MAINTENANCE
Controller: The controller is electronic with no moving or wearing parts. It requires no maintenance
beyond checking for dust, moisture or insect infestation. Inspect all seals to insure that the
controller is kept dry.
Pump Motor: The motor is oil-filled and brushless, and requires no maintenance. It is permanently
sealed and has no user serviceable parts.
Pump end: The pump mechanism (pump end) requires very little maintenance beyond seasonal
inspection for wear and tear. It may wear more rapidly if there are abrasive solids or chemicals in the
water source. It is best to take periodic measurement of the pump’s performance. If the flow rate is
less than normal, a worn pump end can easily be replaced (HR models only) with the spare rotor and
stator supplied (
see end of this section for details
).
Water lock: All rubber compounds absorb water at different rates, this is advantageous to helical
rotor pumps as it helps to create a close fitting union between the rotor and stator. Under normal
operating conditions the rotor pushes excess water out of the rubber, preventing over absorption.
If however the pump is turned off (winter months) or is run too slow, then the stator will swell and
stop the rotor from turning. This is a problem seen in all brands and types of helical rotor pumps and
can be easily avoided. All HR pumps should be run every day or removed from the water when not
used.
Solar array: The solar array will require no maintenance beyond a visual inspection, especially after a
storm or strong winds over an extended period. Tighten any loose bolts and ensure the footing
remains sturdy and no erosion has undermined the frame.
Solar Tracker: If the system uses a solar tracker, periodically check mounting bolts and mechanisms
for wear and tear, lubricate if needed and ensure the array is moving freely.
Sun exposure: Cut away any vegetation that will grow enough to shade the panels. Shading even a
small corner of the solar array may stop the pump, or greatly reduce its flow. As the sun moves
closer to the horizon during winter, shadows become longer. Check at different times of the day for
shading from nearby trees and prune as needed.
Solar array cleaning: If there is dirt, mineral deposits, bird droppings or other debris stuck to the
solar array surface, clean it with water, vinegar or glass cleaner.
Power wiring: Inspect wires and connections carefully for breaks or corrosion. Any wires that are
hanging loose should be secured to prevent them from swinging in the wind or being chewed by
livestock or birds. Protect any cabling on the ground from being stood on by livestock or driven over
by cars. In the case of a tracking array, look carefully for any wire damage due to rubbing, bending,
or pulling as the tracker swings.
