Taking reliability and performance to new depths

The e-SVI is an efficient, reliable, high-performance pump, comprised of an energy saving, vertical multistage pump coupled to a IEC high efficient motor. Plus, an immersible hydraulic end provides an ideal solution for top mount applications.
Industry-leading range, with flows up to 120 m³/h and sizes from 1 to 92, meets the demands of a wide variety of applications in the industrial, OEM and commercial building services markets

An immersible top tank solution

The e-SVI is specially designed to be mounted on the top of a tank, with the pump unit immersed in the liquid to be pumped. The length of the immersed pump unit can vary, depending on the solution your application requires.


Precision laser welded impellers reduce hydraulic losses and optimize pump efficiency.
IEC high efficient motors, combined with the optimized hydraulic design of the e-SVI pump, reduce energy consumption and operating costs.
Xylem Hydrovar® drives and IE5 efficient Smart Motors are available, to further improve the performance of the system.

Easy repair

The mechanical seal (non-cartridge) can be replaced without removing the motor in sizes 33-92, to simplify repair and minimize downtime.
The e-SVI is an interchangeable drop-in replacement for pumps with 1”1/4 or 2” Rp threaded fittings, or with DN80 compatible flange discharge connections.
The reduced axial thrust design makes it possible to use motors with standard bearings. This allows easy selection of standard motors reducing cost and increasing availability

Mechanical seal options

An assortment of mechanical seals and materials are available, which are designed to handle a wide range of temperatures, high pressures and aggressive liquids with ease.
Easy-to-replace, pre-assembled cartridge seals are available, to help ensure correct assembly.
