Maximum Operating Pressure

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.

Example Calculation for Vulcan Seals Type 8DIN

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
