2. Product overview
D pump is single-suction multi-stage sub-type centrifugal pump, and it is used to suction deliver water and the other liquid whose physical and chemical properties similar to water. If Change the material of impeller , seal ring, shaft sleeve and other parts, they also can be used to pump corrosive media, the liquid maximum temperature should not exceed 80 centigrade.
MD wear-resistant multi-stage centrifugal pump is a wear-resistant multi-stage centrifugal pump designed on the basis of D single-suction multi-stage water centrifugal pump .MD pump is efficient , energy saving , wear-resistant and reliable, pump the mine well water whose solid particle content is no more than 1.55 ( particles diameter less than 0.5mm) and other similar liquid, the liquid temperature not exceed 80 centigrade.
