveness for chemical liquid feeding in chemical industry and scientific research institutes with feeding temperature of below 80℃ . The outlet direction of the WD, WDF, WG and WGF type pump can be changed according with 45° space. Generally, the pump adopts shaft seal. The F-type corrosion-resisting pump adopts acid-resisting asbestos filling or mechanical sealing.
