Double Diaphragm Pumps for Chemical Applications

With the new tim®CHEM series timmer is expanding the application range for their products to critical chemicals. The company starts with four pneumatic double diaphragm pumps, which offer many advantages in terms of efficiency, application possibilities and availability. 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. Now timmer offers the pumps 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 conveying capacities range from 60 up to 600 l/min.

Reducing energy costs and increasing lifetime

The extremely smooth-running ceramic valve is the heart of the pumps and has already proven itself in many other applications. It is not only virtually wear-free, but also enables a safe start-up with low starting pressure as low as 0.7 bar over the entire lifetime. This also opens up very good application possibilities in the field of dosing.

Low maintenance effort

The stability does not come at the expense of easy and quick disassembly, thanks to the innovative tim® FIX connecting elements. Even essential parts such as the media valves are accessible without special tools. However, maintenance is rarely necessary. This is because the short-stroke diaphragm has a much longer lifetime than the diaphragms used in many conventional chemical pumps that operate with a longer stroke. In general, timmer sees an advantage in opting for short-stroke diaphragms – besides the considerably longer lifetime – also due to the even, low-pulsation media flow. Since all models of the timCHEM series require only four O-ring seals with the same dimensions on the outside, both maintenance and expenditure are considerably reduced while leakage safety is increased.

Optionally, operators can monitor various parameters such as number of strokes and stroke frequency, operating time, diaphragm condition, etc. For the chemical industry all pumps are certified according to the ATEX directive.
