Nocchi Priox

Summary

Product Identification

Nocchi Priox submersible vortex pumps are designed for stationary and portable installation in waste water applications. These single-stage pumps are constructed entirely from 100% AISI 304 stainless steel. They feature a vortex impeller with a free passage of either 40 mm or 50 mm. The pumps operate fully immersed in the pumped liquid, which cools the motor. They are available in single-phase or three-phase versions, suitable for a 50 Hz power supply. Automatic versions are equipped with a float switch.

Applications

• Lifting and draining waste water with suspended solids and fibers, compliant with EN 12050-2.
• Pump stations with one or more pumps for agricultural and civil complexes.
• Drainage of flooded cellars.
• Groundwater lowering.
• Effluents from showers, washing machines, and sinks below sewer level.
• Emptying of drain wells.

Operating Limits

• Maximum liquid temperature: 40°C
