DESMI  ROTAN® ED - Environmentally friendly magnetic drive pump

Desmi ROTAN® is the world's leading manufacturer of internal gear 

pumps. ROTAN® internal gear pumps provide favorable flow conditions as the fluid flow direction 

changes only require a slight adjustment to the pump.

DESMI  ROTAN® ED - Environmentally friendly magnetic drive pump

Environmentally friendly magnetic drive pumps that completely solve the leakage problem, 

especially in working conditions where liquid or gas leakage is not allowed.

Due to the minimal maintenance required, ED pumps are a very economical solution compared

 to traditional sealed pumps. Especially in applications where double mechanical seals are required. 

Usually, the application conditions of different working conditions are also different, which requires 

sealing and auxiliary flushing systems, and frequent maintenance or replacement. Therefore, the life 

cycle cost of ED pumps is usually much lower than that of double mechanical seals.

DESMI specializes in the development, manufacturing, sales and services of pump and 

pumping solutions, including a variety of environmental equipment for oil spill recovery, 

seaweed and waterway cleaning.

DESMI specializes in liquid delivery and has a wide range of applications in the process industry.

Industrial pumping solutions include ROTAN® internal gear pumps and efficient DESMI 

centrifugal pumps.

DESMI provides efficient and reliable pump solutions for all utility applications.

To better serve cities, buildings and residents, our primary belief is reliability, energy 

optimization and friendly service of equipment operations.

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.
