SFA Sanipump VX 50.3 S Submersible Pump - Fixed Manual Version

The submersible pump SFA Sanipump VX 50.3 S, reference AP0007, is a manual fixed version specially designed for the evacuation of wastewater and rainwater from sumps, wells, or tanks. Made of high-strength cast iron, this pump is intended for demanding environments in residential, collective, or industrial installations.

Equipped with a vortex impeller, it offers a maximum flow rate of 29 m³/h and can pump water to a height of up to 16 meters. The vortex design allows for a solid passage of up to 41 mm, minimizing the risk of blockages and ensuring reliable operation in loaded waters.

This version is designed to be managed via an external control system (control panel or automation), as it does not include a float switch. This allows it to be integrated into customized installations or pumping stations with existing control logic.

Constructed from EN-GJL-250 cast iron, both the pump body and the motor and impeller, this pump guarantees great durability. The shaft is made of stainless steel and the sealing system includes a mechanical seal in SIC/Al₂O₃ on the fluid side and a sealing gasket on the motor side.

It is designed to operate in continuous submerged mode (S1) and allows up to 15 starts per hour. It is supplied with a 10-meter power cable (H07 RN8-F, 3x1 mm²) and can be submerged up to 10 meters deep.
