SFA Sanipump ZF 100 EX T Three-Phase Submersible Pump

The SFA Sanipump ZF 100 EX T submersible pump is a professional solution for the evacuation of wastewater and rainwater with large solids, specifically designed for use in pumping stations, sumps, or wells in industrial, municipal, or commercial installations. This three-phase version is part of SFA's ATEX range, ensuring safe operation in potentially explosive or demanding environments.

Equipped with a GG-25 cast iron single-channel impeller and a solid passage of up to 100 mm, the ZF 100 EX T can evacuate a flow rate of up to 120 m³/h and reach a maximum head height of 10 meters. This pump allows efficient handling of liquids with a high solid load without the risk of blockages, making it ideal for sewage or rainwater networks in urban or industrial installations.

The 3300 W three-phase motor operates at 1450 rpm and is protected by a double sealing system composed of a carbon/ceramic mechanical seal, preventing water infiltration into the motor. Additionally, it features IP68 protection and is designed for continuous immersion operation (S1 service) and intensive intermittent operation (S3 40%).

The pump can be installed directly at the bottom of the well or sump, thanks to its robust design and resistant materials. It includes a 10-meter power cable type S1BN8-F, with a section of 1.5 mm². The entire assembly has been developed to offer maximum operational reliability, long service life, and low maintenance in demanding conditions.
