East Butterwick Pumpstation, UK
		The project: Renovation of a pump station in East Butterwick, North Lincolnshire, Great Britain Executing companies: T-T Pumps Ltd., Cheshire Messingham Internal Drainage Board The pump station was built after the Second World War and is used to pump off flood water.
The problem: In 1981 our partner, T-T Pumps Ltd., equipped this pump station with two TO500B855 units, each with a 55kW power rating. 900 litres per second is moved at a height of 4,5m. The operating range should additionally be between 0m and 7,5m. Although the pumps have run for twenty-three years without failure or need for spare parts, the Messingham Internal Drainage Board decided in 2004 that the pumps had reached the end of their lifespan.
		Our solution: Again, T-T Pumps Ltd. won the bid. The solution that was offered was simple and inexpensive: In 2005 it was possible to employ two new type TO500B855 pumps of the latest design to be operated for another 24 years – without risks or large-scale reconstruction. The installation of the pump control developed by T-T Pumps Ltd. has now made it possible for the pump station to be used for draining the surrounding fields during dry periods.

With regards to the above application wear and tear can take place mainly in impeller, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
