WIKA has released the 990.36 diaphragm seal in a special version with a diaphragm protection disc. This disc protects the seal's diaphragm against mechanical damage and abrasion.
All wetted mechanical parts are made of 316L stainless steel. The mechanical pressure gauges are also available with a rubber cover for added protection. The diaphragm seal is suitable for pressure measuring applications where the media contains hard and abrasive solids. These applications include cast plaster pumps and concrete pumps, heading and cutting machines for tunnels bores, and mining and waste removal. The 990.36 can be combined with a range of pressure gauges or pressure transmitters.
