LGLD2-4 Sliding Vane PumpsDuctile-Iron Multi-Purpose Pumps for Bulk Plants, Terminals and Truck Systems

As part of the Cavitation Line of sliding vane pumps, these LGLD pumps are ideal for applications including bulk plant service, multiple cylinder filling applications, vaporizers, bobtails and transports. All 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 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 models can be mounted to a transport in a number of different ways, generally near or between the tank landing gear brackets.

Blackmer offers a full line of liquefied gas pumps and
oil-free gas compressors, designed for maximum performance and reliability. From the smallest cylinder filling operation to
the largest, most sophisticated bulk plant/rail car unloading system, you will find Blackmer pumps and compressors operating throughout the world.

Sliding vane design is ideal for butane, propane, anhydrous ammonia, propellants, refrigerants and similar liquefied gases

Blackmer liquefied gas pumps are widely used for cylinder filling, motor fueling, bulk transfer, vaporizers, and on bobtails and transports.

Utilizing Blackmer’s unique sliding vane design, these positive displacement pumps offer the best combined characteristics of sustained high-level performance, energy efficiency, trouble- free operation, and low maintenance cost.

Pump models are available in 1 to 4-inch port sizes.
All models have ductile iron construction for thermal shock resistance, low friction ball bearings for high efficiency and quiet operation, and threaded lockcollars that prevent end thrust wear

LGLD2, LGLD3 & LGLD4 Pumps

Multi-Purpose Pumps for Bulk Plants, Terminals and Truck Systems

These rugged pumps are ideal for bulk plant service, multiple cylinder filling applications, vaporizers, bobtails and transports.

Single- or double-ended drive shaft models are offered in 2-, 3- and 4-inch port sizes with capacities ranging from 30 to 350 U.S. gpm (114–1,325 L/min). The LGLD2 and LGLD3 models have long been popular for bobtail service because of their double-ended drive shaft arrangement, which allows the pump to be easily positioned for clockwise or counter- clockwise shaft rotation.

All 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.

Standard construction materials include Buna-N mechanical seals and Duravanes for handling both LP-gas and anhydrous ammonia.

Maximum differential pressure for the 2- and 3-inch models is 150 psi (10.34 Bar), and 125 psi (8.62 Bar) for the 4-inch models. Ports are offered with NPT tapped companion flanges or weld flanges.

Truck Mounted Drive

Blackmer LGLD2 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-inch models can be mounted to a transport in a number of different ways, generally near or between the tank landing gear brackets.

Truck mounted pumps are normally driven through a P.T.O. or hydraulic drive system. Refer to Blackmer’s Liquefied Gas Handbook-Bulletin 500-001 for various types of bobtail and transport pump systems.
