SR-16 Centrifugal Solar Pump

SR-16 Centrifugal Solar Pump


The SR-16 is one of the most powerful pumps we currently offer in the SunRotor fleet. This multi-stage propeller pump can get you to those low depths you need and still perform brilliantly. At mid-range pumping heights, this pump out-performs them all.

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 72 volt operation
• 200 Voc maximum input voltage
• Power range 855 watts to 1560 watts
• Solar, battery or a combination
• Maximum functional lift capability of 425 ft (137.2 m)
• Max flow at 100 ft (30.5 m) is 16 gallons/min (60.57 liters/ min)
• Submersion limit of 100 ft below static water level (ex: 100 ft submersion + 50 ft static water level: 150 ft)
• 4" diameter (102 mm) fits 4.5" (114 mm) casing** 
• Weight of 27 pounds (12.5 kg)
• Submersible motor protected from ambient water by oil filled jacket (vegetable based 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
• Multi-stage Impeller Pump
• 1.25" (32 mm) FNPT outlet
• Check valve built into the pump
• 304 Stainless Steel pump body and impellers
• CE certified
• ISO 9001

**The SR-16 may fit 4" casing if the cable guard is removed from the pump end.
