Cold water pump gets a rebuild after 20 years loyal service
Qualtex was invited to site to remove this cold water pump for a complete rebuild. The pump acts as an auxiliary cold water pump for a 250MW thermal generator in the North Island of New Zealand.
As the pump had been in operation for over 20 years without a service, the condition of much of the assembly had suffered years of corrosion making disassembly a real challenge. The depth of the well at 12 meters also presented a challenge as the pipe work needed to be lifted and removed in a series of 3 meter sections at a time.
Without an available procedure for the removal, the team set out in the scoping phase to establish a methodology for the safe and efficient disassembly, removal, rebuild and reassembly.
