Peripheral Vane / Regenerative Turbine Pump

What is a Peripheral Vane / Regenerative Turbine Pump

A regenerative turbine pump is similar to a centrifugal pump, except it operates with a different style impeller. A standard centrifugal impeller has curved vanes that extend from the centre to the edge of the impeller. The regenerative turbine impeller has rows of vanes on each side of the impellers rim. On the suction side liquid is gathered by the impellers vanes, after making only one revolution in the annular channel, the fluid has a high-velocity that sends the liquid out the discharge. Liquid entering a centrifugal pumps impeller can pass between the vanes only once. Energy is added to the liquid as it travels from the centre of the impeller to the rim. In a regenerative turbine pump liquid recirculates between the impellers vanes. This helical action carries the liquid forward, energy is added to the liquid in a number of impulses by the impellers vanes as it travels from suction to discharge as a liquid builds pressure.

For low flow high head applications regenerative turbine pumps offer better efficiency than centrifugal pumps and can develop several times the discharge pressure of a centrifugal pump having an equally sized impeller.

The regenerative turbine impeller can pump fluid with up to 40% entrained gases without damage from cavitation or any performance loss. Centrifugal pumps are not designed to handle gas in a liquid, gas in a centrifugal pump can create a significant loss in performance causing fluctuating flow, discharge pressure, and unnecessary wear and vibration of the centrifugal pumps internal components. This makes a regenerative turbine pump a great solution with cavitation is a concern.
