SQFlex Submersible Pumps
This is the ultimate submersible pump for water lifts of up to 525 feet. They can be directly powered by solar or wind power or can be run on an inverter, a generator, a battery or the utility grid, or any combination of these sources. Virtually any source of power, 30-300 VDC and 90-240 VAC, can be used to run the pump. And with Grundfos, you know it is built to last and is maintenance-free. Some SQFlex pumps will fit into a 3″ well.
9300 Submersible Pump
Use this lightweight submersible pump for livestock, irrigation or remote home application with low water requirements. The 9300 is a positive displacement diaphragm type pump with very high efficiency, but a much shorter life than centrifugal or helical rotor pumps. Diaphragm should be replaced every two to four years, depending on pumping volume.
The SHURflo 9300 can be operated on a 12- or 24-volt battery, or, with the use of one of the SHURflo Pump Controls, directly on a PV array. The pump can lift 1.3 gpm to 230 feet and can pump nearly 2 gpm from very shallow wells. It measures only 3.75″ diameter x 12″ long. Performance on a 12-volt battery will be less than half the flow on the accompanying table. 1-year warranty.
SD DC Submersible Pumps
SunPumps SDS series submersible pumps are efficient, low voltage, DC powered, diaphragm type positive displacement pumps designed specifically for water delivery in remote locations. They operate at 12 to 30 volts DC which may be supplied from a variety of independent DC power sources. There are two models of SDS pump. The D-series has a dual diaphragm and fits in a 4-inch well. The Q-series is a higher flow pump that fits in 5-inch or larger wells. They can be used to fill an open tank or in pressurized water delivery systems. Simplicity is the key feature of the SDS series pumps. They are easy to install, require very little maintenance and are repairable. Use the table to choose the pump that best meets your flow need at a given head. A PCA-30-M1 controller must be used with all SDS pumps. At 15 volts, flow is slightly less than half of the 30-volt flow.
2088 Pressure Pumps
These positive displacement diaphragm pumps make excellent household pressure pumps if you need less flow than the booster pumps deliver. The SHURflo 2088 pumps up to 3.6 gallons per minute, is designed for continuous-duty operation with addition of optional heat sink, and can be run dry without harm. It has a built-in pressure switch and half-inch male pipe-thread ports for easy connection to common plumbing fittings. Home pressurization installation requires a precharged water tank. For general water pumping, this pump can self prime to 10 feet and lift water up 100 feet. The 120-volt AC version can run on a 200-watt inverter and can be 1000 feet from the inverter using 12 gauge wire. Dimensions: 4.45″ x 12.4″ x 5″.
530 Series Pressure Pumps
These Aquatec booster pumps provide “town pressure” for remote home water supplies where 12-volt or 24-volt power is available. They have a longer life and greater flow rate than other diaphragm booster pumps and they use less than half the energy consumed by an AC jet pump running on an inverter. The 120-volt version can be used on remote power systems with inverters.
The slow pump can push water as high as 450 vertical feet. It runs on very little power, with or without batteries, to supply between 200 and 2600 gallons of water per day. The positive displacement vane pump mechanism is housed in forged brass, and lasts for years of all-day running. 5-micron filtration is required to protect the pump. For PV-Direct (no batteries in system) array, watts must exceed pump watts by 20% or more, and a linear current booster controller is required.
