- Wide variety of gauge options with gauge accuracy of +/- 2% or better full deflection
- Models available with no gauge, custom fills, and factory installed instrumentation provided by customer
- NPT, BSP, socket weld, tri-clamp, flange and union inlet options
- NSF/ANSI 61 available on select models
How the SENTINEL Diaphragm Seals Work
SENTINEL Diaphragm Seals, alternatively known as gauge guards or gauge isolators, utilize a chemically resistant diaphragm to isolate and shield system instrumentation from corrosive process fluids, freezing conditions, and slurries.
Features
- Sizes from 0.25” up to 2” with multiple port options
- Offered in PVC, Polypropylene, CPVC, PVDF, and 316L Stainless Steel with additional materials available on request
- PTFE diaphragms with EPDM and Viton optional on Pressure Relief Valves
- Spring pressures 5-50 psi, 5-150 psi, 5-250 psi and 50-350 psi
- NPT, BSP, socket weld, union and flange inlet options
How the Back Pressure & Pressure Relief Valves Work
Back pressure valves optimize pump performance by maintaining continuous back pressure and doubling as anti-siphon mechanisms. Conversely, pressure relief valves safeguard pumping systems from damage due to equipment defects or line blockages by relieving excess pressure.
Features
- PVC or borosilicate glass columns with CNC precision machined end caps
- Sizes ranging from 100mL up to 20,000mL
- Sealed, removable and loose PVC end cap options
- Glass column end caps available in PVC, CPVC, Polypropylene, PVDF and 316L Stainless Steel
- NPT, BSP, union and flange connection options
How the SENTINEL Calibration Columns Work
Calibration columns are positioned along the pump's suction line, featuring a vented top connected to the supply tank or drain. Utilizing isolation valves, the column is filled with process fluid from the supply tank and subjected to a timed, one-minute test where it is drawn down. The remaining fluid in the column is then measured using the graduated scale, indicating measurements in both milliliters per minute (mL/min) and US gallons per hour (US GPH).
Features
- CNC precision machined components
- Body, quill and check disk in chemically resistant PVC, PVDF, Polypropylene or 316L Stainless Steel
- Spring-loaded check disk prevents process fluid backflow into the chemical feed and stops chemical flow when the pump is shut down
- In stock models with 0.50”, 0.75“ and 1.0” NPT connections for easy installation
- Choose from EPDM or Viton O-rings
- Custom quill lengths and connections available on request
How the SENTINEL Injection Quills Work
SENTINEL Injection Quills are engineered to distribute chemicals safely and effectively within process pipelines. They enable direct and uniform injection of chemicals into the heart of the process flow, away from the pipe walls and where flow velocity is at its peak. By injecting chemicals directly into the flow's center, contact with pipe walls is minimized, promoting more consistent mixing with the process fluid.
