Aquatec SWP-4000 Submersible Solar Water Pump
Aquatec SWP-4000 submersible pump is designed to run on solar and provides water in off-grid places for people, irrigation, livestock, ponds, and a variety of other uses. The SWP-4000 is a positive-displacement submersible deep well diaphragm pump. It’s made with potable-water safe materials and is safe to use for people, pets, and livestock. The SWP-4000 solar water pump is designed to run from any 12-30-Volt DC power source - battery, wind, or solar. The SWP-4000 requires a drop pipe diameter of 1/2” and a casing or well size of 4” or greater.

Pre-Packaged Aquatec SWP Solar Water Pumping Kits
We’ve gone ahead and done all the planning for you. Solar water pumping kits you can install. It’s very easy and if you have questions you can email us. You’re getting full tech support working with The Solar Store.
The Aquatec SWP-4000 works with a well casing of 4” or larger, if your well casing is 6” or larger with a head height of 120-feet or less check out the Aquatec SWP-6000.
Aquatec SWP-4000 Replacement Parts and Service Kits
The Aquatec SWP-4000 should be regularly serviced every 2 to 4 years depending on usage. It's field serviceable and there isn’t a need for complex tools. Common parts to replace are the diaphragm, valves, and motor brushes. Aquatec makes it pretty easy.
Power the Aquatec SWP-4000 Directly off Solar
You can power the Aquatec directly off of DC power sources, battery, solar, and wind. The SWP-4000 pump draws 3.7 amps (111 watts) at 30 VDC.
The operating voltage range is 12 volts minimum to 30 volts maximum. For optimal performance, a solar panel/array of 180 watts or greater is recommended. On a partly bright day, a higher wattage solar panel/array would best assist the pump's functioning. The solar panel(s) should be placed as close to the pump as possible, ideally, in an area that receives direct sunlight from 10 a.m. to 3 p.m.
Calculate Minimum Solar Array for Aquatec SWP-4000
In certain solar water pumping applications, you might not need the max performance of 180-watts of solar. In order to calculate the minimum solar array size required for your specific application, you’ll need to know your head height and reference our chart below. Head height is the distance you need to pump the water.
Once you know your head height you can view the chart below to see what the amp draw will be. You’ll then need to do a small calculation to determine the minimum wattage needed for your solar array.
Use the formula Voltage X Amps X 1.25 (25%) = Watts.
For example, if your head height is 40 feet and you want to use a 24-volt solar panel. NOTE: solar panels have nominal voltage but the actual voltage is greater. For 24-volt panels use 30 volts, and for 12-volt panels use 18-volt in your calculations.
Our calculation would be 30 (volts) X 1.7 (AMPS) X 1.25 = 64-watts.
Keep in mind that this is in clear, sunny skies. If you frequently see clouds or shade you’ll want to increase this, even double it sometimes. More wattage just means you’ll be able to pump during less than optimal sun. Just don’t go over 30-volts for your solar array.

Aquatec SWP-4000 vs Shurflo 9300
Aquatec SWP-4000 is a direct competitor to Shurflo 9300. And if you’re looking for a great water pump that works directly off of solar, battery, or wind power, the Aquatec SWP-4000 is a great choice. It’s manufactured right here in the U.S. and is less expensive.
Aquatec also addresses an issue the Shurflo 9300 has with water leaking into the housing during the wire install. To combat this Aquatec is wiring the power cable directly from the manufacturer and adding anti-wicking to the wire splice to prevent any water ingress.
The Shurflo 9300 does have a leg up when it comes to pumping water. It has slightly larger water flow as compared to the Aquatec SWP-400, but if you have a well casing that is 6” or larger you can always go up to the Aquatec SWP-6000 for a greater flow rate. The GPM of the Shurflo 9300 at 20 feet head is 1.95 GPM as compared to the Aquatec's 1.7 GPM . Towards the 230 foot lift the GPM are fairly equal at 1.36gpm ( Shurflo) and 1.25gpm (Aquatec).
