The LMI Series B9 programmable electronic chlorine metering pumps feature a LCD display and 4-key tactile keypad. In Auto mode, these pump are externally controllable by means of 4-20 mA signal, which will automatically increase or decrease pump speed as called for by the plant SCADA system.

The clear LMI see-thru acrylic pump head provides a clear view of the diaphragm operation and chemical flow through the pump. These pumps will pump all water treatment chemicals, but are specially designed to handle off gassing chemicals such as chlorine that can cause air locking. The additional valve on the pump head automatically returns a small amount of chemical and chemical gas to the solution tank with each pump stroke.

LMI Liquipro Series B9 chemical feed pumps come complete with instructions, foot valve, ceramic weight, injection valve, four function discharge valve and chemical tubing. Pumps are 120VAC. LMI Liquipro Series B9 chemical dosing pumps are NSF & cUL approved.
