Solar pumping is now firmly established as the technology for water supply in remote off-grid applications and also as the costs reduce increasingly for general pumping duties. Dayliff have been leaders in the technology since the birth of the industry and today offer a wide range of options for every solar pumping requirement imaginable. Particularly a range of competitive, high specification solar pumping systems have been developed for smaller scale applications which are based on robust submersible solar pumps specially designed for PV powered water supply from wells and boreholes.
Together with the pump all systems include:-
Module supports and piping are not included. The various systems offered give a wide range of duties, indicative performance being given. Full details of pump performance and specification is given in the Dayliff Product Manual and should be referred to when selecting equipment.
Positive displacement type of three chamber diaphragm design. They are manufactured from high quality engineering plastics with plastic casings for the 150 model and stainless steel for the 300. Pumps can be connected directly to a 24V PV power supply for daytime only pumping or through a charge controller connected to batteries for extended daily operation.
All models are of helical rotary screw stainless steel design for high efficiency and feature an inbuilt controller that gives operating protection for direct connection to the PV modules. All models are of narrow 3” diameter specifically designed for boreholes.
Higher specification pumps of both helical rotor and centrifugal type that are provided with separate controllers that feature MPPT technology to maximise pumping output as well as providing electrical protection and indicator lights giving operating status. Battery connection is also available for extended daily pumping.
