Abrasive Products
The Rotho
pump is excellent on abrasive slurries where it has hadmuch more success than other
pumps. The Rotho
pump parts stay
out of the product zone and the hose is the only one thing that is in
contact with the product, this keeping abrasive wear to a minimum.
Products that crystallize are also well pumped by the Rotho
pump.
There are no valves or glands so the eventual build up of crystals
could not clog the
pump.
Corrosive Products
With corrosive fluids the hose selection is of paramount importance
to the longevity of the
pump. With the correct hose selection and no
other contact mechanical parts in the product, this ensures a long
pump life.
Fluids With Solid Parts Or Sensitive Products
A problematic product for many
pump types is fluids with solid
particles such as waste water with gravel, pieces of wood, concrete
or foods, where as the
peristaltic pump due to free tube-passage
can easily transfer it without any product or
pump damage. The Rotho
pump is also a good choice for transferring shear-sensitive
fluids or foamy products, the non emulsifying action minimises
damage to the product or its consistency.
Viscous Products
The Rotho
pump gives a strong self-priming suction which can draw
almost full vacuum, producing the pull necessary to draw viscous
materials such as honey, grout, resins or waste sludge, which is
almost impossible for many other
pump types.
Environmental Applications
There are two main environmental applications for the Rotho
pump:
- Chemical metering - Sludge transfer 1) Chemical metering: The most common is for Sodium Hypochlorite, Sodium Bisulfite, Ferric
Chloride and some polymers, as well as lime slurry and carbon slurry. Above
all with sodium hypochlorite that emits off gas, the Rotho
pump doesn’t loose
efficiency due to pockets of air, pumping together both liquid and gas 2) Sludge: The Rotho
pump can handle many different kinds of sludge depending upon
the level of treatment in a plant. It can feed and transfer thickened sludge,
waste activated sludge, return activated sludge and corrosive sludge.
