NCS3

Product catalog summary

Construction: The NCS3 circulating pumps feature a bronze pump casing with suction and delivery connections of the same diameter and on the same axis, known as in-line configuration. The pump can is made of stainless steel AISI 316. The materials used for different models include bronze for the pump casing, composite for the impeller, stainless steel or ceramic for the shaft, and graphite or ceramic for the bearings.

Applications: These pumps are designed for the circulation of sanitary hot water.

Operating Conditions: The pumps operate with liquid temperatures ranging from +5 °C to +65 °C and can withstand ambient temperatures up to 40 °C. They have a sound pressure level of ≤ 43 dB (A) and require a minimum suction pressure of 0.05 bar at 50 °C. The maximum permissible working pressure is 10 bar.

Motor Specifications: The pumps are equipped with a 2-pole induction motor operating at 50 Hz, with three adjustable speeds. The NCS3 model is single-phase with a voltage of 230 V, insulation class H, and protection class IP 44.

Special Features on Request: Brass unions are available upon request.

Designation: The designation system for the pumps includes series, DN ports in mm, max head in dm, and connection size in mm.

Characteristic Curves: The document includes coverage charts and characteristic curves for different models, illustrating the relationship between flow rate (Q) and head (H) in various units.

Dimensions and Weights: The document provides detailed dimensions and weights for different pump models, along with optional union kits for specific configurations.

Examples of Installations: The document includes examples of installations to guide users in setting up the pumps correctly.
