SFA Sanipump ZFS 71.1 EX S Submersible Pump - Grinder Version

The SFA Sanipump ZFS 71.1 EX S submersible pump is designed to evacuate wastewater in demanding environments such as collective sanitary facilities, pumping stations, or public infrastructures. This single-phase version combines power, safety, and reliability, thanks to its PRO X K3 blade impeller and ATEX certification, making it suitable for operation in potentially explosive atmospheres.

Its grinder impeller allows handling water with solids without the risk of clogging, offering a flow rate of up to 17 m³/h and a maximum head of 22 meters. Thanks to its compact design and double carbon/ceramic sealing system, the pump is protected against leaks and prepared for intensive use in continuous submerged mode (S1) or intermittent (S3 40%).

Made of GG-20 cast iron and with a stainless steel shaft, this pump offers optimal resistance to abrasion and corrosion. It can be installed in pits, wells, or tanks, and is fully compatible with Sanifos 1600, 2100, and 3100 prefabricated pumping stations.

The pump includes a 10-meter power cable (type S1BN8-F, 1.5 mm² section), suitable for immersions up to 5 meters deep. Its 1600 W (P2) motor operates at 2800 rpm with IP68 protection and class F insulation, ensuring reliable performance even in demanding conditions.
