5 essential factors to consider when choosing one bomba diaphragm pneumatics
The pneumatic diaphragm pump is used to transport various types of fluid in chemical, food, pharmaceutical, among other industries.. Although it is a very versatile piece of equipment, the selection process must take into account some very relevant factors, which must be considered according to the needs of the industry:
- Fluid type;
- Fluid viscosity;
- Flow quotient;
- Pressure;
See below how each of these factors can influence the choice of the best pneumatic diaphragm pump:
Type of fluid
This is the first aspect that must be considered in the choice 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 it is essential to consult a table chemical compatibility 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.
Fluid viscosity
Just like the chemical composition, the Viscosity is a determining factor in the process of choosing a pump diaphragm pneumatics. This type of equipment transports and manipulates fluids delicately, without damaging its structure. Therefore, viscosity is directly related to the size of the pump that will be applied.
To do this, you can consult the viscosity correction curve to determine which model is best for your needs. This way, the fluid will be transported through a tube with the ideal size to maintain its structure and not harm its quality.
Flow Rate
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 flow can be easily controlled with the help of a regulator in the pump's air inlet, which is not always possible with other types of pump.
compressed air pressure
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 during the discharge.
Temperature
Some fluids can be handled at high temperatures, and this must be considered, as well as chemical compatibility. THE temperature variation is related to the useful life of the pump, and it is very important to consider this aspect. The elastomers present in diaphragms, seals and valve balls are components that help the pump deal with these variations.
Due to the different materials used to make the pumps, don't forget to evaluate thermal compatibility when choosing the best product for your needs.
