Peristaltic pumps have many applications within the chemical industry. These positive displacement volumetric pumps can work with all types of fluids, although each industry has specific needs from the point of view of flow and working pressure. These two basic concepts of fluid mechanics will be decisive to choose the most suitable type of pump for each activity and achieve optimum performance. Next, we review the most used peristaltic pumps in the chemical industry depending on the working pressure that we need to reach.
Peristaltic pumps for small flow and low pressure
This type of industrial peristaltic pumps is used for the dosing and transfer of all types of fluids in small flows and low pressure. By modifying the internal diameter of its tubular element we can adapt the pump to the necessary flow. For flow rates of up to 0.16 ml/rev, we find diameters below the millimeter, while above 10 ml/rev we need tubes with a diameter around 8 mm. Peristaltic pumps usually work with liquids, but they are also capable of pumping fluids with particles in suspension or containing gases or vapors.
The chemical industry is one of the sectors with greater applications for these industrial peristaltic pumps, used to dose all types of fluids, such as dyes, pigments, resins, latex, acids, oils, inks or glues. In addition, this type of peristaltic pump for small flow is also used for the dosing of additives in the food industry or the sampling and dosing of chemical products for water treatment.
Peristaltic pumps for working pressures of up to 8 bar
The industrial peristaltic pumps indicated for working pressures up to 8 bar work with flow rates from 10 to 1,200 l / h. Depending on our needs, there are different types of connections and drive systems, at fixed or variable speed. The tubular part of the pump has a system of tightening by rollers. In addition, for these working pressures, it is recommended that the peristaltic pump have a reinforced hose and an additional lubrication system to facilitate the transfer of fluids in a gentle and delicate manner.
If we need to increase the flow, in the current market you can also find peristaltic pumps in the Boyser company, for working pressures of up to 8 bar capable of working with flow rates from 100 to 44,000l / h. Like the previous ones, this type of pumps usually has a system of tube tightening by rollers and reinforced hose.
In the chemical industry, these peristaltic pumps are suitable for working with inks, glues, dyes, acids, peroxides and other abrasive substances. They are also very common in the cosmetic industry or drugstore. If you have doubts about the most suitable type of pump for your activity, consult with your industrial pump manufacturer to find a solution adapted to your needs.
Peristaltic pumps for working pressures up to 15 bar
Peristaltic pumps designed for this pressure work with flow rates from 100 to 36,000 l / h. The chemical industry is a good example of the versatility of this industrial equipment, widely used to work with corrosive acids, paints, glues or detergents.
This type of industrial pumps, of the company Boyser, have a system of tightening of the tube by footings and internal lubrication in the body of the pump. The suction capacity of the peristaltic pump can be improved by the installation of vacuum equipment, indicated for high viscosity products.
