New series of Low Energy Air Diaphragm Pumps

Tuesday, October 16th, 2018 von admin

Tapflo named its new pump series “TC Intelligent pumps”. The main step forward is the LEAP technology – ‘Low Energy Air Pump’. This is a patented technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction.

“LEAP uses an indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically”, explains Colin Wreyford Technical Director at Tapflo.

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 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).

Wilden: New Diaphragms for Industrial Applications

Monday, May 22nd, 2017 von admin

The new Chem-Fuse diaphragms are specifically designed for industrial applications. The Chem-Fuse diaphragm technology eliminates the potential leak point at the outer piston as well as outer piston abrasion. This is crucial for industrial applications that pump abrasive or dangerous fluids. The diaphragm design also offers easy cleanability for faster changeovers between products. These features allow Chem-Fuse diaphragms to enhance productivity, reliability and safety.

An additional benefit of Chem-Fuse diaphragms compared to other reduced-stroke integral piston diaphragms is the use of a large integral piston and full-stroke shaft that provides greater efficiency. This design allows Chem-Fuse diaphragms to provide up to 100 % increased flow and suction lift compared to other diaphragms.
