1.3 Items and tools required for the safe, effective and efficient conduct of servicing and maintenance tasks are identified

1.4 Support required for the safe completion of the servicing and maintenance tasks are identified and arranged

1.5 Isolation and lock-out of all equipment necessary for the safe execution of tasks is carried out in accordance with site requirements and procedures

2 Carry out pump maintenance 

2.1 Pumps are inspected and any faults reported in accordance with site and manufacturer's requirements and procedure

2.2 Maintenance tools and equipment are selected and used safely

2.3 Servicing  and maintenance of pumps is carried out in accordance with the work requirements, manufacturer's current specifications and site requirement

2.4 Hazardous and emergency situations  are recognised and responded to in accordance with legislative, site and manufacturer's requirements and procedures

2.5 Used oil, lubricant and other waste is disposed of in accordance with legislative and site requirements

2.6 Servicing and maintenance records are maintained in accordance with site requirements

3 Prepare the pumping system

3.1 Operation and function of pump and driver is checked by applying principles of operation and procedures

3.2 The operational area is checked to ensure that any potential hazards which may affect the operation of the equipment are removed

3.3 Pre-start-up checks are conducted on the pumping system  to ensure valves are correctly sequenced and filters are clear before commencing pumping operations, and that all safety requirements are met

4 Start up and shutdown pumping system

4.1 Ancillary equipment  is operated in accordance with procedures.

4.2 Pump is started up and shutdown in line with procedures

4.3 Emergency shutdown procedures are implemented when required

5 Operate and monitor pumping and ancillary systems

5.1 Flanges, gaskets and seals are checked and maintained within stated operational tolerances and to avoid any environmental damage

5.2 Pump pressures and flows are monitored for conformance

5.3 Amperage testing equipment is used to monitor and identify variations in the operating conditions of the pumping systems/equipment

5.4 Pumping systems/equipment performance and all components are monitored and regularly checked to identify any signs of excessive wear and diminution of performance

5.5 Operational valves and valve assemblies are checked for possible leakages

5.6 Filter systems are periodically checked and cleaned to remove any potential blockages or impurities entering the pumping system/equipment and causing it to cavitate or malfunction during operation

5.7 Lubrication oil is inspected and sampled to check that operating levels are correct and to determine if any contamination has taken place which may affect the operational capacity of the pumping system/equipment

5.8 Appropriate action is taken resulting from checks and monitoring

6 Shut down the pumping system

6.1 Injection equipment is shut down according to workplace procedures

6.2 The pump is shut down according to workplace procedures

6.3 Pumping equipment is cleaned according to workplace procedures

6.4 Waste generated by both the pumping process and cleaning procedures is collected, treated, disposed of or recycled according to workplace procedures
