The piston dosing pump 5:1 PTFE is designed for the precise delivery of low-viscosity (liquid) materials. The PTFE seals are chemically resistant, also for moisture-curing and aggressive media. The mixing ratio can be adjusted via a rocker from 7:1 to 3.5:1; the maximum material pressure is system-dependent. Matching seal kit: 2000-0218-0500.
