SR-26 Centrifugal Solar Pump

SR-26 Centrifugal Solar Pump


The SR-26 centrifugal pump is the highest flowing submersible pump in the SunRotor fleet.

All SunRotor pumps require a SunRotor DC Input Controller to operate properly. Attempting to run our pumps with any other controllers can result in pump failure and will void the warranty on the pump.

• Nominal 48 volt operation
• Usable voltage range 24-48 volts
• Power range 285 watts to 1140 watts
• Solar, battery or a combination
• Maximum functional lift capability of 130 feet (40 m)
• Max flow at surface level is 32.6 GPM (123.4 LPM) with 556.4 watts and 70.8 volts PV nominal input
• Durable stainless steel impellers
• 6 impeller stages
• 1.25 inch (32 mm) FNPT output port
• Submersion limit of 100 ft below static water level (ex: 100 ft submersion + 50 ft static water level: 150 ft)
• 4 inch diameter (102 mm) fits 4.5 inch (114 mm) casing
• Submersible motor protected from ambient water by oil filled jacket (food grade oil protects potable water source if vessel is compromised)
• Brushless DC motor technology avoids conventional DC brush maintenance and replacement
• All electronics are mounted above ground for longer life and easy access
• Entire pump body is stainless steel to comply with all local code and pump installation requirements
• CE certified
