A Peristaltic Pump, also commonly known as tubing pumps or roller pumps, are a highly versatile option for many applications, including shear-sensitive fluids, abrasive fluids, and those containing hard solids. No matter whether you have an industrial or sanitary application, Tapflo UK’s range is available in both high and low-pressure options and covers CIP and ATEX requirements. In this guide, we hope to answer some of the most common questions we get asked by new customers when interested in using a peristaltic pump for their application.
The working principle of a peristaltic pump and design means that they can be categorised as a positive displacement pump. These work by essentially enclosing a specific volume of fluid into the pumps hose tubing and then rotating the set of rollers within the motor section. This creates a vacuum for the liquid to pass through, pushing it to the discharge side.
This pump operation is also where peristaltic pumps get their name from. The term “peristalsis” originates from the biological sense where muscles contract in our stomach to allow food to push through. A similar process happens when a peristaltic pump is in operation to allow for a variety of applications to enter the pump and effectively be passed through to the suction side of the pump, allowing more fluid to continue to enter from the pump casing.
Peristaltic pumps are an excellent option for fluids that need to be kept clean and sterile, such as food and drink applications, due to no contamination occurring in the pump. This is due to the interior tubing being the only part of the pump to come into contact with the application being pumped making the risk of bacteria growth very minimal. They are one of the most versatile pump options on the market with their ability to pump anything from beer, syrups and shampoo to waste sludge and molasses.

If you use a Peristaltic Pump for your application, you won’t have to worry about unwanted downtime for maintenance due to their durability and long life they provide, making them a highly efficient option. They are also able to run on a continuous basis or during specific operating times depending on your requirements.
Peristaltic Pump Hoses
The peristaltic pump tubing is one of the key components that will benefit from being of high quality to ensure it lasts as long as possible. Tapflo supply hoses that are manufactured from 2-6 individual layers of braided polyamide, which are compressed together ensuring long life and keeping your spares costs down. Investing in peristaltic tubing could save you time and money in the long run and reduce your financial headache, what an improvement!
If you’re looking for additional information on the hoses that Tapflo supply, you can read all about your options in Peristaltic Pump Options.
The hoses that Tapflo supply will also fit the majority of other Peristaltic Pumps on the market, so if you’re not quite ready to let go of your current pump for one supplied by Tapflo, we should be able to supply you with hoses, and if you’re not sold after using one of those then you obviously need to read one of our other articles about Peristaltic Pumps!
The sealless design of a Peristaltic Pump means that the only part of the pump to come into contact with your application is the hose inside, this, therefore, reduces the risk of leakages and maintenance costs! Purchasing a Peristaltic Pump with a sealless design ensures that you will be less likely to have to deal with your pump being out of action or requiring lots of maintenance. Typically, pumps constructed with seals, vanes and valves, fail repeatedly or require high maintenance which is cost-effective and time-consuming.
Using a Peristaltic Pump will leave you less worried about leakage, which will save you time and money. In fact, if the hose on your pump does rupture, your pump still won’t be damaged because the pump’s gearbox is protected by a lip seal, which will take the damage rather than allowing the product being pumped to penetrate the pump’s gearbox. This is just one of the advantages of a Peristaltic Pump because it’s only the hose that comes into contact with the product being pumped. So why worry with another pump brand, when you could have a stress-free Peristaltic Pump
They can handle a large variety of applications, ranging from shear sensitive and abrasive fluids, and those containing hard solids. They can operate at low and high pressures for transfer applications, as well as the ability to be used for dosing and metering with aggressive, pure, neutral, low or high viscosity liquids. This means that if the parameters of your application change, it’s more than likely that you can continue to use your Peristaltic Pump.
When it comes to peristaltic pumps, their efficiency is dependent on a whole variety of factors. With every customers requirements being different, you will have variables such as hose tubing size required, flow rate, max pressure and viscosity of application.
Often, when higher efficiency is required, multi-channel peristaltic pumps are recommended to enable one motor to drive a pump head with multiple channels each holding separate tubing.
