SFA Sanipump VX 50.3 SA Submersible Pump

The submersible pump SFA Sanipump VX 50.3 SA, reference AP0008, is a compact, automatic, and high-performance solution for the evacuation of wastewater or rainwater from pits, tanks, or reservoirs. Thanks to its vortex impeller and automatic float detection system, it offers efficient operation without constant supervision, ideal for installations in homes, commercial premises, or small technical infrastructures.

The pump is equipped with a cast iron vortex impeller EN-GJL-250 that allows the evacuation of water loaded with solids up to 41 mm in diameter. The 1100 W single-phase motor provides a head height of up to 16 meters and a maximum flow rate of 29 m³/h, ensuring quick evacuations even in sections with slopes or long distances.

This version includes an integrated level float, allowing automatic activation and shutdown based on the water level. The pump activates when the level reaches 400 mm and stops at 100 mm. It is easily installed in construction pits or collection wells and is compatible with stations like Sanifos 1600, 2100, and 3100.

Entirely made of cast iron and stainless steel, with body, motor, and impeller in EN-GJL-250 and shaft in stainless steel, it is designed to operate in continuous mode (S1) and withstand immersions up to 10 meters. The 10-meter power cable is included and pre-installed.
