4.3.6  Expected noise 

 

 

 

The sound pressure level of V-Series Varisco pumps with drive, as measured at the pump height at 1 m 
distance from the pump, is less than 75 dB for all models.

Accessories

 

 

Shaft coupling:   flexible coupling with / without adapter sleeve 
Touch guard:  

coupling guard 

Baseplate:  

welded fabrication, for complete (to ISO 3661) unit (pump and motor) of torsionally 
rigid design. 

 

Where complete units are delivered the coupling and the coupling guard will be 
furnished by the supplier.

5.1 

Safety regulations

 

 

Equipment operated in  potentially  explosive atmospheres must comply with relevant explosion 
protection regulations. This requirement is clear from the rating plates of the pump and the motor. 
Persons who have a pacemaker should not be allowed in the vicinity of the strong magnetic  field 
generated by the magnetic coupling. Persons within 2 m of the pump would be risking their lives!
