START-UP
Open the fluid suction (IN) line valve, if necessary
Open the fluid discharge (OUT) line valve, if necessary
Pump air supply pressure should be regulated
Operate pump at 20 psig initially to prime pump
Increase pressure to attain desired flow, (not to exceed 80 psig)
If the pump fails to start, refer to the troubleshooting section or contact Trebor for
further assistance.
ATTENTION: Prolonged periods (>5 minutes) of running without fluid can damage critical
internal pump parts.
CAUTION: When handling potentially dangerous fluids under pressure, the pump
and its fittings should be placed in an enclosure away from operators.
5.1 PERFORMANCE CHARTS
Pumping capacity is a function of air supply pressure and volume, suction head, suction
line restrictions, discharge head, discharge line restriction, and fluid specific gravity and
viscosity.
