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.
