Rockford Solar-Electric Piston Water Pump™
The new Rockford Solar-Electric Piston Water Pump™ is a simple and sturdy low-amp positive displacement piston pump ideal for farm, rural and ranch use.For durability and long life, the motor and downhole well components are of higher quality materials, including several stainless-steel parts, with no PVC plastic. The compact motor above the wellhead makes installation and servicing easy and safe. Operation is steady and quiet. There are no emissions.
The Rockford pumps up to 400 feet deep with a ¼-hp motor driven by off-grid solar panel with batteries, solar alone or with low-amp grid-tie. The motor is a simple-operating linear driver with few moving parts. A reciprocating piston pulls water, using the efficient and long-proven technology of an oil-field pump jack. Flow rates are a constant 1.1 gallons per minute (1,584 gallons per day) at any depth. Power draws range from a minimum 3 amps up to 8.8 amps at 400 feet.
