摘要

Four 11kW line shaft-driven pumps, first installed in 1992, were running without any form of variable speed control. They have been replaced with two 45kW submersible sewage pumps, the flow rate of which is controlled by two ABB water drives. The upgrade increases pumping capacity and delivers substantial energy savings, as the ABB drives ensure that the pumps only operate at the speed required. Prior to the upgrade, the average pump running time was 14 hours per day. Following the upgrade, the average run time was reduced to three hours per day. This reduction in energy led to an estimated £4,000 annual saving for Anglian Water.
