Wallace & Tiernan® Liquid Feed Systems Chem-Ad® Series A Metering Pump

The Chem-Ad® Series A electronically controlled, motor driven diaphragm metering pump 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 Diaphragm pumps 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 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.

DescriptionThe Chem-Ad® Series A diaphragm metering pump features manual control, or optional external control, and is designed to handle multi-phase solutions that tend to out-gas.

Due to its unique design incorporating pre-feeding and a gasket-free ceramic piston/cylinder unit the pump can maintain a high reproducibility even when handling very low feed rates at maximum stroke frequency.

Its smooth pulsation characteristics ensure high metering accuracy and long life of diaphragms and valves. Due to its unparalleled low noise and its enclosure, IP65 (NEMA 4X), the Chem-Ad® Series A pump is perfectly suitable for laboratories and humid ambient conditions.

The basic model has an on/off switch, a level switch input, and alarm output connection. The standard liquid end made of PVDF ensures a wide range of chemical resistance.

ControlsManual - E11Manual control is on-line by means of a mechanical stroke length adjustment via a two-turn knob graduated 0 to 100%. An on/off switch is also provided. There are connections to accept level input and alarm output.

Automatic - E60 (XL Model)The automatic E60 (XL Model) includes:An integrated LED display panel for easy to read,

clear indication of operating status and user-friendly programming.

A four key membrane touch pad simplifies function selection.

Local or remote control via analog (0/4-20mA or 20-4/0mA or pulse input signals.

Signal scaling allows for multiplication or division of the pulse input signal.

Flow/no flow verification via an optional flow monitor.

Automatic - E60Plus (XL Model)With the addition of an intelligent control package (ICP) and Oval Gear Meter (OGM), the E60 becomes the full featured E60Plus

and includes:Set point controls with automatic frequency compensation

for constant chemical feed.Chemical consumption data logging.Real time feed rate display.Plug and play with calibration data storage on OGM.Adjustable flow alarm points.

Spares and AccessoriesLiquid End PM Kit® PackagesFor every model of the Chem-Ad® Series A metering pump, a corresponding maintenance kit is available. This economically priced package contains all spare and wear parts for a prompt and quick maintenance of the liquid end.

Suction LanceThis option includes pre-wired, built-in-low and empty level switches, foot valve and strainer. This option is recommended with the Series A pump.
