Product description

XV-F 10 is the second-smallest model in the SACI pumps XV-F series—a vertical multistage centrifugal pump with a DN 40 in-line flange and a flow rate of up to 12 m³/h (200 l/min). It is available in 6 configurations based on the number of stages (6 to 22), with heads ranging from 37 m to 225 m.

Compared with the smaller XV-F 5, it offers a higher flow rate and a wider DN 40 connection, making it better suited to the needs of medium-sized apartment buildings, commercial premises and light industrial applications. The 10-6 and 10-9 versions are available in a single-phase 230 V (M/T) configuration with integrated thermal protection and a capacitor.

The hydraulic section is made entirely of AISI 304 stainless steel, while the casing is made of GG-20 cast iron with anti-corrosion treatment. The cartridge mechanical seal (SiC/EPDM) can be replaced without disassembling the hydraulic section.

Applications

  • Pressure booster systems in apartment buildings (20–80 residential units), office buildings and hotels.
  • Fixed fire-fighting systems (FFFS) and sprinklers for small and medium-sized buildings.
  • Boiler feed – hot-water and steam boilers, with medium temperatures up to 120 °C.
  • Industrial cooling circuits with closed-loop circulation.
  • Irrigation systems – 10-6 and 10-9 versions are also available in single-phase 230 V models.
  • Pressure boosting in commercial and industrial piping systems.

Main benefits

  • Cartridge mechanical seal – replacement in 15 minutes, without dismantling the hydraulics.
  • Complete hydraulic section made of AISI 304 stainless steel – suitable for drinking water and mildly aggressive media, with a long service life.
  • 230 V and 400 V versions – 10-6 and 10-9 versions are also available as single-phase models with thermal protection.
  • IE3 motor compatible with a frequency inverter – energy savings in variable-speed operation.
  • In-line DN 40 flanges – easy installation in piping without a special frame.
  • Wide range of head – from 37 m (6 stages) to 225 m (22 stages) in a single size.

Optional accessories

  • O-rings: POWERseal EPDM, FEP-coated
  • DN 40 PN 25 counterflanges – not included in the delivery; we recommend ordering them with flat gaskets.
  • Replacement mechanical seal: SiC/EPDM cartridge
  • Frequency inverter 2.2–7.5 kW, depending on the version

Is the XV-F 10 suitable for drinking water?

Yes. The hydraulic section is made of AISI 304 stainless steel and meets the requirements for contact with drinking water under ČSN EN 16421.

What is the difference between the XV-F 5 and XV-F 10?

The XV-F 10 has a larger connection (DN 40 vs. DN 32 on the XV-F 5) and a higher maximum flow rate (12 m³/h vs. 8 m³/h). It is suitable where a higher flow rate is required – in larger apartment buildings, commercial properties and medium-sized pressure booster systems.

Which XV-F 10 versions are available in a single-phase 230 V model?

Only the XV-F 10-6 (2.2 kW) and XV-F 10-9 (3 kW). Both have integrated thermal protection and a start capacitor. Versions 10-10 and above are available only as three-phase 400 V models.

Do I need counterflanges for the pump?

Yes, DN 40 counterflanges are not included in the standard delivery. We recommend the PN 25 set – we can add it to your quotation on request.

Can the XV-F 10 be controlled using a frequency inverter?

Yes. The IE3 motor, with IP-55 protection and epoxy-impregnated windings, is designed for operation with a frequency inverter. Choose an inverter to match the power of the selected version (2.2–7.5 kW).

What is the warranty?

XV-F pumps come with a 24-month warranty. Replacement cartridge seals and O-rings are in stock in the Czech Republic – if needed, you can replace them yourself in just a few minutes.
