Dankoff Solaram Diaphragm Pumps

Dankoff Solaram Diaphragm Pumps

Solaram diaphragm pumps use industrial-grade, high-pressure, multiple-diaphragm pump heads, and PM motors for either 24 VDC array-direct or battery operation, or 120 VDC (nominal) array-direct operation. Solaram pumps can be used for domestic, agricultural, commercial, or industrial applications.

The Solaram is Dankoff's most powerful surface pump. They can draw water from a shallow well, pond, stream, river or storage tank. They can push water very high up-hill (960' maximum head), through miles of pipeline, or for pressurized water systems (415 psi max; minimum 60 gal. pressure tank required). Suction capacity is 20' at sea level (subtract 1' for each 1000' above sea level). With 2.5-9 gpm of pumping capacity, Solaram pumps can supply up to 5,400 gallons per day (GPD), while using less power than any other pump in its range. They start pumping even in low light conditions.

These pumps are rugged and reliable, as well as dirt and dry-run tolerant. They feature multiple-diaphragm industrial construction, a cast aluminum body and massive ball bearings, and Permanent Magnet (PM) motors. They do require preventive maintenance every 2 years (based on full year-round use), consisting of oil changes (non-toxic oil) and diaphragm replacement, but have a 20-year life expectancy. A pressure relief valve is included.

For array-direct operation at 24 VDC, use 36-cell PV modules in series-pairs and then with pairs in parallel to get the total power needed. For array direct operation at 120 VDC, use ten 36-cell modules in series, or six 60-cell modules in series. Add series sets in parallel if more power is needed. As with other array-direct pumps, the PV array needs to be sized at least 20% larger than the pump watts, and even larger arrays can be used to extend pumping in lower light conditions.

A linear current booster (LCB) is required to prevent stalling in low light conditions. LCB's for 120 VDC Solaram pumps are custom built by special order. Contact AEE for more information.

Solaram pumps can develop pulsating water pressure up to 400 psi, so the piping system must be designed for high-pressure use, at least 600 psi is recommended for at least the first 200' of head (this generally means using steel pipe). The pulsation and pressure is relieved as the pipe climbs the hill, so pipe with a lower pressure rating can be used.

Suction capacity is 25' at sea level (subtract 1' for each 1,000' above sea level). Fittings are 1"-1.25" on the intake, and 1" on the outlet. Dimensions are 28"W x 16.5"H x 16"D, and they weigh in at 150 lbs (max, depending on model). 1-year warranty.
