START-UP

Pump air supply pressure must be regulated. (See Figure 3-2: Pressure vs. Fluid
Temperature Chart.)

Open the fluid suction (IN) line valve, if necessary.

Open the fluid discharge (OUT) line valve, if necessary.

Program external control to desired settings

Start slowly with air regulator at low (> 20 psi) pressure setting. Increase pressure to
attain desired flow, up to the maximum rating (See Section 3.1).

Refer to Troubleshooting, Section 5, if pump fails to start.
ATTENTION: Prolonged periods (> 5 minutes) of dry running 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.
3.1 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.
NOTE: The following chart is for specification to be used to size system.
