As part of the Cavitation Line of sliding vane pumps, Blackmer® LGRL and LGL propane pumps are ideal for various liquid propane applications, including motor fueling, multiple-station cylinder filling and a variety of small transfer jobs. Available with 1.25- or 1.5-in NPT tapped ports, all of these lpg pump models feature an internal relief valve and a cavitation suppression liner that reduces noise, vibration and wear. These propane transfer pumps can be easily rebuilt to like new conditions, with its replaceable end disc, vanes, and cavitation suppression liner. These rotary vane pumps are ideal for motor fueling, multiple-station cylinder filling and a variety of small transfer jobs for all propane, lpg, butane, and anhydrous ammonia applications and are UL-Listed.
These sliding vane propane pumps are also available with a flanged mounting. Standard LGRLF1.25, LGLF1.25, and LGLF1.5 propane pump models are supplied with an integral bracket and a flexible shaft coupling, ready to accept a NEMA C-face or IEC flanged-face motors. All LGLF sliding vane pumps are available with or without electric motors.
Features and Benefits
Pumps are listed by Underwriters Laboratory for both LPG and anhydrous ammonia 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 provides greater resistance to both thermal and mechanical shock
Durable design provides fast and quiet operation with sustained performance and trouble free operation
Latest 6-vane design contributes to reduced noise levels in the pumps
All models have 1.25- or 1.5-in sized NPT tapped ports
Accepts standard C-face mounted motors
Internal relief valve protects pump against excessive pressures
Blackmer mechanical seals are specifically developed for non-lubricating liquids
Symmetrical bearing support assures even loading and wear for long life
Internal relief valve protects pump against excessive pressure buildup
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
