Single Stage Centrifugal Pumps & Centrifugal Water Pumps

Single stage centrifugal pumps are the most common pump for fluid transfer in high flow rate, low pressure installations. If a lower flow rate or a higher pressure is needed over what a single stage centrifugal pump can provide, a multistage centrifugal pump is a better suited alternative. Centrifugal water pumps are common single stage pumps, however due to the wide range of materials
