GENERAL DESCRIPTION
The carbonator motor mounting uses a circular clamp,
similar to a hose clamp, as means of attaching the pump to a
specially machined hub on the motor. This concept was first
developed for the vending machine industry to pump carbonated beverages in soft drink dispensers. The main advantages are compactness and economy due to the elimination
of the adapter casting.
The rotary gear pump features an all bronze design
and 303 stainless steel shafts with options of non-metallic
gears and a variety of shaft seals. The built-in relief valve is
available in two options; internal recirculation to suction side
or external connection for return line to supply tank.
SUCTION LIFT
For a first start-up, the pump should be primed to avoid
dry running. Gear pumps are self-priming, but a foot valve
with strainer is recommended at the beginning of the suction
line. This will keep the gear chamber primed to insure instant
flow when the pump is started. maximum suction lift is 20
feet. The suction line should be as short as possible.

LIQUIDS AND TEMPERATURE
Bronze pumps are suitable for water, oil, and mild chemicals
in the pH-range from 4-10. Viscous liquids may be handled with
carbonator pumps up to a viscosity of 300 SSU. Higher viscosities
require a pump speed lower than 1725 RPM, which is currently not
available in carbonator motors.
Liquids containing abrasives, solids, powders or pigments
are highly detrimental to pump life and must be avoided. The recommended liquid temperature range is from 32oF to 140oF. If more
extreme temperature conditions exist, factory should be consulted.
Allowing the liquid to freeze in the pump can cause damage.
ROTATION AND RELIEF VALVE
The relief valve is not intended to be a metering or flow control device. Its main purpose is to function as a discharge pressure
relief when the spring tension is exceeded by the discharge pressure. Overheating can occur within 5-10 minutes if the discharge
line is completely shut off for extended periods.
Unless otherwise specified, the pump motor unit is supplied
by the factory for shaft rotation clockwise from shaft end. Reversing
the motor rotation will reverse the “in” and “out” ports and also
requires changing the relief valve location. The relief valve is
always on the discharge side in this pump series. The factory pressure setting is 50 PSIG. To increase pressure, turn the relief valve
adjusting screw in a clockwise direction.
To reverse single phase motors, find instructions on the
inside of the junction box cover or on the name plate of the motor.
