4. Safety, Operation and Maintenance Instructions
4.1 General – tools and facilities
Care should be taken at all times to ensure that any tools are used safely for the purpose for
which they are designed and in accordance with the manufacturer’s instructions. Ideally the
pump should be installed using a drive, with facilities to inch the pump along and which is able to
operate in reverse. Any maintenance work will require a complete set of metric spanners, a
socket set and torque wrench; you should check your fastener kit to ensure you have all the
correct sizes available
Specialist lifting equipment will be required for several of the procedures below (large size pumps
only: VF25 - VF80). The lifting equipment to be used should be checked for suitability for the
task and capability of lifting the combined weight of the pump components. Always follow the
manufacturer’s instructions for safe operation of lifting equipment (See Appendix C for guidance)
