Magnetic sealless pump
The ROTOS series offers high-performance, sealless magnetically driven pumps designed for total fluid containment. These pumps are available in both metallic alloys (AISI 316L, Hastelloy) and non-metallic materials, and utilize regenerative turbine, rotary vane and centrifugal designs to eliminate leakage.
- Material integrity: Standard AISI 316L stainless steel (fully machined); exotic alloys such as Hastelloy C available upon request.
- Standards: Built to PN 16 pressure ratings with models from 1.5 x 6 to 2.5 x 9.
- Connection: Standard threaded nozzles with flange options available.
- Global support: Supported by an international network of factory-trained distributors for engineering, system design and field troubleshooting.
