SFA Sanipump VX 50.4 SA Submersible Pump - Fixed Automatic Version

The submersible pump SFA Sanipump VX 50.4 SA, reference AP0011, is an automatic single-phase pump for fixed installation for the evacuation of rainwater or wastewater. It is equipped with a high-performance vortex impeller and an integrated float switch that automatically activates the system when the predetermined water level is reached.

Thanks to its hydraulic design and its free passage of solids up to 41 mm, it is ideal for evacuating loaded water from sumps, wells, or tanks. It offers a maximum flow rate of 29 m³/h and a head height of up to 16 m, making it suitable for residential, commercial, or industrial applications.

The pump is entirely made of EN-GJL-250 cast iron (body, motor, impeller, and base), ensuring excellent durability in demanding environments. The motor shaft is made of stainless steel, and the sealing system includes a high-resistance mechanical seal in SIC/Al₂O₃ on the hydraulic side and a shaft seal on the motor side.

The automatic start is performed by an integrated float switch, which starts the pump when the water level reaches 400 mm and stops at 100 mm. It comes with a 10-meter power cable, allowing its installation in deep sumps without the need for additional accessories.
