Multistage immersion pumps type DUO are characterized by a robust and durable design and can be used in a wide variety of applications. They are ideal for pumping clean media or media with slight solids loading such as lubricants, alkaline solutions and solvents used in washing, cleaning, degreasing, pickling and phosphating. The pump series DUO can be operated with variable speed drives. Optionally, this series can be equipped with two or three pressure outlets. The use of just one motor with multiple pressure outlets for different duty points results in minimal space requirements.
