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 different marine, marina, industrial 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.
Features & Benefits

Specific Information About Our Peristaltic Pump
Ports Right Hand Side
The IP Series peristaltic pump may be adapted to existing installations by a modification of the port configuration. This only requires the relocation of the stainless steel pipe connections on the suction and discharge side of the vacuum system to suit the desired condition. This can be done without any additional machining.

Peristaltic Pumps Early Warning System
The patented early warning system (see illustrations 2 and 3) works as follows:
Each hose is provided with a small additional channel through which the air in the upper section of the pumping chamber is evacuated from the pump housing. Therefore, a vacuum is formed in the sealed aluminum housing. In the case of damage or normal wear of hose, the vacuum will drop.
The early warning can be seen through the installed vacuum gauge. An acoustic or optical signal can be activated by using the vacuum switch (see illustration 1).
By this the hose condition is monitored for optimum service planning.
Downtimes through normal wear can be predicted.
