SFA Sanipump ZFS 71.2 EX T Three-Phase Submersible Pump

The SFA Sanipump ZFS 71.2 EX T submersible pump is a high-performance professional solution designed to evacuate wastewater with solids from public, collective, or technical facilities. Thanks to its PRO X K3 blade impeller, ATEX certification, and double sealing system, this pump is ideal for situations where safety, power, and reliability in evacuation are required.

This three-phase version allows reaching a head height of up to 25 meters with a flow rate of 17 m³/h, making it an ideal option for medium-distance vertical evacuations, such as deep wells, technical pits, or installations with long hydraulic runs. The integrated grinder impeller allows for the evacuation of black water with solids without the risk of blockage or clogging.

The 1700 W (P2) three-phase motor is prepared to operate continuously (S1 mode) or in intensive intermittent cycles (S3 40%), with a speed of 2800 rpm. It is fully protected by a double mechanical seal in carbon/ceramic that ensures tightness against liquid entry into the motor compartment. The shaft is made of stainless steel, and the assembly is manufactured in GG-20 cast iron for superior resistance in humid and aggressive environments.

The pump is supplied with a 10-meter power cable (S1BN8-F, 1.5 mm² section), suitable for immersion up to 5 meters deep. It is compatible with the Sanifos 1600, 2100, and 3100 prefabricated stations, facilitating its integration into complete pumping systems.
