Operating limits

• Liquid Temperature: Up to 140°C
• Operating Pressure: PN16 as standard (PN25 on request up to DN50)

Feed water

The L series pumps are suitable for various applications, including heating, cooling, civil, industrial, and water supply systems.

Electrical

• Power Range: 0.37 kW up to 75 kW
• Frequency: 50 Hz and 60 Hz
• Poles: 2 and 4 pole configurations
• Motor Efficiency: IE2 and IE3 classes, compliant with Directive 2009/125/EC (ErP) – Regulation (EC) No 640/2009 and (EU) No 4/2014.
• Motor Type: Asynchronous induction with external ventilation (TEFC)
• Motor Protection: IP55
• Insulation Class: F
• VFD (Inverter) Compatibility:
  • Standard motors up to 45 kW are suitable for VFD operations.
  • Integrated inverter versions are available on the motor up to 15 kW (three-phase IVT series) and up to 2.2 kW (single-phase IVM series).
  • Single-phase versions of the pump are available up to 4 kW.
• Inverter Functions:
  • Energy saving and reduced life cycle cost (LCC).
  • Lower environmental impact and less wear of mechanical components.
  • Operation at constant differential pressure (via two transducers) or constant pressure (via standard pressure transducer).
  • Equipped with main protections (current, voltage, dry running).
  • Master/slave operation for multi-pump systems.

Mechanical / hydraulic

The pumps feature a close-coupled, in-line design for space-saving and reduced noise levels. They are manufactured with robust nodular cast iron construction.
