The range of TLGLF pumps from Blackmer are flange mounted directly to commercial internal control valves, eliminating the need for inlet pipes, shutoff valves and external strainers which can restrict flow and cause vaporization problems.

Capacities of the TLGLF3 pump range from 60 to 129 US gpm (227 to 488 lpm) with a 3 in ANSI intake flange. The TLGLF4 pump powers 200 to 350 US gpm (757 to 1,325 lpm), with a 4 in ANSI intake flange. The maximum differential pressure for both flange-mounted pumps is 125 psi (8.62 Bar).

Both the TLGLF3 and the TLGLF4 pumps are equipped with a double-ended drive shaft for clockwise or counterclockwise rotation by simply changing the pump position. Each flange-mounted pump in the TLGLF range from Blackmer provides an auxiliary intake port which can be used for emergency unloading of another tank or transport.
