Mechanical Seals for Process Vessels
Need a mechanical seal for a reaction vessel, pressure vessel, pharmaceutical vessel, vacuum vessel or glass-lined process vessel?
Ashish Seals India manufactures and supplies standard, custom and replacement mechanical seals for process vessels with rotating agitator or mixer shafts. Selection is based on vessel construction, shaft entry, pressure or vacuum, temperature, process medium, shaft movement and contamination limits.
Choose the vessel application below or send the equipment drawing, shaft details and operating conditions for review.
Find Mechanical Seals by Process Vessel Type
The seal must match the vessel and its agitator arrangement. Pick your vessel type below to see the details we'll need for an accurate seal recommendation.
Mechanical Seals for Reaction Vessels
Chemical and process reactions with agitation. Selected by medium, pressure, vacuum, temperature, shaft entry and speed.

Mechanical Seals for Glass-Lined Vessels
Corrosive chemical and pharmaceutical processing. Selected by vessel drawing, shaft arrangement, chemical, pressure and alignment.
View Details →Mechanical Seals for Vacuum Vessels
Processing under reduced pressure. Selected by vacuum level, product, temperature, shaft entry and leakage limit.
View Details →Information Required to Select a Process Vessel Seal
The seal must match the vessel and its agitator arrangement. Send the complete mechanical and process data rather than only the shaft size.

| Shaft arrangement | Top, bottom or side entry; diameter, speed and movement |
| Operating conditions | Normal and maximum pressure, vacuum and temperature |
| Process medium | Chemical, slurry, paste, food, pharmaceutical or other product |
| Compatibility data | Chemical name, concentration, solids and viscosity |
| Cleaning and containment | CIP, SIP, washdown, sterile or contamination-control requirement |
| Existing seal | Drawing, old sample, mounting dimensions, photographs and failure details |
Custom and Replacement Mechanical Seals for Vessels
Entry, Duty and Arrangement Review
Process vessel seals can be evaluated for top, bottom or side entry, pressure or vacuum duty, liquid-lubricated or dry-running requirements, and standard or cartridge arrangements where suitable.
Glass-Lined & Contamination-Sensitive Equipment
Glass-lined, pharmaceutical and contamination-sensitive equipment should be reviewed from the original machine drawing and material requirement before manufacturing.
Replacement & OEM Work
For replacement work, send the complete old seal, shaft and mounting dimensions, vessel conditions and product details. For OEM work, provide the assembly drawing and expected production quantity.

Frequently Asked Questions
Which mechanical seal is suitable for a process vessel?
Selection depends on vessel construction, shaft entry, diameter, speed, movement, pressure, vacuum, temperature and process medium.
Do process vessels always require an agitator seal?
A dynamic shaft seal is relevant where a rotating shaft passes through the vessel boundary. Static vessels without a shaft require different sealing products.
Can you supply seals for glass-lined vessels?
Yes. Provide the equipment drawing, shaft arrangement, chemical, pressure, temperature and existing seal details for review.
Which seal is suitable for a vacuum vessel?
The vacuum level, product, temperature, shaft arrangement and required leakage control must be checked before selection.
Can you manufacture a vessel seal from an old sample?
Yes. The old sample should be supplied with mounting dimensions and the actual process conditions.
What information is required for pharmaceutical vessels?
Provide product-contact requirements, cleaning or sterilisation cycle, materials, shaft details, pressure, vacuum and temperature.
Can you develop a custom seal for an OEM vessel?
Custom requirements can be evaluated from the vessel and agitator assembly drawing, duty and production quantity.
What affects the price of a process vessel seal?
Price depends on shaft size, arrangement, materials, pressure or vacuum, temperature, customisation and quantity.
Request a Process Vessel Seal Review
Send the vessel drawing, shaft diameter and entry, speed, pressure or vacuum, temperature, process medium and existing seal details. Ashish Seals India will review a suitable standard, custom or replacement solution.
