ISO PRO Centrifugal Pump
Section 6.....................................................Commissioning and Operation
1. SAFETY INSTRUCTIONS FOR COMMISSIONING & OPERATION
• Do not touch any moving or rotating parts.
• Guards must be in place before operating the equipment.
• Check that the pump is primed. Pump should never be run dry as the pumped liquid acts as a
lubricant for the close running fits surrounding impeller and damage will be incurred.
• Failure to supply the stuffing box or mechanical seal with cooling of flush water may result in damage
and premature failure of the pump.
• Do not touch surfaces, which during normal running will be sufficiently hot to cause injury. Allow
sufficient time for cooling before maintenance. Be cautious and note that other parts of the pump
may become hot if a fault is developing.
• In addition to local or site regulations for noise protection, Pentair Southern Cross recommend the
use of personal ear
protection equipment in all enclosed pump rooms and particularly those containing diesel engines.
Care must be taken to ensure that any audible alarm or warning signal can be heard with hearing
protection worn.
These operations must be carried out by fully trained and qualified personnel
2. PRE-COMMISSIONING PROCEDURE AND CHECKLIST
The following steps should be followed at initial start up and after the equipment has been overhauled:
a) Confirm correct pump is fitted into the designated functional location.
b) Prior to installing the pump, flush the suction side of the system to remove all deposit (slag, bolts
etc). Remove all pre-commissioning screens and replace with operational units.
c) Ensure the pump and piping is clean. Before putting the pump into operation, the piping should be
thoroughly back flushed to remove any foreign matter which may have accumulated during
installation. Take all possible care not to contaminate your system.
d) Inspect all nozzle connections for
i. Missing bolts or loose bolts
ii. Missing gaskets
iii. Flange alignment / Misalignment
e) Check Pipe work for
i. Correct sizing
ii. Any suction restrictions
iii. Make sure that all hold down bolts are in place and pulled down
