- Ensure product is available at the inlet before starting the pump. This is
very important for pumps installed with un-flushed product seals, as these
sealing arrangements must never be allowed to run dry.
-
Before beginning operation, it is considered a good practice to
momentarily start/stop the pump to check the direction of rotation and
ensure that the pump is free of obstructions. Once this has been carried
out, begin operation keeping a visual check on suction and discharge
pressure gauges and monitor pump temperature and power absorbed
where possible.

Shutdown Procedure.
When shutting the pump down, stop the pump, close both the suction and
discharge valves and ensure that the necessary safety precautions are taken:
- The prime mover power source has been isolated.
-
If installed, flushed product seal auxiliary services have been isolated and
depressurised.
- Pump head and piping have been drained and purged.
3.6 Routine Maintenance – Non Atex units.
Grease

Oil
-
Check oil levels regularly.
-
Change the oil every 12 months or 3000 operating hours, whichever is
the sooner.

Seal Replacement Interval:
It is recommended that the Rotor Retainer O-ring seal is replaced every 12
months to maintain a bacteria-tight seal.
Rotor Retainer Seal Inspection:
Periodically inspect the Rotor Retainer O-ring seal for any discolouration,
nicks, or cracks. If any of the defects above are noticed, the O-ring seal must
be replaced. Inspection and replacement refer to the seal replacement
