Além de serem equipamentos muito versáteis, as bombas pneumáticas de diafragma são conhecidas pela sua praticidade e confiabilidade. Podendo operar em ambientes adversos, essas bombas conseguem garantir segurança no transporte e bombeamento de inúmeros tipos de materiais.
For this reason, pneumatic diaphragm pumps have been increasingly used in the industrial environment. Many people still do not know that this equipment presents the possibility of pumping dangerous and abrasive fluids, liquids with the presence of solid particles and even be applied in the beverage and food industry.
However, it is important to remember that the type of pump to be used will depend on the fluid to be pumped. The pneumatic diaphragm pump can be made of plastic or metal and the choice will depend on the material to be transported, taking into account its characteristics and safety requirements.
How should this selection process be done?
Factors to consider before purchasing a pneumatic diaphragm pump
Among the solutions available on the market, pneumatic diaphragm pumps can deliver high performance without the need for complex operators and maintenance frequent. This is because this equipment was developed and built based on the needs of the industry, aiming at greater durability and efficiency.
In this way, industries that use pneumatic diaphragm pumps do not have to worry about establishing constant maintenance or with failures that can interrupt their operation. That said, here are the main factors to consider when deciding between a plastic or metal pump.
Application of a metal pump
Pneumatic diaphragm pumps made of metal such as cast iron, aluminum or stainless steel ensure superior performance in applications where higher pressures are required. These pumps are also ideal for industries that need to handle fluids with solids.
Another widely used application is in industries that pump fuel, abrasive or potentially dangerous products. As it is a device that can be grounded, pneumatic diaphragm pumps made of metal can provide the ideal solution for your industry.
Other advantages that this type of pump can guarantee for your business are:
- They are robust equipment;
- They are portable;
- Has a low initial acquisition cost;
- Can be used in explosive atmospheres;
- Can be used for hygienic applications;
- It can be transported and disassembled easily;
- And much more.
Due to its durability, this type of pump is ideal for the food industry and hygiene products. It is also widely used in oil and gas, chemical, slurry and solids handling applications.
Features of this pump make it a versatile and highly resistant solution. due to their constitution, these pumps can also be applied in environments where there is a great action of UV radiation, without material wear or problems with temperature.
Metal high pressure pumps
This type of pump has two air chambers to operate at high pressure. In order for it to be able to handle this additional pressure, they are made of metal, and can be applied in critical operations such as dewatering mines, feeding filter presses and transferring more viscous fluids with the presence of solids.
Application of a plastic pump
Plastic pumps are highly resistant to chemicals and deliver high flow rates without leaks. Contrary to what many think, plastic pumps can also be used to transport aggressive fluids, being highly resistant to corrosion.
One of the biggest advantages of this equipment is that due to the material of its constitution they are lighter and can be transported easily. Depending on the size of the operation and the needs of your industry, this pump can be found in smaller versions and has a low cost of ownership.
Plastic diaphragm pneumatic pumps can be made of PVDF, conductive polypropylene polypropylene.
The main applications of plastic pneumatic pump are:
- Chemical industry;
- Oil industry;
- Acid pumping;
- Caustic pumping;
- Waste water treatment;
- Paint and adhesive industry;
- And many others.
Although they can be used outdoors, pneumatic diaphragm pumps made of plastic are best used indoors. That's because your material can be damaged when the fluid freezes and can be damaged when there's a lot of UV exposure. This radiation can also damage the property of the fluid being conveyed, as this pump does not have UV capabilities.
The main advantages of this pump are:
- They are portable;
- They can be found in different sizes and materials;
- Has a light build;
- Its construction is screwed to avoid leaks;
- It has high chemical resistance;
- Portable;
- Submersible.
It is very important that before choosing a pneumatic diaphragm pump for your operation, consideration is given to the chemical compatibility of the materials. It is possible to find an ideal pneumatic pump for your application, as long as the factors presented above are taken into account.
