Peristaltic Pumps are the “go-to” pump for handling highly viscous, corrosive and abrasive fluids. They have a simple design but can be customized to provide precise fluid flow to many important applications. Many of our Peristaltic Pumps are sold to OEM companies to incorporate into their medical and bio-science equipment, used in water treatment systems, used in printing products, or used for fluid testing in laboratories. But how do Peristaltic Pumps actually work?
Peristaltic Pump Process
- The Peristaltic Pump is a positive displacement pump where a flexible tube is fitted inside a pump casing
- Inside the pump casing is a central rotor with a number of rollers (lobes) attached
- When connected to power, the rotor turns and the rollers compress the flexible tubing
- Because of the design of the rollers, part of the tube will be under compression and part of the tube will be in a natural state
- As the tube is under compression, the fluid is pumped through the tube
- As the tube is in its natural state, the fluid is free to flow into the tube because a vacuum has been created
- This process is repeated, which pumps the fluid through the entire length of the tubing
This process is extremely efficient and we can see it working in our natural world. The process of peristalsis is used in our own gastrointestinal tract.
Peristaltic Pump Applications
Peristaltic Pumps can go by several different names, including positive displacement pumps, roller pumps, lobe pumps, metering pumps, and dosing pumps. There are many types of applications in many types of industries where Peristaltic Pumps are used:
- Medical Equipment
- Chemical Dosing
- Water Treatment Systems
- Vending Machines
- Printing Equipment
- Industrial Applications
- Laboratory Testing
The only replaceable component of a Peristaltic Pump is the tubing. The design is very simple, due to the fact that these pumps do not use any diaphragms, valves or seals which could be difficult to maintain and expensive to repair. The only part of the Peristaltic Pump in contact with the fluid being pumped is the inside of the tube. Therefore, only the composition of the tubing is considered for chemical compatibility. Due to the gentle pumping action, Peristaltic Pumps are an ideal choice for shear sensitive fluids.
Many Benefits of Peristaltic Pumps
- Effective at handling fluids containing particulates
- Will run dry for a very long time
- Can run in either direction without affecting the flow rate
- Very accurate and can be used as a Metering Pump – the accuracy and repeatability can be within 1% or better
- Due to the fact that the only replaceable component is the tube, the maintenance cost is very low compared to other types of pumps
- Careful selection of the tube, such as the use of Sterile tube make these pumps suitable for laboratory use in medical and bio-sciences requiring high hygienic standards without contamination
- Low shear induced from the pumping action
