Magnetic Drive Centrifugal Pump (Metallic, sealless)

Zero leakage by construction — the mechanical seal, the most common leak point, simply does not exist.

Sealless design eliminates the mechanical seal — the most common leak point. Standard choice for solvents and hazardous media.

Where it is used

  • Toxic, flammable, expensive or environmentally sensitive fluids: solvents, acids, heat-transfer media
  • Duties where seal maintenance and seal-support systems are not wanted
  • Services where emissions rules make a packed or single-sealed pump a compliance problem

Where it stops

  • Solids are the enemy of the magnetic coupling and containment shell bearings — clean fluids only
  • Dry running damages the bearing system fast; the pump needs the liquid it moves
  • Above 250 °C the standard recommendation ends; jacketed builds extend it, at engineered-build pricing

Jacketed magnetic-drive builds are documented to about 350 °C; the recommendation zone ends at 250 °C.
