metal magnetic coupling chemical pump. Sealed design, no mechanical seal. Leak-proof magnetic drive pumps are ideal for toxic and hazardous liquids. Major service industries include chemical, petrochemical, pharmaceutical and electroplating applications.
Corrosion resistant chemical pump.
Threaded pump (standard version) or with flange (on request).
Samarium cobalt (SmCo) permanent magnets.
The opposing magnets are encapsulated in a corrosion-resistant plastic.
Also suitable for explosive atmospheres (specific models available on request).
Only for cleaning liquids that do not contain solids (especially metallic liquids).
there is no dynamic seal and magnetic coupling between the pump and the motor, which at least actually prevents external leakage. However, their maintenance is usually more expensive than pumps with mechanical seals.
an external magnet connected to the motor shaft transfers motion to an internal magnet connected to the impeller. Since the motor shaft does not extend into the pump body, the non-contact magnetic pump is encapsulated and protected from corrosion.
the thin plastic coating of the magnet and the closed channel of the impeller cannot withstand liquids containing abrasive solids and suspended particles, especially metal liquids. The supersaturated liquid may also cause problems for the magnetic pump.
in the metal magnetic pump, the pump body and impeller are made of AISI 316 (standard version). Bushing: Charged PTFE or graphite. O-ring: EPDM or FPM. Shaft: Hastelloy C- 276. Materials of construction available upon request: Hastelloy and Titanium.
magnetic pumps are considered to be sealed pumps. Its presumed tightness must be carefully evaluated in the light of the characteristics of the pumped liquid. The choice of magnetic drive pump may be affected by incorrect installation habits rather than actual technical requirements. Magnetically coupled pumps are usually more popular than mechanical seal pumps because people believe that the former is safer, but the use of magnetically coupled pumps requires special attention to specific working conditions.
