TLGLF Sliding Vane Pumps

Blackmer® TLGLF3 and TLGLF4 truck propane pumps, part of the Cavitation Line of sliding vane pumps, are designed to flange mount directly to a commercial internal control valve, in combination with the tank of a propane bobtail or LPG transport truck, and are ideal for LPG, propane, butane and anhydrous ammonia applications. Direct mounting of the propane transfer pump eliminates the need for inlet pipes, shut-off valve and external strainer, which can restrict flow and cause vaporization problems. The result is smoother operation and longer pump life.

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
  • Equipped with a double-ended drive shaft for clockwise or counterclockwise rotation by simply changing position of pump
  • Contains auxiliary intake port which can be used for emergency unloading of another tank or transport
  • 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
  • Internal 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
Application
  • Direct mounted, mobile installations found on:
    • Bobtail trucks
    • Transport trucks
    • LPG
    • Butane
    • Anhydrous ammonia
