Multistage centrifugal pump product instruction
Multistage centrifugal pump can be used in the factory, mine drainage, city sewage plants and other fields, can transport themedium containing solid particles content should not be greater than 1.5% and similar wastewater, the transported medium temperature should not exceed 80 ℃, if exceed this temperature will need to takespecial means of cooling water for cooling. With high efficiency, wide range of performance, safety and stable operation, low noise,convenient installation advantages of repair, long operating life etc..
MD type multistage centrifugal pump is composed of pump body,impeller, shaft, balance disc, the inlet and outlet section, wherein thepump shaft material can be used 45#, 2Cr13, pump the whole material can use cast iron, cast steel, stainless steel three kinds ofmaterial according to the needs of users. Cast iron, cast steel,stainless steel three.
Multistage centrifugal pump service condition
In clear water conditions (containing solid particles less than 0.1%),run 5000h without overhaul, decreased efficiency of not more than 6%.
