4 Reasons to choose AODD pumps for chemical processes

Thursday, September 20th, 2018 von admin

Technical paper by Erik Solfelt:

Thanks to its simple yet innovative design, the AODD pump has proven to be able to consistently meet the demands of chemical processors while building a reputation as a go-to pumping technology where basic fluid-transfer capabilities are required. The AODD pump, which possesses a stable of notable operational characteristics, has become a first-choice technology for chemical manufacturers who are searching for a pump that meshes cost-conscious air consumption with reliable and safe production rates.

Sanitary AODD designed to meet exacting standards

Tuesday, September 11th, 2018 von admin

12″, 10″ and 7″ H Series versions

Flotronic Pumps’ original 10” ‘H’ Series pump was designed to meet the exacting hygiene standards of 3-A Sanitary Standards, Inc (3-A SSI) and to be used in processes where hygiene is a priority. Since the launch of the 10” pump in 2015, the range has been expanded to encompass 7” and 12” versions, both of which are 3-A SSI accredited. Pipework connection sizes are now available from 1” – 3” allowing greater flexibility.

AODD pumps with a solid plastic design

Friday, July 20th, 2018 von admin

The new C-Series pumps have been specifically developed by Almatec to be a cost-effective alternative. The housing parts are tightened to each other via housing bolts. All of the C-Series’ bolts are tightened together against a diaphragm-sized ring on each side of the pump.

This design distributes the forces of the housing bolts onto the housing parts evenly, providing a consistent flow of forces that increases bolt torque and improves pump safety.

AODD for hygienic processes and sanitary applications

Monday, June 25th, 2018 von admin

Flotronic’s ‘E’ Series pumps are air operated double diaphragm pumps (AODD). These pumps have proved themselves unmatched when tested to exacting performance standards by EHEDG (the European Hygienic Engineering & Design Group). The ‘E’ Series offers peace of mind for the food, beverage, dairy and pharmaceutical industries – and any environment or process where avoidance of product contamination is paramount.

The 10” version with 2” connections offers a pump solution ideal for customers with low to mid-range flow rate applications while customers seeking flow rates as high as 500 litres per minute will find the 12” pump with 1½” – 3” ideal.

What To Consider When Selecting a Filter-Press Pump

Technical paper by Peter Schüten:

High-Pressure Air-Operated Double-Diaphragm (AODD) Pumps Deliver The Operational Advantages Necessary For Optimized Operation Of Chamber Filter Presses.

In many industrial processes that feature the handling of liquids, the substances that are being transferred may occur in an aqueous or “muddy” state, with the liquid portion needing to be removed. This liquid-removal stage may take place during the production process – for example, in the filtration of edible oils or yeast solutions – but it more frequently occurs at the end of a process like wastewater treatment when the waste sludge that has formed must be withdrawn. Since the disposal of such sludges is calculated based on weight and volume, their thickening and drying is particularly lucrative for the processor. During the thickening and drying process, the sludges are treated using chemicals and/or physical processes so that the waste sludge forms into flake-like solids. After adjusting the pH level to neutral or alkaline via the use of milk of lime, the subsequent dewatering process separates the water for disposal, with the remaining volume of sludge significantly reduced.

The simplest technology for this process involves collection and thickening of the sludge through the use of gravity. However, it is significantly more effective to use technical drying methods via processes such as centrifuges and evaporators, or more commonly, chamber filter presses (Fig. 1).

This new AODD pump is transferring blackwater onboard the hospital ship Africa Mercy, the largest civilian hospital ship in the world. Founded in 1978, Mercy Ships is a global charitable organization that operates a fleet of hospital ships specially designed for use in developing nations.

Many people in Africa have little or no access to healthcare. For nearly 40 years, Mercy Ships has delivered free services valued at more than $1 billion – directly impacting more than 2.5 million children and families. As a state-of-the-art hospital ship, the Africa Mercy brings volunteer medical teams and sterile operating rooms directly to people who would otherwise go without care.
