The Blackmer RC40 LPG Regenerative Turbine Pump is a specialized high-performance solution designed for the transfer of LPG (liquefied petroleum gas), Autogas, propane, and butane in a variety of demanding applications.

  • Flow Rate:

    • 53 GPM (200 L/min)
  • Differential Pressure:

    • Up to 203 psi (14 bar)
  • Inlet Port:

    • 1-1/2" NPT (Flanged options: 1-1/2" ANSI Class 300 and DN40 DIN PN40)
  • Outlet Port:

    • 1" NPT (Flanged options: 1" ANSI Class 300 and DN25 DIN PN40)
  • Efficient Performance:

    • The pump features a regenerative turbine impeller design, ensuring high hydraulic efficiency and enabling it to generate high differential pressures at low flow rates, ideal for Autogas and LPG applications.
  • Cavitation Mitigation:

    • A design that facilitates the gradual collapse of vapor bubbles, effectively reducing the harmful effects of cavitation and enhancing the pump's longevity.
  • Self-Priming and Vapor-Handling:

    • Exceptional self-priming capabilities.
    • Handles vapors efficiently, especially when paired with an RV Series bypass valve.
  • Quiet and Vibration-Free Operation:

    • Operates without vibration or noise, ensuring smooth and reliable performance in diverse conditions.
  • Pulsation-Free Discharge:

    • Delivers a smooth fluid discharge, contributing to the durability of the overall pump system.
  • Durability and Versatility:

    • Rated for a maximum allowable working pressure of 34 bar (493 psi).
    • Suitable for liquids with high vapor pressures.
  • Service and Maintenance:

    • Designed for field repair, offering ease of maintenance and reduced downtime.
  • Autogas Dispensing:

    • Can support up to four hose dispensing systems for driveway Autogas stations.
  • Transfer and Industrial Uses:

    • Suitable for industrial LPG transfer and dispensing.
  • Marine Operations:

    • Facilitates LPG dispensing in marine environments.
  • Cylinder Filling:

    • Ideal for refilling LPG cylinders.
  • Forklift Refueling:

    • Enables quick and efficient LPG refueling for forklifts.
