A PTFE diaphragm permits compact construction of this diaphragm pump, and offers cost savings for high-pressure applications. A patented pressure-supported diaphragm-fixation system is used, so that the fixation is structurally prevented from expanding during the pressure stroke. No auxiliary seal is thus required — even at pressures up to 1,000 bars. The M800 pump head with PTFE diaphragm is used in the ecoflow and triplex series, which handle flowrates between 0.1 and 1 m3/h per pump head; viscosities of the medium up to 100,000 mPas; and temperatures between –20 and 80°C. — Lewa GmbH, Leonberg, Germany
