SFA Sanipump VX 50.4 S Submersible Pump

The submersible pump SFA Sanipump VX 50.4 S, reference AP0010, is an electric pump designed for fixed installation to evacuate wastewater or rainwater in technical, domestic, or commercial applications. Made of cast iron, this single-phase version is equipped with a vortex-type impeller, allowing for efficient and safe operation with water loaded with solids.

The pump can reach a flow rate of up to 29 m³/h and a maximum head of 16 m. The vortex-type impeller allows the passage of solid particles up to 41 mm, making it ideal for evacuating water with leaves, sand, paper, or organic waste. It is designed for continuous use (S1) and can be submerged up to 10 meters deep.

This version does not include a level switch, allowing integration with external control panels. It is perfect for pumping stations like Sanifos 1600, 2100, or 3100, or for custom installations requiring an automated activation system.

All its components are designed to withstand demanding conditions: body, motor, and impeller in EN-GJL-250 cast iron, stainless steel shaft, and sealing system with a shaft seal on the motor side and SIC/Al₂O₃ mechanical seal on the hydraulic side. The power cable is 10 meters long.
