Fiddlers Ferry power station consists of four units generating 500 MW, each containing a Mather & Platt 16”-16” Plurovane main boiler feed pump (MBFP) directly driven by a steam turbine, together with two start & standby boiler feed pumps (SSBFP) driven by variable speed motors. Up to the 1990s, the station generated at full load power totalling 2000 MW, as per the original design. During this period the MBFPs were operating almost nonstop. This optimum condition resulted in a reasonable
