QIH Chemical and Acid Pump

The QIH series chemical and acid pump is the energy saving type pump used to transport corrosive liquid like the acid of the viscosity similar to water without solid particles, being able to for thechemical industry, petroleum, metallurgical industry, paper making, food, pharmaceutical industry and compound fabric industry etc.. The QIH chemical and acid pump's dimensions is designed according to the standard of ISO2858、ISO3069、ISO3661. It has such characteristics as wide range of performance, high efficiency and easy to maintenance etc., speical designed for the acid and the other cheimcal processing. The QIH energy saving type chemical and acid pump recommended by the Mechanical Industry Department of Chinese government for its efficiency being 5% greater than F type corrosion resisting pump!

QIH chemical and acid pump is the single stage, end suction, axial suction, cantilever centrifugal pump.

The temperature of transported media of QIH model chemical and acid pump is -20℃~+105℃. Through adopting cooling method, it can transport media with higher temperature if necessary, and is applied to transport various corrosive media like acid 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.

Capacity 6.3-400m3/h
Head 5-125m
Speed 2900r/min and 1450r/min
Power of fitted motor 0.55-90kW
Inlet diameter 50-200mm
The highest work pressure 1.6MPa

QIH model chemical and acid pumps are classified as 29 basic types, 22 of them with two speed (2900, 1450 r/min) could be transformed after cut by the impeller diameter of A and B models to get the total 112 different type of pumps.

1. QIH model chemcial and acid pumps are the series of products designed according to ISO international standards in all industries in China. 

It is mainly composed of pump body, impellers, seal rings, 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 & output 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: 

The 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 seal ing, 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 washing and 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 ISO 3069 as required, are allowed, such as mechanical seals of corrugated pipes, assistant impeller seals and so on.
