Since the invention of the Archimedean screw in the 3rd century B.C., considered the first known pump, the advancement of technology has made possible the development of a wide range of pumps and fluid handling equipment for all types of applications. Pneumatic pumps, peristaltic pumps, twin screw and centrifugal pumps … Do you want to know more about how they work?
Keep reading and discover why pneumatic pumps have become one of the most widespread solutions in today’s industry.
- Double diaphragm pneumatic pump, also known by its acronym AODDP (from Air Operated Double Diaphragm Pump), is based on the technology invented and patented by Jom Wilden in California in 1955. The objective was to achieve a pump with sufficient resistance for the transfer of fluids within the mining and construction industry.
- Pneumatic pumps belong to the category of positive displacement pumps, like peristaltic pumps that you will find in Boyser. The principle of operation of this fluid handling equipment is based on hydrostatics, taking advantage of the pressure difference generated within the chamber by increasing and decreasing its volume by the action of the membranes or diaphragms to drive the fluid.
- The main characteristic that defines pneumatic pumps is their actuation by compressed air. There are also some models with electric drives, called electric pumps.
- The design of a double diaphragm pneumatic pump lacks packing and mechanical seals, so it is easy to operate and has minimal maintenance costs.
- A wide variety of materials can be used to manufacture the body of these industrial pumps, from plastics such as polypropylene to cast metals such as aluminium, iron or stainless steel.
- Pneumatic pumps technology stands out for its versatility. Most models are self-priming and can run dry, which is an interesting operational advantage. In addition, the current catalogue also includes submersible models or anti-corrosion versions.
- To adapt to the needs of each activity, there are different types of diaphragm. If you want to get the most out of these pumps and handling fluid equipment like the ones you will find in Boyser, be sure to choose properly the design and materials with which the membranes are made.
- Incorporating accessories such as pressure regulators for flow control or pulsation dampening lungs greatly improves pump performance, but will also help to minimize the risk of breakdowns and maintenance. In this way, in the long-term double diaphragm pneumatic pump represents one of the most profitable options on the market.
- Standard configuration pneumatic pumps, with spherical valves, are the most widely used model for industrial uses, ideal for the transfer of chemicals, cosmetics, paints, oils, acids and solvents, sludge and wastewater, vegetable oils, etc.
- For especially demanding applications, there are heavy-duty pneumatic pumps, with spherical or flap valves, or with pressure multipliers. The former is indicated for sectors such as mining, the chemical industry or sludge treatment. For their part, pneumatic pumps with pressure multipliers are suitable for discharge pressures of up to 17 bar.
As you can see, the double diaphragm pneumatic pump is one of the most versatile pumps and handling fluid equipment on the market today. If you want to know more about its advantages, ask your industrial pump manufacturer and find the perfect model to boost your business!
