SR-12 Helical Rotor Solar Pump

The SR-12 is the largest of the SunRotor Helical Rotor Pumps. It produces a substantually higher volume in the lower lift areas and is cable of handling depths far greater than any helical rotor pump we’ve sold in the past.

This pump can and must be used with SRC-M200T Solar Pump Controller. Attempting to run our pumps from any other controller can result in pump failure and void the warranty on the pump.
