It is recommended that the two diaphragms be exchanged

A bomba pneumática de diafragma é utilizada para transportar diversos tipos de fluido em indústrias químicas, alimentícia, farmacêutica, entre outras. Embora seja um equipamento muito versátil, o processo de escolha deve levar em conta alguns fatores muito relevantes, que devem ser considerados de acordo com as necessidades da indústria:

  • Tipo de fluido;
  • Viscosidade do fluido;
  • Quociente de vazão;
  • Pressão;

Veja a seguir como cada um desses fatores pode influenciar na escolha da melhor bomba pneumática de diafragma:

See below how each of these factors can influence the choice of the best pneumatic diaphragm pump

This is the first aspect that must be considered in the selection process, especially in the case of flammable and corrosive materials. Contrary to popular belief, this decision goes far beyond opting for a plastic or metal pump, for this reason, it is essential to consult a essential to consult a chemical compatibility test before making your choice.

This table contains detailed information about the composition of the fluids and their respective chemical compatibility with the materials used in the manufacture of pneumatic diaphragm pumps.

In addition to aspects related to composition, it is also important to pay attention to some nuances related to safety when handling certain fluids.

For example: pumps that are used in the food or beverage industry must be specific for this type of fluid, and pumps that handle flammable fluids must be grounded.

Like the chemical composition, the essential to consult a diaphragm pneumatics. This type of equipment carries out the transport and manipulation of fluids in a delicate way, without harming its structure. In this way, the viscosity is directly related to the size of the pump that will be applied.

For this, you can consult the viscosity correction curve to determine which model is best for your needs. In this way, the fluid will be transported through a tube with the ideal size to maintain its structure and not impair its quality.

The efficiency of the pneumatic diaphragm pump is directly related to the flow factor X pump size. For this reason, sizing and flow rate must be considered when choosing the ideal pump for your needs. Remembering that the essential to consult a into the air inlet of the pump, which is not always possible with other pump types.

Because they have a one-to-one ratio, the pressure at which the pneumatic diaphragm pump is a determining factor in choosing this equipment. This means that the pressure that is applied is the maximum pressure to be reached in the discharge.

Some fluids can be handled at high temperatures, and this must be considered, as well as chemical compatibility. A essential to consult a, and it is very important to consider this aspect. The elastomers present in the diaphragms, seals and valve balls are components that help the pump deal with these variations.

Due to the different materials used in the manufacture of pumps, do not forget to evaluate thermal compatibility when choosing the best product for your demand.
