MEGA 120E PUMP OPERATION / MAINTENANCE MANUAL

3 START-UP
•
Pump air supply pressure should be regulated.
•
Open the fluid suction (IN) line valve, if necessary.
•
Open the fluid discharge (OUT) line valve, if necessary.
•
Start with air regulator at low pressure setting (<15 psig). Increase or
decrease air pressure to attain desired flow, up to 80 psig (0.55 MPa).
•
Refer to Troubleshooting, Section 5, if pump fails to start.
ATTENTION:
Prolonged periods of dry running (>5 minutes) will damage critical internal
pump parts.
CAUTION:
When handling potentially dangerous fluids under pressure, the
pump and its fittings should be placed in an enclosure.
3.1 HIGH TEMPERATURE OPERATION
Pump operation at temperatures above 60°C requires periodic tightening of the tie bolt
nuts. The frequency of this procedure is best established by the user.
3.2 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 properties. The
following data was taken using water at atmospheric temperature and pressure with
limited sample sizes. The data is intended to aid in system design and should be used
for general reference only.
