One
of the world's fastest growing pump type is Peristaltic Pump. A
Peristaltic Pump is used to pump clean or sterile fluids because the
pump cannot contaminate the fluid, or to pump aggressive fluids because
the fluid cannot contaminate the pump. Peristaltic pumps are also
referred to as flexible member pumps, flexible tube pumps, dispensing
pumps or dosing pumps, hose pumps or tube pumps. Peristaltic pumps are
being widely used in printing machines.Uses and Features of Peristaltic Pumps
- A peristaltic pump is used in printing industry to circulate ink during the process of printing.
- The pump can easily circulate ink, thereby saves time and cost.
- The pump is being extensively used for metering and scavenging inks and coatings.
- The pumps also help to remove the excess varnish for recirculation.
- Valves and seals are not needed as in other pumps. Hence, they do not require any maintenance.
- Peristaltic pumps come with wash down capabilities.
- Peristaltic pumps are also reversible and are generally used to clean out the hose or tubing.
- Single head and dual head pump options are available.
- The tubing in peristaltic pumps is disposable.
- When choosing between peristaltic pumps, flow rate is proportional to the rotation of the rollers.
- These pumps combine precise positive displacement and low maintenance requirements with the ability to handle abrasive and aggressive fluids, which wear out many other pump types. This unique combination of features makes it a cost-effective alternative for difficult pumping applications.
