Lowara – e-SVI

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.

Performance

• Industry-leading performance and range, with flows up to 120 m3/h, meet the demands of a wide variety of applications.
• The e-SVI range 1-22 features an inducer as part of our standard offering. The inducer helps protect against dry run and allows for reliable low-level pumping.
• An assortment of materials and configurations let you create the right pump for the job at hand.
• An all-316SS version is available, to handle aggressive liquids and more demanding applications.
• A compact close-coupled option is available in three sizes, for applications with limited overhead clearance.
• A drain-back-to-tank design feature that comes standard on close coupled configurations allows pumped liquid to return to the tank, which minimizes spillover.
• The e-SVI can be built with a variable number of impellers, to cover a wide range of duty points.
• The e-SVI can be configured to allow an additional number of blank stages, so that the height of the immersed part can accommodate different suction depths.

Reliability

• Our pump experts ensure that your pump is optimized for your application and designed to deliver the longlasting, reliable service that you expect.

Efficiency

• 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.
