SFA Sanipump VX 50.2 SA Submersible Pump - Fixed Automatic Version

The SFA Sanipump VX 50.2 SA submersible pump is an automatic and high-performance solution for the evacuation of wastewater and rainwater in all types of installations. Made of EN-GJL-250 cast iron, it is equipped with a vortex-type impeller and an integrated float for autonomous operation according to the water level, allowing the automation of pumping management without the need for external control.

With a maximum head height of 12 meters and a flow rate of up to 23 m³/h, this pump is capable of transporting water loaded with suspended solids up to 45 mm, ensuring reliable operation even in demanding conditions. The DN 50 outlet facilitates its connection to conventional evacuation systems.

The VX 50.2 SA model features single-phase power supply of 220-240 V and offers an absorbed power of 1250 W, with a useful power output of 750 W. The motor rotates at 2800 rpm and is prepared for continuous operation (service S1) as long as it remains completely submerged. The electrical class is I and the motor insulation corresponds to class F.

This version is designed for fixed installation and comes with a 10-meter power cable, type H07 RN8-F with a section of 3x1 mm², facilitating its placement in deep pits, septic tanks, reservoirs, or other hydraulic infrastructures. It is fully compatible with Sanifos 1600, 2100, and 3100 pumping stations, ensuring optimal integration in new or existing installations.
