Three-phase Submersible Pump SFA Sanipump ZFS 71.4 EX T

The SFA Sanipump ZFS 71.4 EX T submersible pump is the highest hydraulic performance version within the ZFS 71 EX series, designed to discharge wastewater in installations requiring maximum discharge height. Thanks to its PRO X K3 blade impeller, robust construction, and ATEX certification, this pump offers safety and efficiency for demanding discharges in communities, technical buildings, industries, or sanitation networks.

With a three-phase motor of 3200 W (P2), this pump reaches a maximum head height of 39 meters and maintains a flow rate of up to 17 m³/h. Its grinder impeller is capable of processing water with a high solid load, reducing the risk of blockages in vertical or long-distance discharge systems.

Entirely made of GG-20 cast iron and with a stainless steel shaft, the ZFS 71.4 EX T is prepared for continuous use (S1 mode) or intensive intermittent use (S3 40%), with guaranteed tightness through a double mechanical seal in carbon/ceramic. Its rotation speed of 2800 rpm provides effective waste shredding and ensures a constant flow.

The pump is supplied with a 10-meter power cable (S1BN8-F, 1.5 mm² section) and can be installed in immersions of up to 5 meters. It is compatible with the Sanifos 1600, 2100, and 3100 prefabricated pumping stations, facilitating its integration into complete preconfigured evacuation solutions.
