A dairy factory approached Pump & Valve with a requirement to replace an existing lobe pump that was pumping a hot, viscous food grade slurry at medium solids at an above normal pumping pressure. The existing lobe pump was unreliable and often had stainless steel pickup on the lobes from high pressure deflection. Also during CIP flows the lobe pump would vibrate so badly that it sounded like there was an earthquake occurring in the factory! Furthermore when the slurry cooled it would get very sticky which presented mechanical seal issues. This pump was one of the main pumps in the factory and reliability was absolutely essential – if this pump didn’t run the whole factory went into limp mode.
