Description
The Schneider Electric (Square D) 9037HG32LZ20 is a 2.5-inch float switch supplied without a float ball, giving installers and engineers the flexibility to pair it with a separately sourced or existing float for custom liquid level control applications. Featuring Viton elastomer seals, this switch delivers outstanding chemical and temperature resistance, making it well-suited for demanding industrial, commercial HVAC, and hydronic system environments where standard seals may degrade.
Key Features
- 2.5″ float switch configuration for precise liquid level sensing
- Sold “less float” — compatible with separately sourced float balls for custom installations
- Viton (FKM) seals provide superior resistance to oils, fuels, hydraulic fluids, and a wide range of chemicals
- Viton elastomers maintain integrity across a broad temperature range, ideal for high-temperature fluid applications
- Square D 9037HG series construction built for long-term reliability in commercial and industrial service
- Suitable for use in boiler rooms, hydronic systems, cooling towers, and process fluid applications
Why Choose Viton Seals?
Viton (fluoroelastomer) seals outperform standard Buna-N or EPDM seals in environments involving petroleum-based fluids, aggressive chemicals, or elevated operating temperatures. Choosing the 9037HG32LZ20 with Viton ensures longer service life and reduced maintenance intervals in challenging fluid control applications.
Application Notes
- Designed for liquid level control in tanks, vessels, and hydronic systems
- “Less float” configuration allows use with existing float hardware or custom float selection
- Part of the Square D 9037HG series of industrial float switches
- Consult Schneider Electric documentation for full electrical ratings, enclosure type, and compatible float accessories
