This article from the pump (magnetic pump and shielded pump) isolation sleeve (or shielding sleeve) thickness, isolation sleeve (or shielding sleeve) the consequences of destruction, efficiency, remote control operation, manufacturing technology and equipment, drive, noise, axial length, Coupling, bearing wear detector, the price, the normal maintenance and overhaul, the scope of application of a detailed comparison of the magnetic pump and shielded pump characteristics. Item Magnetic Pump Shield Pump Isolation Sleeve Thickness 3 times the thickness of the Shield Pump Shield Sleeve - Destruction consequences of the isolation sleeve (or shield sleeve) Medium Leakage to atmosphere Second Leak-proof sleeve (motor housing) Prevents media Leak to the atmosphere, but easy to damage the motor slightly lower efficiency of the stator slightly higher than the remote operation can not be manufacturing technology and equipment requirements lower demanding higher standard motor motor or turbine motor noise slightly larger (motor with fan) slightly smaller (motor is not With fan) longer axial length Coupling with coupling, to be corrected No coupling Bearing wear Detector is in the trial period The price is similar to the basic Near normal Maintenance Difficult to apply Scope Power (kW) / Temperature (℃) / pressure (MP) 75/100 / 1.6 200/400/40 Room temperature and pressure, easy to clean the vaporization of the medium good good at room temperature and pressure Easy to vaporize the media generally not available Specific types of media containing solid particles generally not Suitable for occasions with slightly higher solid particles, especially not suitable for iron-containing particles Specific models for medium containing solid particles (external cleaning flush Liquid) high melting point easy to crystallize media generally not suitable to have a special model strong corrosive media good not applicable (due to the shielding sleeve thickness limit)
