Diaphragm Seal Filling Station Shah Alam

Schmierer SEA Sdn. Bhd. has set up a Diaphragm Seal Filling Station in Shah Alam in June 2017. With this service we will be able to locally assemble standard and specialized diaphragm seals (DS) to a wide range of pressure instruments from all major brands in manufacturing plants in South East Asia.

Diadsphragm Seals can be connected to

  • new pressure transmitters, switches and gauges of locally available models, brands and manufacturers to significantly shorten the delivery cycles for customized applications
  • used pressure instruments with defect diaphragm seals. The DS replacement saves cost and reduces the down time of machines and plants. It provides valuable information regarding the process which lead to better choice of diaphragm seal material for an increased lifetime.

How does a Diaphragm Seal Filling Station work?


fillingstationDiaphragm seals are directly mounted to Bourdon Tube gauges, pressure switches and transmitters or connected by a capillary filled with a silicon oil liquid.
When pressure is applied to the diaphragm membrane the filling liquid is hydraulically transmitted to the sensing unit.
Contained trapped gases or air in the filling fluid will cause incorrect readings with rising temperatures.

In the degasing process of a filling station a powerful vacuum pump extracts gases and moisture and creates a vacuum in the airspace of the capillary. The filling liquid is drawn into this space by the vacuum and then sealed in.

Schmierer SEA offers a selection of Diaphragm Seals for:

  • special chemical applications (contamination, aggressive, hazardous media)
  • hygienic and sanitary applications for Food and Pharma
  • high temperature and pressure applications

The functionality and accuracy of the Diaphragm seal is tested and authorized by a certificate of factory filling and calibration.


  • Shorter delivery cycles:
    delivery times of 4 weeks as compared to 3-4 months for orders of branded instruments with customized flanged DS
  • Modular setup:
    a wide range of DS types can be attached to the instrument/manufacturer of your choice
  • Cost-effective repair:
    savings up to 50% by replacing the damaged DS instead of buying a new transmitter
  • Reduced down times of machines and plants due to DS failure
