SR-26 Pump & Controller


The SR-26 Centrifugal Pump is the highest flowing submersible pump in the SunRotor fleet. We have bundled it with our SRC-M100T Controller. This pair is perfect with low TDH to produce high flow rates.

• 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 26 GPM (98.42 LPM)
• Durable stainless steel impellers
• 6 impeller stages
• 1.5 inch (38.1 mm) FNPT output port
• Check valve built into the pump
• 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
