SFA Sanipump ZFS 71.1 EX T Three-Phase Submersible Pump

The SFA Sanipump ZFS 71.1 EX T submersible pump is designed to efficiently evacuate wastewater in collective, sanitary, or technical installations requiring safety and continuous performance. Equipped with a PRO X K3 bladed impeller and ATEX certification, this pump is suitable for potentially explosive environments and demanding settings such as pumping stations, public premises, or collectives.

This three-phase version features a 1700 W (P2) motor and a GG-20 cast iron impeller with a DN 50 free passage, allowing it to shred solids and evacuate high-load water without the risk of clogs. It offers a head height of up to 22 meters and a maximum flow rate of 17 m³/h, making it suitable for medium-long evacuations in technical installations.

The pump is designed for continuous (S1) or intermittent (S3 40%) submerged operation and features a double mechanical seal in carbon/ceramic that protects the motor against leaks. The motor shaft is made of stainless steel, and the entire structure is constructed from GG-20 cast iron, ensuring mechanical strength and durability against corrosion and abrasion.

It includes a 10-meter power cable (type S1BN8-F, 1.5 mm² section), ideal for installation in wells or pits up to 5 meters deep. This pump is fully compatible with Sanifos 1600, 2100, and 3100 prefabricated pumping stations, facilitating its integration into complete evacuation solutions.
