The Speroni Float Switch (5M) is a high-reliability, professional-grade level control sensor designed to automate the operation of electric pumps. Engineered for durability in both clean and greywater applications, this Italian-designed switch is a critical component for managing water levels in tanks, sumps, and reservoirs throughout the Heidelberg - GP region.
Technical Specifications
- Cable Length: 5 Meters (High-flex, waterproof Neoprene/PVC jacket).
- Electrical Rating: 10(8)A / 250V AC (Suitable for most standard 0.37kW to 1.1kW pumps).
- Switching Function: Dual-action (Can be wired for "Emptying" or "Filling" operations).
- Maximum Depth: 10 Meters.
- Operating Temperature: 0C to 50C.
- Protection Class: IP68 (Fully submersible and dust-tight).
Key Performance Features
- Dual-Function Versatility: Features a changeover contact (SPDT), allowing it to either turn a pump ON when the tank is full (drainage) or turn a pump OFF when the tank is empty (protection against dry-running).
- Counterweight Precision: Includes a heavy-duty adjustable counterweight that allows you to set the exact "pivot point," defining the distance between the pump’s start and stop levels.
- Heavy-Duty Cable: The 5-meter lead is designed to resist kinking and chemical degradation, ensuring it remains flexible during the colder Winter 2026 months in Gauteng.
- Universal Compatibility: Seamlessly integrates with Pascali, Speroni, and Pentax centrifugal or submersible pumps to create a fully automated water management system.
- Non-Toxic Construction: Manufactured with high-impact, non-toxic polypropylene, making it safe for use in JoJo Tanks intended for garden irrigation or livestock watering.
Installation & Professional Tips
- Wiring Configuration: * Emptying (Drainage): Connect the Black and Brown wires. The pump starts when the float is UP.
- Filling (Tank): Connect the Black and Blue wires. The pump starts when the float is DOWN.
- The Pivot Point: Slide the counterweight onto the cable and secure it with the locking clip. The distance between the counterweight and the float determines the "differential"—a shorter distance means the pump will cycle on and off more frequently.
- Dry-Run Protection: For borehole or booster pumps, install the float switch in the supply tank. This ensures that if the tank runs dry during a heavy-use Easter 2026 period, the switch will cut power to the pump before the motor burns out.
- Avoid Obstructions: Ensure the float has a clear "swing" path. If the float gets snagged on a ladder, a pipe, or the side of a narrow sump, the pump may stay on indefinitely or fail to start.
- Waterproofing Joints: If you need to extend the 5m cable, always use a SABS-approved resin-filled Scotchcast joint or an IP68-rated waterproof junction box. Standard electrical tape will fail underwater, leading to short circuits.
Common Use Cases
- Rainwater Harvesting: Automating the transfer of water from a collection sump to a JoJo storage tank.
- Sewage & Waste: Controlling submersible macerator pumps in underground waste pits.
- Booster Systems: Protecting Pascali pumps from running dry when municipal water supply is interrupted.
- Agricultural Troughs: Ensuring livestock water levels remain consistent without manual monitoring.
Pro Tip: If your pump is larger than 1.1kW (1.5HP), do not wire the float switch directly to the motor. Instead, use the float switch to trigger a Magnetic Contactor in your control box. This prevents the high "start-up" current of a large motor from melting the delicate microswitch inside the float, significantly extending its lifespan. Always check for debris or "fat" buildup on the float during your Winter 2026 maintenance check to ensure it moves freely.
