Lead-On Chamfer
For ease of installation, the lead-on edge of the shaft or sleeve should be
chamfered as shown.

Checking the Equipment
Successful operation and life of this seal is dependent on acceptable equipment
dimensions, alignments, and finishes. Before installation of the seal, the following
checks should be made with respect to the seal housing and the shaft, especially
(where marked
†)
at the seal position. The usual equipment to measure these fea-
tures would include a micrometer and dial indicator.
Shaft/Sleeve Outside Diameter
†
Refer to Dimension Tables
Shaft/Sleeve Finish
†
0.2 to 1.2 µm Ra
Shaft/Sleeve Ovality/Out-of-Roundness
†
< 0.05 mm / 0.002 in.
Shaft End Play/Axial Float ± 1.60 mm / 0.063 in.
Shaft/Sleeve Run-Out
†
< 3.81 mm / 0.150 in. F.I.M.
Shaft/Sleeve Lead-On Refer to Lead-On Chamfer
Seal Housing End Face Squareness < 0.80 mm / 0.031 in. F.I.M.
to Shaft/Sleeve
NOTE: If the measured dimensions exceed the values given, correct the equipment
to meet the specifications before installing the seal. If the seal is installed on
a sleeve, the sleeve must be liquid- and pressure-tight through its bore. The
thickness of the gland plate must be sufficient to retain the service pressure
without distortion.
Operating Conditions
The Type 32 is an elastomer O-ring, multiple spring, hydraulically balanced, dry running
seal supplied in metric and inch sizes for outside mounting.
These instructions apply to the seal as installed in a top entry mixer, agitator,
or reactor vessel, in accordance with the application information contained in
the John Crane technical document S-32-E, and any John Crane seal selection litera-
ture or process. Typical operating limits are shown below.
The selection of materials used in the construction of a seal should be made with
regard to their temperature and chemical resistance/compatibility with the product.
Temperature Limits:
_
45°C to +150°C /
_
50°F to +300°F
(Depending on the materials used.)
Pressure Limits: Full vacuum to 15 bar g / 225 psig (refer to PV graph)
Speed Limits: Up to 2 m/s / 400 fpm
