Peristaltic pump is widely used in the field, for example, the development of the laboratory: peristaltic pump in the small volume of fluid distribution and measurement with good reproducibility, very little delivery of common clogging and siphon phenomenon. The combined pump system can be used for the same pump. Common use occasions include: transportation, tissue specimens and liquid decolorization, perfusion chromatography; pharmaceutical drug production: because the "GMP" requirement, the peristaltic pump is extremely popular in the pharmaceutical factory, such as biological agent filling; food chemical process: smooth conveying viscous fluid and the thin and soft particles. Fast and self cleaning capability is popular. Common uses are: transportation of fruit juice, yogurt, flavoring agent, syrup food production line or single equipment; general field: peristaltic pump can be continuous pumping in the river, and can solve many difficult problems of pump. It can transport waste water, suspended solids, corrosive chemicals and other difficult fluids. Special solutions can be added to the harsh factory environment. Common uses include: fuel liquid, printing ink, laundry chemical solution, grinding fluid, lubricating fluid, such as pumping. Peristaltic pump in the use of the process will also deliver strong corrosive medium, this situation for peristaltic pump what kind of impact?

Peristaltic pump is subject to mechanical wear and corrosive medium erosion two kinds of damage. In the application of the pump in the production process, there are many transport environment and transport of the media with strong corrosion, corrosive materials have special requirements for the pump. When the conveying medium in solution by direct contact with the medium material, and the pump during operation in addition to the corrosion test by corrosive medium, but also by the mechanical wear of pump operation. In the case of these two kinds of wear and tear, the life of the peristaltic pump will be reduced and the failure rate will be increased significantly.

Corrosive medium is often accompanied by high temperature, high pressure or impurities, which will further affect the life of the pump. A variety of chemical substances and organic solvents in the transfer process is often accompanied by an increase in temperature, and many of the media will also be due to a variety of reasons for the existence of high viscosity and large proportion of the phenomenon. Peristaltic pump in the use of the existence of high speed and high shear speed will accelerate the loss of the pump.

Compared with other pumps, peristaltic pump nursing cost is low, other pumps for maintenance and repair time of transmission medium takes five or six hours, and only need to replace the peristaltic pump pump can finish the maintenance work. It is also necessary to move, transfer, and re install it in the maintenance process. It has a great influence on our work efficiency. So you can think of, how much is the convenient replacement of the pump. And we can transfer liquid, choose different price pump. Peristaltic pump body maintenance cycle is very long, if the use of the situation is better, only half a year to carry out a maintenance on it.
