The Structure Of Peristaltic Pump Head

  • by

Peristaltic pump is composed of driver, pump head and tube. The driver is the power, the pump head is the part that carries the driver and the tube, and the liquid is transmitted in the tube.

What is the working principle of peristaltic pump?

Peristaltic pump is a “pillow” shaped fluid formed by a pump tube between two rotating rollers.The volume of the “pillow” depends on the inside diameter of the pump and the geometry of the rotor. The flow rate depends on the product of the speed of the pump head and the size of the “pillows” and the number of “pillows” produced by the rotor per revolution. Just like the picture below:

What is the structure of peristaltic pump head?

The pump head consists of three parts: pressure block, roller and tube clamp

1.Pressure block:elastic model, adjustable model and fixed model.

Elastic model: the pressing block moves elastically according to the operation

Adjustable model: mechanically adjust the pressure of the pipe to control the flow

Fixed model: fix the tube by tube sleeve, tube clamp, tube joint, etc

2.Roller: bearing, pure friction, mechanical spring, tube clamping and fixing

Bearing: reduce friction and prolong the service life of hose. It is suitable for thick transmission pipe, high transmission pressure and high speed transmission

Pure friction: high friction, suitable for pipe washing and low speed transmission

Mechanical spring: the distance between roller and pressing block can be adjusted to adapt to different thickness of tube.

3.Tube clamping and fixing: fix the tube by tube sleeve, tube clamp, tube joint, etc。


Peristaltic pump application field:chemical Industry,mining industry,metallurgical industry,manufacturing paper industry, paint and coating industry, food Industry, ceramic industry, oil industry, water treatment industry, medical machinery industry, pharmaceutical industry applications and so on.

According to the function of the peristaltic pump, Lead Fluid peristaltic pump is divided into speed variable peristaltic pump, intelligent flow peristaltic pump, intelligent dispensing peristaltic pump and so on. We will choose the suitable peristaltic pump for you according to your requirements for liquid transmission and working environment.
