A Brief Guide to Peristaltic Pumps

Peristaltic pumps are used in many applications where other pumps wouldn’t guarantee safety or purity of the materials being pumped. This is because the pumping mechanism is outside of the tube which is used to transport materials. They are named peristaltic pumps after the digestive mechanism of humans and nearly all animals, called peristalsis.

The best illustration of peristalsis in the human or animal world is when a snake eats a mouse. The snake swallows the mouse and sets of muscles start contracting toward the back of the snake, pushing the mouse through the snake’s digestive system. This is how we swallow and how all mammals and reptiles swallow.

In a peristaltic pump, the pump is pinched by “shoes” or rollers that compress the tube in the direction the fluids are intended to flow. As the tube closes, it forces the fluids forward through the tube. Also, as the part of the tube behind the roller opens back up, it creates a vacuum and encourages fluid to flow into the tube via a partial vacuum.

Applications of Peristaltic Pumps

Peristaltic pumps are used in a variety of industries for a variety of specialty fluids. Peristaltic pumps can keep sterile fluids sterile and keep aggressive fluids from damaging equipment. They are used to pump IV fluids, slurries with high concentrations of solids, aggressive chemicals and other fluids that must be kept from the outer environment.

A Brief Guide to Peristaltic Pumps

Medical Uses
During open heart surgery, peristaltic pumps are used in the heart-lung machine to reduce hemolysis. They are also used in dialysis machines and in medical infusion pumps.

Testing and Research
Peristaltic pumps can also be used as carbon monoxide monitors, in analytical chemistry experiments and for dosing due to their extreme accuracy.

Agriculture
They are also used to extract maple tree sap in configurations called “sapsucker pumps.”

Other Uses:
Peristaltic pumps are used for food manufacturing, chemical handling in the printing, pharmaceutical and laundry soap industries. They are used in engineering and manufacturing applications such as pulp and paper plants. They are also common in water and wastewater treatment and for sewage applications.

Pump Applications in the Medical Industry

Since 1990, we have supplied vacuum pumps and numerous varieties of water pumps in Perth and across Australia. Here are some medical uses you may or may not know about.

Air Mattresses

Medical grade air mattresses have individual coils to adapt to patients, helping to protect them from bedsores.

Aspirators

Aspirators are modified diaphragm pumps used to remove debris, fluids or tissue from injury sites. These are most commonly used for surgery.

Autoclaves

Vacuum Pump for Medical Industry

Autoclaves are used for sterilisation with vacuum pumps used to evacuate the chambers.

Blood Analysers

Blood analysers provide real-time readings when time is of the essence. They can measure glucose, white blood cell count and medication levels. Compressed air is used for many of the processes.

Compression Therapy

Compressed air is used to fill compression chambers.

Dental Carts

The cart that sits between the dentist and the patient needs vacuum and compressed air for its various functions.

Dialysis Machines

These replace the kidneys and filter all of a patient’s blood during one sitting. A peristaltic pump is used to move the blood.

Nebulisers

A nebuliser uses an air compressor to turn medications into a fine, breathable mist.

Nitrogen Generators

These convert compressed air into dry nitrogen to supply medical instruments.

Oxygen Concentrators

These use compressed air and convert an ambient oxygen count of 21% to one approaching 99.5%.

Respirators

These are worn by doctors, nurses and other personnel, especially in operating rooms. They protect both the medical personnel and the patients.

Wound Aerators

These provide controlled pressure to wounds and help speed healing by increasing the amount of oxygen to the wound site.

An Introduction to Filter Technics Pumps and Filters

Filter Technics pumps and filters are designed specifically for industrial filtration. Filter Technics is based in Belgium with branches located throughout Europe. They have been serving the filtration needs of industry since 1992. In that time, they have become recognised as a “one stop solution” to industrial filtration needs.

They offer a concept called “Total Filtration Management,” in which all service and logistics are handled by Filter Technics. Their purpose is to simplify the purchasing process, lower the total cost and ensure that every aspect of your filtration system is optimally maintained and kept fully up to date in technology and compliance.

Filter Technics Pumps and Filters

Our Filter Technics Pumps and Filters Selection

Filter Technics is the world leader in filtration systems. They not only make filters for their own pumps, but they make filters for virtually every major pump brand in the world. We can obtain any Filter Technics product, but since filters need replacement more often than pumps, we handle a lot more of their filters.

Vacuum Pump Air Filters

Vacuum pumps are built to process air by either decreasing the pressure or compressing the air. It is important that the filtration process is reliable to keep moving parts from being damaged. Dust or any other solid particles in the air can seriously shorten the lifespan of a blower or a vacuum pump. Filter Technics air filters are not only fully interchangeable with most manufacturers’ products, they provide superior performance.

Oil Separators

Oil separators are used in “oil flooded pumps.” After the pump has processed oil, they separate air from the oil. Then, they release the air into the atmosphere as the oil is recirculated for further use. Oil separators also remove solids that can contaminate oil.

Complete Filters

Complete filters are used for vacuum pumps and include both the housing and cartridge.

Vacuum Pump Varieties and Applications

The vacuum pump is one of the more common pumps because so many different pumps are classified as vacuum pumps. A vacuum pump is a pump that creates a partial vacuum which moves air or fluids. Air or fluids rush into a vacuum because both air and water move from places of high pressure to places of low pressure.

There are three types of pumps that are classified as vacuum pumps: momentum transfer pumps, positive displacement pumps and entrapment pumps. For most applications, positive displacement pumps will suffice. In rare or extreme instances, positive displacement pumps can be enhanced by adding momentum transfer or entrapment pumps to work together with positive displacement pumps.

Vacuum Pump Varieties and Applications

A positive displacement pump works on the principle of creating a vacuum chamber into which fluids are drawn. The liquid is ejected from the chamber and another vacuum is created, which draws more fluid. This is repeated at intervals to steadily pump liquids.

At Pump Solutions Australasia, we carry five basic kinds of vacuum pumps that are classified as positive displacement pumps: double diaphragm pumps, liquid ring pumps, rotary vane pumps, side channel pumps and blowers. Here is a brief view of each.

Air Operated Double Diaphragm Pumps (AODD)

AODD pumps create a vacuum by using diaphragms to create a vacuum and then discharge product. They are relatively inexpensive pumps that are used for many different areas of industry. They can be used to pump water, acids or slurries. They are also used in food processing because their design makes them appropriate for use in situations where sanitation is mandatory.

Double diaphragm pumps are extremely versatile. They can be used to pump fluids on oil tankers or to make artificial hearts. We carry a full line of RAN diaphragm pumps, imported from RAN Pump in Turkey.

Liquid Ring Pumps

Liquid ring pumps are used as vacuum pumps but also as gas or air compressors. Among their many applications, they are used to extract the water from press felts and dewater the pulp slurry on paper machines. They are also used to vacuum-form molded paper pulp packaging such as egg cartons. They can be used for soil remediation, vacuum distillation for petroleum refining and in vapor recovery systems.

We carry a full line of Speck Pumpen liquid ring pumps for numerous applications.

Rotary Vane Pumps

A rotary vane pump uses a rotor inside a cavity with vanes mounted to it. They are used in motor vehicles for applications that require high pressure hydraulic pumps, including power steering, automatic transmission and supercharging pumps. They are very popular in the food and beverage industry for uses such as espresso coffee machines and carbonators used in soft drink machines. They can also be used for propellants, aerosols, aviation fuel transfer, refrigeration and solvents.

Side Channel Pumps

Side channel pumps are used in gas and vapour handling. They are used in all applications where low NPSH is mandatory. We carry a full line of Becker side channel pumps in single stage or double stage blower/vacuum models.

Blowers

For the sake of simplification, using a blower is like using a vacuum pump backwards. The same process can move air in both directions. Thus, blowers are classified as vacuum pumps. As with side channel pumps, Becker is our manufacturer of choice for blowers.
