Schmierer Diaphragm Seals

SSEAdiaphragmseals

Diaphragm seals are used to protect pressure instruments from corrosive, viscous, clogging or hot process media and safeguard highly hygienic and ultra pure liquids from contamination.The seals and membranes are customized for a variety of applications with different materials, coatings and linings, mounting and connection types.

The pressure will be transmitted without any time delay from the highly flexible and sensitive seal membrane to the measuring instrument using a transmission fluid.

Schmierer Seals are manufactured under highest quality standards with selected materials and coatings, (elastomers, rubbers, high grading stainless steels, Hastelloy, Monel, Inconel, Tantalum, Titanium) for customer specific requirements on process media, pressure, temperature and mounting positions. The connecting part can be made or protected (lined) with suitable material, i.e. SS 316L, PP, PVC, PVDF etc. They will run through several test cycles on tightness and shape of the surface.

The variety of mounting and connection types (flange,sandwich, threaded, tri-clamp, inline, flush, extended, capillary...) make it suitable

Schmierer Diaphragm Seals for pressure instruments

  • for corrosive, aggressive media (Chemical, Petro-Chemical)
  • for toxic and hazardous media (Acid and Alkaline)
  • for f&b, sanitary, hygienic and aseptic applications
  • for viscous, crystalizing, polymerizing media (Palm Oil, Oleo Chemical)
  • for non-homogenous media with particles (Paper & Pulp)
  • for ultra pure process fluids (Semiconductor, Solar)
  • for high temperature and pressure procedures


With our special diaphragm seal filling station Schmierer diaphragm seals can be locally connected in Shah Alam to pressure gauges, switches and transmitters and DP instruments of all brands.
