The Blackmer RC20 LPG Regenerative Turbine Pump is designed for high-pressure transfer applications of LPG (Liquefied Petroleum Gas), Autogas, propane, and butane.

  • Flow Rate: 16 gpm (62 L/min)
  • Differential Pressure: 203 psi (14 bar)
  • Ports: DN 25/1 NPT(F) inlet and outlet ports
  • One Hose Dispensing for Autogas
  • Creative Impeller Design: Optimized for hydraulic performance, it can achieve high differential pressures even at low flow rates. This is critical for Autogas applications where consistent pressure is necessary.

  • Cavitation Mitigation: The pump minimizes cavitation effects by allowing for a gradual collapse of vapor bubbles. This helps protect the pump from potential damage caused by cavitation.

  • Self-Priming & Vapor Handling: It demonstrates superior self-priming and vapor-handling capabilities, ensuring consistent operation, especially when paired with an RV series bypass valve.

  • Vibration-Free Operation: The pump operates smoothly without generating vibration or noise, making it reliable across various pumping scenarios.

  • Smooth, Pulsation-Free Discharge: This feature ensures the longevity of the pump system by delivering a steady, pulsation-free fluid discharge.

  • High-Pressure Rating: The RC20 is rated for a maximum working pressure of 34 bar (493 psi), making it suitable for handling liquids with high vapor pressures.

  • Field Repairs: The pump is designed for ease of maintenance, allowing for field repairs when necessary.

  • Autogas Driveway Dispensing: Can support dispensing for up to four hoses for Autogas fueling at homes or service stations.
  • Transfer and Industrial Dispensing: Ideal for high-pressure liquid transfer and industrial dispensing needs.
  • Marine Dispensing: Suitable for refueling vessels and boats.
  • Cylinder Filling: Used for filling LPG cylinders.
  • Forklift Refueling: Provides refueling capabilities for forklifts running on LPG.
  • Direct Burner or Vaporizer Feed: Can feed liquid directly into a burner or vaporizer system.
  • Portable Tanks: Efficiently handles LPG transfer to portable tanks.
  • Above-ground and Underground Tanks: Can be used for dispensing and transferring LPG into both above-ground and underground storage tanks.
