Moving animal waste sludge can be a difficult proposition for pumps. It can be thick and corrosive and is definitely only a job for the right pump.
An Iconic Australian Food Manufacturer was looking for a liquid foods pump. They recently took possession of one of the more unusual Rotho Peristaltic pumps to function in their food manufacturing process. The model is MOD. PSF 1D which as can be seen from the photograph is a dual pump driven by a single motor and gearbox.
The Ragazzini Rotho range of positive displacement peristaltic [hose] pumps have a “roller on bearings” design so that the pump housing does not need to be filled with lubrication fluid, making them safer and easier to maintain.
