SFA Sanipump VX 50.2 S Submersible Pump - Fixed Manual Version

The SFA Sanipump VX 50.2 S submersible pump is designed for the efficient pumping of wastewater and rainwater in installations that require higher hydraulic performance. This single-phase version without automatic activation is perfect for use in tanks, pits, or sumps where start-up is controlled by external systems. Made entirely of cast iron, it guarantees excellent mechanical resistance, even in intensive applications.

With a maximum head of 12 meters and a flow rate of up to 23 m³/h, this pump allows the evacuation of liquids with suspended solids up to 45 mm, thanks to its vortex impeller, which minimizes the risk of blockages. The DN 50 outlet allows for easy integration into existing evacuation systems.

The VX 50.2 S model operates with single-phase power supply of 220-240 V, with an absorbed power of 1250 W and a useful returned power of 750 W. The motor runs at 2800 rpm, in electrical class I and with insulation class F. Designed for continuous service (S1), it offers reliable operation in prolonged immersion, being suitable for demanding environments that require resistance and high flow.

The pump is delivered in a fixed version and is equipped with a 10-meter long power cable, facilitating installation in deep pits or hard-to-reach areas. It is fully compatible with Sanifos 1600, 2100, and 3100 pumping stations, facilitating its integration into prefabricated or customized systems.
