Calpeda NM | NMS Close-Coupled Centrifugal Pumps:

Flanged centrifugal pumps with standard or stub-shaft motors for industrial circulation and clean water transfer.

Flow: 1 to 480 m³/h
Head: 3 to 95 m
Power: 0.25 to 75 kW

Performance:
The Calpeda NM and NMS series are close-coupled centrifugal pumps designed for clean water and process fluid handling in civil and industrial systems. NM models use an extended motor shaft, while NMS models feature a stub-shaft design with an integrated thrust bearing, allowing standard IEC motors to be used. All models include flanged connections and conform to EN 733 performance standards.

• Water supply and pressure boosting

• HVAC systems (heating, cooling, air-conditioning)

• Circulation and process water systems

• Civil and industrial installations

• Agricultural irrigation

Construction:

• NM: Extended shaft motor directly coupled

• NMS: Stub-shaft design with standard motor interface and thrust bearing
