Product description

XVN-F 3 is the second model in the XVN-F range, with the same DN 25 connections as the XVN-F 1, but a higher flow rate of up to 4.4 m³/h (73 l/min). Six configurations with 6 to 31 stages cover heads from 19.5 m to 224 m.

With 0.55–3 kW motors, the XVN-F 3 delivers a higher flow rate while retaining AISI 316 chemical resistance — making it suitable for reverse osmosis, saltwater treatment and high-demand chemical processes. 230/400 V three-phase power supply.

All hydraulic components (impellers, diffusers, shaft, casing and suction foot) are made of AISI 316 stainless steel. Operating pressure up to 25 bar, fluid temperature -15 °C to +120 °C.

The standard maximum operating head and maximum operating flow rate are highlighted with a solid line.

Applications

  • Reverse osmosis – high-pressure supply to higher-flow membrane modules.
  • Saline and brackish water treatment – AISI 316 resistance to chlorides.
  • Chemical industry – pumping dilute acids and chemical solutions.
  • Food and pharmaceutical industries – CIP/SIP stations.
  • Industrial washing and rinsing – demineralized water, aggressive cleaning solutions.

Key benefits

  • Complete AISI 316 hydraulics – no contact between the fluid and cast iron.
  • Flow rate up to 4,4 m³/h – almost twice that of the XVN-F 1 while retaining DN 25.
  • Delivery head up to 224 m – for high-pressure applications.
  • Fluid temperature up to 120 °C – also suitable for hot, aggressive liquids.
  • Operating pressure of 25 bar.

Optional accessories

What is the difference between the XVN-F 1 and XVN-F 3?

Both have a DN 25 connection, but the XVN-F 3 offers a higher flow rate (4,4 m³/h vs 2,4 m³/h). The XVN-F 1 has a slightly higher maximum delivery head (237 m vs 224 m). Choose the XVN-F 3 when you need a higher flow rate; choose the XVN-F 1 when a lower flow rate and lower output are sufficient.

What is the warranty?

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