SFA Sanipump ZF 105 EX T Three-Phase Submersible Pump

The SFA Sanipump ZF 105 EX T submersible pump is designed for the evacuation of wastewater and rainwater in environments that demand high hydraulic capacity and robust construction. With a single-channel impeller, 100 mm solid passage, and ATEX certification, this pump is perfect for pumping stations, pits, or industrial sumps.

Thanks to its 5500 W (P2) three-phase motor, the ZF 105 EX T can reach a maximum head of 18 meters and a flow rate of up to 160 m³/h. This model is especially suitable for installations that require evacuating large volumes of water with large solids, such as sewage networks, industrial areas, treatment stations, or rainwater evacuations from large surfaces.

Its design includes a double mechanical seal in carbon/ceramic, which effectively protects the motor against water ingress, even in continuous operation conditions (S1) or intensive intermittent cycles (S3 40%). The pump operates at 1450 rpm, reducing component wear and ensuring a longer system lifespan.

Entirely made of GG-25 cast iron, both in the pump body and the impeller, motor, and base, this pump stands out for its mechanical resistance, stability, and reliability even in the most demanding conditions. The stainless steel shaft provides greater durability against corrosion. It includes a 10-meter power cable type S1BN8-F, prepared for submerged installations up to 5 meters.
