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more frequently occurs at the end of a process like wastewater treatment when the waste sludge that has formed must be withdrawn.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).

Lewa: Follow-up order of another 20 pumps to Saudi Arabia

Thursday, December 14th, 2017 von admin

Lewa delivered 40 process diaphragm pumps to two large offshore platforms on the Persian Gulf in 2013. Lewa has got now a follow-up order to this 30 Mio Euro order – the largest in the history of Lewa. The follow-up order includes

  • 8 LGB2 Boxer pumps and
  • 12 LDH5 series process pumps

These pumps are used for transferring monoethylene glycol (MEG) from the Tie In Platforms (TP) to the Well Head Platforms (WHP) and on-site MEG injection. This injection is intended to prevent the ice formation in the drill hole that can occur during the formation of methane hydrate. The project will be completed in 2019.

The plant will increase the gas output from 70 million m³ up to 126 million m3 per day.

Metering pumps optimise cathode materials for lithium batteries

Saturday, November 18th, 2017 von admin

Solenoid diaphragm metering pumps type gamma/ X

Ternary oxide systems containing lithium guarantee a high energy density, long service life and high number of charge cycles for lithium storage batteries. Metering systems ensure the quality of the precursors needed for production.

The most important storage materials for lithium ion batteries are lithium nickel manganese cobalt oxides, or NCM for short. Various manufacturers in China have specialised in the production of the ternary precursors needed for this. Their appearance, particle size, size distribution, declared purity, beat density and many other characteristics are important to determining the properties of the sintered cathode end product. The manufacturers needed to find reliable and accurate metering pumps and systems that were able to meet the stringent quality requirements of manufacturing ternary precursors.

Almatec: AODD Series Now Available in Stainless Steel

Friday, October 27th, 2017 von admin

The Futur S/SH pump series is now available in 316 stainless steel with high surface finish for the transfer of pure solvents in the semiconductor industry.

Realizing the importance of reliable and contamination-free pump performance in critical semiconductor operations, Futur S/SH Series pumps are cleaned several times, then assembled and tested in a cleanroom line before being released for delivery. Futur S/SH Series pumps incorporate a “straight-through flow pattern” with only one wetted housing part (center housing) while the air control system and the air chambers are located in the side housings.

Tapflo: New series of diaphragm pumps

Wednesday, June 28th, 2017 von admin

The new TC pumps are fitted with LEAP – Low Energy Air Pump – technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction. LEAP uses a indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically.

The TC pump is able to start pumping at 0.1 bar without stalling. Key benefits are
