Quiet operation with robust twin-screw pump Designed for handling fluids that are sensitive, abrasive and either high or low viscosity, the Alfa Laval Twin Screw Pump is suitable for use in hygienic applications in the dairy, food and beverage, and personal care industries. Built on a robust platform that meets stringent hygienic standards, the pump is capable of handling both product transfer and cleaning-in-place (CIP). Its low pulsation characteristics and solids- handling capabilities reduce the risk of product damage, improving product quality. Maintenance is simplified and process uptime is increased. easy seal replacement with the pump in place is made possible by a cartridge seal with a front-loading, self-setting design. This maximises process uptime and minimises maintenance costs. An optional seal service kit programme adds maintenance flexibility and cuts operating costs.

“The Twin Screw Pump is the ideal choice for both high and low viscosity liquids, all pumped perfectly with complete reliability,” said John Walker, pump portfolio manager. Additional benefits of the Twin Screw Pump are that it is quiet and virtually pulse-free, as well as being smooth and gentle during operation. These characteristics make the pump a suitable choice for handling sensitive products.

The Alfa Laval Twin Screw Pump features a clean external stainless steel finish with profiled elastomers and mechanical seals fully surrounded by the product. Designed for maximum cleanability using FDA-conforming materials, the pump is both EHEDG- and 3-A certified. An optional ATEX version enables use in hazardous zones. Alfa Laval provides specialised products and engineering solutions based on its key technologies of heat transfer, separation and fluid handling. Its equipment, systems and services are dedicated to assisting customers in optimising the performance of their processes. The solutions help them to heat, cool, separate and transport products in industries that produce food and beverages, chemicals and petrochemicals, pharmaceuticals, starch, sugar and ethanol. Alfa Laval Kolding A/S – Denmark alfa.laval@alfalaval.com www.alfalaval.com The PurgEye Desk is manufactured with HFT’s PurgeNet™, for the in-line connection of additional accessories, that allows the weld purge monitor to control welding systems based on oxygen level, as well as to provide indi- cations of high and low oxygen levels. Applications for the PurgEye Desk can be found in ultra-clean conditions, such as in cryogenics, food, drinks, semi- conductors, aerospace, pharmaceutical sectors and other industries where tita- nium is used.

Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimising contamination risks. Its suction performance and lift capability with low NPSHR provide installation flexibility and increase product recovery. Quick and

Zero-colour titanium welds from HFT Titanium is the metal of choice in a variety of industries due to its corrosion resistance to acids, chlorides and salt. It has a wide continuous service temperature range, from liquid nitrogen (-322°F) to 1,100°F and the highest strength-to-weight ratio of any metal. manufactured by weld purging expert Huntingdon Fusion Techniques (HFT), reads oxygen levels from 1,000 ppm to levels as low as 1 ppm (highly accurate to 10 ppm), ensuring titanium welders achieve perfect oxide-free, zero-colour welds.

Ron Sewell, chairman for HFT, said, “Titanium parts are often welded inside a welding enclosure, where the entire atmosphere surrounding the weld can be kept at a controlled level of oxygen. The PurgEye Desk is ideal for use with welding chambers and flexible enclosures, as well as with orbital welding machines and other automatic welding systems.”

Titanium is a reactive metal, so when heated it will react with surrounding oxygen, and discolour and lose its corrosion-resistance properties. In critical welding applications it is therefore crucial that the oxygen level surrounding the weld is purged of oxygen to 50 ppm or lower. The innovative PurgEye ® Desk, a new weld purge monitor designed and
