Improved diaphragms easier to install available in a flat profile design, so there is no need to invert the diaphragm when rebuilding a pump.
The improved elastomer diaphragms from Wilden.
Wilden has recently improved the design of its Wil-Flex Diaphragms
to allow for easy installation. The Wil-Flex diaphragms are now
The diaphragms are made of Santoprene, a thermoplastic elastomer that links EPDM (ethylene propylene diene Monomer) rubber and polypropylene. They are suitable for for use in paint and coatings applications due to long flex life, ability to easy handle abrasion and wide swing in pH levels. Because of their thermoplastic qualities, Wil-Flex
diaphragms have inherent tensile strength and do not need fabric reinforcement. The diaphragms are currently available for use on the Advanced Series Metal 25 mm (1 in) bolted stainless steel and aluminium, 38mm (1-1/2 in) bolted stainless steel, and 76mm (3 in) bolted stainless steel and aluminium models. Wilden’s Advanced bolted pumps also feature the Pro-Flo X air distribution system. www.wildenpump.com

Nanotechnology for industrial seals
Richter Chemie-Technik GmbH, the German pump and valve manufacturer and part of the US-based IDEX Corporation, is asking clients to register their pumps on the company’s UK website.
Brisbane, Australia-based nanotech specialist TenasiTech Pty Ltd has developed a nano-composite thermoplastic polyurethane system for use in seals which, it says, can increase the operating time of pumps and lower costs.
"We're about to launch a new series of PFA-lined pumps into the UK market and want to get in touch with our existing customers,” said Lutz Rosin, marketing executive at Richter. “We've become aware that imitations of both our pumps and our parts exist within the market, use of which will obviously affect any warranties." "With the appointment of our new UK distributor, Billinghambased Tomlinson Hall […] we're re-launching our products into the UK and are looking for a
more direct dialogue with existing customers.” The company will enter all the registrants into a draw for the 32Gb iPad later this zummer. Richter pumps are suitable for use in European chemical, petrochemical and pharmaceutical industries and other sectors where corrosive, hazardous, contaminated, pure and ultrapure media are used. www.richterpumps.co.uk
Richter’s range of corrosion-resistant pumps.
In tests, the nano-composites showed improvements in mechanical strength, creep resistance, compressive set and barrier properties. Creep resistance improvements were up by 67%, and compression set gains up by 45%. The nano-polyurethanes also performed significantly better after exposure to elevated temperatures for extended periods. “The performance gains from our nano-additives are directly relevant to seals, giving their users the potential of longer mean time between failure and the possibility
of pushing operating temperature ratings further for polyurethanes, which is a historical weakness for this class of polymer,” said managing director Richard Marshall. The nanotechnology involves dispersing nanofillers into the host polymer’s chemistry. It originates from research at the University of Queensland and a number of patent applications are in progress globally. According to TenasiTech, it can be produced on an industrial scale. “We have partners in the northern hemisphere for applications other than seals, but we are now actively seeking a partner to develop product in this exciting market,” said Marshall. www.tenasitech.com
Pumps suitable for solar-cell manufacturing Almatec says that the solidblock construction of its E-Series air-operated diaphragm Pumps make them suitable for use in solar-cell manufacturing.

cations found in the manufacture of solar cells, the company says. PE has a high abrasionresistance, as much as seven times higher than polypropylene (PP) and 1.6 times higher than steel. In addition, the pumps have high chemical resistance, making them suitable for transfer of solar-cell manufacturing process’s
chemical supply, including acids and caustics, so that the pump’s internal parts will not become corroded by abrasive media or dry particles. E-Series pumps are created from a solid plastic block that is mechanically machined. This heavier construction allows the E-Series pumps to operate without “wandering,” which can
occur to lighter models during oscillating-pump use and lead to product leakage. The series consists of three solid housing parts: a centre housing and two side housings that are held together with bolts that are tightened against a diaphragmsized ring on each side. www.almatec.de
