Parr Magnetic Drives Preface Description The principle operation of Parr magnetic drives provides for attaching the stirrer shaft to an inner set of magnets. This inner assembly is then surrounded by the drive housing that seals to the reactor head allowing pressurization without leakage. A second set of magnets is then mounted around the sealed housing. The outer magnetic assembly is then coupled to a motor drive system to provide rotation.
Parr Magnetic Drives Servicing the Magnetic Drive All non-wetted rotating parts in Parr magnetic drives are permanently lubricated and do not require servicing during normal operation. During operation, inspect the magnetic drive for unusual noise or leakage. If problems are encountered with these items take corrective action. The magnetic drive has internal bearings and thrust washers which require replacement over time due to physical wear.
Parr Magnetic Drives When replacing the bushings in the magnetic drive housing, slide the parts into place carefully and be sure to separate the two lower bushings with a spacer. A specially designed bushing insertion tool is available for this operation (See Page 8).
Parr Magnetic Drives Removing and Installing Magnetic Drives with Flat Gasket Seals These magnetic drive assemblies can be removed from the vessel head using the appropriate pin spanner wrench furnished with the apparatus (See Table on Page 8). First, unscrew the stirrer shaft from the inner rotor, then insert the pin spanner into one of the holes below the outer jacket and unscrew the drive assembly while holding the vessel head firmly.
