Finish Thompson AODD pumps are used in a wide range of industries, including construction, mining, electronics, chemicals and food processing. The pumps are self-priming, so they can run dry without any damage, and because they are powered entirely by compressed air, there is no need for electricity.

They are ideal for use in remote or hazardous locations, not to mention explosive environments. They require low amounts of maintenance and low cost of ownership, completing an attractive package.  Let’s take a look at their cost-saving and energy-efficient properties.

Pumping Waste Fluids with Finish Thompson AODD Pumps: The pumping of waste fluids is an important requirement in a host of different industries. Air Operated Double Diaphragm pumps triumph over other pump designs such as those with close-fitting or rotating mechanisms where abrasive slurries can cause extensive wear to functioning parts. As a result, this can cause significant restoration costs and could suspend productivity. Because of the size of AODD pumps, these issues rarely occur.

Fewer Moving Parts: AODD pumps contain fewer moving parts than many other types of pumps and are easy to set up. There are no shaft seals or packing boxes involved. The diaphragm is a dynamic seal that converts the pneumatic pressure on one side to a fluid pressure on the other. Discharge flow rates are adjusted by controlling the air inlet or the discharge flow, so no complex control systems are required.

Emptying Waste Containers: Waste fluids are frequently stored in containers, which then have to be transferred to other containers, such as a tanker, for removal from the site. Finish Thompson AODD pumps are well suited to this type of application because they are inherently dry self-priming, i.e. capable of drawing up liquid even when installed above the source liquid level, unlike centrifugal pumps, which require an initial charge of liquid. Unlike most centrifugal and displacement pumps that fail if they run dry, AODD pumps have the ability to run faster without damage when operating dry.

Materials Matter: The versatility and range of applications that can be accommodated by AODD pumps are due in no small part to the wide range of materials of construction both for the pump body and the diaphragms. There are many materials available that are developed by individual pump manufacturers for use in their own pumps that are often derivatives of these materials.

Cost of Ownership: If a plant isn’t suitably designed for the application of a Finish Thompson AODD pump, the pump could end up costing more to run than it should. Having said that, the cost of ownership of the pump itself can be broken down into investment and installation costs, maintenance and upkeep costs (including labor and spares), and energy costs as well as waste removal and disposal costs.

Purchase costs will naturally depend on the size of the pump and the materials of manufacture. However, installation costs are minimal since pumps can be positioned wherever there is adequate space for them, even submerged if the liquid is compatible with the material of the pump.

Energy costs for the pump come from the consumption of the compressed air required to power the pump. Since compressed air is a relatively costly utility in many plants, requiring compressors and air distribution systems this represents the main running cost for an AODD pump.

However, AODD pumps can be used in areas either where electricity simply isn’t available, or in hazardous areas where electrical supplies are forbidden. This enables AODD pumps greater flexibility over centrifugal and positive displacement pumps.

Since there are few components that require maintenance, it is relatively straightforward to refurbish AODD pumps, increasing their lifetime and further decreasing the cost of ownership.
