5 Great Reasons Why You Should Choose A Multistage Centrifugal Pump A multistage centrifugal pump is a type of pump that features two or more impellers stacked together on the same shaft with a shared motor, as if connected in a series. Each impeller and volute (or stage) that the water flows through will boost the pressure of the water, so the more impellers and the more stages, the greater the pressure discharged. No matter how many impellers you add, the flow is constant; should flow change then you'll need a variable frequency drive. The multistage centrifugal pump's high pressure: flow ratio is useful for applications that require high pressure to get a small amount of liquid. For example, when you need to pump water up to reach the top apartment in a tall block of flats. Advantages of multistage pumps Multistage pumps are very efficient as they have several smaller impellers to allow smaller tolerances. With just one motor and one shaft, every impeller added has minimal energy loss for each increase in stages. There will also be lower noise levels at each additional stage than that of a single stage pump. In general, any application that requires high output or high pressure would benefit from a multistage pump, whether horizontal or vertical. When choosing between setting up multiple centrifugal pumps in a series or installing a multistage pump, there are five great reasons why you should choose a multistage centrifugal pump: 1. Greater efficiencies 2. Less space 3. Higher pressure 4. Lower head for each volute or stage 5. Cost savings So, should you attempt to generate more head with a series
of single-stage pumps or choose a multi-stage centrifugal pump?
