Parquet and tile adhesive

A manufacturer of paint, varnish and special chemicals needed a high performance pump to convey adhesive for tiles and parquet. The manufacturer previously used a piston diaphragm pump for this purpose. However, the capacity of the piston diaphragm pump rapidly dropped with the increasing viscosity of the pumped medium. The piston diaphragm pumps also generated high energy costs. 

Because of the negative experience with the membrane pump, the chemical manufacturer wanted to test an alternative pump extensively before purchasing. The customer agreed with Boerger GmbH to an eight week test phase. Due to the very demanding characteristics of the pumped medium, a Boerger Protect Rotary Lobe Pump was installed with double-acting mechanical seal. The pump is pressurized by a Boerger thermosyphon system. The Boerger Protect transfers the adhesive from a mixer into a storage tank or to their bottling process. During the transfer to bottling, a low pulsation and even transfer is essential. 

After extensive testing, the customer accepted the machine and is now completely satisfied with the Boerger Protect Rotary Lobe Pump. Pump capacity could be boosted by more than 150% with the Boerger Protect, compared to the piston diaphragm pump previously installed. Energy costs have dramatically reduced.
