Pump head EW-77390-00

PTFE pump head uses 4- or 6-mm OD rigid PTFE-tubing sets—PTFE tubing is the only wetted part, ensuring fluid purity and excellent chemical compatibility. Delivers a wide range of flow rates at pressures up to 100 psi (6.9 bar). Ideal for applications such as filtration, chemical injection, or high-purity sampling. Six-roller pump head with adjustable occlusion—tighten occlusion for higher pressure, loosen for longer tubing life. Transfer liquid containing small particulates. Compatible with L/S drives that accept two or more pump heads (1/10 hp minimum); for best results operate at 1 to 300 rpm.
