IH Stainless Steel Centrifugal Cheemical Pump
Type IH pump is single-stage and single-suction (axial suction) corrosion resistant centrifugal pump, which is suitable for pumping corrosive liquid without solid particles or other liquid whose consistency is similar to that of clean water. The temperature of medium is -20～105℃, 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.
Type IH pump is designed by National pump Industry according to ISO Standard, which has many advantages such as wider range of properties, higher efficiency and convenient maintenance. Its efficiency is average higher 2% than type F pump can be described as energy saving product popularized by the government.
Type IH serial pump have 40 basic types, among which there are 33 double speed (2900 and 11450r/min) can reach 112 specifications after cutting impeller diameter of type A and B.
The property and dimension of type IH pump are designed according to the International Standard ISO2858.The pump is made up of casing, pump cover, impeller, shaft, sealing ring, middle support, sealing and hanging parts.
The casing and cover make up the working room of pump, the inlet of casing is horizontal, and the outlet is vertical. The cover is clipped between the casing and middle support. The hanging part is fixed on the middle support. The impeller, shaft and bearing are the rotors of pump, and rotor is supported by the hanging and bearing parts. The pump is back - opening structure with extended coupling. The advantage is it can be conveniently repaired. It´s not necessary to take apart the casing pipeline and motor, only take apart the middle connector of the extended coupling, the rotor can be taken down for repairing.
Bearing: There are two single - row centripetal ball bearings in the hanging part to support the pump shaft and bear the radial and axial force of pump.
Shaft sealing: There´s filling sealing or mechanical sealing‘ Filling sealing: There’ s filling box in the cover, and the soft filling sealing is used. The water of certain pressure can pass through the filling box for sealing, cooling or cleaning.
Mechanical sealing: The single or double end mechanical sealing can be selected according to the requirements. The water of certain pressure can pass through the sealing box to wash the rubbing end which has cooling function.
Revolution: The pump is directly driven by the motor through extended coupling. The pump revolves at clockwise when viewed from the direction of motor.
The customers can select the material of main parts according to operating conditions.
