IH Model Single-stage Single-suction Cantilever Type Chemical Centrifugal Pump

Description :

IH model chemical pump is single-stage end-suction (axial suction) cantilever type centrifugal pump，which is used to transport corrosive liquid with viscosity similar to water and without solid particles. The marked and rated performances and dimensions adopt ISO2858 international standard . lt has such characteristics as wide range of performance , high efficiency , high mechanical，chemical and physical level and convenient maintenance etc . lt is energy saving type product recommended by the nation with its efficiency being 5% greater than that of F model pump. The temperature of transported media of lH model chemical pump is -20℃ to 105℃ . Through adopting cooling method , it can transport media with higher temperature if necessary，and is applied to transport various corrosive media or media in which pollution is forbidden similar to water in such industries as chemical industry , petroleum，metallurgy，electric power . papermaking , food , pharmacy and synthetic fiber etc.

Key Features :

1. lH model pumps are the series of products designed according to lSO international standards in all industries in China. It is mainly composed of pump body , impellers , searings , impeller nuts , pump cover , seal parts , intermediate support , spindle , suspended parts and so on.
2 . Structural features : The pump cover is fixed on the intermediate support , and the pump cover is clamped in the middle by coupling between pump body and intermediate support . On the pump body , water is input axially and output radially. Support feet can be fixed on the base directly. The suspended parts are fixed onto the intermediate support through the rabbet , and are supported onto the base by suspended frame . To make it convenient to disassemble . the prolonged coupling is designed , so that it is unnecessary to disassemble the coupled input & ouput pipes during check and maintenance. To pump body and motor , only by disassembling the intermediate coupler of the prolonged coupling , users are able to screw out rotor part for check and maintenance , which is a conventional structural pattern in the world.
3 . Rotation direction : The pump is driven by motor directly through a prolonged coupling , seen from the side of the motor , it rotates clockwise.
4 . Spindle seal patterns : Spindle seal patterns of pump are of two types such as stuffing seal and mechanical seal . The stuffing seal is that on stuffing case in pump cover , with software stuffing for sealing , input water of a certain pressure into the stuffing case, for cooling , lubrication and cleaning on seal , mechanical seal is of two types such as single-surface mechanical seal and double-surface mechanical seal , input water of a certain pressure into the seal chamber , for washingand cooling on the abrased surfaces. Seal patterns of pump are of stuffing seal or mechanical seal , according to users' requirements , in a same time , seal chamber sizes and shaft gland patterns of other structures according to lSO3069 as required , are allowed , such as mechanical seals of corrugated pipes , assistant impeller seals and soon .
