When sealing with silicones, the accuracy of the melt flow is the major requirement. Precision metering does not only presuppose the fast and reproducible operating point setting, it also requires a low-pulsation feed-in of the conveyer medium. Once again, Oerlikon Barmag gear metering pumps offer considerable advantages since the gears are correspondingly designed and precisely manufactured. Adding to the requirement of highest accuracy, metering pumps in silicone applications have to deal with high-viscosity media and high temperatures. Oerlikon Barmag pumps are designed for viscosities up to 1,500 Pas, back pressures up to 200/250 bar and operating temperatures up to 225 °C.

▪ Hygienic design for food, cosmetic and pharmaceutical applications ▪ Easy integration into automated processes due to compact design ▪ Length and weight savings compared to existing pumps ▪ Short cycle times ▪ Non-destructive dosing of solid containing materials with diameter of up to 20 mm ▪ Volumetric dosing and filling, regardless of viscosity ▪ For low to high viscosity materials ▪ Long service life even with abrasive and shear sensitive materials ▪ Continuous dosing, pulsation free ▪ Precise filling with high repeatability ▪ Linear relation between dosing volume and rotational speed ▪ Programmable suck-back prevents dripping or stringing of product ▪ FDA compliant elastomers ▪ Wetted components are autoclavable ▪ Stainless steel ▪ Optional flushing connection for optimum results with CIP ▪ Easy cleaning and maintenance due to quick assembly and disassembly options

The ViscoTec Hygienic Dispenser is available in 3 different sizes, allowing for volumes of 0.35ml up to 5.1ml per revolution. The smallest of dosage volumes can be perfectly dosed with a deviation of only +/- 1%. In addition to FDA-compliant components, and an EHEDG-compliant hygienic design, is the possibility of automatic cleaning via additional connection outlets. The cleaning medium is applied via the outlet in order to carry out automatic rinsing. Alternatively, the new dispensers can be disassembled quickly and cleaned manually. As in all dosing systems from ViscoTec, the VHD uses the proven endless piston technology based on the use of eccentric screw technology. For the VHD, many characteristics have been optimized and specially enhanced for use in the food and cosmetics branch. Among other things, the interior of the dispenser has been analysed and redesigned: the goal being to avoid dead volume and thus prevent contamination through harmful micro-organisms.

Generally, dosing pumps are referred to as oscillating displacement pumps with adjustable stroke length. Depending on the requirement the driving mechanism can be equipped with hydraulically actuated diaphragm. Electrically driven pumps offer besides the stroke length adjustment a further possibility to adjust the delivery flow by modifying the motor rotation speed. For a small delivery flow and a low delivery pressure, electromagnetically driven pumps are nowadays the devices of choice since they can simply be adapted to the process requirements by modifying the stroke frequency manually or through an external control (pulse or analog) signal.  Electromagnetic LMI pump. Flow rate: up to 76 l/h. Pressure: up to 20.7 bar For several years microprocessor-controlled dosing pumps with stepping motor are part of our portfolio. This pump model has a lot of possibilities and options for adjusting the delivery flow and monitoring the delivery rate. The driving mechanism offers additional
