Peristaltic Liquid Pumps for Precision in Fluid Management

Peristaltic pumps excel in their gentle handling of shear-sensitive substances, ensuring contamination-free fluid transport, versatile flow regulation, and resilience to particle contamination. 

• Gentle Fluid Handling: Preserving substance integrity, essential for sterile medical processes. 

• Hygienic Transport: Eliminating contamination for critical procedures like dialysis. 

• Adaptable Flow Control: Offering precision in dosing, perfect for chemical additives. 

• Particle-Resistant: Ensuring fluid quality, even with particulate matter. 

• Robust Dry Running: Reliable operation across various conditions, including gas analysis. 

• High precision and accuracy: Required for several applications within medical devices and bioprocessing products

• Consistant Flow: Whether transferring various viscous liquids or even gases, peristaltic pumps maintain a consistent flow rate, making them an ideal solution for mixed-media transfer.

Peristaltic pumps have transcended traditional boundaries to become a cornerstone of precision fluid handling across a maturity of industries. Peristaltic pumps from Thomas serve an array of industries with their adaptability and hygienic advantages: 

• Medical and Laboratory: Safeguarding sterile fluid delivery, controlling dialysis flow, handling and enhancing equipment sanitation in medical settings. 

• Industrial: Efficiently managing condensate removal and precise dosing of cleaning agents. 

• Food and Agriculture: Ensuring precise dispensing of ingredients, chemicals, and aiding agricultural nutrient management. 

• Environmental and Analysis: Contributing to wastewater treatment efficiency and accurate gas analysis condensate removal in environmental monitoring. 

• Bioprocessing: Enable cross-contamination free supply of nutrients with high reliability and accuracy

Thomas peristaltic pumps are designed with key considerations to provide a comprehensive fluid management solution: 

• Pulsation Reduction: Spring-loaded mechanisms for smooth fluid delivery. This feature proves particularly crucial when handling delicate fluids like living cells.  

• Adaptable Pump Performance: Customizable for different tube sizes and flow requirements ensuring seamless performance across diverse applications.

• Adjustable Occlusion: Fine-tuning for various pressures and fluid characteristics to match varying pressure levels within fluidic systems. 

• User-Friendly Design: Easy maintenance is assured as the tubing or pump head can be replaced quickly and with ease. The design, without internal valves, enables bidirectional transfer capabilities ideal for liquid handling applications.

• Multi-Channel Efficiency: Simultaneous fluid transfer with a single motor driving a pump head featuring up to 15 separate tubes, diverse media can be simultaneously transferred or distributed across multiple vessels.  

• Roller Count Impact: Balancing flow rate and pulsation for optimal transfer. Pumps with two or three rollers can achieve higher flow rates but may experience more pulsation, while pumps with more rollers provide a smoother transfer with less pulsation. 

• Cross-Contamination Prevention: Peristaltic pumps excel in this regard, as only the tubes come into contact with the medium. Swift and simple tube replacement after each cycle ensures a clean and sterile process.  

In your pursuit of excellence, these factors guide your exploration of peristaltic pumps. Thomas' engineered solutions ensure a tailored solution that aligns perfectly with your specific operational needs.  

How Do I Choose Peristaltic Pump Tubing?  

Selecting the right tubing is essential for the best performance of your peristaltic pump. Thomas offers options to suit every need: 

• Silicone Tubing: Ideal for non-aggressive media. It remains elastic over a wide temperature range and is suitable for a range of fluids.  

• TPE Tubing: Durable and suitable for various applications. Combines the processability of Polypropylene with the elastomeric properties of EPDM. Common tubing materials include PharMed® BPT or Santoprene™.  

• Fluoroelastomeric Tubing: Resistant to chemical corrosion. Materials like Viton® are employed for these applications.  

Choose tubing based on lifetime, flow rate, accuracy, and fluid characteristics. Specialized materials like Versalloy™ are available to reduce spallation, ensuring fluid purity for sensitive applications.
