Difference: Peristaltic Hose Pump Vs Peristaltic Tube Pump

Peristaltic pumps are divided into peristaltic hose pumps and peristaltic tube pumps. Both are self-priming and positive pumps, and they are often known as peristaltic pumps. Both pumps rely on the same working principle. They operated by compression and releasing the flexible tube in a circular motion to push liquid through the tubing without exposing the liquid to mechanical parts.

In this blog, we will discuss the differences between the peristaltic hose pump and the peristaltic tube pump.

Peristaltic Hose Pump:

 - It uses a flexible hose (typically made of materials like rubber or synthetic materials) through which the fluid is pumped. The hose is clamped and compressed by "rollers" or "shoes" to create a flow.

- Generally designed to handle higher pressures and larger flow rates than tube pumps. Hose pump can commonly operate at pressures up to 16 bars. The flow rate is range 80-150 m3/h (660.4 GPM).

- Mianly transfer abrasive media. Used in effluent processing, mining waste, mud slurry transfer, chemical industrial and sand slurry transfer where higher pressures and flow rates are needed.

- The force needed to occlude the hose is much greater than for the tubing

- Bigger pumps and motors are required for a given flow rate with the hose pump.  

Peristaltic Tube Pump:

- Uses a thinner, flexible tube, usually made of softer materials like silicone or PVC. 

- Typically suited for lower-pressure applications. It can operate at pressures up to 4 bar. 

- They are suitable for microvolume liquid transfer. The microflow rate pump is usually about 0.1-380ml/min. The middle flow rate peristaltic tube pump is about 1-2L/min. Large flow rate peristaltic pump range from 6-33l/min.

- Commonly used in laboratory, chemical feeding, liquid dispensing machine supporting applications. The peristaltic tube pump solves the small volume and high precision liquid handling. 

- Typically have dry casing and use rollers with non-reinforced extruded tubing.

- Have a minimum of two rollers 180 degrees apart, and as many as 8 to 12 rollers.
