Description
LGLD2-4 Sliding Vane Pumps
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.
Blackmer fully Integrated Unit Assemblies are the pre-engineered and pre-designed drop-in pumping solution. These unit assemblies, include motor, gearbox, baseplate, coupling safety covers, and a LGL Sliding Vane Pump (2, 3 & 4-inch size). No alignment required with these pre-configured fully Integrated Unit Assemblies as they are ready for immediate drop-in installation.
