What are centrifugal pumps used for?
Centrifugal pumps use a rotating impeller to move liquids and are commonly used for water transfer, circulation and industrial processes.
How do I choose a centrifugal pump?
Compare the required flow rate, total head, liquid characteristics and electrical supply with each pump’s performance curve.
Are centrifugal pumps suitable for dirty water?
Some are designed for clean water only, while others handle solids or wastewater. Check the particular pump’s permitted liquid and solids specification.
