Blackmer RC40 LPG Regenerative Turbine Pump

For LPG and Autogas applications, Blackmer® provides the Americas market with Ebsray® Series regenerative turbine pumps.

The high-pressure transfer of LPG, Autogas, propane, and butane is the intended use for the Ebsray RC Series Regenerative Turbine Pumps. The creative impeller design, which maximizes hydraulic performance and produces high differential pressures even at low flow rates—an essential factor for Autogas applications—is the key to these pumps' success.

  • Mitigates the adverse impacts of cavitation by facilitating a gradual collapse of vapor bubbles, reducing potential damage.
  • Demonstrates outstanding self-priming and vapor-handling capabilities, particularly when utilized alongside an RV series bypass valve.
  • Functions without generating vibration or noise across various pumping scenarios.
  • Delivers a smooth, pulsation-free discharge of fluid, promoting overall pump system longevity.
  • With a maximum allowable working pressure of 34 bar (493 psi), it is well-equipped to handle liquids with high vapor pressures.
  • Field repairs are feasible, providing practical maintenance options.
  • Flow 53 gpm (200 L/min)
  • Differential Pressure 203 psi (14 bar))
  • Four Hose Dispensing for Autogas
