What Knowledge Do We Need to Know Before Purchasing a Miniature Peristaltic Pump?

Micro peristaltic pump is commonly used in the production processes of chemical and pharmaceutical enterprises. These enterprises share a common characteristic that they use some chemical raw materials during production, which may cause certain degrees of pollution and corrosion to surrounding objects or facilities. As the micro peristaltic pump can isolate the fluid in the pump tube, it can quickly replace the pump tube during use and allow the fluid to flow back, making it widely used in various industries such as chemical, metallurgy, and papermaking.

Introduction micro peristaltic pump

Micro peristaltic pump is an important component for conveying fluids in instruments and meters. Different from large industrial pumps, instruments and meters have some special requirements for pumps: generally, the flow rate and lift are small, they have self-priming ability, require no maintenance and lubrication, and do not contaminate the sample when isolated from the sample, have no leakage, are small in size, light in weight, and impose strict noise restrictions in many occasions. They also have good electromagnetic compatibility, some need to meet unmanned, long-distance transmission of data, control, allow dry operation, etc. Therefore, what do we need to know before purchasing the Micro peristaltic pump?

Selection micro peristaltic pump

Choose the pump head 

When purchasing micro peristaltic pumps, enterprises should choose the peristaltic pump head carefully. If the flow rate of the selected pump head is not suitable, the desired effect cannot be achieved. The pump head of the selected micro peristaltic pump should be able to meet the requirements of quickly replacing the hose. When there are multi-channel requirements, enterprises should choose to purchase multi-channel pump heads or connect the pump heads in series. In addition, when choosing the pump head, the impact of fluid overflow on the material of the pump head should also be considered.

Choose the hose

The hose is a component of the micro peristaltic pump. If the quality and performance of the hose used are not good enough, it will have adverse effects on the use. A good hose should have good chemical resistance, because most enterprises use materials with chemical components in the production process, and hoses with poor chemical resistance may be corroded or aged prematurely.

Choose the driver

For Micro peristaltic pumps, the higher the speed of the driver, the greater the flow. When purchasing micro peristaltic pumps, enterprises should choose the appropriate driver according to the required flow range. In addition, the control form of the driver should also be considered, including fixed or adjustable speed, flow correction, flow distribution, external control, and other forms.
