NM, NMS 60 Hz

Product catalog summary

Specifications:
The document outlines the specifications for the NM and NMS series of close-coupled centrifugal pumps with flanged connections, operating at 60 Hz. These pumps are designed for clean, non-abrasive liquids and are suitable for applications such as water supply, heating, cooling, and fire fighting. They feature a pump casing made of cast iron or bronze and a 2-pole induction motor with insulation class F and protection ratings of IP 54 or IP 55.

Construction:
The pumps are constructed with an electric motor directly connected to the pump, supporting power up to 22 kW. For motors ranging from 30 to 75 kW, a stub-shaft construction with an integrated thrust bearing is used. The pump casing features axial suction and radial delivery, adhering to EN 733 standards.

Materials:
The NM and NMS pumps use cast iron for both the pump casing and impeller, while the B-NM and B-NMS versions use bronze. Shaft materials vary from AISI 303 to AISI 316 depending on the power rating.

Operating Conditions:
The pumps are designed to operate with liquid temperatures ranging from -10 °C to +90 °C and ambient temperatures up to 40 °C. They can handle a total suction lift of up to 7 meters and a maximum working pressure of 10 bar, with some models supporting up to 16 bar.

Motor:
The motor is a three-phase induction type, compatible with frequency converters, supporting various voltages, and classified under IE3 efficiency for motors from 0.75 kW.

Applications:
These pumps are ideal for civil and industrial applications, including irrigation and fire protection systems. They are also suitable for heating, air conditioning, and circulation systems.

Special Features:
On request, the pumps can be equipped with special mechanical seals, different voltage options, and additional protections such as IP 55. They can also be adapted for environments with higher or lower temperatures.

Pumps with Frequency Converter:
The NM EI pumps, available from 0.55 kW to 22 kW, include an I-MAT frequency converter for variable-speed operation, enhancing energy efficiency and system adaptability. They offer protection against dry running, closed valve operations, system leakages, and electrical imbalances.

Operating Modes:
The pumps can operate in various modes such as constant pressure, proportional pressure, constant flow, fixed speed, and constant temperature, each mode utilizing specific sensors to maintain desired system parameters.
