Safety instructions for the operator
The surface temperature of the motor under full load may exceed 60°C. If
needed, this surface should be protected on site against contact in order to
avoid skin burns.
The drive should be protected against dust, water vapor condensation,
humidity, splash water, aggressive gases and liquids. Please provide for an
adequate air ventilation and thus cooling of the motor.
The micro annular gear pump mzr-4661 must not be used in areas exposed to
explosion risks or in proximity of inflammable gases and vapors.
Possible leaks of dangerous liquids (for example from the shaft sealing) should
be guided away in a way not to represent any danger for the personnel and the
environment. The pump should be regularly checked for possible leakage. All
legal requirements in this matter should be complied with.
Take care that all risks resulting from the electric energy are excluded. For
details please refer to the instructions provided by the authorities in charge or
your power supplier.
Warning
Please insure, that the totality of the liquid supply system such as tubes, hoses,
filters etc. are free from dust or dirt particles. Impurities such as metal swarf,
plastic or glass splinters may impair or damage the pump leading to its failure.
Warning
Please, operate the pump with a filter featuring 10 µm or smaller pores. It will
protect the pump.
