DOC No: 7046 REV G
Limits of Use
To achieve optimum performance and safe operation Micropump
products must be operated with the limits given in the Technical
Specification. Operation outside these limits is not recommended and
may result in damage to the product and/or ancillary equipment.
Temperature. Operating beyond the maximum operating temperature
given in the technical specification is not recommended and may result
in damage to the product or compromise safety by creating high surface
temperature.
Freezing. Fluid must not be allowed to freeze inside the product.
Excessive wear. Wear resulting from driven magnet rub on the magnet
cup can generate high external surface temperatures or degrade the
capability of the pressure boundary. Remove the product from service
and replace or repair if performance degrades significantly or becomes
noisy.

CAUTION
Corrosive Liquids. Corrosive liquids may eventually produce leak paths
around the sealing surfaces of the pump. The product and system piping
should be inspected for leaks on a regular basis.
Flooding and Water Immersion. The products covered by this guide are
not designed to operate immersed in water. Reference should always be
made to the installation and operating instructions for the motor under
such conditions.
Condensation. When pumping cold liquids ensure that condensation
does not present a safety hazard. Condensation on the external surfaces
of the magnet cup may result in motor seizure. Reference should always
be made to the installation and operating instructions for the motor
under such conditions.
Mechanical Danger. The product must be installed in a location that
exposes it to a low risk of external damage.
High Pressure Fluid Ejection. When operated within its technical
specification the product’s seals will prevent high pressure fluid
ejection. The system should include a pressure relief valve if the pump
is capable of exceeding the maximum system pressure.
Flammable Liquids. The fluids to be pumped should be maintained
below flash point temperature and there should be no possibility of
explosive vapors being within the product.
Hot Surfaces. Under some operating conditions, surface temperatures
can exceed 90°C (195°F.) Do not touch products while operating. Do not
touch within 30 minutes of system shutdown to allow surfaces to reach
safe handling temperature.
