3 EXTRUSION PROCESSES For high-quality finished products Gear pumps optimize the extrusion process of thermoplasts as they supply the required melt very precisely and efficiently build up the tool pressure thus relieving the extruder itself from building up the pressure. This enhances the performance of the production line, improves the quality of the finished product due to reduced melt temperatures, and increases the lifetime of the extruder. In addition, pressure pulsations and pressure peaks of the extruder are eliminated or at least smoothened as the gear pump dampens such pulsations and peaks. Further benefits of the gear pump are that the chips produced during the cutting process can be recycled and that the pump supplies the melt very uniformly through the die, which in return ensures a constantly high quality level on the final product s side. In terms of processing quality and optical characteristics, products are subject to high standards. Another important aspect in manufacturing and processing of plastic material therefore is filtration, with the filter discharging impurities from the liquid plastic melt. Maag Pump Systems supplies the devices necessary for filtration in numerous fields of plastic production and processing. Permanent development processes improve these filtration devices and thus contribute to our customers and end users satisfaction concerning quality.

6 GEAR PUMPS We have the appropriate solution for every application The compact, durable gear pumps made by Maag Pump Systems meet highest requirements for thermoplastic applications. Thanks to optimized flow channel geometry, short and quality-supportive dwell-times are feasible even for temperature-sensitive products. The gear pumps are easy to handle and guaranteee reliable and quick start-up and shutdown processes for processing extruders and compounding extruders. High conveying stability and task-oriented configuration in combination with a high level of reliability support production stability for repeatable processes. The Maag gear pumps convey the medium in a low-pulsation way even when exposed to high differential pressures. Special materials and material processing steps as well as innovative bearings, mainly made from highly wearresistant tool steel, allow high revolutions with corresponding high throughput rates. The excellent degree of efficiency is also due to the flow-optimized design of the flow channels. The modular design and three different series meet varying requirements: extrex GP is the allrounder, extrex HV features a 25% higher pumping volume, and extrex HP is capable of dealing with a differential pressure of up to 400 bar. The trudex gear pumps have been especially designed for high-pressure applications. These high-pressure gear pumps ensure reliable supply quantities at up to 700 bar. This guarantees highest possible product quality. Special, spur-toothed shafts and special sliding bearings ensure excellent efficiency factors while the conveyed medium is stressed only to a very little extent. Optional accessories such as cooling for shaft seals, melt pressure sensors, or temperature sensors complement this efficient gear pump line. 6

Such melt valves are applied as diverter valves, safety valves, or start-up valves in plastics production and extrusion and compounding applications. The sturdy design and a reliable electric, liquid, or steam-driven heating system ensure leak-free and trouble-free operation for years, e.g. as start-up aid for underwater pelletizing processes or when start-up material has to be discharged in extrusion applications. When set to production, the melt stream flows down the melt channel and reaches the next downstream station. In order to divert the melt to start-up, the bolt is activated hydraulically. This switching can be slow or quick, depending on the individual process control-related needs and is ensured through various hydraulic systems. DV Start-up valve Channel diameter: 25 to 100 mm Operating temperature: Up to 350 C Operating pressure: 500 bar Advantages: Compact dimensions Any installation position feasible 11

15 RETROFITTING FOR EXTRUSION SYSTEMS Improving quality and results The expac system made by Maag Group reduces negative impacts such as the pulsation of an extruder. Pulsations may lead to dimensional deviations of up to 5% on the final product due to wear or added recycling material. The expac system significantly reduces such deviations and thus improves product quality. The quality of the material, and of the product later on, also depend on short dwelltimes of the melt inside the pumps, screens, and mixing elements. The speed of the entire process and resourceconscious usage of energy define process productivity. expac systems are mainly intended to retrofit already existing systems but can also be integrated into new systems. expac consists of: Drive unit with gear motor and drive shaft Pump Control system, installed in switch cabinet Corresponding instruments Interfaces to already existing systems Screen changers, if applicable 15

19 Maag Group has business roots extending back more than 100 years. The foundations for today s Maag Pump Systems AG were laid by Max Maag in the year 1910, beginning with gear manufacture. The business grew, and in 1928 the company s factory in Zurich shipped its first gear pump. In the decades to follow, Maag engineers developed ever more sophisticated and capable gear pumps. Today, these process pumps are in operation around the world, serving customers in the plastics, chemical, petrochemical and food processing industries. At the start of the new millennium, Maag Pump Systems expanded its product range to include high-performance screen changers and large-area filtration units so that, since this time, it has been able to offer complete systems. After more than six decades serving the plastics industry, it is hard to even imagine this market without pelletizing systems from Automatik Plastics Machinery. Originally founded in 1947 as Automatik Apparate- und Maschinenbau GmbH, the company began developing strand pelletizing systems from its earliest days, bringing the first automated strand pelletizer to the market in the 1960s. The 1970s saw a further burst of innovation, particularly the company s launch of the first underwater strand pelletizer in the middle of that decade. In the late 1990s, Automatik went on to bring its unique drop pelletizing system for low-viscosity products to the market, filling yet another industry need. The company completed its product portfolio in 2003 with the introduction of its SPHERO underwater pelletizing technology. Since this time, Automatik has offered solutions covering a comprehensive range of pellet shapes, operating throughputs and production requirements. The paths of these two extraordinary companies have crossed many times over the years, as both have long been providers of complementary, superior quality systems and components to the plastics processing industry. With their merger in 2010, Maag Pump Systems and Automatik Plastics Machinery were brought together under the umbrella of Maag Group, offering complete and highly efficient pro duction solutions from a single source. Maag Group has been a part of Dover Corporation, a U.S. industrial conglomerate, since
