SFA Sanipump ZFS 71.3 EX T Three-Phase Submersible Pump

The SFA Sanipump ZFS 71.3 EX T submersible pump is designed for professional applications that require the evacuation of wastewater with a high solid load to significant heights. Thanks to its PRO X K3 blade impeller and ATEX certification, this pump offers safety, performance, and durability even in industrial or public environments with intensive use.

This three-phase version is equipped with a 3200 W (P2) motor, capable of reaching a maximum head height of 35 meters and a flow rate of up to 17 m³/h. It is especially suitable for long vertical evacuations, deep pumping stations, or technical installations that require maximum reliability in wastewater management.

The pump is entirely made of GG-20 cast iron and features a stainless steel shaft. The double mechanical seal in carbon/ceramic ensures optimal tightness even under continuous immersion conditions (S1 mode), as well as in intermittent operation (S3 40%). Its 2800 rpm design allows for efficient solid shredding without compromising the durability of the components.

The system is completed with a 10-meter power cable (S1BN8-F, 1.5 mm² section), suitable for immersion up to 5 meters deep. It is compatible with Sanifos 1600, 2100, and 3100 prefabricated pumping stations, allowing for direct integration into SFA's preconfigured evacuation solutions.
