SFA Sanipump VX 50.2 T Three-Phase Submersible Pump - Fixed Manual Version

The SFA Sanipump VX 50.2 T submersible pump is a robust and high-performance solution designed to evacuate wastewater and rainwater in installations that require three-phase power. This fixed version without a float is designed to be managed via an external control system, allowing easy integration into programmable or automated electrical panels.

Thanks to its vortex impeller, this pump can handle liquids with suspended solids up to 45 mm, without the risk of clogging. It offers a maximum flow rate of 23 m³/h and a head height of up to 12 meters, making it an effective option for pumping systems in deep pits, sumps, or treatment stations.

The VX 50.2 T model operates with three-phase power at 400 V, with an absorbed power of 1100 W and a useful power output of 750 W. Its motor runs at 2800 rpm, in electrical class I and with insulation type F. It is designed for continuous service (S1), allowing it to remain in prolonged operation when fully submerged.

The pump body, motor, and impeller are made of EN-GJL-250 cast iron, with a stainless steel shaft and motor sealing system in SIC/AI203, ensuring durability, abrasion resistance, and reliability in demanding applications. It includes a 10-meter power cable (H07 RN8-F, section 4x1 mm²), suitable for deep installations.
