NCED G F

Product catalog summary

Designation and Series: The document describes the NCE D G 40 F - 120 / 250 series of energy-saving twin circulating pumps with flanges. These pumps are designed for heating, conditioning, and circulating systems in both civil and industrial applications.

Construction and Features: The pumps are equipped with a variable speed circulating pump driven by a permanent magnet synchronous motor, controlled by an onboard inverter. They feature DN ports with flanges and a maximum head of 120 dm. The pumps are designed for energy efficiency with an Energy Efficiency Index (EEI) ≤ 0.20.

Operating Conditions: The pumps operate within a liquid temperature range of -10 °C to +110 °C and an ambient temperature range of 0 °C to +40 °C. They can handle a maximum working pressure of 6/10 bar and are certified to meet CE requirements. The sound pressure level is ≤ 54 dB(A), and they can accommodate a maximum glycol quantity of 20%.

Motor Specifications: The pumps use a synchronous motor with permanent magnets, offering variable speed operation. They operate on a single-phase 230 V power supply with a frequency of 50-60 Hz. The motor is protected to IP 44 standards and has an insulation class of H.

Smart Pump Features: The NCED G.F pumps adapt their functions to the system by measuring pressure and flow, adjusting speed accordingly. They offer multiple operating modes, including automatic, proportional pressure, constant pressure, and fixed speed modes. A night mode is also available.

Operating Modes: The automatic mode is factory-set and adjusts operating pressure based on the hydraulic system. Proportional pressure mode adjusts pressure proportionally to flow, while constant pressure mode maintains pressure despite flow changes. Fixed speed mode allows operation at a constant curve.

Characteristic Curves: The document includes characteristic curves for various models, illustrating performance metrics such as flow rate (Q m³/h), head (H m), and power consumption (P W).

Dimensions and Materials: The document provides detailed dimensions and weights for different pump models. Key materials include cast iron for the pump casing, stainless steel for the impeller and shaft, carbon for bearings, and EPDM for gaskets.

Energy saving twin circulating pumps with flanges Operating modes Automatic mode (factory setting): In this mode the pump automatically sets the operating pressure, depending on the hydraulic system. This mode is recommended in most systems. Proportional pressure mode: The circulator changes the pressure propotionally to the current flow. The pressure value can be adjusted with the + and - buttons. Constant pressure mode: The circulator mantains the pressure constant when the reference flow changes. The pressure value can be adjusted with the + and - buttons. Operating mode-control panel Fixed...
