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.
