At PCI Instruments, we are a British manufacturer of high-quality process instrumentation, specialising in a wide range of diaphragm seals. Our diaphragm seals protect your pressure measuring instruments from corrosive or toxic process media, ensuring accurate readings and longevity.
Leading global brands rely on our diaphragm seals to ensure precision and protection:
Superior Design: Our diaphragm seals are engineered with a durable, high-performance design. The inclusion of a backup diaphragm convolution helps preserve the seal’s structural integrity under overload conditions, minimizing the risk of rupture and ensuring consistent, reliable performance. Looking for a Diaphragm seal system with pressure gauge? Quality Materials: Crafted from stainless steel and other exotic metals, our seals ensure compatibility with a wide range of process fluids, including viscous and hazardous substances. Protect Your Equipment: Diaphragm seals isolate pressure instruments from harmful substances, safeguarding them from high temperatures and mechanical damage that would otherwise occur. Efficient Mechanism: The diaphragm acts as a flexible membrane that deflects under pressure, transmitting the process pressure to the measuring instrument without direct contact with the process media. This wet mechanism ensures accurate measurements even with viscous media.
We offer a wide range of hygienic ad chemical membranes to suit various applications across different industries:
Designed for processes requiring a flange connection, our flanged seals are ideal for standard process conditions. They ensure sanitary conditions, making them suitable for the pharmaceutical and beverage industries.
Featuring threaded connections for easy installation, our threaded diaphragm gaskets are compatible with a wide range of pressure measuring gauges.
Perfect for hygienic applications, our inline seals integrate directly into the process line to ensure clean conditions.
Engineered for the chemical and petrochemical industries, our chemical seals withstand aggressive chemicals and process media. Our Bolted Chemical Seal is very popular – suitable for dismounting and internal washing.
Our diaphragm seals are used in various sectors:
Our diaphragm seals combine with pressure tools to form a complete system:
Connection options include direct mounting or via a capillary tube for remote installation. The flexible capillary allows the instrument to be positioned away from the process.
Our diaphragm seals can be filled with a suitable fill fluid that transmits the pressure from the diaphragm to the device. This wet mechanism ensures accurate measurements even with viscous or hazardous media.
At PCI, we prioritise quality. Our diaphragm seals act as isolators, protecting other parts from process media that would otherwise damage them. The minimal internal volume allows them to sense changes rapidly, ensuring optimal performance in your measuring tasks.
