The Wallace & Tiernan Chem-Ad Series A is an electronically controlled, motor driven diaphragm metering pump. It is designed specifically for very low feedrate applications, particularly sodium hypochlorite. The pump features a unique, constant circulation liquid end with a calibrated, adjustable plunger for precise feedrate control. This design ensures consistent performance, even with chemicals that tend to outgas, such as hypochlorite.
The Chem-Ad series of diaphragm metering pumps provided by Siemens Water Technologies are designed to handle the most demanding applications in the treatment of potable water, swimming pools, wastewater and industrial processes. A well-balanced range of capacities combines with excellent reproducibility and optimal chemical resistance. Chem-Ad metering pumps are of the positive displacement-type driven by proven overload-proof motors. Since they are available with a wide choice of configurations ranging from manual to flow proportional to setpoint, these pumps can cover any metering requirement.
The XL Series, shown below, features an integrated LED display panel, touch-pad controls and multiple control functions, including feedrate setpoint with closed-loop control, flow/no-flow monitoring, batch operation and feedrate display.
