Operation

Before You Start the Pump

Read

and follow all instruction manuals, labels and tags supplied with this pump and with all the accesso ries you add to the system, before operating the sys tem.

Flush the Pump Before First Use

The

pump was tested in lightweight oil. If the oil will contaminate the fluid you are pumping, flush it out with a compatible solvent.

Packing Nut Tightness

The

packing nut (21) should be tight enough to stop leakage, but no tighter. Overtightening compresses and damages the packings, and may cause the pump to leak, reducing performance. See Fig. 4.
