Solar Pumps

RanchPump RP4


API’s RanchPumps reflect our more than 25 years of solar pump engineering and manufacturing, allowing us to build the industry’s best pump.

These pumps are constructed with a stainless steel housing and cap. They are designed to provide a longer pump life, increased strength, and trusted durability. These pumps dissipate heat more effectively than PVC pumps. This thermal protection extends the life of the motor. These pumps are submersible, factory rebuildable, lightweight, and built in the U.S.

  • Pumps 3.7 GPM max.
  • 125 feet (54PSI) maximum lift/pressure.
  • CNC manufactured and engineered tough lifetime 304 Stainless steel.
  • Rugged stainless steel for great abrasion and corrosion resistance.
  • 180-watt 1/5HP Brushless 12-36 VDC heavy duty motor.

  • Lightweight and durable.


  • Maximum 6.5-7.2 pH-balance water, (these pumps are not intended for saltwater)
  • Maximum operating pressure: 54PSI or 125FT of vertical lift
  • Maximum depth under static water: 50’
  • Maximum operating temperature in water: 100°F
  • Shipping weight: 13 pounds
  • Includes 100’ of 14-2 pumps cable connected to pump
  • No external drives or controllers required
  • Reverse polarity protection
  • Limited overvoltage protection
  • Positive displacement
  • Factory rebuildable
  • Temporary run dry capability
  • Pressure relief valve


  • Minimum 5” well casing.

  • ½” male NPT coupling.

  • Must register the RanchPump for the 3-year warranty.


API solar water pumps do not require a controller, however the ALC 1275 greatly increases the life expectancy of our aluminum pumps and prevents unnecessary wear and tear on the pump.

Available in these systems: KS05, KS10, KS17

150 and 200 feet wire rolls are available. There is a $35.00 up charge for each additional 50 feet of wire.
