KNF Laboport UN840.3 FTP Diaphragm Vacuum Pump (1.2 CFM)

The KNF Laboport UN 840.3 FTP is a premium, high-performance diaphragm vacuum pump engineered specifically for demanding chemical environments. Built for absolute reliability, this 100% oil-free, dry-running pump is the ultimate solution for transferring and evacuating highly aggressive gases and corrosive vapors without risk of contamination or premature wear.

At the core of the UN 840.3 FTP is its exceptional chemical tolerance. Featuring solid PTFE pump heads, PTFE-coated structural diaphragms, and FFPM valves, the entire wetted flow path is fully armored against chemical attack. This robust construction eliminates the need for frequent oil changes, minimizes downtime, and guarantees a long service life, making it a highly cost-effective asset for any modern chemistry or research laboratory.

Equipped with a dual-head system and integrated overpressure relief mechanism, it delivers a smooth, pulse-free flow. Its quiet operation, compact footprint, and environmentally conscious oil-free design ensure a clean, safe, and comfortable workspace for laboratory personnel.
