Peristaltic pump is the use of rotating roller extrusion hose used to transport fluid, in the transport of fluid, the fluid only flows in the hose, will not contact the pump body, will not produce cross infection, while conveying high precision, small shear effect. Because the peristaltic pump driver is a high-precision equipment integrating mechanical, electronic and software, it can receive a variety of external control signals to achieve external signal control, so it is often used as an ideal equipment for industrial supporting and distributed control. The following peristaltic pump manufacturers share the four major basis for peristaltic pump selection.

1. Determination of demand

Since the selection, it is necessary to first determine their own needs, mainly: flow size, accuracy requirements, transmission medium, number of channels, pressure range, suction division, control mode.

2. Selection of pump head

Number of channels: Determine the number of channels based on workload requirements.

Number of rollers: The number of rollers is a key factor in determining the size of the pulsation, and the number of rollers is determined by the level of the pulsation requirements.

Disassembly method: Simple, convenient disassembly method is a good choice.

3. Selection of hose

Inside diameter: The size of the inside diameter is proportional to the flow rate.

Wall thickness: The greater the pressure, the greater the wall thickness required.

Material: Special medium, special function hose should be selected, such as corrosion resistance, acid resistance, strong acid resistance, organic.......

4. Driver selection

Speed: Speed is proportional to the flow rate. Refer to the parameter diagram.

Accuracy: Select the corresponding drive with different accuracy.

Protection level: Different environments have different requirements for the protection level of the product, such as the working environment requires waterproof and dustproof, you should choose the driver that is suitable for the IP level.
