TLGLF Sliding Vane Pumps

Blackmer® TLGLF Sliding Vane Pumps are flanged mounted propane truck pumps. UL listed for propane, butane and anhydrous ammonia, these pumps come in three models: the 3-inch TLGLF3, the 3-inch TLGLF3HD, and the 4-inch TLGLF4. With a max flow rate of 425 gpm (1,608 L/min) the TLGLF4 pumps are designed for transport loading and unloading. Whereas the TLGLF3, designed for bobtail truck use, features a flow rate of 140 gpm (530 L/min) ideal for smaller tank vessel sizes. With an increased flow rate that is 55% greater than the TLGLF3, the TLGLF3HD model features flow rates of 180 gpm (681 L/min), ideal for high-capacity bobtail trucks that often have 7,000 gallon sized tank vessels.

All TLGLF pumps offer maximum differential pressure of 125 psi (8.62 bar) and can be driven by PTO shaft or by hydraulic motor using an adapter kit. Direct mounting of these propane truck pumps eliminates the need for inlet pipes, shut-off valve and external strainer, which can restrict flow and cause vaporization problems. The result is smoother operation and longer pump life. These propane pumps also feature cavitation suppression liners that reduce noise, vibration and wear caused by cavitation.
