Details
  • The transportation of sample gas in sample conditioning systems requires reliable sample pumps. The corrosive nature of the gas and the potential of condensate formation are the real challenges for any pump design.
  • These sample pumps are equiped with bellows made from solid PTFE. This design has demonstrated the highest reliability and long lifetime in numerous applications. Designed specifically for harsh gas applications that have entrained liquids present or where condensate is expected to form, it is recommended that the pump head be pointed downwards to accommodate draining of these liquids.

  • condensate is expected to form, it is recommended that the pump head be pointed downwards to accommodate draining of these liquids
  • A special flange design makes the P2.4 and P2.84 designs suitable for hot applications. The flange is designed in two parts - one carrying the pump head is installed in a heated cabinet and the other carrying the electrical motor is flanged to the outside of the cabinet keeping the motor in ambient conditions.
  • The pumps employ explosion-proof motors. The ATEX models are suitable for Category 2. The AMEX models are CSA C-US approved and suitable for Class I Division 2.
  • For easy installation, a support console with vibration dampers is included for the P2.2ATEX,P2.2AMEXand P2.82AMEX.
