SEALS DELIVER BOTTOM-LINE SAVINGS
THE DUPONT KALREZ LS390 SERIES of perfluoroelastomer sanitary seals, available in the UK from Dichtomatik, have been designed specifically for use in sectors such as life science, food and beverage, and pharmaceutical.
Several problems can be experienced in sanitary seal applications, many of which are related to thermal and chemical resistance challenges, compression set (permanent deformation), and high static friction (stiction). These issues can lead to intrusion in the production line or dead space, which in turn elevates the risk of contamination or leakage.
The Kalrez LS390 series has been purpose-designed to overcome these common challenges by providing high hardness properties (Shore A3 88), low stiction, temperature resistance up to 220°C and outstanding chemical resistance to process chemicals, WFI (water for injection), and steam-inplace (SIP) and clean-in-place (CIP) processes. For users, these properties facilitate greater MTBR (mean time between repair), delivering bottom-line cost savings.

OPTIMAL PRODUCTIVITY AND CLEANLINESS
NATIONAL OILWELL VARCO (NOV) has made its new Hygienic Range pump commercially available in the UK. NOV developed the new pump to meet the food and beverage industry’s need for a cost-effective, reliable and hygienic solution that ensures optimal production levels while adhering to the highest standards of cleanliness. The pump adheres to the design standards of the 3A and EHEDG certification bodies to ensure that it is one of the most hygienic on the market. The gentle pumping action of the progressive cavity pump handles applications such as food processing, dairy, pharmaceutical, cosmetics and chemicals production. According to NOV, the Hygienic Range pump is cleaner and more cost-efficient than pin-joint pumps and other flexible joints consisting of one solid piece.
Titanium Flexishaft technology allows pump users to remove retention areas that can harbour and promote bacterial growth, improving hygiene and complying with food standards. The pump is tie-bar free to reduce the number of components and aid strip and inspection, while hygienic foot mounting holds the stator in place. In addition to easier maintenance and fewer expensive parts, the titanium Flexishaft is shorter in length than comparable steel pumps, increasing flexibility and allowing for its use in space constrained applications. With no wearing parts, the Flexishaft offers lifetime cost savings over conventional drive train designs and extends intervals between routine maintenance. NOV designed the Hygienic Range pump to suit varying conditions and to overcome challenges, giving users installation flexibility for clean-in-place and clean-out-of-place situations.
The Hygienic Range pump transfers solids up to 25mm in diameter and incurs minimal product degradation in shear-sensitive applications. It also efficiently moves viscous slurries and can handle thin liquids and corrosive applications.

AVOIDING CONTAMINATION
FLOTRONIC’S E SERIES PUMPS HAVE been designed to enable ease of cleaning for all product contact and non-product contact parts.
The 10-inch version, with 2-inch connections, offers a pump solution to customers with low to mid-range flow rate applications, while customers seeking flow rates as high as 500 ltr/min can use the 12-inch pump with ½-inch to 3-inch connections.
The 10-inch E Series pump has a support stand allowing the pump to be rotated for easy and effective draining. Gravity separates the ball valves from their seats in this inverted position allowing cleaning fluids to drain away from the delivery nozzle quickly.
The 12-inch E Series pump has check ball valve seats that are engineered to allow drainage without inversion. This avoids the need to rotate a relatively large machine.
Reinforced diaphragms are standard on the E Series. Reinforcing plates ensure the pumps can withstand cleanin-place (CIP) and steam-in-place (SIP) pressures up to 6 bar in a production line. This means the pumps can be cleaned in place using fully automated CIP units incorporating external CIP pumps, without the need to bypass the pump.
Tested to exacting performance standards by EHEDG (the European Hygienic Engineering & Design Group), the E Series is suited to use in any application where avoidance of product contamination is paramount.
