Product Details

DAYLIFF SUNFLO-X Range of pumps are high specification solar powered centrifugal and helical rotor DC pumps specifically designed for borehole applications and feature a remote surface mounted controller. Pumps are constructed principally from AISI 304 stainless steel and are engineered to the highest standards to give serviceability, excellent efficiency, high reliability and long life. Helical rotor type are supplied with spare rotor.

Motor
Pumps are fitted with Permanent Magnet brushless high efficiency, maintenance free DC motors without integrated electronics specifically designed for maximum efficiency. They should be powered by solar arrays configured to provide the input voltage required and sized at approximately 130% of the rated motor power.

Controller
Pumps are provided with matched controllers for monitoring, protecting and controlling pump operations with the following features:-

• Protection against reverse polarity, overload and over temperature.
• Integrated MPPT (Maximum Power Point Tracking) with 99% energy conversion efficiency to maximize module power output.
• Fully automatic operation and complete protection including low level control, dry running and over/under voltage.
• Enhanced pump start on low sun intensity.
• Easy trouble shooting, where fault code is displayed on LCD screen for fast identification and problem solving.
• Enclosure Class: IP52
  

Power Outputs
Performance curves are given at standard test conditions of 1000W/m solar irradiance and 25°C. 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.
