5 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.
