Nocchi Biox-XS

Summary

Product identification

NOCCHI BIOX XS series electric submersible vortex pumps are designed for sewage works. They are constructed entirely from AISI 304 stainless steel and operate fully immersed in the pumped liquid, which provides motor cooling. The pumps feature a retracted impeller and vortex operation. Automatic versions are equipped with a float switch.

Applications

• Lifting and draining waste water with suspended solid bodies.
• Lifting stations with one or more pumps for agricultural and civil complexes.
• Draining off infiltration water.
• Handling of sewage water (hygiene facilities), emptying of cess pits, and drainage into sewage works.

Operating limits

• Maximum liquid temperature: 40°C
• Maximum immersion below water level: 7 m
• Free transit of solid bodies: 40 mm
