STN series single-stage magnetic drive centrifugal
pumps are the close-coupled type with injection-moulded thermoplastic components (PP-GF or PVDF). The rare-earth magnets - Neodymium-Iron -Boron - offer a compact coupling that is efficient even with high-density liquids. The use of rotary PTFE/Carbographite and static PTFE/Ceramic bushings guarantees excellent value for money.

On the other hand, the pure Silicon Carbide version allows use with liquids containing suspended solids (within the limits prescribed in the table) or particularly corrosive acids.

Motion is transmitted by magnetic couplings, thus avoiding a mechanical connection between impeller and the driving part. This system guarantees maximum safety, reducing the risk of leakage to a minimum. Furthermore, the elimination of external transmission parts makes this series extremely compact, silent and safe even for inexperienced operators.
