Autogas Sliding Vane Pumps Ductile-Iron High-Pressure LPG and NH3 Pumps

Blackmer® has several options for sliding vane pumps that are suitable for the rigors associated with Autogas applications. Part of the Cavitation Line, LGL156, LGL158 and LGLH2 sliding vane pumps feature high differential pressure designs and a cavitation suppression liner, providing a fast and quiet operation that performs consistently and without fail. Replaceable liners and discs also ensure that downtime is kept to a minimum.

Features and Benefits

  • Pumps are listed by Underwriters Laboratory for both LPG and anhydrous ammonia (NH3) service
  • Cavitation suppression liner design for reducing the noise, vibration, and wear normally caused by entrained vapors
  • Replaceable casing, liners and end discs allow easy rebuilding of the pumping chamber to like-new condition
  • Ductile-iron construction with internal relief valve
  • Durable pumps for fast and quiet operation, providing sustained performance and trouble-free operation
  • Blackmer mechanical seal and ball bearing construction provide maximum reliability
  • Symmetrical bearing support assures even loading and wear for long life
  • Relief valve protects pump against excessive pressures
  • External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
  • Advantages of sliding vane technology:
    • Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
    • Excellent self-priming and dry-run capabilities
    • Sliding vane design provides sustained performance and trouble-free operation
    • Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
    • High suction lift and line-stripping capabilities
    • Low maintenance and low life-cycle costs
