Since Danish imported water pumps require very little maintenance, ED pumps are a

 fairly economical solution compared to traditional sealed pumps. Especially in applications 

where dual mechanical seals are required. Usually, the application conditions of different 

working conditions are different, which requires sealing and auxiliary flushing systems, 

and requires frequent maintenance or replacement. Therefore, the life cycle cost of ED 

pumps is generally much lower than that of dual mechanical seals.
