Key Benefits & Applications
-
Reliable Pump Control
Maintains system pressure by switching pumps on/off in the 60–80 psi band, ideal for well, booster, or pump stations. -
Built for Water Service
Designed for use with potable or fresh water systems, with materials resistant to corrosion and fluid compatibility. -
Precision & Stability
Snap-action contacts and tight repeatability (±3%) ensure consistent performance over many cycles. -
Compact & Easy to Install
¼″ internal port, screw clamp terminals, and a compact housing make integration into control panels or pump systems straightforward. -
Standards-Compliant Safety & Quality
Holds certifications like UL 508, CE, and NSF, assuring quality in regulated applications.
Installation & Usage Tips
- Mounting Position: It may be installed in any orientation, but avoid mounting with diaphragm facing downward if particulate materials are present.
- Piping & Plumbing: Use ¼″ NPSF female coupling; ensure clean threads, use appropriate thread sealant.
- Electrical Wiring: Use appropriate gauge wire, tighten screw clamps securely but avoid over-torquing.
- Adjustment (if needed): Only adjust within manufacturer’s limits. Do not set beyond safe operating pressures.
- Regular Inspection: Periodically check for corrosion, diaphragm wear, or contact degradation, especially in water applications.
