LMI is delivering their model B74 as part of the Series B Chemical Metering Pump. The B74 has a 7.0 GPH (26.5 l/H) maximum capacity and a maximum pressure of 30 PSIG (2.07 Bar). Both the stroke speed and length are manually adjustable, along with a switch conversion feature to external control for automatic systems.

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.
* - These liquid ends use 3/8 diameter valve balls. Pump output may be reduced in some applications.
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.
