Aquatec SWP-4000 Submersible Water Pump

The Aquatec SWP-4000 Submersible Solar Water Pump is one of the highest quality diaphragm pumps we know of and we are already getting positive feedback from our customers. These DC water pumps are made in the USA with proven reliablity, design and performance. Aquatec pumps have a strong high-grade stainless steel case (as opposed to the Shurflo‘s plastic enclosure) that allows the pump to go down as deep as 100 feet and gives it the capability to pump water up to 230 feet @ 100psi.  The pump can work off of 12 volts (or 24 volts when used with the Aquatec APC-30-250 controller).  However, more water volume is achieved by using the pump with 24 volts, as indicated by the chart below.

Aquatec SWP-4000 DC Submersible Pump
Key Features

  • Aquatec SWP-4000 fits well casings 4 inches or larger. (SWP-6000 fits well casings 6 inches or larger)
  • Capable of pumping from depths of up to 230 feet (compare to 120 feet for the SWP-6000)
  • Able to operate with voltages up to 30 VDC
  • Rugged stainless steel shell construction for optimum durability and corrosion
  • Factory installed 36 inch  12 gauge copper wire eliminates failure from improperly
    field-installed leads

    ID) or 5/8 inch (18mm) hose barb
  • Anti-wicking cable entrance protects the motor from an incorrectly installed splice
  • Over-sized eyelet for easy installation of safety line
  • Built-in 50 mesh stainless steel screen to prevent debris intrusion

  • Made in the USA

The Aquatec well pump has a brushed permanent magnet motor has an estimated operating time of 4000 hours and the three-chambered pump gives unparalled performance.  This DC water pump is designed for long time use but if service is ever required, the pump is easily field serviced.  After two to four years of operation it may be necessary to replace diaphragm, valves and motor brushes. Ask us about the full line of available repair kits.

Submersible pumps typically take a high surge current to start because they have such a small diameter. With the Aquatec pumps this doesn’t happen as it takes very little power to start the motor to move the diaphragm. This eliminates the torque reaction you would have with a regular pump.

Two 36 inch 12 awg input wires are preinstalled with double O rings to eliminate the chance of water intrusion at the wire input.  This has always been a problem with  Shurflo pumps.

Made in USA

Four-inch well casings are required for the Aquatec SWP-4000 pump. The Aquatec SWP-6000 can pump double the amount of water but it does require a well casing of 6 inches or more.

A 50 mesh stainless steel screen protects the pump from foreign dirt intrusion.  If the well has a sandy bottom, a well pump sock can be used (available from most pump distributors).

This solar pump has a dual port outlet for ½ inch (15mm) hose tubing (0.50 inch ID) or ½ inch Poly pipe.  As an option (.62 inch ID, which is equivalent to 5/8 inch (18mm) hose barb tubing can also be used. Pumping up to 230 feet requires 2.3 feet for 1 psi so the pump can produce 100 psi and high pressure pipe should be used accordingly.

Aquatec APC-30-250 Controller (optional)

Aquatec APC controller (not included with pump)
Optional Aquatec APC controller for use with Aquatec SWP series DC pumps

Up to 48 volts can be put into the Aquatec APC pump controller and this would regulate the voltage down to 30 volts.  This insures that more pumping can be achieved even on a cloudy day when a solar panel would be producing fewer watts.  The controller also has linear current boosting: in the event that a panel gets cold, and  produces an abnormally high voltage, the controller will lower some of the high voltage to boost the current.  This increases the pump’s efficiency to produce more water. The Aquatec APC-30-250 controller has all the features of (and can replace) the Shurflo 902-200 and the Shurflo 902-100 controllers, and has the added capability of an extended operating range, since many systems are no longer 12V.
