The basic principle of the peristaltic pump tracesback to human peristalsisӔ 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 tubes restitution after squeezing produces a vacuum that draws fluid continuously into the tube. This creates a gentle pumping action that doesnҒt cause any damage to the product. Contaminations are avoided because the fluid is contained within the tube (one contact part with product). The pump employs a rotor with rollers mounted on it that continually compress and occlude some portion of the tube. This action moves the fluid through the tube with a constant rate of displacement for each revolution of the rotor, enabling a precise measurement of the volume of fluid pumped through the tube. > The roller on bearingsӔ design of the Rothopump offers many advantages: -It eliminates the requirement for adding a lubrication fluid inside the pump housing, because there is no friction on the surface of the tube therefore giving a longer tube life. -They can transfer food products with no contamination hazards, as the pump housing is lubrication free.-With no lubrication fluid required, hose replacement is greatly simplified and cheaper without having to drain and dispose of a messy and possibly contaminated oil or glycerine solution. >

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. > 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...

It is an elastomeric tube right for duty service andits 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. >

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. This device helps the pump to suck viscous and thicky products. Feeder Leak detector Vacuum system >
