More About this Item

The PTFE tubing pump head is ideal for applications such as filtration, chemical injection, or high-purity sampling. It is compatible with L/S drives that accept two or more pump heads with a 1/10 hp minimum. For best results operate at 1 to 300 rpm.

PTFE pump head uses 4- or 6-mm OD rigid PTFE-tubing sets—order PTFE-tubing sets separately. The 4 mm OD tubing set has a flow rate of 0.06 to 17 mL/min at 1 to 300 rpm while the 6 mm set has a flow rate of 0.25 to 65 mL/min. This pump head uses Masterflex® PTFE-tubing sets 77390-50 and 77390-60 only.
Note: do not pump gases or run dry for extended periods; run dry to prime only.
