At Silkem, the zeolite was pumped to the tower dryer with a screw pump. Because the pump operates almost every day of the year and due to the material that the screw pump pumps, the stator and rotor of the screw pump wear out quickly, which causes high maintenance costs on an annual basis. So they are in the company Silkem was looking for a better alternative to reduce maintenance costs on an annual basis. When looking for a better alternative, they came across a diaphragm pump SG 130 – 2 DS17, and based on the presentation of this diaphragm pump through videos and specifications, they decided to buy this diaphragm pump. When the current screw pump was replaced with the SG 130 – 2 DS17 diaphragm pump, a number of
problems arose.
