Glycerine residues

A manufacturer of oleochemical additives and consumables was looking for a pump for conveying glycerine residues. Due to the viscosity and the high solids content of the medium, the centrifugal pump used so far had cavitation problems and, as a result, generated strong vibrations and running noises. Severe damage was caused to the mechanical seals and the impeller. The customer now uses a Börger Protect rotary lobe pump. The machine unit is operated continuously for 24 hours/day. During the process, the medium to be conveyed has a temperature of 80 to 145 °C and must not cool down. The suction- and pressure-side connections are heated. The Börger rotary lobe pump is equipped with a steam heater cover. It heats the pump casing.
