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.

Start slowly with air regulator at low (> 25 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: Specification to be used to size regulators and control valves.
