Regenerative Turbine Pumps

Ebsray® regenerative turbine pumps have been designed for low-flow, high-head duties with low-viscosity liquids, such as LPG, propane, Autogas and butane. These turbine pumps, which are available in two series – R and RX (submersible regenerative turbine pumps) – offer exceptional performance and reliability even under extremely low NPSH operating conditions, and possess the ability to handle entrained vapors without due loss of efficiency or internal damage. Ebsray regenerative turbine pumps are CE marked and ATEX-compliant, and suitable for underground, aboveground and submersible LPG- and Autogas-pumping applications.

The regenerative turbine pump is a rotodynamic pump (as opposed to a positive displacement (PD) pump), and as such sits alongside the centrifugal family of pumps. It operates using an impeller that is a rotating, non-contacting, free-wheeling disc that has many small buckets or cells (typically about 60) on its periphery. When liquid enters the suction port of the turbine pump it is picked up by the impeller and instantly accelerated around in the narrow hydraulic channel (casing volute) surrounding the cells. The spiraling – or ‘winding-up’ – of the liquid many times (at sonic speeds) within the one revolution incrementally builds energy/pressure. This ‘winding-up’ of the numerous small liquid cells creates the differential pressure capability of the pump – hence the name regenerative turbine pump. Regenerative Turbine Pumps are also known as turbine pumps, peripheral pumps, centrifugal regenerative pumps, regenerative pumps and many other names.

The regenerative turbine pump design is very unique and works on a different principle than PD pumps. They are ideal for handling clean liquids at or near their boiling point e.g., LPG, CO2, hot water (boiler feed).
