Engineering review before quotation — always

Tell us
what you're
trying to seal.

Equipment, conditions, existing seal — send what you have. We check fit before we quote. The right seal starts with the right questions.

* Limits are combinatorial. 150 bar at 25°C ≠ 150 bar at 300°C. We check the intersection, not the brochure max.

How to start — pick your entry

Four ways in. One honest
path out.

Most sites make you hunt. We let you start where you are — seal, equipment, industry, or “I have a photo.”
01
I know the seal
Product code or cross-reference
Type 1, 21, M74D? Burgmann, John Crane ref? Paste it. We map to Pressivon equivalent and check face/elastomer match.

02
I know the equipment
Pump, agitator, mixer
KSB, Grundfos, Sulzer, Alfa Laval? Tell us model. We start from shaft size and box dimensions, not catalog guess.
Explore applications
03
I know the industry
Oil, chemical, water, power
Media matters. Crude vs. slurry vs. CIP acid changes everything. Start with operating environment.
Explore 9 industries
04
I don't know
Photo, drawing, old seal
Send whatever you have. We'll reverse the spec and ask only what matters. No form marathon.

Why we exist — the differentiator

The seal is only
part of the equation.

Anyone can ship a catalog number. We map equipment → conditions → existing reference → configuration before we quote. That's why returns are rare.

What breaks a seal in real life
  • — Wrong elastomer for media, not wrong size
  • — Box pressure ≠ system pressure
  • — Flush plan missing, faces run dry
01 — Equipment
Pump / Mixer / Agitator / Rotating
02 — Conditions
Pressure / Temp / Speed / Media
03 — Reference

06 — Solution
Recommended seal + alternatives
Outcome: matched seal
Sales checks completeness in <4h. If photo blurry, we ask for scale.
Engineering checks fit: materials, speed, box. Not just price match.
Only then: quotation with alternatives if needed.
The CENTERED principle

Choosing a seal isn't a catalog exercise.

The right seal depends on the equipment, the operating environment, the existing configuration and the details that aren't always visible from a part number alone.

We built Pressivon around that reality. Engineering first, catalog second.

Centered — 4 checks
✓
Centered on equipment
Shaft, box, speed — not just model name
✓
Centered on conditions
Pressure, temp, media — the killer details
✓
Centered on reference
We reverse-engineer, not just cross-ref
✓
Centered on honesty
If we can’t seal it, we say so
Full CENTERED / The Right One experience lives on /about — not crammed here.

Have an existing seal?
Don't know the exact replacement? That's okay.

Built for demanding applications

We start from equipment,
not catalog.

Pumps ≠ agitators. Sealing a bottom-entry agitator at 2 bar is different from a high-speed pump at 40 bar. We ask equipment first.

Media changes everything.

Water
Clean, waste, slurry variants
Hot oil
