Solar Surface Pumps Lineup
Dependable, high-efficiency DC solar surface pumps engineered and hand-assembled in Oklahoma for over 40 years. Life expectancy of 15–20 years with regular maintenance, field-rebuildable wear parts, and ultra-high vertical lift.
Complete Surface Pump Lineup
High-efficiency positive displacement, rotary vane, and centrifugal solar surface pumps designed for off-grid domestic water, livestock ranching, high-volume irrigation, and extreme vertical lift.

SolarForce Piston Pump
Ultra-efficient positive displacement piston pump for heavy-duty off-grid service
Dankoff's flagship surface pump delivering up to 75% higher efficiency than centrifugal alternatives. Delivers strong volume directly from solar panels in low-light conditions with 15–20 year life expectancy with regular maintenance.
- Up to 9 GPM (34 LPM) & 230 ft (70 m) TDH / 100 PSI
- Dirt and dry-run tolerant positive displacement design
- 15–20 year service life with field-rebuildable wear parts

Solar SlowPump
Low-power rotary vane pump for remote springs, shallow wells & livestock
The pioneer of solar surface pumping since 1983. Draws water from shallow wells, streams, or springs with minimal solar array wattage and pushes up to 450 vertical feet.
- High vertical lift up to 450 ft (137 m) TDH
- Operates on as little as 100–300W of solar PV
- Self-priming rotary vane design with replaceable brushes

Flowlight Booster Pump
Constant city-water pressure for off-grid homes and gravity-fed supplies
Engineered to pressurize off-grid homes, cabins, and eco-resorts directly from low-voltage battery banks or solar arrays, delivering reliable 65 PSI household pressure.
- Provides city-standard 40–65 PSI household pressure
- Whisper-quiet DC permanent magnet motor
- Uses 1/3 to 1/2 the energy of conventional AC jet pumps

SunCentric Centrifugal Pump
High-volume centrifugal surface pump for crop irrigation and water transfer
Designed for maximum volume from shallow water sources. Pushes up to 70 GPM for open field drip irrigation, pond circulation, thermal storage, and tank filling.
- High volume output up to 70 GPM (265 LPM)
- Corrosion-resistant cast iron / bronze casing
- Direct solar PV-array or battery bank compatible

SolaRam Surface Pump
Extreme-head surface pump pushing water over mountain terrain up to 960 ft TDH
The heavy-duty solution for high-elevation livestock grazing and rugged mountainous terrain, capable of lifting water up to 960 vertical feet (293 m / 416 PSI).
- Industry-leading 960 ft (293 m) TDH / 416 PSI lift
- Massive cast iron mechanical power drive
- Pushes water over miles of pipeline in remote landscapes
