Ballast Pump · Pumps
A horizontal centrifugal pump operates by using a rotating impeller to impart velocity to the fluid being pumped, converting rotational energy into kinetic energy. The BD Marine Centrifugal, manufactured by Bryan Donkin, exemplifies the UK heritage in marine equipment. Its capacity ranges from 100 to 2000 m³/h, making it suitable for handling sea water and ballast. The pump comes in various DN sizes from 80 to 250 mm, with a head range of 10 to 75 meters. Originally produced between 1955 and 1990, the BD Marine Centrifugal features electric or steam turbine drives and is constructed from cast iron and bronze. Common issues include aged sealing technology, bearing wear after long service, impeller erosion, and casing wear. Due to its legacy status, spare parts are sourced through niche refurbishers who often hand-fabricate components, and the pump requires refurbishment by specialized UK heritage pump specialists.
