Blacoh - Sentinel Diaphragm Seals

Blacoh - Sentinel Diaphragm Seals

Features & Specifications:

Our SENTINEL Diaphragm Seals protect and isolate all forms of system instrumentation from hazardous and corrosive process fluids… unconditionally guaranteed!

Isolate and Protect Process System Instrumentation

Without proper protection, process fluids regularly contaminate and damage in-line system instrumentation. The strength and durability of SENTINEL diaphragm seals isolate and protect all forms of system instrumentation from the hazards of corrosive process fluids.

  • Protect gauges and other system instrumentation from process fluid contamination and corrosion
  • Accurately transfer process pressure without direct contact with process fluids
  • Prevent erratic surges and clogging due to solids in process fluids
  • Protect gauges from freezing and slurries
  • Ensure accuracy and reliability of pressure instrumentation when working with corrosive or solids-laden fluids
  • Reduce costs by replacing expensive gauges with low-cost utility gauges

Unconditionally Guaranteed

  • SENTINEL Diaphragm Seal housings are unconditionally guaranteed for life not to fail or we’ll replace them at absolutely no cost to you.

Features & Benefits

Diaphragm Seals, also referred to as ‘gauge guards', employ a chemically resistant diaphragm to effectively isolate process fluids from gauges and other system instrumentation. The durable diaphragm allows SENTINEL to accurately transfer process fluid without direct contact with hazardous or corrosive process fluids.
