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.

These sample pumps are equipped with a 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

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

FM C-US approved and suitable for Class I Division 2.

For easy installation, a support console with vibration

dampers is included for the P 2.2 ATEX, P 2.2 AMEX and

P 2.82 AMEX。
