Mixer shaft seals

Shaft Seals

Marion Has Four Styles Of Shaft Seals. Clean-Ability and Maintenance Requirements Will Determine the Appropriate Seal Selection.

A machined, barrel housing is welded to the mixer end plate
A seal washer and woven packing rings are used
The adjustable packing gland is field tightened to accommodate packing wear
Optional air-purge is available to prevent migration of material along the shaft
Ideal for most applications with periodic maintenance requirements
Machined seal housing equipped with threaded air purge connection
Standard on all chopper shaft applications

Machined seal housing is designed for quick disassembly and clean-out
Adjustable "finger knobs" allow maintenance without the use of tools
TFE/ synthetic or "food grade" Teflon packing materials are used
Machined seal plate is attached to the mixer end plate with no exposed cracks or crevices
Optional air purge is available to prevent migration of materials along the shaft
Ideal for sanitary applications where frequent cleaning is required
Machined mounting plate creates sanitary interface with mixer
Food grade packing materials are available

Seals use mechanical interference of machined parts to prevent migration of material along the shaft
Air or liquid purge options are available
Once installed and adjusted, mechanical seals require less periodic maintenance
Mechanical seals are designed to accommodate greater amounts of shaft run-out
Ideal for liquid or pressure applications
Precision machined components
Reduces shaft wear

Cast iron seal housings are through-bolted on either side of the mixer end plate
The housings are machined to accept either felt or packing rings
An oil or grease lubricant port is piped to the exterior of the mixer
This rugged seal design is well suited for abrasive environments with dry materials
Single or double seal designs
