Sunrotor SR-4 ( 24V) Solar Submersible Pump/Motor Unit
The SR-4 helical rotor submersible water pump offers a broad range of pumping capabilities and is the pride of our 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.
The SunRotor DC Input Controller SRC-M100T (our item number SPP-03205) is required in order to operate this pump properly. Running this pump with any other controller can result in pump failure and will void the warranty on the pump.
