I Application
The SLR pump is a positive displacement lobe rotor pump of a sanitary design suitable
for use in the dairies, food-processing, beverage, cosmetics, pharmaceutical and fine
chemicals industries.
This pump is perfect for managing all kinds of fluid, of either low or high viscosity, as
well as for filtering and bottling applications. Products containing fragile solids such as
junket can be pumped without damage thanks to the specially designed lobes.
I Operating principle
The SLR pumps basically consist of two lobe rotors which rotate synchronously inside a
casing without touching each other.
As the rotors rotate, the spaces between the lobes and the casing are successively filled
with the product, which is transported to the discharge nozzle with a fixed amount of
displacement.
The pumped fluid forms a continuous stream thanks to the tolerances between the lobes
and the pump casing, thus ensuring an efficient pumping.
