DAYLIFF SUNFLO-A 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 rotary screw is stainless steel with a ruber stator. Pumps are of simple structure and feature an inbuilt controller.
MOTOR Permanent magnet, Oil-filled, brushless, DC motor specifically designed for maximum efficiency from solar module power sources. It should be powered by solar array configured to provide the input voltage required and sized at approximately 130% of the rated motor power.
PUMP OUTPUTS Pump output curves are given at standard test conditions of 1000W/m² solar irradiance and 25°C. The 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 East Africa. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2.
