When using the pump for other media the operator is responsible for checking that the specified 
materials in the pumps are in order. In case of doubt, contact the supplier. 
 
The  noise  level  for  the  airborne  noise  appears  from  the  following  list.  The  values  indicated  are 
measured as middle values at a distance of l m from the machine surface in free field approx. 1.5 m 
above  the  base  plate.  The  sound  pressure  levels  are  general  directional  values  which  cannot  be 
regarded as guarantee values for each individual pump, as the sound level of a pump is to a large 
extent dependent on the installation method and the operating conditions. The measuring comprise 
the pump including the motor.

Environment

: 

The pumps are as a standard equipped with motors with protection class IP54, which 

means that the motor is protected against penetrating dust and that water without pressure does not 
damage the motor. The motors are dimensioned for an ambient temperature of 40°C. Pumps installed 
in explosive areas must be equipped with explosion-proof motors. The pump capacity is stamped on 
the name plate.
