With the new pump series timChem, which according to the manufacturer offers many advantages in terms of efficiency, application possibilities and availability, Timmer extends the range of applications to critical chemicals. Since June 2020, the portfolio launched at the beginning of the year has been complete for the time being with the addition of further sizes. The pumps are available in ½-, 1- and 2-inch versions made of PTFE or PE, as well as a 2-inch version made of cast stainless steel (V4A). The flow rates range from 60 to 600 l/min. The very smooth-running ceramic valve is virtually wear-free, and also enables safe starting with low starting pressure from 0.7 bar over the entire service life. A new material-suitable design of the plastic housings, especially the PTFE versions, ensures a high degree of stability of the housing components over the long term. Innovative connecting elements ensure simple and quick disassembly. Even essential parts such as the media valves are accessible without special tools. The short-stroke diaphragm has a much longer service life than the diaphragms used in many conventional chemical pumps that operate with a longer stroke. Since all models of the series use only four O-ring seals with the same dimensions, maintenance and costs are considerably reduced while leakage safety is increased. Optionally, operators can monitor various parameters such as number of strokes and frequency, operating time and diaphragm condition.
