Atmos BST Flange

The universal single-stage centrifugal pump for many applications in heating, cooling and industrial circulation systems.

The wide range of hydraulic components and motors available for the single-stage centrifugal pump Wilo-Atmos BST enable it to be deployed for a variety of applications in air conditioning and cooling technology, water supply, pressure boosting and water treatment. It can be used to pump water as well as non-aggressive and slightly aggressive liquids, for example in a car wash, for industrial cooling systems or for irrigation in agriculture. Its hydraulic components made of stainless steel provide high resistance to corrosion and long service life. The block construction combined with the pump feet enable quick installation as well as low-vibration and quiet-running operation. The modern pump hydraulics together with the IE3 motors equipped as standard save energy.


Your advantages

  • Ultra-modern pump hydraulics and the IE3 motor save energy
  • Various impeller materials, multiple motor options and a wide range of mechanical seals enable universal deployment in many different applications
  • Block construction and pump feet enable easy installation
  • Hydraulic components made of stainless steel provide high resistance to corrosion and long service life
