- Ensure product is available in the tank before starting pump. This is very
important for pumps installed with unflushed product seals, as these
sealing arrangements must never be allowed to run dry.
- Before beginning operation it is considered 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.
3.5 Shutdown Procedure.
When shutting the pump down 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.
- RTP
TM
pumps are shipped fully lubricated with a lithium based extreme
pressure lubricant suitable for sealed for life units.
- For lubricant capacities refer to section 5.3.
3.7 Heating and Cooling Devices
see fig 8.
The RTP
TM
model can be supplied with a jacketed front cover and rotorcase
with ports for circulation of a heating/cooling media. The jacketed front cover
and rotorcase heating and cooling ports are strategically positioned such that
the required thermal effect acts on the pumping chamber and product seal
area.
The pressure rating of the RTP
TM
jacketed front cover and rotorcase
heating/cooling ports is 3.5 bar g (50 psi) and should not be exceeded without
consulting JPUK or your local JPUK distributor.
Heating/cooling of the pump head is used to maintain, rather than
increase/decrease the temperature of the pumped media and should be used
as part of a complete system where suction and discharge lines and vessels
are also heated/cooled.
