The target application for this positive displacement quaternary diaphragm pump series is the continuous dosing of high-value additives in the food and beverage and personal care industries (e.g. to add concentrates to a fluid stream for soft drinks) as well as for in-line dilution. These ‘QuattroTec’ called pumps can provide a consistent flow that results in a constant and continuous dosing of ingredients in hygienic processes.

At this year’s BrauBeviale trade fair KSB is going to showcase the youngest generation of its hygienic Vitachrom single-stage close-coupled pump. It now features both the standard connection and, as an option, an 8-mm flexible tube connection for liquid supply to the mechanical seal. With its electropolished stainless steel surfaces and almost complete lack of dead volume the pump is very easy to clean by CIP/SIP. The type series is EHEDG-certified and all materials used comply with FDA and EN 1935/2004 standards. An Atex-compliant version is available.
Pure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria, a critical consideration for hygienic applications. This patented design also provides an unbroken fluid-contact surface for CIP capability and reduced contamination risks. Pure-Fuse combines food-grade plastics and elastomers with a stainless-steel core using no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. In addition, by eliminating the outer piston Pure-Fuse diaphragms experience reduced abrasion, which results in longer diaphragm life.
At this year’s Anuga FoodTec in Cologne, Fristam Pumpen will be presenting its newly developed FPC pump series, which is particularly suitable for transporting media with a high gas content, for handling intermittent product inflow and for CIP-return applications. The new hybrid pump scores with a high degree of efficiency, low sound emission and low energy consumption.
The new 76 mm (3”) Full-Stroke Integral Piston Diaphragm (FSIPD) is made for use in Wilden’s Saniflo FDA pumps, as well as its Original, Advanced and Advanced FIT series of air-operated double-diaphragm (AODD) pumps. These diaphragms are well suited for hygienic applications because they are constructed of food-grade Santoprene™, and the integral piston is completely encapsulated within the TPE material, meaning there is no outer piston that can trap fluid and particles.
The result is a durable, highly cleanable diaphragm assembly that features a large integral piston and a full-stroke shaft that enables it to maintain the same stroke length as conventional Wilden diaphragms. The diaphragm’s full-stroke design increases product displacement per stroke, which translates into improved suction lift, greater flow rates and higher efficiencies than experienced when using pumps that operate with reduced stroke diaphragms.
The carbon-graphite components provide superior lubrication in most environments, and are ideal for pumping liquids with poor lubricating qualities, strong chemicals that attack metals, and to pump air, vacuum, combustion products and gasoline vapors. Metallized Carbon’s carbon-graphite vanes, rotors, and end plates are used in such dry running applications as automotive anti-smog pumps and gasoline vapor pick up pumps, breathable air pumps and vacuum pumps. In-liquid applications include vending machine beverage pumps, fuel and liquid chemical pumps, and medical liquid pumps.
Wilden has received Patent No. 8,496,451 from the United States Patent and Trademark Office for its Full-Stroke Integral Piston Diaphragm (FSIPD). “The FSIPD provides the clean-ability that customers need and adds the flow rate and suction-lift performance they want. In addition, customers will be happy to know that a Wilden FSIPD is about half the cost of a PTFE IPD,” says Robert Jack, Development Engineer, Wilden Pump and Engineering.
Constructed of Wil-Flex™ (Santoprene®), FSIPDs do not incorporate an outer metallic plate that requires the pump to be cleaned manually. Instead, the metallic plate is integrated into the material itself, resulting in a diaphragm design that uses the same shaft and inner piston as Wilden’s rubber and TPE diaphragms to maximize performance. Wil-Flex FSIPDs are easy to install and do not require inverting of the diaphragm for installation. Wilden FSIPDs do not use any adhesives that could get exposed to the pumping media.
The new Tapflo pump series is certified by EHEDG, the European Hygienic Engineering Design Group. The aseptic pump series will come in three sizes. The first to be launched is the smallest, with a maximum flow of 425 litres per minute.
