A peristaltic pump is a type of positive displacement pump that operates using a mechanism known as peristalsis.

In simple words, peristalsis is the natural squeezing and relaxation motion that occurs in biological systems, such as the way the human digestive system moves food along the intestines.

In a peristaltic pump, this concept is applied mechanically to pump fluids. The pump typically consists of a flexible tube or hose, often made of materials like silicone or other elastomers, which is placed within a circular pump casing.

The pump casing usually has rollers or shoes that press against the tube and create a squeezing or compressing action. As these rollers move along the length of the tube, they force the fluid within the tube to move in the desired direction.

We have also written an in-depth guide on what is a peristaltic pump and the essential guide to peristaltic pump tubing.

Here's how a peristaltic pump works through two phases:

  1. Squeezing Phase: As the rollers or shoes press against the tube, they squeeze the fluid and create a temporary closure downstream of the pump preventing backflow, aka pressure phase.

  2. Relaxation Phase: As the rollers move away from the squeezed portion of the tube, the tube regains its shape and creates a vacuum, drawing more fluid into the pump from the upstream side, aka vacuum phase.

This pumping action is continuous and creates a gentle, pulsating flow of fluid through the tube. You should also keep in mind that the tubing could wear out with time, so it needs to be replaced later on.

Peristaltic pumps are known for their gentle handling of sensitive fluids, as the fluid only comes into contact with the interior of the tubing and not the pump itself. This makes them suitable for applications in industries such as pharmaceuticals, biotechnology, food and beverage, water treatment, and more.

Peristaltic pumps offer several advantages:

  • They can handle viscous, abrasive, and shear-sensitive fluids.
  • They provide accurate and repeatable flow rates.
  • They offer excellent hygiene and sanitation as the pumped fluid only contacts the tubing.
  • They can operate dry, meaning the pump won't be damaged if it runs without fluid temporarily.
  • They are relatively low-maintenance compared to some other pump types.

These pumps find use in various applications, such as dosing and metering chemicals, transferring fluids in medical devices, pumping food products, and more. When considering a peristaltic pump for your specific application, it's important to choose the appropriate pump size, tubing material, and other specifications to ensure optimal performance.

Peristaltic Pumps For Rent - Choosing The Right One

When choosing the best peristaltic pump to rent, it is important to consider the following steps:

  1. Search Local Suppliers: Look for equipment rental companies in your local area or region that specialize in industrial or scientific equipment rentals. You can use online directories, search engines, or industry-specific platforms to find potential suppliers. We at Spectra Scientific offer the best industry-standard peristaltic pump Field Pro 3.

  2. Contact Suppliers: Reach out to the identified suppliers and inquire about their peristaltic pump rental offerings. You can ask about availability, rental terms (daily, weekly, monthly rates), delivery options, maintenance, and any additional services they may provide.

  3. Specify Your Needs: Clearly communicate your requirements to the supplier. Provide details about the intended application, flow rate, tubing size, and any other specific features you need in a peristaltic pump. This will help the supplier recommend the right pump for your needs.

  4. Request Quotes: Obtain quotes from multiple suppliers to compare rental costs and terms. Make sure to inquire about any potential additional charges such as delivery, setup, maintenance, or insurance.

  5. Review Rental Agreement: Carefully review the rental agreement provided by the supplier. Pay attention to terms and conditions, rental duration, costs, liability, and insurance coverage. Ensure you understand and agree to all terms before proceeding.

  6. Arrange Delivery and Setup: Once you've selected a supplier and agreed to the terms, coordinate the delivery and setup of the peristaltic pump. Provide any necessary site-specific information to ensure a smooth setup process.

  7. Usage and Maintenance: Follow the manufacturer's guidelines for proper usage and maintenance of the peristaltic pump. This includes ensuring the correct tubing is used, regular cleaning, and adhering to safety precautions.

  8. Returning the Pump: At the end of the rental period, arrange for the pump to be returned to the supplier as per the agreed-upon terms. Make sure to clean the pump and any accessories before returning them.

Remember that peristaltic pumps are commonly used in various industries, including pharmaceuticals, food and beverage, water treatment, and scientific research. Make sure to choose a pump that meets your specific requirements and consult with the supplier if you have any questions or concerns.

Please note that the availability of peristaltic pump rentals and specific details may vary depending on your location and the suppliers in your area. Make sure to conduct thorough research and communicate directly with potential rental providers to get the most accurate and up-to-date information.

At the end of the day, do make sure the peristaltic pump you are choosing to rent is reliable enough to get your work done efficiently.
