New pump head material for selected KNF LABOPORT® FT pumps
Thanks to the optimization of the pump heads, the inner, wetted area is now equipped to transfer explosive atmospheres. LABOPORT® FT pumps equipped in this way are suitable for the equipment category 2G, and are thus designated for transferring gases, vapors or mists that create conditions in which the occasional formation of an explosive atmosphere is likely.
The precise ATEX approval only applies to ATEX II 2G IIB+H2 T3X internal atmosphere. The chemically resistant LABOPORT® pump models N 810.3 FT.18, N 820.3 FT.18 and N 840.3 FT18 are used in rotary evaporation, filtration, degassing, gel drying, vacuum concentration and liquid aspiration by a vacuum.
The dense polymer structure with few voids sets this new PTFE material apart and provides the basis for very robust performance during variations in load and temperature.
In addition, the material forms a smooth surface structure, which increases chemical resistance.
- Internal ATEX pump : ATEX 기준인 ATEX II 2G IIB+H2 T3X를 만족
- 내부 Chemical resistance 강화
- 내부 Mechanical 특성 강화
