Lowara e-SV range: pumping performance at new levels

The Lowara e-SV range is a series of fabricated vertical multistage pumps designed to enhance efficiency, durability, and versatility. These pumps are constructed from high-quality stainless steel, ensuring robust performance even in demanding environments. The e-SV pumps are engineered to handle a variety of liquids, from clean water to slightly contaminated fluids, making them suitable for a wide range of applications.

The e-SV range includes 11 models with 1-3-5-10-15-22-33-46-66-92-125 m³/h nominal capacities, allowing different flow rates and pressures to meet diverse needs. Here are some key specifications:

• Flow Rate: Up to 160 m³/h
• Head: Up to 330 meters
• Power Supply: Available in three-phase and single-phase options, 50 and 60 Hz
• Power: Standard motors from 0.37 kW to 55 kW
• Operating Pressure: PN25-40 for sizes 1-22SV; PN16, PN25, PN40 for sizes 33-125
• Temperature Range: -30°C to +120°C (standard version), with high-temperature options available up to +180°C

All pumps are equipped with IE3 standard motors if three-phase ≥0.75kW and with IE2 motors if single-phase.

What’s more, the e-SV is available with integrated Hydrovar X, as well as in the e-SVE Smart Pump configuration, both featuring advanced frequency converters combined with the latest synchronous motor technologies. This integration reduces the number of components and significantly enhances overall system reliability. Supplied as pre-programmed pre-assembled packages, both the e-SV with Hydrovar X and the e-SVE Smart Pump offer market-leading efficiency, with energy savings of up to 70% compared to fixed-speed systems, while also minimizing installation time straight out of the box.

“The Lowara e-SV range is not just a product”, says Nicola Elevati, Senior Product Manager in Xylem. “It's a solution that elevates pump performance to new heights, ensuring efficiency, reliability, and satisfaction across various applications”.
