Siemens Chem-Ad Series - Manual (Page 2)

Description
The Chem-Ad Series A model 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 level and its enclosure, IP65, the Chem-
Ad Series A 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.
