Sunflo A2



DAYLIFF SUNFLO-A2 pumps are specifically designed for PV solar powered water supply from wells and boreholes. They are of rotary screw design and material of construction for the rotary screw is stainless steel with a rubber stator. Pumps are of simple structure and feature an inbuilt controller with automatic low level (dry run) protection.

MOTOR
Permanent magnet, oil filled, brushless, DC motor specifically designed for maximum efficiency from solar module power source. It should be powered by solar array configured to provide the input voltage and sized at approximately 150% of the rated motor power.

PUMP 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 temperature 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.
