type of chlorinator, make sure that you follow the

Hypochlorinators are solution chemical feeders
that introduce chlorine into the water supply as
hypochlorite solution. They are usually modified
positive displacement piston or diaphragm mechanical
pumps. However, hydraulic displacement
Hypochlorinators are also used. Fully automatic types
are actuated by the pressure differentials produced by
orifices, venturis, valves, meters, or similar devices.
Hypochlorinators are sometimes used as standby
equipment for gas chlorinators. Portable equipment is
also available which may be used for main disinfection
or during emergencies. Hypochlorinators can also be
used to feed chemicals for scale and corrosion control.
Of course, you may have to use various types of
Hypochlorinators. As part of this discussion on
chlorination equipment, a brief treatment is given on
additional types of Hypochlorinators of interest to the
The Proportioneers Chlor-O-Feeder is a positive
displacement diaphragm-type pump with an
electrically driven or hydraulically operated head. The
electrically driven Proportioneers Chlor-O-Feeder is
shown in figure 7-9. The capacity of the most popular
type, the heavy-duty Midget Chlor-O-Feeder, is 95
gallons of solution in 24 hours.
The motor-driven type of hypochlorinator may be
