Intended for close-coupled mounting to NEMA 48 Carbonator Mount footed motors using clamp and T coupling. Pump can be mounted in any orientation relative to the motor base. For vertical installations, mount pump below motor. Complete pump / motor units are available.
LIQUIDS & TEMPERATURES
For use with particulate free and non-abrasive fluids compatible with bronze and stainless steel. Suitable for oils and other lubricating fluids and for intermittent duty when handling water based fluids in the 4-10 pH range. Temperature range: -40° F to 225° F.
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.

ROTATION AND RELIEF VALVE
The relief valve is not intended to be a metering or flow control device. Its main purpose is to functionas 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.
