Easy clean metering pump for hygienic duties
The personal care, cosmetics, pharmaceutical and biotechnology industries can now take advantage of the high levels of precision metering offered by Bran + Luebbe’s ProCam pumps following SPX Process Equipment’s introduction of a dedicated sanitary model that is EHEDG compliant.
Using food-grade components that have ultra-smooth surfaces and modified flow geometries that permit clean-in-place (CIP) of the membrane pumpheads and valves, the new ProCam Sanitary can deliver up to 500l/h at pressures of up to 20 bar. Applications for which the pump can be used include perfume solutions for creams and soaps, nutrient solutions in biochemical processes, buffer solutions in chromatography and solvents and extracts for pharmaceuticals.
“ProCam pumps are designed specifically for the purpose of metering precise volumes of liquids into process streams, which is not the case with other types of positive displacement pumps,” said Bran + Luebbe UK pumps manager Steve Digby. “As many as six pumps can be combined for the online production of complete formulations. They offer a wide range of flow rates and different methods of adjusting the flow thereby optimising plant efficiency.”
The ProCam Sanitary’s cleanability and corrosion resistance is achieved by using specially selected materials with polished finishes. Depending on the application, components coming into contact with the product are made from high grade stainless steel with a roughness factor (Ra) of 0.8µm. In all cases, the PTFE dual layer membranes and valve seats are FDA certified.
“The construction of the membrane pumpheads and the valves has been modified for hygienic applications by improving the flow characteristics to ensure complete cleanability,” said Digby. “In addition, pump connections are available with clamp or dairy pipe fittings and we have also modified the paint coating procedure, using FDA approved paint, to satisfy pump applications. As a result, the ProCam Sanitary can be used with CIP up to 150ºC and SIP with saturated steam of at least 120ºC.”
The ProCam Sanitary is highly adaptable and where fitted with electric stroke length adjustment and integrated controller with 4.20mA input/output signals, can be incorporated into a close-loop system. These models are also available to comply with ATEX 94/9/EG.
