We have been manufacturing pumps for over 60 years, and from the early years we have especially focused on the research and development of the peristaltic pump. Today we are in a position of proposing solutions for every industrial field with the reliability and quality that we have built our success upon.

Simple Principle The basic principle of the peristaltic pump traces back to human “peristalsis” a term referring to the alternating contraction and relaxation of muscles around a tube to force the contents through it. An elastomeric tube is squeezed along a length by rollers that push the fluid contained within. The tube’s restitution after squeezing produces a vacuum that draws fluid continuously into the tube. This creates a gentle pumping action that doesn’t cause any damage to the product. Contaminations are avoided because the fluid is contained within the tube (one contact part with product)....

No seals No valves Self priming Only tube to replace Reverse flow by reversing motor No contact between product and mechanical parts Can run dry without damage Able to pump products with solid parts inside Chemical Water and waste treatments Food & beverage Uses Transfer, feed, meter, filter of: Fragile or sensitive fluids Metallurgy Pulppaper Compound fluids Abrasive and corrosive fluids Non pollutable or pollutant fluids Painting and pigment Ink Mining Marine Biogas

Abrasive Products The Rotho pump is excellent on abrasive slurries where it has had much 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...

ROTHO tube It is an elastomeric tube right for duty service and its selection depends by the product to pump, pressure, temperature; it is a multilayer hose with 2, 4 or 6 textile insert reinforcement depends by its dimension and pressure to win.

Pulse dampeners The pulse dampeners are suggested in case of negative suction and pressure over 2 bar; they ensure a better pump working and a longer tube life. Three types are available: Empty vessel Flexible tube

The models of MS and SDF Serie can be equipped of feeder to feed products with solid parts or sensitive parts. All Rotho pumps (optional for PSF Serie) are equipped of leak detector to provide early indication of hose failure. This is a float type sensor that is located at the lowest point of the pump housing. Leak detector The “retractable” position of the roller is instrumental in increasing the lifetime of the tube element. When the pump is not in use for a certain period of time, the tube element can be separated from the roller from outside the pump by activating the rapid release mechanism...
