Pneumatic pumps are positive displace minipumps belong g to the category of volumetric pumps, together with industrial pumps as widespread as peristaltic pumps. Their reliability, delicate product treatment and versatility have made the one of the most used models in such demanding sectors as the chemical, pharmaceutical, cosmetic or food industry.
If your business belongs to any of these sectors, pneumatic pumps represent an optimal solution to improve the performance of your facilities. Read on and discover how these industrial pumps work their characteristics and features.
Pneumatic double diaphragm pumps: how do they work?
Within the chemical industry, the most commonly used pneumatic pumps are double diaphragm or double diaphragm pumps found in Boyser. Its technology was invented and patented by Jim Wilden in 1955, and since then, it has become a piece of common equipment in any industrial activity.
The principle of operation of these pumps is very simple: the alternating movement of its double-diaphragm, pneumatically actuated, increases the pressure, increasing and decreasing the volume of the chamber to pump the fluid alternately.
Why choose a pneumatic pump?
- Versatility: pneumatic pumps are capable of working with all types of fluids, with different levels of viscosity and density, liquids with solid particles in suspension or even abrasive or corrosive fluids.
- The design of these industrial pumps makes them light and manageable equipment, without packing or mechanical seals.
- Adaptability: pneumatic pumps are capable of working with high and low-pressure and different flow rates.
- Resistance: the body of these pumps can be manufactured in different materials, to resist the most hostile environmental conditions and operate without a problem with toxic chemicals.
- Precision: pneumatic pumps are excellent as high-precision metering pumps, which makes them ideal for chemical processes.
- They are self-priming and depending on the model, they can operate dry.
- Low maintenance costs: unlike her rotary pumps, pneumatic die diaphragm pumps do not require any seals or mechanical seals, so they only require minimal maintenance and repair costs are very low.
Industrial pumps for the chemical industry
All the above qualities make a pneumatic double diaphragm pump piano an optimal solution for transferring all types of chemicals, inks, oils, paints, sludge and sludge, solvents or food products, such as wine vinegar or oil. As the liquid does not contact the pump body, it can also work with dangerous fluids, such as acid so corrosives.
If we talk about industrial pumps and fluid equipment in the chemical industry, lobe pumps that Boyser has also deserved special mention. In this model of rotary pumps, a fluid transfer is carried out thanks to the movement of two lobes, which rotate in the opposite direction. Forchemicalprocesses, the most commonly used are industrial lobe pumps, suitable for working pressures of up to 10 bar, reversible and self-priming.
In addition to the chemical industry, these industrial pumps also offer excellent results applied to the treatment of sludge, sludge, and sewage, oil or food products. Suppose our sector demands an aseptic treatment of the product.
In that case, industrial pump manufacturers recommend opting for sanitary lobe pumps capable of complying with the demanding quality standards of sectors such as the food industry, cosmetics, or pharmaceuticals.
