The pump construction of the Positronic IV, primarily Teflon
and polypropylene, is capable of handling corrosive fluids. It
has the capability to 55 psig (3.8 bar) discharge pressure.
Minimum flow rate is 15 oz/min (445cc/min.) (when using a
metering orifice,
refer to Section 11, page 12
) and a maximum
of 1.2 gal/min (4540 cc/min). As product viscosity increases
from that of water and/or suction lift increases from zero feet
to a maximum of 3-1/2 ft (107 cm), maximum flow rate will be
less than 1.2 gal/min (4540 cc/min).
Operating sequence of the system begins when an electric
signal (i.e., timer or conductivity sensor) entering the pneu-
matic controller energizes a solenoid to open an air valve
allowing regulated air pressure to power the pneumatic pump.
The solenoid requires 110/120 VAC, 50/60 Hz single phase
electricity. The compressed air entering the Pneumatic Con-
troller must be filtered to 5 microns. No air lubricator is to be
used.
Each pump consumes a maximum of 3 scfm (1.4dm
3
/s) at the
maximum air pressure of 70 psig (4.8 bars). Pump delivery is
controlled by the air pressure setting of a regulator.
Components of the Positronic IV system consist of a pneu-
matic controller and an air operated double diaphragm pump.
Required accessories include a foot valve, anti-siphon valve
and a check valve.
1.0 PREFACE
It is imperative that all personnel concerned with the system
installation, operation and maintenance become familiar with
this manual. For a clean and functional installation, these
general instructions will provide the necessary guidance.
Understanding this information will also help you make instal-
lation modifications to meet the varying conditions and sur-
roundings.
WARNING: These installation and servicing instruc-
tions are for use by qualified personnel only. The
installation must be in accordance with local plumb-
ing and electrical codes.
