Hello to you and your readers at PII. I’m Steffen Knoedler, Global Business Development Manager – Food & Beverage at WMFTS and I’d like to speak directly to you about the next generation of clean-in-place (CIP) systems and how the new Bredel CIP pump from Watson-Marlow Fluid Technology Solutions (WMFTS) has been engineered to meet every demand across the hygienic process industries. Designed for applications where hygiene is non-negotiable, it delivers exceptional cleanliness, correct fluid velocity and outstanding chemical resistance.

In sectors such as food and beverage, cosmetics and pharmaceuticals, clean-in-place (CIP) systems are essential. Yet for breweries, finding a pump that fulfils all CIP demands; cleanliness, high fluid velocity, chemical resistance and long hose life, has long been a challenge.

That is now changing with the introduction of the Bredel CIP pump from Watson-Marlow Fluid Technology Solutions (WMFTS). This step-change in peristaltic pump technology has been developed specifically to meet the most stringent CIP requirements, ensuring the correct fluid velocity and extending hose life for optimum performance.

Why has WMFTS launched the Bredel CIP pump and what are its capabilities?

When we talked to engineering companies which design systems and solutions for breweries, they said the velocity requirement for CIP is 2.5 metres per second and it is becoming something their customers will not compromise on.

No hose pump in the world without a CIP feature can provide the 2.5 metres per second, so the engineering companies have always had to make a compromise.

But this is not the case with the Bredel CIP pump which has a new rotor to enable users to achieve the CIP cleaning velocity requirements. Automatic retractable shoes for cleaning allow the pump to be cleaned at the required fluid velocity. By retracting the shoes during cleaning, hose compressions within the CIP cycle at high temperatures are eliminated which extends hose life and reduces costs of replacing hoses.

Also, the chemical composition in CIP, especially acid, has gone up in the last few years which is more aggressive to the hose. On some customer sites we have seen hose life reduced by half due to the chemical combination with the temperature and the force on the hose when running CIP.

But Bredel hose pumps support efficient processes by enabling easy maintenance and maximising uptime, ideal for applications requiring CIP.
The Bredel CIP pump, available in sizes 20 (up to 600 L/h), 25 (up to 1,800 L/h) and 32 (3,200 L/h), is capable of automated CIP which makes it unique.

Is there such a thing as the perfect pump for CIP applications, whether in breweries, other food and beverage facilities and sanitary applications?

With CIP there are two challenges for pumps. The first challenge is whether the pumps are really clean after CIP. Diaphragm pumps are never clean after CIP due to their internal design. Progressive cavity pumps are the same because they have the U-joint and dead-end spots which are not always clean after CIP.

As there are no dead spots or hidden areas with hose pumps like Bredel CIP pumps, they are clean after CIP.

The second challenge is velocity. Every process or market requires a certain water velocity through the pump. In the food and beverage industry it is between 1.2 and 1.5 metres per second water velocity.

With a regular standard hose pump the hose is clean after CIP but we were never able to tick the box of velocity because the hose pump cannot run that fast due to its design. But with the Bredel CIP pump there is an open hose and the water coming from the CIP supply can run through the pipe system and through the pump with the required velocity.

With the Bredel CIP pump not only is it clean but it can also achieve the high flow because it doesn’t squeeze the hose anymore. This is a huge advantage of the Bredel CIP.

If it’s not a CIP pump design, another disadvantage is hose life. The hose life is reduced because of the temperature combined with the chemicals. The CIP temperature is always above 80 °C. Just the water at that temperature causes damage to the hose. The hose life reduces tremendously due to the high temperature in combination with the compressions and the chemicals. 

But with the Bredel CIP there aren’t any compressions, there isn’t force on the hose because the pump stands still and the water just runs through the pump. This increases the hose life compared to standard hose pumps and is a big advantage in CIP applications.

What are the key factors in selecting a CIP pump for a brewery and what should you consider for an upgrade?

What matters is whether you can get your required velocity and increased hose life. For example, if the CIP system provides 5,000 litres to the standard hose pump and the pump is running at its speed but can only handle 2,000 litres, there will be 3,000 litres of water left over. A bypass valve ensures the water that cannot go through the pump will go through the remaining system but it requires additional controls, valves and a small pipe system. 

But with the Bredel CIP pump the user can stop the pump, reverse it and with the open hose 5,000 litres can flow through the pump and a piping system is not needed. This saves an engineering company money and time and also extends hose life.

Are there any energy savings to be made with the Bredel CIP pump?

Bredel calculates that users of the Bredel CIP pump can achieve significant energy savings which leads to lower carbon emissions and a reduced environmental footprint. For example breweries using the Bredel CIP pump and operating 24/7 can save approximately four hours a day in cleaning as they can reverse the pump to retract the shoes and turn off the pump during cleaning. 

This saves a brewery four hours of power for a pump that runs during the CIP cycle and therefore reduces energy consumption by 16 % or 1,460 hours annually.

What applications can Bredel CIP pumps be used in?

This hygienic and efficient pump is suitable for food and beverage companies including a wide range of brewing applications as well as handling products like fruit puree. In the brewery industry Bredel pumps are commonly used for yeast dosing, harvesting and transfer, as well as for dosing flavourings, colourings, diatomaceous earth, PVPP (polyvinylpolypyrrolidone), silica gel and other additives. 

Beyond brewing the Bredel CIP pump is also widely used in dairies, cosmetics manufacturing and industrial applications such as paint production where frequent daily change-overs are required.

Why is the Bredel CIP pump such an important solution for applications where CIP processes are required?

Efficient processes depend on simple maintenance and high uptime which is what Bredel hose pumps bring to applications which require CIP processes. With the Bredel range the hose is the only wearing part and there are no moving parts in contact with the product, unlike with diaphragm, rotary lobe and progressive cavity pumps. 

This means Bredel provides a reliable low-maintenance operation with the pumped fluid contained in a long-life hose and now has a CIP feature.

Is the Bredel CIP retrofittable for existing users of Bredel hose pumps?

Yes. Existing users of Bredel can easily upgrade their pump rotor to the CIP variant in-situ with clear instructions without removing the pump from the process line and experiencing downtime.

By choosing the Bredel CIP pump you’re investing in a future-proof, hygienic solution built for the food and beverage, brewery, dairy and sanitary sectors. If you’d like to explore how this could be integrated into your plant, or talk through what matters most for your CIP system upgrade, I’m here to help.
