Maintenance
Excessive wear to 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.
Draining
The pump should only require draining prior to disassembly for cleaning, service,
changing the type of liquid being pumped, or to prevent frozen liquid damage.
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 products are designed to be maintenance free and, apart from bypass
models, require no adjustments. To ensure optimum performance maintain the fluid
circuit to keep filters clean and prevent abrasive solids from passing through the
product.
Service
Like all pumps, Micropump products contain components that will wear over a period
of time. This will be noticeable by a gradual deterioration in performance. You should
contact your local Micropump distributor or contact Micropump directly for a service kit.
Each service kit contains full fitting and service instructions.
Excessive wear to motor can result in driving magnet rub on the magnet
cup. This can generate high surface temperatures or degrade the
capability of the pressure boundary. Ensure that the motor is serviced
or replaced in accordance with manufacturer’s guidelines. Motor hours
must not exceed manufacturer’s life specification. Remove the pump
from service and replace or repair following motor failure.
Ensure any service or replacement parts have been correctly specified,
purchased from your local Micropump distributor or Micropump directly,
and the pump has been correctly reassembled.
A program that includes periodic monitoring of your Micropump pump is
recommended to provide timely detection and assessment of any problem.
