The high level of usability of AODD pumps in these diverse applications comes from the pump’s unique operating features.
Over the years, though, AODD pump technology has also evolved from what has been called a “glorified Shop-Vac” into one that can be used as a process pump in even the most delicate liquid-handling applications. This so-called “mud to blood” operational versatility now makes AODD pumps ideal for a full array of industries and applications, from mining to hygienic processing, dangerous chemicals to food-and-beverage products.
The high level of usability of AODD pumps in these diverse applications comes from the pump’s unique operating features, including:
- Dry-run capability
- Seal-less design
- Deadhead capability
AODD pumps also benefit from the use of an air-distribution system (ADS) that gives the operator infinite control of the amount of air that flows through the pump, as well as the product flow rate, as if the pump had a built-in variable frequency drive (VFD). Motor-driven pumps, on the other hand, need an actual VFD in order to operate as efficiently.
Almatec AODD Pumps
Almatec has given traditional AODD technology new legs with the implementation of many different kinds of materials of construction, such as stainless steel, cast iron, machined polyethylene and PTFE (Teflon®). The polyethylene and PTFE models also make the pump intrinsically safe, which makes it truly safe for pumping dangerous chemicals and other liquids in an environment where an ATEX rating is required. Many Almatec AODD pumps also have the option of adding a barrier chamber system, which optimizes leak detection and prevention.
The diaphragms in Almatec pumps have always been designed from a PTFE point of view, resulting in a diaphragm that has a large diameter and short stroke with low flexural load, which ensures uniform product delivery regardless of the material used in the diaphragm’s construction. Additional diaphragm-material options include EPDM, PTFE/EPDM composite or NBR.
All Pumps supplies a wide range of air operated double diaphragm pumps which can be customised to suit your applications.
