MAGNUM 620D PUMP OPERATION / MAINTENANCE MANUAL
3 START-UP
•
Pump air supply pressure must be regulated. (See
Error! Reference source

.)
•
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.
