Lowara e-SV
Lowara vertical multistage centrifugal pumps in stainless steel, in 11 sizes, with flows up to 160 m³/h and heads up to 330 m.
e-SV is the Lowara range of vertical multistage centrifugal pumps, non-self-priming, built in stainless steel, for clean or slightly contaminated liquids. The range has 11 sizes, with nominal flows of 1, 3, 5, 10, 15, 22, 33, 46, 66, 92 and 125 m³/h; Xylem documentation indicates flows of up to 160 m³/h, heads of up to 330 m and standard motors of 0.37–55 kW, single-phase or three-phase, at 50 and 60 Hz. Besides the standard version there is e-SV with integrated Hydrovar X drive and the e-SVE (Smart Pump) configuration, with variable speed.
The type code is read from the nameplate: in 10SV05F022T, “10” is the nominal flow in m³/h, “SV” the series, “05” the number of impellers, “F” the AISI 304 version with round PN 25 flanges, “022” the motor power multiplied by 10 (2.2 kW), and “T” three-phase supply. On sizes 33–125 there are also reduced-diameter impellers (for example “8/2A”) and the G version, in AISI 304 and cast iron. For a quotation please send us the full code or, for a new installation, the flow and head required, the liquid and its temperature; to order, the lead time is usually 1–4 weeks.

Frequently asked questions
How do you read the code of an e-SV pump from the nameplate?
The first number is the nominal flow in m³/h, followed by “SV”, the number of impellers, the letter for the material and connections (for example F or G), the motor power multiplied by 10 and the letter for the supply (T three-phase, M single-phase). For example, 22SV14F150T means size 22 m³/h, 14 impellers, F version and a 15 kW three-phase motor.
How does standard e-SV differ from e-SVE?
Standard e-SV runs at fixed speed; e-SVE is the Smart Pump configuration, with a variable frequency drive and a synchronous motor, and e-SV is also supplied with integrated Hydrovar X. The variable speed version is chosen when the flow required by the installation varies.
Can the mechanical seal be replaced without removing the motor?
Yes, on e-SV pumps with a motor above 4 kW, according to Xylem documentation, the mechanical seal can be replaced without removing the motor. For a replacement seal we need the full pump code.
Other Lowara series
We do not do the hydraulic sizing on the pump curve and we do not confirm mounting compatibility with pumps from other series; we confirm the code and version from the Lowara documentation.
