Pump breakthroughs in efficiency and ease of use
Modern pumps have to be able to perform efficiently and with minimum maintenance while pumping materials that often can be highly valuable and corrosive. Sean Ottewell reports.
Die modernen Pumpen müssen effizient und mit minimaler Wartung Leistung abliefern, während Materialien gepumpt werden, die oft sehr wertvoll und korrosiv sind. Sean Ottewell berichtet.
Les pompes modernes doivent être capables de fonctionner efficacement et de nécessiter le minimum de maintenance tout en pompant des matériaux souvent de grande valeur et corrosifs. Selon Sean Ottewell.
A
ir-operated double diaphragm (AODD) specialist Wilden has launched the new Pro-Flo SHIFT air distribution system (ADS) for use in its Advanced
series bolted and Originalseries clamped AODD pumps. The company says that the Pro-Flo SHIFT
ADS represents a significant breakthrough in energy efficiency within the AODD pump category as plants continue to look for ways to reduce air consumption and reduce their carbon footprints. Thanks to its novel design, the patent-pending system allows Wilden AODD pumps to achieve up to a 60 per cent savings in air consumption over all competitive AODD pump technologies, while providing more product yield per standard cubic foot per minute (Fig. 1). “The Pro-Flo SHIFT represents a giant
leap forward in the energy efficiency and performance of AODD pumps. The simple design of the ADS doesn’t require any additional bolted-on equipment or bulky electronics, allowing operators to keep the same compact footprint,” said Chris Distaso, director of engineering for Wilden. While the Wilden

Pro-Flo SHIFT dramatically improves energy efficiency, it also costs 50 per cent less than an electronically actuated ADS, is submersible, and features plug-and- play operation. Its robust design makes it ideal for use in harsh operating environments and includes ATEX compliance for use in potentially explosive atmospheres. It also has fewer operating parts,

which equates to less downtime and simple maintenance. With no electronics, its design is well suited for the harsh environments typically found in industrial applications. Meanwhile Thimonnier, a world leader in
the design and manufacture of flexible pouch packaging machines, has integrated MasoSine EC25 pumps from Watson-Marlow Pumps into a new machine designed for packaging béchamel sauce. The pumps successfully convey the sauce to dosing nozzles without mixing or shearing the product. “The main priority,” explains Frédéric
Roumanet, design office manager at Thimonnier, which is based near Lyon, France, “was to meet requirements for hygiene and gentle product handling.” MasoSine pumps do not have any valves,
and their four chambers are sealed. This makes them ideal for fluids containing fragile pieces or particles, such as sauces and soups. Thimonnier had already contacted Watson- Marlow in the past about an application for
