  • Temperature range of 10-180°C accomodates almost any application.Internal bellows design allows for higher pressure ratings by eliminating the failure points of traditional flat diaphragms and extending the pump's service life.

  • Innovative clamp design allows for field repair, greatly reducing maintenance costs.

  • Accurate, predictable flow rate is provided by "smart sensors" that control air via proximity sensors: no separate flow meter is necessary.

  • Reliable leak detection feature provides for "lights out" operation without fear of contaminating wet bench chemistry.
