Additional costs may arise if pulsation dampeners are required to accommodate vibrations and surges in the piping systems. AODD pumps are very reliable since they have very few moving parts and components that can wear. They are easily dismantled for maintenance or diaphragm replacement. The main working parts are the valves, valve seats and diaphragms. Spares are generally fairly low cost, but it is vital to select the correct corresponding parts. For example, Neoprene is outstanding for general purpose as a low cost diaphragm that delivers the highest flex life. Teflon-based diaphragms are generally the most expensive, with other materials lying in between, so while the diaphragm used must be compatible with the fluid to be pumped, care should be taken to make sure that is not ‘over-specified’ leading to unnecessary costs.

The final thermoplastic material choice will depend on such factors as solids-handling and dry-run capabilities, space requirements, initial cost, maintenance costs, commercial availability and service experience with the product and vendor.

Developments in double diaphragm pumps have led to introduction of high speed and high pressure Air Operated Double Diaphragm (AODD) pumps in the market. These AODD pumps find applications in construction and chemical industries.

With approximately $12 million of revenue generated in 2018, All-Flo is expected to be accretive to margins of Dover and its Fluids segment. The acquisition is expected to generate double-digit cash Return on Invested Capital (ROIC) by Year 3.

Although Design Mark Industries keeps its chemicals in a vented, explosion-proof room, the supplier of membrane switches, keypads, and touchscreens sought to further improve the safety and efficiency of transferring acetone and acetate-based chemicals from 55-gallon drums into quart and 5-gallon containers.  The chemicals are used in the screen printing process of printed circuitry and graphic overlays. Production Supervisor Vincent Francisco ruled out manual pouring because of the potential of injury and lack of control in dispensing. Instead, he utilized a variety of traditional pumps including rotary, siphon, and lever-action, but found them all unsatisfactory. “I was replacing the pumps once or twice a year because they kept breaking down, delivered imprecise amounts, and were not designed as completely self-contained, sealed systems,” says Francisco. After considerable research online, Francisco decided to utilize a sealed chemical pump system from GoatThroat. “I consider using [GoatThroat] pumps a ‘best practice’ technique because the barrels remain upright and the entire system is sealed so there is never an issue with exposure or VOCs when transferring chemicals,” says Francisco. According to Francisco, the sealed pump system is intuitive to use because it operates like a beer tap. “Just pump the plunger a few times, open the spigot and dispense.  You have full control over how much is dispensed, even the tiniest amounts, or you can leave it open for a continuous flow.  It delivers the precise amount needed.” Francisco adds that the pumps are built for longevity. Over the past 11 years, he estimates that his company has saved thousands of dollars by eliminating the cost of replacement pumps. “I’ve only replaced one of our three pumps over that time due to constant use, and we could have used it longer,” says Francisco.   Allergy Laboratories Inc., a FDA licensed pharmaceutical manufacturer of biological extracts for the diagnostic testing and therapeutic treatment of allergies, also uses a sealed pump system to transfer acetone from 55 gallon drums to 1 gallon containers for a variety of processes. According to Charles Cheek, facility manager for Allergy Laboratories, the pharmaceutical chemical delivery process must be very clean and no foreign material can be introduced into the acetone.  Because acetone is highly flammable, he was concerned about using an electric pump that could potentially create a spark.  As a result, he decided to purchase a pump that had no electrical or moving parts that could create a hazard. “We’ve found GoatThroat pumps to be a much safer way to transport chemical liquids,” says Cheek, who utilizes a pneumatic adaptor accessory to supply pressure via in-house compressed air. “There is no spillage, splatter, overpouring, leaking, or VOCs because the system is self-contained. There is no sprayback and we do not get chemicals on our hands.  It is a nice, clean delivery system.”

New high-pressure processing (HPP) technology for fresh ground meat retains the natural appearance and texture during the HPP process. Meat companies, retailers and consumers can take advantage of the food safety benefits that HPP provides, as well as a more natural appearance and a 2-4 times increase in shelf life. This is a viable lethality step (FSIS Directive 6120.2) for fresh ground meat. While still pending USDA approval in the U.S., international opportunities exist. While fresh ground beef is the first application, it’s slated to expand to whole muscle beef, as well as poultry and pork in the future.

This article identifies and recommends popular ball, seat and diaphragm materials (internal pump components) and pump fluid sections (pump bodies) to perform in applications with varying fluid characteristics.The key to the safe and reliable operation of an AODD pump is correct configuration. This involves taking fluid characteristics into consideration, for example, pH levels, abrasiveness, temperature and fluid density. The chemical compatibility is also important; manufacturers often provide guides to ensure pump materials are suitable for the fluid being transferred. These same websites often feature online pump selector tools to assist in configuring a pump in a matter of minutes and with a few clicks of the mouse.

In order to better understand the benefits offered by AODD pumps, it is worth examining the way that these pumps work. Figure 1 shows how the two diaphragms in the pump (A and B) are moved from left to right and back again by directing compressed air alternately to them via a central air valve. 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.

After establishing the desired water rate per hectare, the chemical mix for the tank can be calculated using the tank volume and litres per hectare to arrive at the necessary mix of chemicals.

Change in pressure (ΔP) and suction duration should be optimized to assist needle drying after all liquid has been removed. Alternatively, some systems incorporate a separate pump to blow air over/through the needle to aid drying.
