PUMP
The Dayliff DB/DBH range of horizontal multistage centrifugal pumps are
designed for continuous duty in various water transfer duties with particular
application in pumping slightly corrosive liquids. The pump has small
physical dimensions, axial suction port and radial discharge and is base
plate mounted. DB suction chamber and pump head are made of grey cast
iron while the impeller and impeller housing are of stainless steel. DBH pump
body, suction and discharge ports are made from AISI 316 stainless steel as
is all the other parts in contact with the pumped liquid. The mechanical seal is
made from silicon carbide designed for easy replacement. Both pump and
continuously rated motor unit are of monoblock design and particular
attention has been paid to quietness and smooth operation.
MOTOR
The pump is coupled to a totally enclosed, fan cooled single phase squirrel-
cage motor with built in thermal overload protection suitable for continuous
duty. The motor can be connected to a power outlet fuse or MCB and
protection must be provided.
