Fluoroplastic-Lined Magnetic Drive Pump (sealless + lined)

Sealless containment plus a wetted path the chemistry cannot touch — for the acids that eat alloys.

Combines a PTFE/PFA wetted path with a sealless magnetic coupling. The safest mainstream answer for hazardous corrosive media.

The envelope

Recommended temperature≤ 150 °C
Delivered-evidence ceiling150 °C
SealingSealless — magnetic coupling, lined wetted path
Design basisISO 2858 envelope (lined, sealless)

Where it is used

  • Hydrochloric acid, mixed acids and other media that defeat stainless and specialty alloys
  • Corrosive and hazardous services where both containment and corrosion resistance are mandatory
  • Duties where a lined pump would do, but leakage is not acceptable

Where it stops

  • The liner sets the temperature limit: 150 °C, no exceptions offered by the construction
  • Liner damage is a rebuild, not a repair — abrasive solids and cavitation are disqualifying
  • Vacuum and suction-lift duties need an explicit liner-support statement from the manufacturer

The 150 °C liner limit is a materials fact, published consistently across manufacturers; no delivered-evidence exception exists.
