Slurry pump impeller introduction:
The impeller of the slurry pump refers to the wheel equipped with a moving blade, and refers to the general term of the wheel and the rotating blade mounted on it. Impeller is a key component of slurry pump, which is a rotary body with blades to transfer energy to liquid. It is composed of several curved blades.
Impeller action:
The role of the impeller is to transfer the mechanical energy of the prime mover directly to the liquid to improve the static pressure energy and dynamic pressure energy of the liquid.
Slurry pump impeller material:
Wear and corrosion resistant high chromium alloy (A05, A07, A33, A49), also has rubber impeller, polyurethane impeller
Classification and function of impeller of slurry pump:
1, slurry pump impeller according to the mechanical structure mainly has the following forms: closed, semi-closed, open.
(1) Closed impeller
It is composed of a blade and a front and rear cover plate. Closed impeller has high efficiency, difficult to manufacture, and is most used in centrifugal pumps. Suitable for transporting clean water, solution and other small viscosity without particles of clean liquid.
(2) semi-closed impeller
The semi-closed impeller is suitable for conveying materials that are easy to precipitate or slightly contain particles, and its efficiency is lower than that of the closed impeller
(3) Open impeller
The impeller with only the blade and no complete cover plate is called the open impeller, the open impeller is suitable for conveying materials containing more suspended substances, its efficiency is low, and the pressure of the liquid is not high.
2, according to its suction mode can be divided into single suction and double suction.
(1) The single suction type has a simple structure, and the liquid is only inhaled from one side;
(2) The double-suction structure is more complex, the liquid is inhaled from both sides, and has a large suction capacity.
3. According to the shape of the blade, it is divided into backward curved blade, radial blade and forward curved blade. Because the backward curved blade can obtain higher static pressure energy, the backward curved blade is mostly used in the slurry pump.
4, the impeller of the slurry pump is the work part of the slurry pump, which transfers energy through rotation
5, in the slurry pump selection design can also be through the slurry pump impeller diameter cutting to achieve the appropriate flow and head
6. The impeller of the slurry pump is the part that does the work in the flow part of the slurry pump and is the part that is worn.

1. High chromium alloy A05: The grade of this material is: KmTBCr26, referred to as Cr26 (chromium 26), = This material is more wear-resistant, suitable for a variety of conditions.
2. High chromium alloy A07: This material is more wear-resistant than A05, and its chromium content is a little higher than A05. More suitable for strong abrasive field prices will also be higher than A05.
3. High chromium alloy A49: This material is more corrosion resistant and acid resistant than the material of A05 and A07, and is used more in general desulfurization projects. Power plants, metallurgy and so on.
These metal impelers, A05 material price civilian, wear resistance can be applied to general conditions, so the A05 impeller is the most used in the slurry pump. If we have a high concentration of grout, a lot of particles, and you want more wear resistance then use A07. If the slurry and acidity are relatively large and corrosive, you can choose A49 material. It's just that the price will be higher than the A05. You can choose according to the needs of the scene.
4. Rubber material: This material is made of metal skeleton, lined with a layer of wear-resistant rubber. This material is suitable for the use of particles without sharp corners in the slurry. It will cost a little less than metal. It is used more in sewage treatment projects.
5. Ceramic lining material: This material is the same as rubber material, only the rubber lining is changed to ceramic, this material is relatively corrosion-resistant but not wear-resistant, and the cost is higher.
