Rotho Peristaltic Pumps
Peristaltic Principle
A rubber tube is sqeezed along its length by rollers/shoes that push the fluid contained within. The pump incorporates a rotor with the rollers/shoes mounted on it which continually rotates, compressing and relaxing the tube. It is this action which moves the fluid through the tube with a constant rate of displacement for each revolution of the rotor. This gentle pumping action doesn't cause any damage to the product.
The fluid only comes in contact with the hose and not with any rotating parts, so the pump is very suitable for abrasive and corrosive applications. The tube's ability to reform after squeezing produces a vacuum that draws fluid into the tube, so very viscous liquids can also be pumped without problems.
The Rotho Unique Design
The “roller on bearings” design of the Rotho pump 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 lubricant 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.
