DAYLIFF DSOLARX 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.
Pumps are fitted with Permanent Magnet brushless high efficiency, maintenance free DC motors without integrated electronics specifically designed for maximum efficiency for solar module per sun. They should be powered by solar arrays configured to provide the input voltage required and sized at approximately 130% of the rated motor power.
Insulation Class: F
Enclosure Class: IP68
Pumps are provided with matched controllers for monitoring, protecting and controlling pump operations with the following features:-
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 liquids without solid and fibres.
Maximum Liquid Temperature: 0 - 350C
Controller Ambient Temperature: -200C to +600C
Max Immersion Depth: 250m
Minimum Borehole Diameter: 125mm
