Vulcan Seals Type 8DIN
Technical Data Sheet
A highly proficient, widely utilised, ‘O’-ring mounted, shaft directional dependent, conical spring mechanical seal. jj
Supplied as standard with a solid Stainless Steel head and a Carbon Type 12 stationary seat to suit non-DIN housing dimensions.
The head is an inserted design if a Carbide face is specified; all stationaries are monolithic.

The PV chart shows the maximum operating pressuresof this Vulcan seal type based on the seal face materialsused. Different lines on the chart indicate different materialcombinations, as shown underneath.
It also assumes stable operation in a clean, cool, lubricatingand non-volatile fluid with an adequate flush rate.
For more in-depth pressure rating calculations based onspecific material combinations and application conditions,please consult us.
Stainless Steel vs Carbon | x 0.30 |
A. Shaft size: 1” therefore pressure is 12 bar (from PV chart)
B. Media: Water (multiplier = 0.85)
C. Temperature: 50°C (multiplier = 1.00)
D. Speed: 1450 rpm (multiplier = 1.00)E. Face combination: Stainless Steel vs Carbon (multiplier = 0.30)
For this particular Type 12 seal size, the calculation for the approximate guidance maximum operating pressure would be:
A x B x C x D x E12 bar x 0.85 x 1.00 x 1.00 x 0.30 = 3.06 bar
Please note that due to the many operational andapplication variables that affect seal performance, theinformation given on this page is for guidance only.
We therefore strongly recommend careful individualtesting and monitoring of all seals and related equipmentfor any proposed application.Our policy is one of continuous technical and efficiencyimprovement.
As such, all specifications may be subjectto change without prior notice.
