SFA Sanipump ZPG 71.1 S Submersible Pump

The SFA Sanipump ZPG 71.1 S submersible pump is designed to evacuate rainwater or greywater from tanks, wells, or prefabricated pumping stations like Sanifos. Thanks to its compact design, dual-channel impeller, and 40 mm free solid passage, this pump is suitable for both residential and collective installations that require performance, reliability, and ease of maintenance.

The ZPG 71.1 S version is single-phase, with a useful power of 1600 W (P2), and offers a flow rate of up to 43 m³/h with a maximum head of 19 meters. Its high-speed motor (2800 rpm) allows for optimal performance, and its continuous submerged design (S1) ensures safe and durable operation under full immersion.

The pump body, motor, base, and impeller are made of GG-20 cast iron, with a stainless steel shaft and double mechanical seal in carbon/ceramic that effectively protects the motor from water infiltration. Its structural robustness, combined with ease of installation, makes it a very versatile pump for both new constructions and renovations.

It includes a 10-meter power cable (S1BN8-F, 1.5 mm²), prepared for submerged installations up to 5 meters. This pump can be installed directly at the bottom of the tank or with a coupling foot, depending on the installation configuration. It is fully compatible with the Sanifos 1600, 2100, and 3100 models, allowing for direct integration into complete SFA pumping stations.
