Product description

XVN-F 1 is the smallest model in the XVN-F range featuring hydraulics made entirely of AISI 316 stainless steel—a chemically resistant design for aggressive media. The DN 25 flange and flow rate of up to 2.4 m³/h (40 l/min), along with six configurations based on the number of stages (7 to 40), cover heads from 15 m to 237 m.

With motors rated at 0.37–2.2 kW, the XVN-F 1 is designed for applications involving low flow rates, but high pressure and aggressive media—reverse osmosis, saltwater treatment, dilute acids, and industrial processes using chemically demanding liquids. Power supply: 230/400 V three-phase.

The impellers, diffusers, shaft, outer casing, and suction foot are made of AISI 316. The upper body is made of high-strength cast iron and does not come into contact with the pumped medium. Operating pressure up to 25 bar, medium temperature -15 °C to +120 °C.

Applications

  • Reverse osmosis – high-pressure supply to membrane modules.
  • Saltwater and brackish water treatment – AISI 316 resistance to chlorides.
  • Chemical industry – pumping diluted acids and chemical solutions.
  • Food and pharmaceutical industries – CIP/SIP stations where AISI 316 is required.
  • Industrial washing and rinsing – demineralized water, aggressive cleaning solutions.
  • Electroplating lines – pumping process fluids.

Key benefits

  • All-wetted hydraulic components made of AISI 316 – impellers, diffusers, shaft, casing and suction foot. No contact between the fluid and cast iron.
  • Head up to 237 m – the highest in the entire XVN-F 1 range, for high-pressure applications.
  • 6 configurations – from 1-7 (0,37 kW) to 1-40 (2,2 kW).
  • Fluid temperature up to 120 °C – unlike V-NOX and VAT (45 °C).
  • Operating pressure of 25 bar – higher than that of standard smaller XV-F sizes.
  • Compatible with a frequency converter – Class F motor, IP-55.

Optional accessories

What is the difference between XVN-F and XV-F?

XVN-F has hydraulic components made entirely of AISI 316, which resists chlorides, diluted acids and saltwater. XV-F has hydraulic components made of AISI 304, which is sufficient for drinking water and common fluids. Choose XVN-F for aggressive liquids and XV-F for standard applications.

What liquids is the XVN-F 1 designed for?

For aggressive fluids: saltwater, brackish water, diluted acids, demineralized water, chemical solutions and liquids with a higher chloride content. The fluid must not contain solid or abrasive particles.

Is the XVN-F 1 suitable for drinking water?

Yes, AISI 316 meets the requirements for contact with drinking water without any issues. However, for standard drinking water, the XV-F 5 (AISI 304) is more economical.

What is the warranty?

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