HL 962.04 Standard Chemicals Pump with Magnetic Clutch
Education / GUNT Hamburg / Mechatronics / Maintenance /

Magnetic drive pumps are used primarily in process engineering to pump aggressive, toxic and flammable liquids.

  HL 962.04 is a fully self-contained centrifugal pump with no shaft seal. It is fitted with a permanent-magnetic synchronous drive complete with clutch. Its design means it is entirely sealed tight. As a result, magnetic drive pumps are often chosen to pump highly corrosive liquids. Leakage of such liquids could result in major problems.

  The viscosity of the delivered liquid is a key criterion in selecting a pump, as it determines the coupling torque to be transmitted. The torques transmitted by magnetic couplings are limited. As a result, magnetic drive pumps are not suitable for all operating conditions and media.
