LMI Series B1 HI chlorine metering pumps are designed for accurate and trouble free chlorine injection. 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.

The LMI Auto-Degassing LMI Series B1 chlorine metering pumps have two control dials - one for manual stroke and one for speed adjustments. The clear LMI see-thru acrylic pump head provides a clear view of the diaphragm operation and chemical flow through the pump.

LMI Series B1 sodium hypochlorite feed pumps come complete with instructions, foot valve, ceramic weight, injection valve, four function discharge valve and chemical tubing. Pumps are 120VAC. LMI Series B1 chemical dosing pumps are NSF & cUL approved.
