Product description Key benefits Controls pumps and regulates liquid level automatically, preventing overflow and dry-run conditions. Simple, reliable operation based on proven gravity and buoyancy principles — no complex electronics required. Durable, corrosion-resistant construction from high-quality polypropylene ensures long service life and low maintenance. Easy to install and adjust; compatible with submersible pumps for straightforward integration into existing systems. Safe, non-toxic, and environmentally friendly materials and design. What it does Acts as a float switch to start and stop the pump according to liquid level. Provides automatic level adjustment with a compact, reasonable mechanical structure that delivers dependable performance. Main attributes Function: Pump control and liquid level regulation. Compatibility: Designed to be installed on submersible pumps; suitable for integration with common pump setups. Material: High-quality polypropylene — corrosion-resistant, durable, and lightweight. Performance: Gravity-and-buoyancy mechanism delivers stable, repeatable switching; automatic adjustment minimizes user intervention. Safety and environment: Non-toxic materials and a simple design reduce contamination risk and support environmentally responsible use. Practical use scenarios Basement sump pump systems: Automatically start the pump when water rises and stop it when the level drops to prevent flooding and pump damage. Water storage and transfer: Maintain set levels in tanks or cisterns for irrigation, domestic supply, or process systems. Small wastewater or drainage applications: Control submersible pumps in sites such as construction drains, small treatment setups, or floor drains where reliable level control is required. Why choose this float switch Mechanical simplicity and polypropylene construction mean fewer failure points and long-term reliability. Designed for easy mounting on submersible pumps and straightforward installation, reducing setup time and service costs. Practical for a wide range of everyday pump control tasks while remaining safe and environmentally responsible.
