Product description

XV-F 32 is the first model in the XV-F range with a DN 65 flange—a step up to a higher flow class compared with the DN 50 connection on the XV-F 15 and XV-F 20 models. A flow rate of up to 40 m³/h (667 l/min) and seven configurations by number of stages (3 to 14) cover heads from 29 m to 278 m.

With 5.5–30 kW motors and PN 16–25–40 flanges, the XV-F 32 is designed for medium-sized and large industrial applications, including booster stations in office complexes, boiler feed, fire-fighting systems and cooling circuits. All versions are three-phase 400/690 V.

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 dismantling the hydraulic section.

Applications

  • Pressure boosting stations in large residential and commercial buildings (100+ residential units).
  • Fire suppression systems (FSS) and sprinklers for larger and high-rise buildings.
  • Steam and hot-water boiler feed – fluid temperature up to 120 °C, operating pressure up to 40 bar.
  • Industrial cooling and process circuits with higher flow rates.
  • CIP/SIP stations in the food and pharmaceutical industries (AISI 316 version available on request).
  • Water supply and treatment plants – pressure boosting in distribution networks.

Key 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 fluids, with a long service life.
  • Flanges rated up to PN 40 – higher operating pressure than smaller models (PN 25).
  • 7 configurations – the widest choice of stages in the entire XV-F range, from 3 to 14 stages.
  • IE3 motor compatible with a variable frequency drive – energy savings in variable-speed operation.
  • DN 65 in-line flanges – move up to a higher flow-rate class while maintaining a compact footprint.

Optional accessories

What is the difference between the XV-F 20 and XV-F 32?

The XV-F 32 has larger ports (DN 65 vs DN 50), a higher maximum flow rate (40 m³/h vs 28 m³/h), more powerful motors (up to 30 kW) and flanges rated up to PN 40 (vs PN 25). Choose the XV-F 32 when you need a higher flow rate or an operating pressure above 25 bar.

Why does the XV-F 32 have seven versions while the other models have five?

The XV-F 32 covers a very wide head range (29–278 m), so it offers 7 stage configurations – from the light-duty 32-3 (3 stages, 5.5 kW) to the high-performance 32-14 (14 stages, 30 kW). This lets you match the duty point more precisely without unnecessary oversizing.

Is the XV-F 32 suitable for drinking water?

Yes. The hydraulic section made of AISI 304 stainless steel meets the requirements for contact with drinking water in accordance with ČSN EN 16421. For the food and pharmaceutical industries, we recommend requesting the AISI 316 version.

Do I need counter-flanges for the pump?

Yes, DN 65 counter-flanges are not included in the standard delivery. We recommend a PN 25 or PN 40 set (depending on the application), including a flat gasket.

Can the XV-F 32 be controlled by a variable frequency drive?

Yes. The IE3 motor, with IP-55 protection and epoxy-impregnated windings, is designed for operation with a variable frequency drive. Select the drive according to the output of the chosen version (5.5–30 kW).

What is the warranty?

We provide a 24-month warranty on XV-F pumps. 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.
