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.
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.
