Precautions for slurry pump selection

Precautions for slurry pump selection

Slurry pump selection is a demonstration of the comprehensive strength of a slurry pump manufacturer,it directly affects the future production of users

Choosing the appropriate slurry pump for the user not only meets the customer’s operating requirements, but also saves the customer’s operating costs.

The user's suitable slurry pump should compound the following conditions:

1. While meeting the operating requirements, the initial purchase cost is low (large slurry pumps cannot be recommended for profit when there are small ones)

2. In the process of production and operation, the service life is long, and the pump type is too small, which will cause overload operation, accelerate the damage of the flow parts, and increase the production cost.

3. Considering the convenience of later maintenance, the national standard slurry pump is recommended to make it convenient for customers to purchase replacement parts and prevent delays in production due to repairs.

The selection of the slurry pump directly affects the life and stability of the slurry pump

The following factors are mainly considered in the selection process of slurry pump:

1. First consider the layout of industrial and mining equipment, topographical conditions,water level conditions,Comprehensive factors such as operating conditions, economic solutions, and whether customers have special requirements.

2. Secondly consider choosing a horizontal slurry pump or a vertical slurry pump

Features of horizontal slurry pump: easy to disassemble and assemble, easy to manage, but large in size and expensive, requiring a large area;

Vertical slurry pump features: a. In many cases, the impeller is submerged in the water, b. It can be started at any time, c. It is convenient for automatic or remote control, d. It is compact, e. The installation area is small, and f. The price is cheaper.

3. According to the concentration of the slurry, the size of the particles, and the PH value, determine whether to choose a corrosion-resistant slurry pump or a wear-resistant slurry pump, and choose rubber flow parts or metal alloy flow parts (A05/A07/A33/A49).For pumps installed in explosive areas, explosion-proof motors should also be used according to the level of the explosive area.

According to the conditions of flow, head, slurry, pipeline, etc., refer to the slurry pump type spectrum and performance curve to select the specific applicable model.

Principles of slurry pump selection:

1. Make the type and performance of the selected pump meet the requirements of process parameters such as device flow, head, pressure, temperature, NPSH, and suction.

2. High mechanical reliability, low noise and low vibration

3. Economically, the total cost of equipment costs, operating costs, maintenance costs, and management costs should be taken into account as the lowest.
