As part of the Cavitation Line of sliding vane pumps, these LGLD propane pumps are ideal for propane, LPG, butane and anhydrous ammonia applications including bulk plant service, multiple cylinder filling applications, vaporizers, bobtails and transports. All LGLD propane pump models have an internal relief valve, and a replaceable casing liner and end discs for easy rebuilding of the pumping chamber if ever necessary. In addition, these pumps feature cavitation suppression liners to reduce noise, vibration and wear.
Blackmer® LGLD2 propane pumps are often mounted to the chassis of a bobtail, or to a steel pad that is welded to the tank. The 3- and 4-in rotary vane pump models can be mounted to a transport in a number of different ways, generally near or between the tank landing gear brackets.
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
LGLD2 and LGLD3 models have double-ended drive shaft arrangement, popular for bobtail service
Blackmer mechanical seal and ball bearing construction provide maximum reliability
Symmetrical bearing support assures even loading and wear for long life
Capable of being mounted to a truck or chassis of a bobtail, or to a steel pad welded to the tank.
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
