How should one select the appropriate chemical pumps and sewage pumps for industrial wastewater projects?
2026-10-30
In the chemical industry, municipal sewage treatment, and industrial wastewater management, the stability of fluid transport systems is critical. The failure of even a single pump can lead to environmental incidents, costly downtime, and safety risks. Selecting the appropriate pump—whether it is a corrosion-resistant chemical pump, a heavy-duty centrifugal pump, or a specialized sewage pump—requires a clear understanding of the fluid's chemical properties, solids content, and hydraulic parameters.
1. Selecting the Right Chemical Pump for Corrosive Media: When handling acids, alkalis, or highly corrosive chemical liquids, material compatibility must be carefully evaluated. Stainless steel (grades 304, 316, or 316L) is suitable for mildly to moderately corrosive media and organic solvents. For strong acids (such as concentrated sulfuric or hydrochloric acid), fluoroplastic-lined pumps offer excellent chemical inertness, effectively eliminating the risk of internal corrosion.
2. Overcoming Clogging in Industrial Sewage Pumps: Municipal sewage and industrial wastewater often contain fibers, rags, and suspended solids, which can easily cause standard clean-water pumps to clog or become entangled. Anti-clogging impeller designs—such as semi-open or vortex-type impellers—allow large solids and fibrous debris to pass through without causing blockages. For deep sumps or heavy sludge applications, vertical submerged pumps (such as the FY series) keep the motor above the liquid level, ensuring safe, reliable, and easy-to-maintain operation.
3. Checklist for Pump Selection: When drafting technical specifications or submitting inquiries to manufacturers,
please ensure the following key parameters are provided:
1 Flow rate and head: Specify the required rated operating conditions and total head.
2 Fluid characteristics: Specific gravity, viscosity, temperature, and pH value.
3 Solids content: Maximum particle size and the weight percentage of suspended solids.

Principles and steps of pump selection
Pumps are a kind of general-purpose mechanical equipment with a wide range of applications. They are widely used in various sectors such as petroleum, chemical industry, electric power metallurgy, mining, shipbuilding, light industry, agriculture, civil and national defense, and they play an important role in the national economy. According to statistics in 2002, the output of pumps in my country reached more than 2 million units, and the power consumption of pumps accounted for more than 21% of the power consumption. Therefore, it is of great significance to greatly reduce the energy consumption of pumps for energy conservation.

Desulfurization pump is a kind of pump with a very wide range of applications.
Desulfurization pump is a kind of pump that can adapt to various working conditions, such as conveying acid, alkaline liquid or slurry; various corrosive slurries in the smelting industry; various dilute acids in the sulfuric acid industry; various sewage in the environmental protection industry, etc. This pump is both corrosion-resistant and wear-resistant, and has a wide range of uses. It has the following characteristics:
What are the common causes and solutions for slurry pump failures?
As a professional slurry pump manufacturer, we remind you: before starting, you should open the pump inlet valve and close the pump outlet valve. Then start the pump, and then slowly open the pump outlet valve after the pump starts. The size and speed of the pump outlet valve opening should be controlled by the pump not vibrating and the motor not exceeding the rated current.
