Product description

VAT 205 is the largest model in the VAT range, with 2 1/2" suction and discharge connections and a flow rate of up to 45 m³/h (750 l/min). Five configurations with 2 to 6 stages cover heads from 23 m to 158 m.

With motors rated at 7,5–18,5 kW, the VAT 205 exceeds the typical range of compact pumps and enters the industrial power class—making it suitable for large pressure-boosting stations, main pumps in fire sprinkler systems and industrial distribution networks. All versions are three-phase 400/690 V only.

The GG-25 cast iron suction and discharge casings, bronze impellers with inserts, and Noryl diffusers (GFN-2). The shaft and casing are made of AISI 304 stainless steel. Ceramic/graphite mechanical seal. Mating flanges included.

Applications

  • Large booster stations – industrial facilities, shopping centers, hospitals.
  • Main pump in fire protection systems – fire protection systems requiring higher flow rates and head.
  • Industrial water distribution – water supply in manufacturing plants.
  • Irrigation systems – medium-sized and large agricultural operations.
  • Supplementary and booster pump – increasing pressure in distribution networks.

Key benefits

  • Flow rate up to 45 m³/h – the highest in the VAT range, putting it in the industrial class.
  • Head up to 158 m – suitable for most pressure boosting and firefighting applications.
  • Bronze impellers – greater durability and service life than Noryl impellers used in smaller models.
  • Counter-flanges included – ready for installation.
  • 5 configurations – from 205-2 (7,5 kW) to 205-6 (18,5 kW).
  • 400/690 V – direct connection to industrial electrical panels.

Optional accessories

  • O-rings: POWERseal EPDM
  • Variable frequency drive 7,5–18,5 kW, depending on the version

What is the difference between VAT 205 and XV-F 32?

VAT 205 has threaded connections (2 1/2") and counter-flanges included, making installation easier. XV-F 32 has DIN DN 65 flanges, a cartridge mechanical seal, and handles media temperatures up to 120 °C (compared with 45 °C for VAT). Choose XV-F for industrial applications involving higher temperatures or requiring flanged connections. For simpler installations with threaded connections, choose VAT 205.

Why does VAT 205 have bronze impellers?

Higher flow rates and power require greater mechanical strength from the impellers. Bronze offers better fatigue strength and corrosion resistance than Noryl, which is used in the smaller VAT 127 L and 163 L models.

What is the warranty?

VAT pumps come with a 24-month warranty.
