Centrifugal Pump

Centrifugal Water Pump

A centrifugal water pump uses a rotating impeller to move water into the pump and pressurize the discharge flow. Standard, trash, and submersible models are three different alternatives to centrifugal water pumps. All liquids can be pumped using centrifugal water pumps, even liquid with low viscosity. These pumps work great with thin liquids and high flow rates.

What Are the Advantages of Using Centrifugal Water Pumps?

Centrifugal pumps could present these 6 problems:

  1. Corrosion: Different fluid properties can corrode the pump
  2. Overheating: Some pump might need liquid recirculating to avoid overheating caused by low flows
  3. Prime: Centrifugal pumps must be filled with the fluid in order to operate properly
  4. Cavitation: The positive suction head of the system is too low for the selected pump
  5. Wear of the Impeller: Can be worsened by suspended solids
  6. Leakage: A long rotating shaft

When Can They Be Used?

Centrifugal pumps are used on these 6 applications, just to name a few:

  1. Buildings: To pump water supply, including pneumatic systems and in places where no suction lift is required.
  2. Boost Application: To boost pressure from the intake line.
  3. Wells: In domestic water supply systems
  4. Fire Protection System: To provide a continuous pressure source, but these water pumps should be in compliance with NFPA.
  5. Hot-Water Circulation: To move water in a closed system which requires low head.
  6. Sump Pits: Either vertical or horizontal water pumps. Units are operated by an automatic switch controlled by the float.
