PUMP
Dayliff DSD range of Submersible Multistage centrifugal pumps are specially
designed for domestic and small scale water supply from wells and boreholes.
Material of construction include polycarbonate impellers and diffusers, cast iron
delivery and suction chambers and AISI 304 stainless steel pump housing, shaft
and shaft coupling. These quality materials together with the polycarbonate
impellers provide the pumps with excellent sand handling capabilities for a
longer life. DSD 3/7, 3/13 and 3/18 are supplied complete with 30m cable and
control box.
MOTOR
The pump is coupled to a sealed liquid cooled 2-pole asynchronous squirrel-
cage motor constructed of stainless steel. Single phase motors should be
supplied with purpose designed Dayliff SCM control boxes for operation and
protection against overload, dry running and over/under voltage. Three phase
motors require a remote DOL starter; A DAYLIFF SCT electronic Pump Controller
is recommended for comprehensive pump control including low level, motor
overload and irregular power supply protection.
