A pump was sought for conveying quick-drying glue through a two-stage filter system. The previously installed compressed air membrane pump was having problems with the valve ball malfunction. Hose pumps were also having trouble in the same application with hardening particles. Pumps with mechanical seal are not suitable for this medium. The downtime of the double-acting mechanical seal was unacceptable.
Installing the Boerger Rotary Lobe Pump with multi-seal-K meant that the service life of the rotor and shaft seal reached over 6000 hours under the challenging conditions of batch operation.
