Ebsray regenerative turbine pumps

Ebsray regenerative turbine pumps are specifically designed for the transfer of low-viscosity and easily vaporizing liquids, such as LPG, propane, butane, DME, CO₂, and ammonia. These pumps are ideally suited for high-pressure applications where significant pressure differentials are required even at low flow rates. Within the circulation pressure range, Ebsray pumps are a standard product, particularly in autogas and industrial applications.

Operating Principle

A regenerative turbine pump operates with a rotating, non-contact impeller that features multiple small cells (approximately 60 units) along its edge. The liquid enters the pump’s suction port, where the impeller accelerates it within the hydraulic channel. The liquid circulates through the channel multiple times, incrementally increasing its energy and pressure. This enables the formation of a high-pressure differential—hence the name regenerative turbine pump.

Applications

• Transfer and refuelling of autogas (LPG, propane, butane)
• Industrial gas applications
• DME, CO₂, ammonia, and other low-viscosity, easily vaporizing liquids
• Bottling, distribution, terminals, and storage tanks
• Marine and shipbuilding industries

Advantages

• Cavitation-Free Performance: The pumps maintain efficiency even with vapor-laden liquids and those near their boiling point, preventing damage from cavitation and pulsation.
• High Pressure, Low Flow: Especially suitable for applications requiring high pressure at low flow rates.
• Quiet and Vibration-Free Operation: The design ensures nearly silent and vibrationless operation.
• Easy Maintenance: Compact construction, few moving and wearing parts, and simple servicing.
• Long Service Life: Minimal wear and high reliability.
• Certifications: CE marking, ATEX compliance, UL51, AS1596.

Technical Data

• Temperature range: down to –40 °C
• Installation: IEC/NEMA flange mounting, multiple port options (NPT, ANSI, DIN)

Accessories and Recommendations

• Bypass valves (BV models) protect the pump and system from overpressure.
• Always check chemical compatibility with the manufacturer for the intended application.
