Maintenance
Excessive wear to the pump can result in driven magnet rub on the
magnet cup. This can generate high surface temperatures or degrade the
capability of the pressure boundary. Remove the pump from service and
replace or repair if pump performance degrades significantly or the pump
becomes noisy.
Ensure that heavy deposits of dust are not allowed to accumulate. Clean
the pump periodically.
The pump cannot be drained completely, a certain amount of liquid will
remain in the magnet cup area. Ensure that the pump is either flushed
with a suitable flushing agent or precautions are taken against the effect
of any remaining liquid during servicing. When the pump has been
handling flammable, toxic or hazardous fluid, the pump internals must
be properly decontaminated by suitably qualified personnel. The Material
Safety Data Sheet for the pumped liquid must be referred to for correct
procedures and precautions to be followed when handling the liquid.
Micropump EagleDrive motors are designed to be maintenance free and require no
adjustments. To ensure the motor or pump/motor assembly retains optimum performance
maintain the fluid circuit to keep filters clean and prevent abrasive solids from passing
through the pump.
A program that includes periodic monitoring of your Micropump product is
recommended to provide timely detection and assessment of any problem.
NOTE
Magnet Decoupling
The EagleDrive pump/motor combinations do not decouple. If pump load becomes
excessive, current limiting in the controller prevents motor overload. Additional protection
is provided by a thermal sensor which shuts down the drive if the internal temperature
exceeds a preset value.
