WDRIVE-NCL/NCLD Frequency Converted Circulation Pumps:
The WDRIVE-NCL/NCLD series is designed for high-efficiency circulation in heating, cooling, and domestic hot water systems. Each unit integrates a built-in inverter directly mounted on IE3/IE4 efficiency motors, ensuring precise speed control, energy optimization, and stable performance across varying demands.
Constructed with a cast iron body and a composite impeller, the pumps provide excellent durability and hydraulic efficiency. The monoblock shaft design without coupling minimizes mechanical losses and increases reliability. An LCD display with programmable modules offers easy configuration and monitoring of pump operation.
The series is available in single-pump (NCL) and twin-pump (NCLD) options, supporting redundancy and continuous operation where required. Standard packages include analog sensors, a safety float switch, and protection features for reliable use in demanding conditions.
Key specifications include:
- Inline flanged connections for straightforward installation.
- Operating pressure up to 10 bar.
- Temperature range from -20°C to +120°C for wide application coverage.
- Protection class IP54, 50/60 Hz, 230/400V ±10%.
- EFI ≥ 0.40, supporting energy-efficient operation.
With flow capacities ranging up to 90 m³/h and heads up to 41 meters, the WDRIVE-NCL/NCLD range offers flexibility for both residential and industrial circulation applications.
