The Eco Solar System - SDS-Q-135

The "ECO" Submersible System is best suited for bores that will not yield large volumes or if the need for high volumes of water is low. The system uses a SunPumps SDS (piston diaphram) pump.
- Works from depths up to 30 Metres (100 ft), with little capital cost.
- Delivers from 600 to 10,000 litres per (solar) day
- Choice of fixed or tracking array solar panels
- Option of floating pontoon
- Systems start in price from as little as $ 3,500.00
SunPumps SDS series submersible pumps are highly efficient, low voltage, DC powered, diaphragm-type positive displacement pumps designed specifically for water delivery in remote locations.
They operate on 12 to 30 volts of DC current that may be supplied from a variety of independent DC power souces. Constructed of marine grade bronze and stainless steel, these pumps are the highest quality submersible pumps in their class.
SunPumps SDS series pumps can be installed below the water level in a pond, river or well, or installed by hand into a bore. They can be used to fill an open tank, or in a pressurized water delivery system. Simplicity is the key feature of the SDS series pumps. They are easy to install, require very little maintenance and are repairable.
