ELRO Peristaltic Pumps

ELRO peristaltic pumps are equipped as a standard with a patented vacuum system. It leads to many economic and technical advantages such as:

  • Very good suction properties up to 9.5 m / 31 feet lift (no additional suction equipment required.
  • Constant pump capacity during the entire hose life.
  • Enables the hose to reform to its full cross section.
  • Low reduction in capacity when handling viscous media.
  • Use as early warning system for a just in time hose exchange.

What Is A Peristaltic Pump?

The Peristaltic Pump is a positive displacement pump first invented by heart surgeon Dr. Michael DeBakey while he was a medical student in 1932. The design has essentially remained unchanged but the applications it can be used for have increased. It is built to pump various fluid types in differentmarinemarinaindustrial and even medical environments. The fluid is contained within a flexible tube fitted inside a circular casing as a rotor with 'rollers', 'shoes' or 'wipers' compresses the tube. When the rotor turns, the tube under compression closes forcing the fluid being pumped to move through the tube. As the tube opens to and returns to its starting state after the passing of the cam fluid flow or "restitution" is induced to the pump. The resulting process is called peristalsis
