Published Blackmer-related specifications confirm the TLGLF3C as a 3-inch flange-mounted truck pump with a 125-PSI maximum differential pressure and 350-PSI maximum working pressure.
The Blackmer TLGLF3C is a heavy-duty 3-inch flange-mounted sliding-vane truck pump engineered for mobile liquefied-gas transfer applications. It is particularly suited to propane bobtail and transport-truck installations where dependable flow, compact direct mounting, and reliable operation are important.
Unlike a conventional base-mounted transfer pump, the TLGLF3C is designed to mount directly to a commercial internal control valve and cargo tank. This arrangement can eliminate restrictive inlet piping and associated fittings between the tank and pump, helping reduce inlet losses and vaporization. Blackmer’s installation documentation specifically identifies direct mounting to bobtail or transport tanks as the intended configuration.
The pump incorporates Blackmer’s sliding-vane pumping principle and a double-ended drive shaft, allowing the unit to accommodate clockwise or counterclockwise PTO arrangements through installation orientation. An auxiliary intake connection also permits applications such as emergency unloading of another tank or transport.
Blackmer lists the TLGLF platform for LPG and anhydrous-ammonia service, while distributor specifications identify the TLGLF3C at up to approximately 140 GPM.
This pump is suitable for professional liquid-transfer systems including:
A commercial bobtail builder specifically lists the Blackmer TLGLF3C 3″ flanged pump as equipment used on an MC331 propane cargo-tank configuration.
