A peristaltic pump is a device which moves fluids through a flexible tube by using a rotating mechanism to create a series of squeezing and releasing actions.

This action propels the fluid along the tube without direct contact, making it suitable for delicate or sensitive materials.

Peristaltic pumps are commonly used in various industries for accurate fluid transfer and dispensing while minimizing contamination risks. You may check out our guides on what is a peristaltic pump and how does a peristaltic pump work.


So, let us tell you more about what a variable speed peristaltic pump is, it is a type of peristaltic pump that allows the user to adjust and control the speed at which the pump operates. Unlike fixed-speed peristaltic pumps, which run at a constant rate, a variable speed peristaltic pump offers the flexibility to change the pumping speed to meet specific flow rate requirements or process conditions.

In this regard, many users search for the best variable speed peristaltic pump for their use-type and so, we bring you the Spectra Scientific's Field Pro 3 Peristaltic Pump in which you can set speed according to your required rate.

Field Pro 3 offers a flow rate of 25-650 milliliter per minute, with smart electronics technology which allow speed to remain constant for 90% of pump life. It also comes with a battery life of up to 8 hours and the ability to act as a 12V pump controller. You can adjust the rate of the rotation or the size of the pump to control the speed of the pump.

Key features of a variable speed peristaltic pump include:

  1. Speed Control: Users can adjust the pump's rotational speed, which directly influences the rate at which the fluid is pumped through the flexible tubing. This allows for precise control over the flow rate of the pumped fluid.

  2. Flow Rate Flexibility: Variable speed pumps are versatile and can accommodate a wide range of flow rates, making them suitable for various applications that require different fluid transfer rates.

  3. Accurate Dispensing: The ability to finely tune the pump's speed enables accurate and consistent dispensing of fluids, which is crucial in laboratory, medical, and industrial processes.

  4. Process Optimization: Variable speed peristaltic pumps are ideal for applications where the flow rate needs to be adjusted based on changing process conditions, such as reactions that require specific mixing or reaction times.

  5. Reduced Shear Stress: These pumps are particularly useful for handling sensitive or fragile fluids because the user can minimize shear stress by adjusting the pump speed to provide a gentle and controlled flow.

  6. Automation Compatibility: Variable speed peristaltic pumps can often be integrated into automated systems, allowing for precise and programmable fluid delivery.

  7. Maintenance and Tube Life: Adjusting the pump speed can also impact the wear and tear on the tubing used in peristaltic pumps. Slower speeds might extend the life of the tubing and reduce the need for frequent replacements.

Variable speed peristaltic pumps find applications in a wide range of industries, including pharmaceuticals, biotechnology, food and beverage, water treatment, research laboratories and more.

They offer greater flexibility and control over fluid transfer processes compared to fixed-speed pumps, making them a valuable tool for achieving accurate and consistent results.
