Being one reliable supplier of chemical feed systems, Cannon Water Technology provides peristaltic pumps and their required accessories. All pumps listed below are sourced from top industry-leading brands.
Working Principle of Peristaltic Pumps
The peristaltic pump works on the principle of peristalsis, alternating compression and decompression of the hose or tube, drawing content in while propelling product away from the pump. The rotor of the pump compresses and decompresses the tube at specific intervals. This creates a series of waves that move along with the tube length. As the tube is compressed, the inside fluid moves forward, creating a positive displacement action, and a precise volume of fluid is moved with each compression.
One significant advantage of these pumps is that fluid is only pumped when it comes in contact with the interior surface of the tube. This makes them appropriate for pumping corrosive, viscous, or sensitive fluids without contaminating the pump.
Beneficial Features of Peristaltic Metering Pumps Offered by Cannon Water Technology
Our peristaltic pumps have been used across industries owing to the beneficial features they offer. Here are some important ones.
- Our high flow peristaltic pumps move fluids using a squeezing motion rather than direct contact with mechanical parts. Therefore, they can handle delicate or sensitive substances without causing damage.
- Being positive displacement pumps, they provide precise and repeatable fluid metering and dispensing, guaranteeing precise control over flow rates and volumes.
- At Cannon Water Technology, we offer analog and digital peristaltic pumps with varied specifications. Both feature a new PC front cover that opens easily and stops in an open position, allowing tool-free tube replacement.
- Analog pumps use potentiometers to control the analogic speed. They feature edge-free squeeze, making tube replacement easier. Most of our pumps come with a complete installation kit, including a PVC transport tube and a foot filter with ceramic weight.
- Our digital peristaltic pumps have an easy-to-program digital menu that facilitates precise and accurate settings. Features such as numeric variable speed control, rinse limit, rinse delay, and alarm delay help enhance operational control and flexibility.
- Most digital pumps have an IP65 protection degree and class II electrical insulation, ensuring reliable performance even in challenging environments. The password protection feature adds an extra layer of security to these pumps, preventing unauthorized access to settings and configurations.
- Our quality and performance-driven high pressure peristaltic pumps can handle varied pressures. Thus, they work best with flow rates in low micro-dosing applications and high outputs for chemical transfer applications.
- The on/off/priming switch activates and deactivates peristaltic pumps. However, some are self-priming, which means they can start pumping fluids without the risk of air locking.
- All pumps are ideal for handling various fluids, including chemicals, viscous liquids, slurries, and even gases. This makes them suitable for use in industries such as food and beverage, pharmaceuticals, water treatments, and laboratories.

Benefits of Choosing Peristaltic Dosing Pumps
Peristaltic pumps have a drive system that turns rollers, which compress the tube, creating a vacuum which helps fluid flow through the tube. The pump has only one wetted part – flexible tubing. These additional benefits have contributed to their growing popularity:
- The pump has a unique design which makes them self-priming, and enables them to handle high viscosity fluids.
- Fluid only comes in contact with the flexible tubing. This helps create an easy-to-clean, contamination-free system.
- The flexible tubing is easily replaced which helps to minimize maintenance.
- Unlike other pumps, these pumps have a low shear and gentle pumping action, which makes them ideal for handling various sensitive fluids.
How to Select Appropriate Peristaltic Pumps for Your Industrial Applications?
Selecting high pressure peristaltic pumps seems straightforward; however, you need to consider several factors with and attention to detail. These factors help in ensuring the optimal performance and efficiency of these pumps. Here are some pointers for choosing the right peristaltic pumps.
- Fluid Compatibility:It is important to check the fluid's compatibility with the material being used in the pump's construction. Also, ensure that the pump is compatible with the fluid's viscosity, temperature, pH, and abrasiveness.
- Pumping Accuracy:Determine the precision and accuracy level required for fluid metering or dispensing applications. Select the pump with the appropriate accuracy level to meet the specific requirements.
- Flow Rate and Pressure Ratings:This is another critical parameter to consider when selecting high flow peristaltic pumps. These pumps must withstand the system's operating conditions without compromising quality. Therefore, identify the flow rate and pressure ranges required for your application and choose the ones that meet these specifications.
- Tubing Size and Material: The selection of the tubing size and material depends on factors such as the desired flow rate, pressure, and fluid compatibility. Different types of tubing materials offer different levels of flexibility, chemical resistance, durability, and more.
- Pump Configuration:Considering the space constraints and mobility of the application, determine whether you require a benchtop, portable, or handheld pump. Also, the speed constraint must be checked to get precise control over flow rates. Depending on the application requirements, you can choose either a fixed-speed or variable-speed pump.
- Control and Monitoring:Evaluate the pumps' control for ease of operation and monitoring. Some considerations are manual or digital speed adjustment, remote control capabilities, and monitoring functions.
- Maintenance and Serviceability:Consider the pumps' maintenance and overall lifespan. Select pumps that allow easy cleaning, testing, inspection, and component replacement if required.
- Budget: Although it is not a whole-determining aspect, it is essential to consider the budget while selecting the pumps. This can vary depending on factors such as features, brand, construction quality, and pricing. Select the pump that offers the best returns on investment while meeting the performance requirements.
