Product catalog summary

Specifications:
The pump casing features suction and delivery connections with the same diameter and on the same axis (in-line). The materials used include cast iron for the pump casing, and stainless steel for both the impeller and shaft.

Applications:
Suitable for clean liquids without abrasives and non-aggressive to pump materials, with solid content up to 0.2%. Ideal for heating, conditioning, cooling, and circulation plants, as well as civil and industrial applications where low noise is required.

Operating Conditions:
Liquid temperature ranges from -10 °C to +120 °C, with short-term duty up to +140 °C. Ambient temperature can reach up to 40 °C. The maximum glycol content is 50%, with mixtures over 20% requiring rechecking of pumping data. The maximum permissible working pressure is 6/10 bar.

Motor:
The pump is equipped with a 2-4-pole induction motor, 50 Hz, with three adjustable speeds. It is available in three-phase (230V or 400V) and single-phase (230V) versions, with insulation class H and protection IP 43.

Operation:
The pump can operate in single or parallel modes, with a twin pump version available. The operation can be customized by the customer, with one pump on standby.

Installation:
The pump features a double operation capability, allowing for parallel operation of two pumps or single operation as chosen by the customer.

Performance and Dimensions:
The document includes detailed performance curves, dimensions, and weights for various models, such as NCD 40, NCD 50, NCD 65, and NCD 80, with specific data on flow rates, head, and power consumption.

Compliance:
Tolerances are in accordance with UNI EN ISO 9906:2012 standards.

Limitations:
The product cannot be sold in the EU.
