Solar Surface Pumps & Protection Hardware
Engineered and manufactured in the USA for over 40 years. Field-proven DC solar surface pumps with 15–20 year life spans (with regular maintenance), ultra-high lift capability up to 960 ft TDH, and genuine OEM protection accessories.
Solar Surface Pumps 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
System Protection Accessories
Maintain continuous hydraulic prime, filter fine abrasive sediment, and automate tank level management with genuine factory-tested accessories.
Heavy-Duty Foot Valve
Machined brass check valve with perforated stainless steel strainer
Stops coarse intake debris, gravel, and leaves from entering the suction line while maintaining continuous hydraulic prime between pumping cycles.
- Perforated corrosion-resistant stainless mesh
- Precision internal check seat preserves prime
- Submerged intake protection for streams & wells
SJE PumpMaster SPDT Float Switch
Mechanically-activated SPDT switch for automatic pump-up and pump-down
P/N 1004836 with 15 ft water-resistant SJOW cable. Automatically shuts off the pump when storage tanks are full, or protects the system in low-water intake conditions.
- 15 ft heavy-duty SJOW water-resistant cord
- SPDT contacts: Pump-Up (tank fill) & Pump-Down
- Adjustable pumping range from 7″ to 36″
EZ Install Kit & 10″ Inline Filter
Pre-assembled true-union plumbing assembly with 10-micron filtration
Includes reinforced 10″ filter housing, washable 10-micron pleated core, true-union isolation valves, liquid-filled pressure gauge, and brass drain port.
- 10-micron washable pleated filter cartridge
- True-union ball valves for tool-free servicing
- Liquid-filled pressure gauge & drain valve
Dry Run Safety Protection Switch
Prevents mechanical seal burnout by shutting down power upon loss of suction flow with a manual reset button protocol. Explore our complete Accessories Architecture Guide for detailed plumbing schematics and technical installation protocols.
