Nocchi Minivort P

Summary

Product identification

Nocchi MINIVORT P electric submersible vortex pumps are designed for continuous duty in fixed installations, specifically for sewage works. They feature a vortex operation with a retracted impeller, constructed entirely from cast iron for ruggedness and reliability.

Operating limits

• Maximum liquid temperature: 40°C
• Maximum immersion below water level: 7m
• Minimum drainage level: 45 mm (on manual version)
• Free transit of solid bodies: 52 mm

Feed water

These pumps are designed for handling:

• Waste water, slurry, and sewage
• Civil and industrial sewage with suspended solid bodies
• Emptying septic tanks and cess pits
• Lifting stations with one or more pumps for industrial and civil complexes

Electrical

• Motor: Dry motor, Protection rating IP 68, Insulation class F, Self-lubricating ball bearings.
• Rotation Speed:
  • 2850 rpm (P2 models)
  • 1450 rpm (P4 models)
• Single Phase Power Supply:
  • Permanently activated capacitor
  • Thermal cutout protection incorporated in the motor winding
  • Automatic versions include a float switch, watertight electrical panel (incorporating capacitor, thermal cutout protection, and manual/automatic switching module), and a 10 m H07 RN-F power cable.
• Three Phase Power Supply:
  • External protection to be fitted by the user
  • 10 m H07 RN-F power cable
