The DAYLIFF DDPS 60 are solar booster pumps suitable for water transfer in small scale applications where grid power is unavailable. It is constructed of cast iron pump body, aluminium motor body, peripheral brass impeller and silicon carbide mechanical seal.
Inbuilt controller that provides thermal and over voltage protection
Can be connected directly to a 500W,24V PV power supply
Pump is coupled to higher efficiency permanent magnet brushless DC motor rated for continuous operation
Power Outputs Pump output 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 East Africa. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2.
Pumped Liquid: Thin, clean, chemically non-aggressive liquid without solids or fibres Max. Ambient Temperature: +350C Max. Liquid Temperature: +400C Max. Liquid Temperature: 7m at sea level
