An installment to their Series B Chemical Metering Pumps, LMI has delivered their model B71. The B71 features a a switch conversion to external control for automatic systems, in addition to a manually adjustable stroke speed from 1 to 100 strokes per minute and a manually adjustable stroke length. It is precisely crafted for a 1.6 GPH (6.1 l/h) maximum capacity and and a maximum pressure of 150 PSIG (10.30 Bar).

*Minimum output is based on 1 stroke per minute and 10% stroke setting, minimum output can be reduced further in external mode. B9 pumps may be programmed for strokes per hour for lower outputs.

3FV indicates that the pump is equipped with an LMI Three Function Valve (pressure relief, priming aid, line drain).
4FV indicates that the pump is equipped with an LMI Four Function Valve. This diaphragm type, anti-syphon/pressure relief valve is installed on the pump head. It provides anti-syphon protection and aids in priming, even under pressure.
AUTOPRIME Liquid Ends AUTOPRIME liquid ends are used in applications with off-gassing liquids such as Sodium Hypochlorite | ||||||

AUTOPRIME liquid ends have 3 check valves: Suction on the bottom; Discharge on the front; Autoprime bleed on the top. By design, a repeatable portion of the process fluid continuously bleeds through the top check valve to be returned to the chemical supply. The result is the assurance that any gas in the head is automatically relieved thus eliminating air-binding. Depending on application, output may be reduced up to 50%. Variables include supplier piping, stroke length and speed setting. The maximum output per the tables above is reduced to account for the continuous bleed.
