Pesticides

A customer manufactures active ingredients for pesticides in batch production: herbicides, fungicides and insecticides. The active ingredient is spun into crystals or liquid in centrifuges. This is where the Boerger Protect Rotary Lobe Pump is used.

In the start-up phase of the centrifuge, the ATEX compatible Börger Protect has to achieve a high pump output. After filling, the pump is run via a bypass to prevent crystallization in the pipe line. This is then driven with less power. Other pumps showed poor results with regard to the partly high temperatures and the crystals. This active ingredient is processed again into the finished product in a downstream operation using Börger Rotary Lobe Pumps (4 x Boerger Protect) and a dispersing machine.
