DESMI ROTAN® HD Heavy-duty pump Gear Pumps
DESMI ROTAN® HD Heavy-duty pump Gear Pumps 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.
Widely suitable for cast iron pumps with non-corrosive media of various viscosity.
HD pumps are designed for demanding applications, including high viscosity media.
HD pumps are known for their sturdy and simple construction. A 90° inlet and outlet structure can be provided.

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.
