Pump installation is a common MEICA task on water treatment, sewerage, and process plant projects. Pumps range from small submersible units to large centrifugal pumps weighing several tonnes. Incorrect installation or misalignment causes premature bearing failure, seal leaks, and vibration damage. This talk covers the safe handling, installation, and alignment of pumps on UK construction sites.
Key Hazards
Crush injuries from heavy pumps during manual handling or lifting
Finger and hand entrapment in rotating pump components
Pressurised fluid release from incorrectly connected pipework
Electrical shock during pump motor connection and testing
Control Measures
Use lifting equipment with a current LOLER certificate for all pumps too heavy to carry safely.
Check the pump weight and lifting points before planning the lift procedure.
Ensure the baseplate is level and grouted before setting the pump in its final position.
Use a laser or dial indicator alignment tool to achieve the specified shaft alignment tolerances.
Isolate and lock off the electrical supply before connecting or disconnecting pump motors.
Confirm all pipework connections are tight and supported before commissioning.
Install coupling guards before the pump is energised or test-run.
Carry out a bump test to confirm correct rotation direction before full-speed operation.
Record all alignment readings and commissioning data for the handover documentation.
Remember
Always use lifting equipment for pumps that are too heavy to carry safely by hand
Achieve the correct shaft alignment using laser or dial indicator tools before commissioning
Isolate and lock off electrical supplies before any motor connection work
Install coupling guards before the pump is energised or operated at any speed
Carry out a rotation check (bump test) before running the pump at full speed
