DAYLIFF SUNFLO-A Solar Submersible Pump - Dayliff | Great Pumps, Great Value

Product Overview

Product Details

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 huge 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:-

  • The appropriate specifications and number of Grade 1 PV modules with connectors for simplified installation
  • Submersible drop cable and joint together with 10m module connection cable
  • DC solar isolator with MCB control provided for module isolation
  • Safety rope and HDPE pipe connectors

Pump components are manufactured from high quality engineering plastics with santoprene used for the diaphragm and EPDM for the valves.
Pump casings is stainless steel and a 50-mesh stainless steel screen. Pumps can be installed either with a direct connection to the PV module or through a charge controller that is connected to a battery for 24hr operation. Pump output will be determined by the PV module input power available.

SUNFLO-S
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.

MOTOR
The pump is fitted with of permanent magnet type totally enclosed brushless motor with 24V DC power input from either a direct source or photovoltaic modules. Internal thermal protection is also provided.

PUMP OUTPUTS
Performance curves are given at standard test conditions of 1000W/m2 solar irradiance and 250C. Output will vary throughout the year depending upon prevailing irradiation levels. For estimated daily outputs at continuous pumping multiply the indicated output at the duty point by the daily irradiation given in Graph 1. For indicative purposes factors of 1.1 can be applied for hot arid areas and 0.9 for temperate high altitude areas in the Tropics. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2.
