Grout & Concrete Diaphragm Seals

Monitoring pressure in lines carrying structural grout, wet concrete, raw sewage, or thick waste fats is notoriously difficult for standard instrumentation. These high-viscosity fluids and dense, suspended solids can instantly clog, score, or destroy standard metal sensor faces. Our heavy-duty Grout & Concrete Seals are engineered specifically to overcome these brutal processing environments, acting as a rugged physical barrier that ensures continuous, trouble-free pressure readings.

Abrasion-Resistant Composite Design

By combining high-strength metal housings with ultra-flexible polymer technology, these seals offer exceptional resilience against abrasive media:

• Flexible PVC Diaphragm: Utilises a tough, chemical- and wear-resistant PVC diaphragm. This highly flexible material is uniquely suited for absorbing the heavy impact of grit, aggregate, and sludge without puncturing or fatiguing.
• Robust Connection Housing: The main seal body is available in heavy-duty industrial brass or premium AISI 316L stainless steel depending on your system’s corrosion requirements.
• Standard Fittings: Features a rugged 1/2″ BSPT male process thread as standard and a 1/2″ BSP instrument port to accept heavy-duty mechanical pressure gauges or industrial transmitters.

Performance & Process Safety

• Extreme Pressure Envelope: Built to survive demanding high-pressure pumping systems, with an operational range spanning from 2 bar up to an impressive 400 bar maximum.
• Safe Transmission Fill: Pre-filled with standard FDA-approved non-toxic glycerine fluid, ensuring precise hydraulic pressure transfer while offering absolute process safety.
