NV

Chemically resistant, vertical immersion pump in sealless design, dry-run capable

In the NV series, the motor power is transmitted vertically to the pump impeller via an extended shaft. The shaft runs without any additional intermediate bearing (“cantilever” principle), contact-free and wear-free inside the casing. As standard, the NV series is sealless, but it can be equipped with a labyrinth seal or shaft seal as a vapour barrier. Immersion depths up to 800 mm. Additional suction pipe extension up to 2 m (depending on size).

Solids up to a particle size of 3 mm and 10 vol.% can be pumped with the fluid. The viscosity can be up to 150 mPa·s; the maximum fluid temperature is 95 °C, depending on the design.
