SUBMERSIBLE ELECTROPUMPS KM – 4/7,5 KW

SKU: N/A Category:

KM SERIES – 2-POLE SUBMERSIBLE ELECTROPUMPS

The KM Series of 2-pole submersible electropumps is widely used in industrial, agricultural, and civil applications for draining clean water, dirty water containing suspended solids, filamentous matter, and both activated and untreated sludge.

USES

These electropumps are designed for efficient fluid drainage in a range of applications, including:

  • Industrial, agricultural, and civil wastewater management
  • Handling clean and dirty water containing suspended particles
  • Pumping filamentous matter and sludge (activated or untreated)

Important Usage Guidelines:

  • Strictly prohibited for lifting combustible fluids.
  • Do not position or remove the pump using the electric cable.
  • Maximum fluid temperature:
    • Continuous duty: 40°C
    • Intermittent duty: 80°C
  • Minimum pumping level: 20 cm above the pump body.
  • Maximum fluid density: 1,100 Kg/m³.
  • Can handle solids of a diameter that can pass through the impeller (refer to the technical chart).

CONSTRUCTION

Each component is carefully selected to ensure maximum reliability and longevity, even in demanding applications.

Material composition:

  • Motor casing, pump body, and impeller: G20 cast iron
  • Motor shaft: Stainless steel AISI 420
  • Screws: Stainless steel
  • Gaskets: Nitrile rubber (oil-resistant)
  • Bearings: Pre-lubricated and watertight
  • Seals:
    • Upper alumina/graphite mechanical seal
    • Intermediate silicon carbide mechanical seal
    • Lower lip seal
    • The intermediate and lower mechanical seals are lubricated by an oil sump
  • Impeller type: High-efficiency open single groove design
  • Pump casing: Available with DN 65 or DN 80 flanged delivery

ELECTRIC MOTOR

The 2-pole three-phase electric motor is designed for high performance and durability, ensuring efficient operation in various conditions.

Motor specifications:

  • Power range:
    • 4 kW – 230/400V, 50 Hz (direct start-up)
    • 7.5 kW – 400/690V, 50 Hz (YΔ start-up)
  • Performance stability: Maintains maximum rated power within a ±5% variation in frequency or voltage
  • Protection class: IP 68 (completely watertight)
  • Insulation class: F
  • Cooling system: Cooled by the surrounding fluid
  • Accessories included:
    • 10-metre H07 RN-F cable with free terminals
    • Three-phase protection is the user’s responsibility
    • An oil sump conductivity sensor detects the presence of lubricating liquid, ensuring the long-term reliability of the seal
