Type IH pump is single-stage and single-suction(axial suction) corrosion - resisting centrifugal pump, which pumps corrosive liquid without solid particle and glueness similar to water.The temperature of medium is -20°c 105°c if necessary,cooling measure can be taken to reach a higher temperature. It applies to petroleum,chemical,metallurgical,power, paper making,foodstuff,pharmaceutical,and synthetic fiber industry,etc. Range of properties:Capacity(Q):0.3-400m3/h Head(H):5-125m Rotational speed(n):2900,1450r/min Power:0.55-90kw Inlet diameter:32-200mm Max.operating perssure:1.6Mpa Type IH pump is designed by National pump Industry according to ISO2858 Standard,which has many advantages such as wider range of properties,higher efficiency,and convenient maintenance. Type IH serial pump have 40 basic types,among which there are 33 double speed(2900,1450r/min),and can reach 112 specification after cutting impeller diameter of type A and B.
