Peristaltic CIP Pump: Bredel's Ultimate Solution for Industrial Hygiene

Process hygiene is the cornerstone of production in the food, pharmaceutical and biotechnology industries. In this context, Clean In Place (CIP) is not just a procedure, but a regulatory and quality pillar. The heart of the efficiency and reliability of a CIP system lies in its pumping component.

While centrifugal pumps have traditionally been the «workhorses» for the delivery of large volumes of cleaning fluids, the role of the centrifugal pump has been to provide a more efficient and effective way of delivering cleaning fluids. peristaltic CIP pump has evolved dramatically. Thanks to technological innovation, in particular that introduced by Bredel, These pumps have become the superior solution for pumping products and, critically, for optimising the cleaning process itself. The technology of the peristaltic pump has proved invaluable, and now, the Bredel peristaltic pump is synonymous with excellence.

This technical paper explores the need for cleaning on site, The challenges faced by traditional pumping systems, and how the technology of Bredel has redefined efficiency, hygiene and component life in the most demanding applications by providing true CIP-capable pumps.

Understanding the Clean In Place (CIP) Concept

IPC refers to the method of cleaning on site of containers, equipment and piping that come into contact with the product being pumped, without the need to disassemble any of the parts. This process, essential for food safety and pharmaceutical quality, is automated and generally involves a rigorous sequence of steps including pre-rinse, detergent application and final rinse, often at high temperatures (up to 85°C).

The cycles of CIP cleaning are extremely demanding on equipment. The cleaning agents, which include acids and caustics, require that the pump materials and pipes are chemically compatible and that the design avoids dead zones where micro-organisms can proliferate.

The Evolution of CIP Capable Pumps

Previously, the industry's focus was on pumps that could simply withstand cleaning cycles. However, the evolution of hygiene standards has led to the need to CIP-capable pumps that not only resist, but also actively facilitate the cleaning processes.

• Process Pumps: Most companies are looking for a process pump that can perform standard transfer tasks and, at the same time, be integrated into the cleaning cycle.
• CIP Capable Pumps: These pumps must comply with standards such as EHEDG and FDA certification, ensuring maximum sanitation.
• Roles in the CIP: While centrifugal pumps are used as delivery pumps, the peristaltic pump has excelled in the precise dosing of reagents.

State-of-the-art CIP-capable pumps enable a holistic approach, minimising equipment redundancy and cleaning time. The need for frequent cleaning in critical sectors such as the food and pharmaceutical industries makes the choice of a true peristaltic CIP pump a critical investment decision.

Challenges Overcome by Peristaltic Pumps

The challenges of pumping in the food industry, the pharmaceutical industry and the chemical industry are multiple, including:

1. Handling of Non-Newtonian Fluids: The peristaltic pump handles highly viscous or shear-sensitive fluids without problems.
2. Particle Handling: The peristaltic pump (or hose pump) is ideal for pumping liquids with suspended solids, a challenge that can quickly damage the seals and stators of progressing cavity pumps.
3. Critical Dosage: Accurate dosing of additives or disinfectants is critical to product quality and CIP efficiency.

A key example is the dosing of disinfecting agents. Older pumping systems experienced «vapour locking» and inconsistency, which compromised the CIP cleaning end. The positive displacement nature of the peristaltic pump guarantees a precise dosing and uninterrupted. Today, the market demands only CIP-capable pumps that eliminate these risks.

Peristaltic Pump Bredel IPC

The technology of the Bredel CIP peristaltic pump addresses and solves these challenges in a fundamental way. Its seal- and valve-free design eliminates contamination dead zones. However, the Bredel CIP peristaltic pump goes further, focusing on the Efficient cleaning and the durability of the components.

The Key Innovation: Automatic Retractable Shoes

The turning point of the Bredel CIP Peristaltic Pump is its innovative design with automatic retractable shoes. This feature is specifically designed for CIP processes and is the key differentiator that defines these state-of-the-art CIP capable pumps.

Hygiene and Accelerated Flow for Cleaning Processes

During the CIP cycle:

• Automated retraction: Reversing the direction of rotation retracts the brake shoes, a unique feature of the brake shoes. CIP-capable pumps.
• Free and Turbulent Flow: The hose is completely released, allowing the cleaning fluid to circulate at the same rate as the cleaning fluid. high turbulent speeds (exceeding 2 m/s), which is crucial for a Efficient cleaning of the pipeline.
• Validation of Cleanliness: The CIP-capable pumps Bredel's methods facilitate compliance with the Sinner Circle and validation of the cleaning processes to the highest standards.

Dramatic Life Extension and Operational Savings

Exposure to 85°C and corrosive chemicals under compression is the main enemy of hoses.

• Wear Reduction: When using CIP-capable pumps with retracted shoes, hose compression during CIP is eliminated, preserving hose material and extending hose life.
• Energy Saving: The peristaltic pump can be switched off while the cleaning flow is being driven by a centrifugal pump in the system, resulting in lower energy consumption and cleaning time reduced.

The Bredel range offers models such as the Bredel CIP 40 pumps, The new CIP system combines a high flow rate for product transfer with this advanced CIP functionality. This type of CIP-capable pumps are the pinnacle of hygienic engineering.

Dosing and Process Applications

The positive displacement nature of the Bredel ensures an exceptional dosing accuracy for critical tasks:

• Dosing of Chemicals: Ideal for the addition of flocculants or fining agents.
• Filtration in the beverage industry: Bredel pumps are used in the beverage industry filtration, The CIP phase is carried out by dosing diatomaceous earth and additives before the CIP phase.

Technical Specifications (Bredel CIP 20-32)

For the Food industry, having CIP capable pumps of this calibre means safer operation and drastically reduced maintenance costs. Bredel's peristaltic pump technology, with its seal-less design and retractable shoes, positions it as the leading peristaltic CIP pump.

Conclusion

The Bredel Peristaltic CIP Pump represents a significant advance in hygienic process engineering. By fusing the inherent purity and gentle handling of peristaltic pump technology with the innovation of automatic retractable shoes, Bredel has solved the compromise between the need for compression for pumping and the need for efficient cleaning without hindrance. Bredel's CIP capable pumps are no longer a simple component, but a process optimisation tool.

For companies looking for maximum hygiene and reduced operating costs through frequent cleaning and durability, investing in a Bredel peristaltic CIP pump is the right technical and economical decision.
