The Daisy P is offers the best precision a peristaltic pump can offer. The pump head is relatively light yet very stiff, and is equipped with 6 stainless steel rollers. Together, these features ensure smoother and more accurate pumping — even in higher back pressure conditions.
The specialized mounts used in this pump are designed to pre-stretch the tubing and to guide it within narrow grooves, preventing the tubing from slipping or shifting. This, in turn, results in highly reproducible pumping performance during the entire lifetime of the tubing.
The mounts work with special tubing with end-stops, which prevent the tubing from sliding during operation, further enhancing the precision and accuracy of the pump.
New tubing installation is straightforward. Simply remove the tubing cartridge by pressing the elastic lock arm on the side (1) and attach new tubing as shown in (2) by stretching two adjacent tube stoppers between the arms of the cartridge. Various tubing models may come with three tube stoppers that offer two pump attachment regions — when one section wears out, the user may switch to the other section and reuse the same tubing. Once the tubing is installed on the cartridge, press the cartridge onto the pump head as shown in (3). The tubing should stretch and wrap over the top half of the roller-rotor assembly as the cartridge is inserted. Afterwards, the top lever on the cartridge should be rotated counterclockwise (4) to apply pressure on the tubing. The knob on the lever may be tightened to adjust the pressure on the tubing, depending on the outer diameter of the tubing.
The nominal flow rates that can be achieved on the Daisy Peri P pump with the various tubing sizes offered by Scalables (either silicone or PharMed BPT) are as follows:
Every time a new tubing is installed and the cartridge pressure on that tubing might have changed, it is a good idea to recalibrate the flow rate in the context of the application. For instance, if the pump is connected to a number of other tubings, plumbing, channels and devices, run and calibrate the pump’s output flow with everything connected. In this manner, you can achieve the highest reproducibility and precision. To maintain high flow precision, it may also be necessary to tighten the pressure knob on a given cartridge as the tube accumulates usage time and gradually gets stretched out.

Peristaltic Pump Tubing: Essential Selection and Maintenance Tips
Peristaltic pumps offer versatile fluid transfer solutions, but their efficiency and longevity heavily rely on proper tubing selection and maintenance. Let’s delve into key considerations and actionable tips to ensure optimal performance and durability of peristaltic pump tubing.
Understanding Wear and Tear
Over time, peristaltic pump tubing can degrade, primarily due to damage from the pump head’s rotor. This damage often stems from incorrect tubing length, causing repetitive friction with the rotor edge during operation. This friction accelerates wear and tear, leading to potential bursting after extended use. Prompt replacement and preventive measures are crucial to mitigate such issues.
Selecting the Right Tubing Material
Choosing the correct tubing material is paramount. Conduct a chemical compatibility test to ensure it withstands the pumped substance and operating conditions. Temperature, system pressure, and bore size are critical factors influencing tubing selection. Optimal dimensions and material quality enhance tubing lifespan and prevent premature failures.
Installation and Maintenance Best Practices
Proper installation is fundamental. Ensure tubing is straightened and securely clamped to prevent displacement. Regular inspection for wear signs like thinning or abrasions is recommended. Prompt replacement upon damage minimizes downtime and maintains fluid transfer efficiency.
Essential Maintenance Tips
Regularly monitor tubing life expectancy, considering factors like transparency, gas permeability, and regulatory compliance. Additionally, recalibrate systems as needed to address flow rate drop-off over time. Conduct extractable and leachable studies for applications requiring stringent quality control.
If pump tubing breaks, creating a leak over the peristaltic pump, promptly wipe the pump head and body dry. Depending on the type of fluid leaked, spraying and wiping with 70% isopropyl alcohol might be needed. Make sure the pump head and rollers are clean, free of any residue or particulates before installing a new tubing.
Good quality pharma BPT tubing can last up to 1000 hours of operation with water. If there is considerable back pressure, increased temperature or chemical interactions between the fluid and the tubing material, this lifetime will be reduced. Silicone tubing can last up to 200 or more hours of operation.
Connecting Peristaltic Pump Tubing
Pay attention to suction and delivery pipe bores, ensuring compatibility with tubing size. Use larger bore tubing for viscous fluids and maintain flexible tubing lengths to minimize impulse losses. Optimize pump speed based on application requirements to maximize tube life, flow rate, or accuracy.
Investing in Quality
Choosing high-quality tubing from reputable suppliers minimizes risks of failure and ensures consistent performance. While cost-effectiveness is essential, prioritize durability and compatibility with application requirements to optimize long-term reliability. We provide only the highest quality tubing selections on our site.
Conclusion
Peristaltic pump tubing plays a crucial role in fluid transfer operations, and proper selection and maintenance are vital for sustained performance. By adhering to best practices, monitoring wear, and investing in quality materials, users can enhance pump efficiency, minimize downtime, and prolong tubing lifespan, ensuring reliable operations across diverse applications.
