Paper Residues

The peristaltic pump’s ability to run dry with no adverse effect gives it an advantage for many applications. One is in paper manufacture. It is an industry that also processes a large amount of waste water that can contain residues such as fibrous substances, fillers and chemicals. As the fluid tends to clog when only low flow rates are needed, the efficient working of other pump types is compromised. The low maintenance credentials of a peristaltic pump make it the perfect choice. When the fluid clogs at the suction side, as can happen easily with this application, the simple reverse action of the rotor is the easy solution to the problem.

Bubble-Free Ink

Ink handling is another growing application area for peristaltic pumps. A good example in this sector comes from a packaging company that had been using air diaphragm pumps to transfer ink from storage containers to printing machines. However production problems were resulting from the existing pumps’ inability to handle the water-based ink gently enough. As a result, bubbles formed in the ink, ruining the packaging, creating waste and adding expense.

A compact peristaltic hose pump proved to be the ideal solution. Ink is dosed gently, eliminating bubbles and as the ink is completely contained within the pump’s hose throughout the process there is no mess or wear to moving parts. Color change is quickly accomplished as the hose is easily exchanged. The pump itself can even run dry without fear of damage.

Yeast Pumping

Pumps with a high shear-rate can damage a fragile product such as yeast and compromise its quality. This can lead to reduced production efficiency. The viscosity of yeast can also vary significantly during a typical production run, going from the consistency of water to several thousand Centipoise and this can cause problems for some pumps.

Additionally, the abrasive nature of yeast can lead to stator or impeller wear resulting in costly downtime, loss of production and ongoing maintenance costs. Another common pumping problem is the result of active yeast producing gas. This can also cause some pumps to vapour lock, reducing output. All of these issues are easily resolved with the use of peristaltic pumps that are able to handle viscous and abrasive media with a low shear pumping action and are not susceptible to vapour locking.

Drug Administration

At the lighter duty end of the scale peristaltic tube pumps are proving popular for accurate and reliable dosing. A typical application is a fast and automatic method of administering methadone to recovering drug addicts. Indeed a key benefit of the system is the elimination of human error as an incorrect dose of this substance could prove fatal to the patient. The design of the peristaltic pump internal backflow for accurate dosing without slip and ensures the high degree of repeatability required by legislature such as The Medicines Acts within the UK.

Hygienic dispensing is guaranteed as the methadone is contained fully in the tube which was specified to be resistant to the methadone’s acidity. The simplicity of the pump design makes it easy and quick to exchange the tube in the pharmacy. No special tools or training is required and the used tubing can be safely disposed of.
