Compact Gauge Guards / Diaphragm Seals / Instrument Isolators Series GGME

Compact Gauge Guards / Diaphragm Seals / Instrument Isolators Series GGME

  • Polypropylene bodies for excellent chemical compatibility and temperatures to 185° F (85° C). The upper half (instrument side) is glass-filled polypropylene; the lower half (process side) is 100% natural, unpigmented virgin polypropylene.
  • Available with or without gauge (dual in PSI and bar). When ordered with gauge, an economical 2″ black steel case with brass connection is standard.
  • Increase product reliability and reduce system downtime caused by failure of instruments not isolated by seals.
  • Compact size makes these isolators ideal for limited space installations.
  • Exceptionally low unit cost – now makes it feasible to protect even moderate priced instruments.
  • Compact size makes these isolators ideal for limited-space installations.
  • Liquid pressures to 200 PSI with ±4% accuracy. Choice of Buna-N or FKM (Viton) seal will handle most applications.
  • Use with gauges, transducers, and pressure switches.
  • Simple to fill and install.
  • Hermetically-sealed uni-body construction – molded body avoids possibility of dangerous leaks.
  • For use with highly aggressive or ultra-pure liquids.
  • Diaphragm safety – If the gauge or instrument fractures or is removed from the guard while the system is pressurized, the diaphragm will automatically seal against leakage to the atmosphere.

Dimensions:

When ordered with gauge, factory supplied gauge face size is 2″.
