Peristaltic pumps PCM Delasco™

Large savings in maintenance costs
The peristaltic PCM DelascoTM pumps are positive displacement pumps based on the ability of a soft hose to deform and then retrieve its original shape. They cover a wide range of industrial applications, in particular where flexibility and maintenance are required.

They operate using the principle of peristaltic motion to pump fluid through a tube in the same way that blood, food and oxygen are transported into the human body.

A hose is fitted against a roller, which, when rotated, pushes a part of the hose. The pressure in this section is released as the rotor rotates and the hose retrieves its original shape, momentarily creating a vacuum that causes the hose to be refilled with liquid. The compression applied to the hose causes a temporary seal and as the rotor rotates, the pumped fluid is forwarded and displaced to the pump outlet.

The combined function of suction and depression results in a positive displacement pump which has the following advantages:

• The hose is the only wearing part of the pump
• There are no isolation valves and seals
• Self priming capability
• Management of corrosive and abrassive fluids
• Management of delicate materials
• Suitable for use with dry and solid particles in the pumped fluid
• Dry operation without damage

Delasco™ DX Series
