1、 Overview

Stainless steel pumps can transport various media from tap water to industrial liquids

2、 Application scope

The IHK/KHK stainless steel pump is suitable for transporting suspended liquid media containing a certain amount of solid particles in biological products, or corrosive liquid media.

Mainly used for:

Pumps used in biomass energy plants, such as those used in starch, starch sugar, glutamic acid, alcohol (ethanol, propylene glycol) and other sectors;

Pumps used in petroleum refining, petroleum transportation equipment, and chemical deep processing equipment for transporting corrosive media;

Pumps for water supply and seawater desalination systems;

Pumps for sewage treatment and environmental protection systems;

Coal chemical pumps.

3、 Using parameters

Flow range: 12.5-1000m3/h Working pressure: 0.02-2.5MPa

Head range: 8-260m Transport medium temperature: IHK type is -10 ℃~120 ℃ KHK type is -40 ℃~260 ℃

4、 Structural features

The IHK/KHK stainless steel pump is a single-stage single suction cantilever centrifugal pump, with a horizontal axis suction center and a vertical upward discharge. Adopting a rear door structure, which is characterized by easy maintenance,

When disassembling and repairing the pump, it is not necessary to remove the suction and discharge pipeline flanges of the pump. The impeller, sealing ring, mechanical seal, bearings and other components of the pump can be replaced.

The KHK type sealed chamber is equipped with an external water-cooled chamber, and the bearing suspension components are also equipped with optional water-cooled jackets, making it suitable for transporting medium to high temperature (-40 ℃ -260 ℃) liquid media

Quality. The bearing suspension components use two sets of back-to-back radial thrust ball bearings to balance residual axial forces and lubricate with a thin oil pool.

There are two ways to balance the axial force of a pump, one is through the auxiliary blades, and the other is through the balance holes. Due to the effect of the auxiliary blades, it can not only reduce the pressure in the sealing chamber, but also

It can reduce the concentration of solid particles in the sealed chamber and improve the service life of mechanical seals. The shaft seal of the pump can use packing seal, single end mechanical seal or double end mechanical seal

Various sealing forms such as sealing. The hydraulic design of the pump is advanced, energy-saving, and the high flow pump adopts a double vortex chamber design to balance radial forces, ensuring smooth operation of the pump. Improve the pump's performance

Operational reliability. The design of the pump shaft meets the design requirements of AP1610 rigid shaft; Pump direction: When viewed from the motor end, the pump rotates clockwise.
