If the above procedure is completed satisfactorily, the pump controls are operating correctly and
the vacuum pump operation is proved.
Select the RESET display on each pump controller and all fault conditions should be cancelled.
7.1.6
Quadruplex Pump System
Quadruplex systems have two Duty, one Standby, and one Reserve pump.
The location of Duty, Standby and Reserve pumps is rotated automatically to ensure equal usage
of all pumps.
Each pump is sized to provide 50% of the system design flow.
1. Switch on all isolators and allow the pumps to evacuate the vessels to the Duty cut-out of
650 mmHg.
2. Identify the Duty pumps and vent the vessels, via one manual drain, until the Duty pumps
start (there will be a delay between the two pumps starting to prevent overloading of the
electrical supply).
3. Isolate the Duty pumps and continue to vent the vessels until the Standby pump starts.
4. Isolate the Standby pump and continue to vent the vessels until the Reserve pump starts.
If the above procedure is completed satisfactorily the pump controls are operating correctly and
the vacuum pump operation is proved.
Select the RESET display on each pump controller and all fault conditions should be cancelled.
7.1.7
Pentaplex Pump System
Pentaplex systems have three Duty, one Standby, and one Reserve pump.
The location of Duty, Standby and Reserve pumps is rotated automatically to ensure equal usage
of all pumps.
Each pump is sized to provide 33% of the system design flow.
1. Switch on all the isolators and allow the pumps to evacuate the vessels to the Duty cut-
out of 650 mmHg.
2. Identify the Duty pumps and vent the vessels, via one manual drain, until the Duty pumps
start.
Note: There will be a delay between each of the pumps starting to prevent overloading of
the electrical supply.
3. Isolate the Duty pumps and continue to vent the vessels until the Standby pump starts.
4. Isolate the Standby pump and continue to vent the vessels until the Reserve pump starts.
If the above procedure is completed satisfactorily the pump controls are operating correctly and
the vacuum pump operation is proved.
Select the RESET display on each pump controller and all fault conditions should be cancelled.
Note: Refer to section 7.2 to complete commissioning of HTM 02-01 Vacuum Plant.

Initial Starting – Vacuum Pumps
a) Check that the isolating valves between the vacuum pumps and the vacuum receiver are
open. Check the sensing line between the control panel and outgoing pipeline has been
re-fitted following pressure testing.
b) Switch on the main isolator to the vacuum pump No.1. Check the rotation and then switch
off the isolator.
c) Switch on the main isolator to the vacuum pump No. 2. There is a time delay before No. 2
will start, to prevent simultaneous starting, following power failure (approximately 5
seconds). Check the rotation then switch off the isolator.
