Peristaltic Pumps For The Chemical Industry

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 in choosing the most suitable type of pump for each activity and achieving optimum performance. Next, we review the most used peristaltic pumps in the chemical industry depending on the working pressure we need to reach.

Peristaltic pumps for small flow and low pressure

This type of industrial peristaltic pump 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. We find diameters below the millimeter for flow rates of up to 0.16 ml/rev. In comparison, above 10 ml/rev, we need tubes with a diameter of around 8 mm. Peristaltic pumps usually work with liquids. Still, they can also pump fluids with suspended particles 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 dosing additives in the food industry or sampling and dosing chemical products for water treatment.

Peristaltic pumps for working pressures of up to 8 bar

The industrial peristaltic pumps are 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 connections and drive systems at fixed or variable speeds. 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 gently and delicately transfer fluids.

If we need to increase the flow, in the current market, you can also find peristaltic pumps in the Boyer 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 pump 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 drugstores. 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 pump of the company Boyer has a system of tightening the tube by footings and internal lubrication in the pump’s body. Who can improve the suction capacity of the peristaltic pump by installing vacuum equipment indicated for high-viscosity products?
