The SunRotor
®
submersible pump line offers a varied selection depending on the requirements.
From low cost to high yield, the SunRotor
®
Sales Team can find a solar pump system to fit nearly any
request. Both helical rotor and centrifugal pumps are offered, in a range of 12V to 110V brushless DC
motors. The conventional brushed DC motor maintenance and replacement is not necessary with
brushless DC motors.
The helical rotor series offers something that many pumps cannot: the ability to easily repair it in the
field. If the well has any abrasive substances such as sand, the rotor and stator can begin to show
wear and tear over time; however, with the SunRotor
®
Helical Rotor Repair Kit, it’s as easy as
removing the casing on your pump end, screwing in the new rotor, and placing the new stator in its
place in the pump end. After bolting everything back into place, the pump will run like it was new.
If for any reason the motor goes out (no matter the warranty status), the SunRotor
®
Technical Services
Team can most likely rebuild it, which is much more cost effective than purchasing a new pump.

ONTROLLER
The SunRotor
®
controller offers state of the art controller electronics, housed within a highly durable
metal weather resistant connection box with cooling fins cast on the back. It has a clear cover which
allows visible inspection of all of the connections and LED status lights. It offers a wide operational
range with max input tolerances of 50/100/200 volts DC, and it converts excess voltage into amperage
with its linear current boosting feature.
The controller also offers a timer function that is used to adjust the delay time for the low water
switch. The standard setting for the delay timer is 20 minutes, but can be increased by turning the
knob clockwise and reduced by turning it counterclockwise. This setting can be adjusted between 0
and 30 minutes while the controller is either on or off. The delay is designed to allow well recovery
before the pump is restarted. This significantly reduces the number of times the pump cycles on and
off throughout the day, and likewise, reduces the chance of damage to the pump from unnecessary
wear and tear.
Another option is the speed control. The speed knob adjusts the RPMs of the pump and has the
default position set to the maximum. Like the Timer Control Knob, clockwise movement increases
and counterclockwise movement decreases this value. Speed control can be useful in maintaining the
water level in a low producing well or water source, as it can be set to match the pumping speed with
the production level specific to the water source. Additionally, properly regulating the speed of the
pump can produce a more consistent water flow and prolong the life of the pump, as there will be
less startups each day. The speed control can be adjusted with the system on or off.
