Pump seals, valve seals and diaphragms.
Flow-control parts
Fluid equipment sealing for pumps, valves and process equipment.
PRESIS supports fluid-control seals, diaphragms and interface parts where medium compatibility, dimensional stability and repeatable sealing performance matter.
Buyer pain points
Fluid-control projects fail when sealing behavior changes with media or cycle load.
- Media compatibility affects swelling, hardness and life.
- Diaphragm and valve parts need accurate geometry and stable movement.
- Many projects require a balance between seal force and responsiveness.
- Documentation and repeatability matter in export and maintenance supply.
PRESIS solution
Fluid equipment route
We look at the medium, pressure, temperature and operation cycle before selecting the elastomer path.
That lets the seal support the equipment rather than becoming the weak point in the fluid system.
Material and process
Fluid equipment components need medium-specific material control.
| Project need | Recommended route | Buyer questions to prepare |
|---|---|---|
| Pump seals | NBR or FKM depending on oil, fuel or heat exposure. | Medium, temperature, pressure and life target. |
| Valve diaphragms | Silicone or compounded elastomer for motion and cleanliness. | Stroke, response force, thickness and assembly fit. |
| Flow-control interface parts | Custom sealing compound with geometry matched to hardware. | Drawing, sample, media, cleaning condition and annual quantity. |
