PUMP
DAYLIFF DDA submersible multistage centrifugal pumps are designed for
pumping clean, non-aggressive water in various domestic and light duty
applications. They are particularly suitable for wells and boreholes, though can
also be used for water transfer from tanks, irrigation and pressure boosting
applications as an alternative to a conventional dry mounted pump. A particular
design feature is the jacketed motor arrangement which provides excellent
cooling and allows the pump to work semi-submerged. The pumps’ design
features mechanical seals (twin on DDA1200C2) in an intermediate oil chamber
for greater pump reliability and pump construction is Polypropylene impellers and
diffusers and stainless steel pump casing.
Pumps can be fitted with a pressure controller for automatic operation. All pumps
are supplied complete with 20m cable.
DDA1000P & DDA1200C2 are fitted with a low level float switch with adjustment
clamp and an inbuilt capacitor for simplified installation and are particularly
suitable to well and tank applications.
