Long Coupled-End Suction Pump: The NK Range

The NK Range of Long Coupled-End Suction Pumps is engineered for industry-leading efficiency and reliability, designed to comply with future energy efficiency regulations. Featuring a back pull-out design and a hard-faced seal, these pumps ensure easy maintenance and reduced annual service costs.

Key Features

• Durable Base Frame: Provides lasting alignment for motors up to 55 kW, supporting both grouted and non-grouted installations.
• Loose Flange Design: Available in PN16/PN25, this design promotes quick installation and minimizes flange leaks.
• Self-Venting Centerline Discharge: Allows for compact piping configurations, enhancing installation efficiency.

Efficiency & Reliability

• Advanced Efficiency: Utilizing Computational Fluid Dynamics (CFD), the NK Range offers superior performance. Standard IE3 motors can be upgraded to IE4, maximizing ROI and lowering energy costs.
• Hard-Faced Seal: The silicon carbide seal endures harsh conditions, extending the pump's lifespan.
• Optimized Impeller Design: Stainless-steel impellers enhance efficiency, reduce NPSH, and minimize noise and vibration, with larger models featuring dual-volute designs.
