Description
Technical Parameters
An 8 channel peristaltic pump, also known as an 8-channel peristaltc pump, is a special fluid transport device that periodically squeezes a hose to propel fluid forward and achieve liquid transport. Named after its working principle similar to human intestinal peristalsis, it is a positive displacement pump that uses hoses to transport fluids. This product refers to the pump having 8 independent peristaltc channels, which can simultaneously or separately deliver 8 different fluids. This type of pump has the characteristics of fluid isolation in the pump tube, quick replacement of the pump tube, retrograde flow of fluid, and dry operation, and therefore has a wide range of applications in multiple fields.
Specifications
Working principle
The working principle of the 8 channel peristaltic pump is based on the periodic compression and release of the hose.
The motor drives the roller to rotate:
The motor of the capital items drives the roller (or roller) to revolve around the motor axis, while the roller reduces friction with the surface of the capital items tube during its rotation.
The roller and capital items casing exert pressure on the capital items tube:
During the rotation of the roller, it exerts pressure on the capital items tube together with the pump casing, squeezing the air or liquid in the tube towards the direction of rolling of the roller.
Negative pressure is generated when the capital items tube recovers deformation:
Due to the elasticity of the pump tube, when the roller no longer compresses a certain area, the area will recover and deform, forming negative pressure, thereby attracting upstream liquid or gas into the area.
Continuous fluid transportation:
With the continuous rotation of the roller, the above process is repeated continuously to achieve continuous liquid or gas transportation.
Performance parameters
Its performance parameters mainly include flow rate, pulsation size, pressure, etc., which are affected by the following factors:
Pump tube inner diameter
The larger the capital items tube inner diameter, the greater the flow rate. Meanwhile, the inner diameter of the pump tube also affects the magnitude of pulsation, with smaller inner diameters resulting in smaller pulsations.
01
Motor speed
The faster the motor speed, the greater the flow rate. However, it should be noted that excessive rotational speed may lead to increased wear and tear on the pump tubing, affecting the service life of the pump.
02
Number of rollers
The more rollers there are, the smaller the pulsation. But too many rollers can also increase the complexity and cost of the pump.
03
Pump tube material
The choice of pump tube material directly affects the corrosion resistance and service life of the pump. Common pump tube materials include silicone, thermoplastic vulcanizate (TPV), PVC, etc.
04

Design Features
As an efficient fluid transfer device, the 8 channel peristaltic pump is unique in its ability to simultaneously handle multiple fluid media, with high flexibility, precision, and durability.
Its core advantage lies in its multi-channel design. This means that the pump can handle 8 different fluid media simultaneously without the need for additional diversion equipment or complex piping systems. This design not only improves transmission efficiency, but also reduces equipment footprint, making the overall system more compact and efficient.
In practical applications, multi-channel design has broad application prospects in various fields such as laboratories, pharmaceuticals, chemicals, and food processing. For example, in the pharmaceutical process, it may be necessary to transport multiple drugs or raw materials simultaneously; In chemical production, it may be necessary to simultaneously process multiple reactants or catalysts. The multi-channel design of the 8-channel capital items can easily meet these complex requirements, improving production efficiency and product quality.
The working principle of a capital items is to push the fluid forward by periodically squeezing the hose. This transmission method has unique advantages:
(1) Precise control: The transmission speed of the capital items can be precisely controlled by adjusting the motor speed, thereby achieving precise adjustment of the flow rate. In addition, since the fluid transmitted by the capital items is isolated in a hose, direct contact between the fluid and the pump body can be avoided, further improving the accuracy of transmission.
(2) Low shear force: The transmission method of capital itemss reduces the shear force experienced by fluids during transmission, which is particularly important for some fluids that are sensitive to shear forces, such as cell suspensions, protein solutions, etc.
(3) Self suction ability: Capital itemss have self-priming ability and can start and suck in liquid without liquid filling, which is very useful for situations that require self-priming function.
The hose materials used are diverse and can be selected according to different fluid media and working environments. Common hose materials include silicone, polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), etc. These materials have different characteristics such as corrosion resistance, high temperature resistance, and elasticity, which can adapt to different fluid media and working environments.
For example, silicone hoses have good biocompatibility and chemical stability, making them suitable for fields such as biomedicine and food processing; PVC hoses have low cost and good corrosion resistance, making them suitable for chemical and general industrial fields; PTFE hoses have extremely high corrosion resistance and high temperature resistance, making them suitable for harsh environments such as strong acids, strong alkalis, and high temperatures.
Another unique feature is its ease of maintenance and replacement. Due to the fluid transmitted by the capital items being isolated in the hose, when the hose is worn or damaged, it only needs to be replaced without disassembling and repairing the entire pump body. This greatly reduces the maintenance cost and downtime of the equipment.
In addition, the pump head and drive part of the capital items are relatively independent, making it easy to disassemble and clean. This is particularly important for situations that require frequent replacement of fluid media or cleaning and disinfection. For example, in the field of biomedicine, in order to ensure aseptic operations, it is necessary to regularly clean and disinfect equipment. The ease of maintenance and replacement makes this process simpler and more efficient.
Using high-quality materials and advanced manufacturing processes, it has a long service life and high reliability. The transmission method of capital itemss reduces friction and wear between the fluid and the pump body, thereby extending the service life of the equipment. At the same time, the capital items also has functions such as overload protection and fault alarm, which can promptly issue an alarm and stop running when the equipment fails, preventing further damage to the equipment.
In addition, it also has high accuracy and stability. Due to the precise control of the transmission speed of the capital items by adjusting the motor speed, the stability and accuracy of the flow rate can be ensured. This is particularly important for situations where precise control of fluid flow is required. For example, in the laboratory, precise control of the dosage and concentration of medication is required; In chemical production, precise control of the proportion and flow rate of reactants is required. High precision and stability can meet these complex requirements, improving the accuracy and reliability of experimental and production results.
