Once the chemical has been determined, it is identified in the AODD manufacturer’s Chemical Compatibility Guide. It is important to remember to use the guide from the AODD OEM brand from where you will be acquiring the pump. Although the guides may look similar and often cover the same range of chemicals, some OEMs offer different grades of metals or plastics. Some are proprietary to them and may not be equally compatible with the chemicals in the process.

Rapid industrialization is one of the other factors directly impacting the growth of the AODD pumps market. Population growth, coupled with urbanization, has directly led to an upsurge in the growth of industrialization across emerging economies. Hence, industries such as manufacturing, automobile, energy, pharmaceuticals, consumer care products, food & beverage and various others have been witnessing significant growth to cater to the growing needs. AODD pumps are widely used in all these industries, as they are a critical part of transmitting fluids and slurries. Thus, the AODD pumps market is poised to experience a robust growth rate over the forecast period.

When considering the use of metal casings lined with corrosion-resistant thermoplastics, special consideration of the service conditions is critical. The following questions should be addressed when selecting the special material: How will the lining hold up under the flow conditions? How abrasion-resistant is the lining material? How significant is the danger of wear or pinholing, which might lead to corrosion of the metal or contamination of the product? These concerns become less significant as lining thickness increases, or with designs that use thick-sectioned, replaceable wet-end components.

To enable the handling of very big and heavy pumps, the testing bench features cranes that are capable of lifting pumps that weigh up to 20 tons (20,000 kilograms/44,000 pounds). The facility is also capable of producing maximum electrical power of 4 megawatts (Mw), which further allows it to test very large pumping units. The facility features motor-tension rates that range from low tension (0-690 volts) to medium tension (0-13,900 volts), which also attests to its ability to accommodate the needs of large pumps. Finally, a closed-loop system enables the accurate and reliable NPSH testing with water of both vertical and horizontal pumps.

According to Fact.MR’s analysis, demand for diaphragm pumps are likely to remain the preferred choice among end-users owing to their enhanced features, such as flexibility and isolation of the fluid chamber. Fact.MR estimates global sales of diaphragm pumps to surpass 2,000,000 units by the end of 2018. Increasing production of aggressive chemicals is resulting in the surging demand for Air Operated Double Diaphragm (AODD) pumps.

The movement of diaphragm A towards the centre of the pump generates a partial vacuum in the chamber, causing ball valve 1 to close while ball valve 2 opens as air pressure forces liquid from the inlet (‘I’) into the chamber.

If you want your AODD pump to handle corrosive chemicals or fluids with fluctuating concentrations and/or pH levels, then it’s vital to make the proper selection of pump bodies and internal pump components to avoid pump corrosion, ensure compatibility, and reduce maintenance requirements. For such applications, plastic pump bodies such as polypropylene, PVDF, Kynar and PTFE are often chosen on account of their chemical inertness. The highest chemical compatibility is offered by PTFE, which can generally be safely used with the most basic chemicals to the most acidic acids. It could be, however, that PTFE is an over-specification. Other materials such as polypropylene or PVDF may suffice. It therefore makes sense to refer to the manufacturer’s chemical compatibility guides for guidance as to which are the optimal pump materials to use for the chemical or fluid you are working with.

The big advantage of the selected NOVADOS H6 series pump (please see the short introduction at the end of the article) is its construction as a diaphragm plunger pump. This means the pump is completely leak-free without additional technical complexity, does not discharge emissions and thus meets the specifications of the Technical Guidelines on Air Quality Control (TA Luft). Schlüter is also impressed by the ease of maintenance of this pump and his employees in the maintenance department can perform many operations themselves on site.
