A peristaltic pump is a liquid delivery device that can control the flow rate. It is common to repeatedly compress the elastic tube to make the contents of the tube move in a certain direction, and the flow rate is determined by the diameter of the tube and the compression speed. Used in liquid chromatography and perfusion systems.
principle
A peristaltic pump is like squeezing a hose filled with fluid with your fingers, and moves forward as your fingers slide the fluid in the tube forward. The peristaltic pump is also based on this principle, but the finger is replaced by a roller. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump.
When the roller on the rotor presses through the pump tube, it throws the fluid out. When the pump tube behind the roller returns to its shape, a vacuum is generated and fluid is sucked in.

■Customer's selection plan: The combined design can get thousands of different configurations, fully considering the special needs of different users
■Provide a complete set of pump system size and flow amplification solutions from laboratory to production
■Comply with a series of laboratory and industrial specifications: UL, Cul, CE
■Sufficient inventory of pump heads, pump tubes, and drives ensure continuous operation of your pump system and reduce maintenance time.
Exploded diagram of the working principle of the peristaltic pump
The peristaltic pump system is suitable for laboratory, industrial manufacturing and field applications. It is a better choice for users and original equipment manufacturers (OEM).
Advantages of peristaltic pump
■No contamination-the liquid only touches the pump tube
■Durable-suitable for various industrial or laboratory conditions
■Easy to clean and clean-just simply replace the pump tube to work again
■Multi-purpose-soft, low-shear flow suitable for liquid, gas, two-phase flow and high-viscosity fluid
■Low maintenance-no seals, no valves
■Very good self-priming function-non-siphonic, can be dry-turned and self-priming
Complete system
Most CHENGHE peristaltic pump systems include three components: pump head, pump tube, and driver. To simplify ordering, we provide a series of factory-installed complete pump systems. To meet different needs, users only need one model to order The whole system, of course, you can also choose the pump head, pump tube and driver individually to match.
