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. Increase or decrease setting
to attain desired flow, up to 80 psig (4.1 bar). Minimum is 20 psig.
•
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 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
specific gravity and viscosity.
