A chemical centrifugal pump is a fluid transfer device specifically used in the chemical industry, relying on the centrifugal force of the impeller to move the medium. Chemical centrifugal pumps are designed for corrosive and high-temperature industrial conditions and can handle special fluids like acids, alkalis, solvents, and wastewater. They're widely used in industries such as chemicals, environmental protection, and metallurgy.
 
Ⅰ. Features of Chemical Centrifugal Pumps
Chemical centrifugal pumps have a sturdy structure and run smoothly, with low vibration and noise, and provide a steady and uniform flow. The equipment can be made with various corrosion-resistant materials like stainless steel and fluoroplastic, suitable for handling all kinds of corrosive media. Paired with mechanical seals, these pumps have good leak-proof performance, can handle both high and low temperature conditions, are easy to assemble and disassemble, have a long service life, and are simple to operate and maintain.

Ⅳ. Key Points and Precautions for Selecting Chemical Centrifugal Pumps
1. First, check the characteristics of the medium the chemical centrifugal pump will transport:
Confirm the liquid's acidity or alkalinity, temperature, viscosity, presence of solid particles, and whether it is toxic, flammable, or explosive. Use this information to select anti-corrosion materials for the pump body, impeller, and sealing components.
2. Calculate flow rate and head parameters:
When selecting the flow rate, leave a 10%-15% margin. The head should include the liquid lift height, pipe elbows, valves, and other pipeline resistance losses, with a 5%-10% margin reserved. This ensures the actual delivery performance of the chemical centrifugal pump and avoids insufficient performance during operating fluctuations.
3. Check Net Positive Suction Head (NPSH):
Ensure that the NPSH available on site is greater than the NPSH required by the pump itself. Pay special attention to high-temperature or highly volatile media to prevent pump cavitation damage.
4. Determine the installation type of the chemical centrifugal pump:
If there is ample space for maintenance on the ground, a horizontal pump is preferred; for tight installation spaces or pump installation above a pool, choose a vertical pump; for locations without external power or temporary operations, a mobile diesel chemical pump unit can be selected.
5. Match the sealing solution to the working conditions:
For normally corrosive media, use a mechanical seal; for toxic or easily leaking media, use a magnetic leak-free seal. For flammable and explosive conditions, use an explosion-proof motor.
 
Ⅴ. Chemical Centrifugal Pump FAQ
1. Can a chemical centrifugal pump transport clean water?
Yes, but for clean water, using a regular clean water pump is more cost-effective.
2. Why won’t the chemical centrifugal pump discharge water when starting?
It’s usually because air inside the pump hasn’t been fully expelled, causing air binding.
3. Can a chemical centrifugal pump transport liquid with particles?
It can transport a small amount of fine particles; if there are many particles, a wear-resistant model should be chosen.
4. How to choose between horizontal and vertical chemical centrifugal pumps?
Choose horizontal for easy maintenance, vertical for limited space.
5. How to fix strong vibration during chemical centrifugal pump operation?
Tighten the base bolts and check the impeller wear and piping situation.
6. Can a chemical centrifugal pump with slight water leakage from the seal still be used?
For corrosive media, it is recommended to stop the pump immediately for maintenance to avoid potential issues.
7. Should the chemical centrifugal pump be drained in winter?
If the temperature is below freezing, it must be drained to prevent the pump body from cracking.
8. Can a chemical centrifugal pump transport high-temperature liquids?
Determine based on the model parameters; high-temperature conditions require special accessories.
