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.
