The Loctite PU20 Digital Peristaltic Dispenser is a precision fluid dispensing system designed for accurate, repeatable, and reliable adhesive application. This innovative device represents the next generation of dispensing technology, ideal for both industrial and laboratory environments. With digital control and advanced peristaltic pump mechanics, the Loctite PU20 ensures consistent flow of adhesives, sealants, and other low- to medium-viscosity materials without contamination or waste. Its ease of use, coupled with Loctite’s reputation for quality, makes it a top choice for manufacturers seeking efficiency and precision in adhesive processes.
Overview of the Loctite PU20 Digital Peristaltic Dispenser
The Loctite PU20 Digital Peristaltic Dispenser is designed to deliver controlled amounts of liquid adhesives using a non-contact, peristaltic pumping mechanism. This means that the material only comes into contact with the tubing, not the internal components of the dispenser. As a result, contamination risks are minimized, making it perfect for cleanroom applications and sensitive production environments.
One of the standout features of the PU20 is its digital interface, which allows users to easily program and adjust flow rates, dispensing times, and interval settings. Whether it’s for applying Loctite adhesives in small electronic assemblies, sealing components in medical devices, or managing fluid transfer in precision manufacturing, the PU20 provides unmatched versatility and control.

These specifications make the PU20 suitable for a range of industries that require clean and accurate dispensing, including electronics, automotive, aerospace, and medical device manufacturing. Its precision and reliability help reduce material waste while increasing production efficiency.
How the Peristaltic System Works
A peristaltic dispenser operates by compressing and releasing flexible tubing using a set of rotating rollers. As the rollers move along the tubing, they create a gentle squeezing motion that pushes the fluid forward in a smooth and controlled flow. Because the liquid never touches any part of the dispenser other than the tubing, the system remains clean and easy to maintain.
In the Loctite PU20, this principle is enhanced by digital control and microprocessor-based regulation, ensuring that the amount of adhesive dispensed is consistent each time. The peristaltic motion also allows for precise dosing, even in delicate or micro-sized applications. This makes it particularly useful for adhesive tasks where precision and repeatability are critical.
Advantages of Using a Peristaltic Dispenser
- No risk of cross-contamination between materials
- Quick and easy tube changes for different adhesive types
- Minimal maintenance since no valves or seals are in contact with the fluid
- Accurate flow control suitable for small and large dispensing jobs
- Reduced waste compared to manual application methods
These advantages are especially beneficial in clean manufacturing environments, such as those producing electronic components or medical devices, where even minor contamination can affect product quality.
Applications of the Loctite PU20
The versatility of the Loctite PU20 Digital Peristaltic Dispenser allows it to be used across many industries. Its ability to deliver consistent, repeatable amounts of fluid makes it suitable for any process where precision is essential.
Common Applications Include
- Electronics ManufacturingApplying controlled amounts of solder mask, conformal coating, or adhesive for PCB assembly.
- Medical DevicesDispensing bio-compatible adhesives and lubricants for catheters, syringes, and diagnostic devices.
- Automotive ComponentsApplying sealants and bonding agents for sensors, switches, and lighting assemblies.
- Laboratory UseControlled fluid transfer in research and testing applications.
- Packaging IndustryApplying uniform layers of adhesive for sealing and labeling applications.
Each of these applications benefits from the PU20’s ability to maintain uniform dispensing performance, which ensures product consistency and reduces rework or defects.
Ease of Operation and User Interface
The Loctite PU20 Digital Peristaltic Dispenser is designed with user-friendliness in mind. Its intuitive digital interface allows operators to set dispensing parameters with minimal training. The display screen provides real-time feedback on the dispensing rate, time settings, and operational mode.
Operators can choose between manual dispensing (controlled via a footswitch), timed dispensing (for consistent deposits), or interval dispensing (for automated repeated cycles). This flexibility ensures that the dispenser can adapt to different production requirements, whether for single applications or high-volume, automated processes.
Changing tubing or materials is also quick and hassle-free. Since the adhesive only flows through the tubing, switching between different Loctite products simply involves replacing the tubing, without any risk of contamination or clogging.
Maintenance and Durability
One of the most appealing aspects of the Loctite PU20 is its low maintenance requirement. Because there are no valves, seals, or plungers in contact with the adhesive, the internal components of the dispenser experience minimal wear. Regular maintenance is limited to replacing tubing when it shows signs of wear, making the device cost-effective over time.
The dispenser’s durable construction also ensures a long operational life, even in demanding production environments. Loctite’s engineering standards ensure that the PU20 can withstand continuous operation while maintaining consistent performance.
Maintenance Tips
- Inspect tubing regularly for signs of wear or degradation.
- Keep the exterior of the unit clean and free of adhesive residue.
- Store the dispenser in a dry, temperature-controlled environment.
- Calibrate flow rate periodically to maintain optimal performance.
