English
The water level may only be reduced to the upper edge of the motor. Once this minimum
level is reached, a mechanism should be used to switch the pump off as a safety measure.
Failure to comply with these instructions invalidates the given explosion protec-
tion.
Reduction of operating by LCIE
Special conditions for safe use from the point of view of EEx-protection (in accordance
with LCIE 03 ATEX 6202 X) :
- Motor completely under water at 60°C water temperature maximum operation time 5
minutes
- Motor completely out of water at 35°C water temperature maximum operation time 10
minutes
- If the fluid temperature is higher than 40°C (continuous operation), the device may not
be operated in an atmosphere likely to catch fire at a surface temperature of 135°C, in-
creased by the difference of fluid temperature and 40°C.
The motor is sealed against the pump chamber using one mechanical seal and one lip seal.
In order to ensure the pump never runs dry and no unauthorised high tem-peratures are
able to arise at the sliding surfaces, the separating chamber between the rotary mechani-
cal seals is filled with a collecting liquid, such as medical white oil or a water and glycol
mixture or simply water where the installation is frost-resistant.
The liquid is poured in when the pump is first assembled and must be topped up after all
assembly and repair work.
Filling levels: motors of ø 110: 115 ml
If this is not done, the temperature may exceed category T4!
Pumps with plastic hydraulic parts are only suitable for use in ex-areas using a "wet" in-
stallation.
Should pumps with plastic hydraulic parts be run dry, this will invalidate the ex-
plosion protection.
The customer must ensure that the pump is bled using a suitable automatic bleeding
mechanism so as to ensure that the pumping process starts as soon as the switching level
is reached. The supply to the shaft must be designed to prevent air from entering into the
pump hydraulics.
ATTENTION!
Do not use frequency converters (FC).
Ensure the pump cable does not snap during laying and that all other wires and insulation
materials do not suffer damage caused by vibrations or rubbing during operation of the
pump.
