Double Float Master Pump Switches

A piggyback float switch is a plug-in style switch that attaches directly to a pump's power cord, allowing it to control pump activation without separate wiring. It works alongside float balls to detect liquid levels and automatically start or stop the pump, commonly used in sump pump and effluent applications.

Float balls used in double float master pump switches are typically constructed from 304 or 316 stainless steel, chosen for their corrosion resistance and durability. 316 stainless steel is often specified for applications involving corrosive liquids or chemical exposure, while 304 stainless steel is common for general industrial and food-grade uses.

Yes, float balls can be custom-manufactured with integrated magnets for precise level detection, along with custom threads, fittings, or through tubes to match specific mounting and rod requirements. This allows the floats to integrate directly into existing pump switch assemblies and level control systems without modification.

Round float balls are available from 1-1/2 inch up to 14 inches in diameter, while oblong floats range from 2 x 6 inches up to 9 x 14 inches. Custom sizes and thread specifications can also be manufactured to match unique tank geometries and pump switch designs.

Yes, all float balls can be pressure-tested using dedicated equipment to meet customer-specified pressure ratings before shipment. This ensures the floats maintain buoyancy and structural integrity under high-pressure conditions found in vacuum tanks, steam traps, and sealed process vessels.

These float ball components are widely used in food processing, chemical manufacturing, wastewater treatment, and general industrial process control. They support applications such as sump pump activation, vacuum tank shutoff, steam trap liquid control, and tank level monitoring across corrosive and sanitary environments alike.
