Leading Peristaltic Pump Manufacturers

A peristaltic pump is a mechanical device that produces pressure by constricting motion along a tube (much like natural peristalsis). A roller pump is another name for a peristaltic pump. This pump is best used in medical, agricultural, and water treatment applications where a precise fluid volume is required. Read More…

Peristaltic Pump Peristaltic pumps are a unique type of metering pump that uses rollers to mimic the contracting and relaxing used in the gastrointestinal tract in order to move fluids from one place to another.

These pumps are employed in a variety of applications around the globe. They are employed in commercial, residential, and industrial settings. The peristaltic pump is one of the various types of pumps. The peristaltic pump is a well-known positive displacement pump used to move various fluids. The main focus of this article is on the peristaltic pump's various features.

A flexible tube attached to the circular pump's housing functions as the liquid reservoir in a peristaltic pump. Although linear peristaltic pumps are also offered on the market, the majority of peristaltic pumps work by rotation.

Around the pump's rotor, numerous "rollers" or "wipers" squeeze the flexible tubing as they rotate. As the compressed tube segment shuts, the liquid flows through the tube. As a result, more liquid draws into the tube when it naturally opens after passing the roller. Peristalsis, a phenomenon with numerous biological applications, including the gastrointestinal tract, causes this.

The peristaltic pump can run without stopping or be indexed by partial rotation to supply a small volume of liquid.

The liquid is pumped through a tube without contacting any pump parts. As a result, a peristaltic pump is an excellent option for moving liquids and chemicals without cross-contamination.

These pumps can circulate media within or pump it from the source to the waste. A pulsing flow is transferred via the peristaltic pump.

Different pumps will require a different amplitude and frequency of vibration to achieve a particular flow rate depending on the number of rollers, their rotational frequency, and the tube diameter. The most advanced peristaltic pumps are software-controlled and automatically execute routine injections and simple flow changes.

Peristaltic Pump Working Principle

A peristaltic pump operates on the positive displacement principle and is also known as a peristaltic tube or hose pump. The liquid is fed through the peristaltic pump tube by rollers that rotate and press the tube against the pump's casing. The volume of the roller rises as it turns and passes over particular areas of the tube, allowing more liquid to enter for the subsequent roller pass. There is no need for additional valves because the tube closes with at least one roller while operating. Complete closure of the tube results in a positive displacement effect when the entire tube is surrounded by track and rollers. Therefore, the check valve is not required when operating the pump since the positive displacement prevents backflow. Since only the flexible tube of the pump comes into contact with the liquid, these pumps work best with viscous and corrosive liquids. In addition, the pump is a maintenance-free component, whereas the pump head or tube can be readily replaced, according to the model.

Types of Peristaltic Pumps

The three types of peristaltic pumps are as follows:

  • Hose pumps
  • Microfluidic pumps
  • Tube pumps

Microfluidic Pumps

Biotechnology, pharmaceuticals, the biological sciences, and engineering systems frequently use microfluidic pumps. Microfluidic pumps regulate the flow of liquids and gases in the microliter range while transporting small fluid quantities.

Hose Pumps

Hose pumps are capable of pumping a wide range of liquids. The flexible hose or tube of the pump is alternately relaxed and compressed to do this, which is done by passing the tubing over rotating rollers or shoes. The content is absorbed and advanced through this procedure.

Peristaltic Pump Tubing

The peristaltic hose pump features a self-priming feature and may operate in dry environments. Therefore, it's unnecessary to always have fluid; one can start it dry and draw liquid into the tube. Doing this prevents the trouble of priming the pump before usage and decreases the possibility of mishaps. In addition, Industrial hose pumps have manufactured new multipurpose and multifunctional industrial pumps by incorporating cutting-edge technologies from abroad.

Features of a Hose Pump

  • This peristaltic pump has fewer parts to rip and wear out quickly.
  • No internal backflow, transfer in both directions
  • At high pressure, it is effective.
  • High solids content media (up to 75%) can be transported by this pump.
  • No mechanical parts, no valves, and a smooth flow
  • It is highly capable of stimulating itself.
  • Its upkeep is fairly simple.
  • The hose may be greased from the outside and can operate in dry situations. It might operate in some circumstances without user input. The technique lowers the cost of maintenance.

Tube Pumps

The optimum places for a tube pump are process areas, labs, and bench tops. Applications requiring lower flow rates can use these peristaltic pumps. They have a high head and can move vast amounts of fluid. These pumps are powerful. These pumps can handle viscous, chemically aggressive fluids and shear-sensitive materials, providing exact weighing and good reproducibility. In addition, this pump can produce the maximum amounts of hydrocarbons depending on the tubing size. Although the liquid load is more than the liquid load of the insert pump due to the big diameter of the piston, tube pumps can deliver high pressure while providing precise weighing and distribution.

Choosing the Proper Peristaltic Pump Manufacturer

To make sure you have the most positive outcome when purchasing Peristaltic Pumps from a Peristaltic Pump Manufacturer, it is important to compare at least 4 or 5 Manufacturers using our list of Peristaltic Pump suppliers. Each Peristaltic Pump Supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote.
