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.
