SFA Sanipump VX 50.1 SA Submersible Pump - Fixed Automatic Version

The SFA Sanipump VX 50.1 SA submersible pump is designed for the automatic evacuation of wastewater and rainwater in all types of installations that require autonomous and continuous operation. Made from high-strength cast iron (EN-GJL-250), it features a vortex impeller and an automatic activation system via a float, allowing it to start and stop based on the water level.

With a maximum head height of 9 meters and a flow rate of up to 20 m³/h, this pump is ideal for evacuating liquids with suspended solids up to 45 mm. Its DN 50 outlet facilitates connection to conventional drainage networks, and its design allows for direct installation in sumps, wells, or tanks.

The VX 50.1 SA model operates on single-phase power supply of 220-240 V and has an absorbed power of 1000 W, delivering a useful output power of 550 W. The motor runs at 2800 rpm, in electrical class I, and with class F insulation, ensuring reliable performance under intensive use. It is prepared for continuous service (S1) when fully submerged.

Thanks to its automatic activation via float, this version is especially suitable for applications where autonomous water level control is required, without the need for constant supervision. Additionally, it is compatible with Sanifos 1600, 2100, and 3100 prefabricated pumping stations, facilitating its integration into existing or new systems.
