Nikuni TNM Seamless (Seal-Less) Magnetic Drive Pump

Description

Nikuni TNM Seamless Magnetic Drive Pump

The TNM Seamless Magnetic Drive Pump by Nikuni is a stainless steel, seal-less centrifugal pump driven by a magnetic coupling. It is designed to handle corrosive, aggressive or hard-to-seal liquids without risk of leakage. Because it lacks mechanical shaft seals, this pump offers safer, cleaner operation and lower maintenance.

How it Works

A magnetic drive pump uses two magnets: one connected to the motor shaft (outer magnet), and another inside the sealed pump chamber (inner magnet coupled to the impeller). The outer magnet drives the inner magnet through a sealed containment shell (“can”), eliminating the need for a shaft seal and preventing fluid leakage. Liquid flows through the impeller like a centrifugal pump—the difference is in the way torque is transmitted.

  • Seal-less / no mechanical seal — uses magnetic coupling instead of shaft seal to prevent leaks.

  • Stainless steel construction — corrosion resistant material for wetted parts.

  • Permanent magnetic can-type design — compact and sealed unit, suitable for demanding environments.

  • Safe with hazardous or corrosive fluids — ideal for acids, solvents, or any chemical where leak risk must be minimised.

  • Low maintenance — fewer parts that wear (no seal replacements, less risk of seal failure).

  • Efficient and reliable — good hydraulic performance; stable under load.

  • Chemical process industry (handling acids, alkalis, solvents, corrosive chemicals)

  • Food & beverage (washdown, CIP systems, chemical dosing, where leak control is critical)

  • Pharma / laboratory / biotech (high purity, sanitary or clean applications)

  • Water treatment (especially for corrosive media, or where environmental / spill safety matters)

  • Industrial cleaning systems

  • Any application where shaft‐seal leakage, fugitive emissions, or maintenance from seal wear is a concern

  • Flow and head ratings depend on model and magnet size; sizing needs to account for fluid properties (viscosity, temperature, corrosivity).

  • Material selection (e.g. SS304, SS316, or more exotic alloys) should match process fluid.

  • Suitable for continuous duty—but ensure proper support, alignment, and cooling where needed.
