Rotho Peristaltic Pumps

Peristaltic Pump Principle

Rotho 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.
