MAXIM 50E/U PUMP OPERATION / MAINTENANCE MANUAL PAGE 9
3 START-UP

Pump air supply pressure should be regulated. (See : Pressure vs. Fluid
Temperature Chart)

Open the fluid suction (IN) line valve, if necessary.

Open the fluid discharge (OUT) line valve, if necessary.

Start with air regulator at low (> 20 psi) pressure setting. Increase pressure
to attain desired flow, up to the maximum rating (See Section 3.1).

Table 1: Consumption / Efficiency can be used to determine approximate air
consumption.

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 a compatible enclosure.
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.
