Multichannel peristaltic pumps offer an economical, reliable, and contamination-free solution for fluid transfer, metering, and dispensing across a wide range of industries. From pharmaceuticals and biotech to food processing, agriculture, and water treatment, these systems have become a preferred choice for engineers seeking high-performance pumping with minimal maintenance and maximum flexibility.

How It Works

Peristaltic pumps operate by compressing flexible tubing in a peristaltic motion, pushing fluid through the tube without it ever contacting mechanical components. This ensures:

· Zero cross-contamination – the fluid only contacts the inner surface of the tubing.

· Only one wetted material – simplifying chemical compatibility concerns.

· Simplified cleaning and sterilisation – ideal for cleanroom and aseptic environments.

Key Advantages of Peristaltic Technology

· Self-priming and dry-run capable

· Reversible flow direction – simply by changing motor direction.

· Gentle pumping action – preserving fluid integrity, ideal for shear-sensitive media.

· Can handle solids – suitable for viscous or particulate-laden fluids.

· Compact and stackable pump heads – saving space and reducing cost (few mm per channel).

· Low-viscosity, water-like fluids flow easily through a wide range of tubing sizes. In contrast, higher-viscosity fluids often require tubing with a larger inner diameter and thicker wall, which results in slower flow rates. In such cases, increasing pump speed does not necessarily translate to increased flow.

· Our pump heads feature up to 10 rollers, delivering enhanced accuracy and significantly reduced pulsation—ideal for applications where precision and smooth flow matter most.

Why Multichannel?

Our multichannel peristaltic pump systems can accommodate up to 24 channels per drive, with custom options available for higher channel counts. All heads are driven by a single motor, reducing cost, footprint, and energy consumption compared to traditional multi-motor systems. The only limitation is motor torque and mechanical overhang, both of which we address with robust motor selection and support plate systems.

Accuracy and Flow Control

· Interchangeable tubing allows precise flow rate adjustment by changing the internal diameter (ID).

· Flow rate is directly proportional to motor speed and tubing ID.

· More rollers = greater accuracy and lower pulsation, but at reduced flow.

· Our DG pump heads feature up to 10 rollers for high-precision applications.

· Adjustable occlusion via ratchet and spring-loaded tracks protects tubing and ensures optimal performance.

Flow Rate & Channel Calibration

· Typical channel variation is ~10% (standard in multichannel design).

· For applications requiring individual channel calibration, we offer specialised 4-channel pumps with independent control.

· For varied flow rates per channel, either different tubing sizes or a custom solution is required.

Tubing Compatibility

Our pumps support a wide range of interchangeable tubing materials, including:

· Viton – excellent chemical resistance (up to 1 bar).

· Santoprene – durable and flexible (up to 1 bar).

· PVC and others – for high-pressure applications (> 1 bar).

Because the tubing is the only wetted part, our pumps are suitable for highly aggressive fluids, offering a simple, reliable, and clean solution.

Models and Options

· BT100 drive paired with DG pump heads is our most popular configuration.

· YZ pump heads are available for higher flow applications.

· DMG heads provide ultra-precise dual-channel solutions.

· Slide-on stoppers replace costly proprietary consumables in other systems, reducing waste and simplifying sourcing.

· Remote control options – All pumps can connect to PLCs, PCs, or other controllers for integration into automated systems.

Efficiency by Design

Compared to other pump technologies, peristaltic pumps are extremely compact. While most systems require large individual heads and motors, our stackable heads are just millimetres thick and can all be powered by a single drive. This not only saves space and cost, but also improves energy efficiency and system simplicity.

Conclusion

Multichannel peristaltic pumping systems provide unmatched versatility, cleanliness, and ease of use. Whether you require basic fluid transfer, precision dosing, or aggressive chemical handling, these pumps offer scalable solutions that reduce complexity and enhance reliability.

Our benchtop peristaltic pumps come with a 3-year warranty, ensuring long-term reliability and peace of mind.
