Pumps/Vacuum technology Companies – Innovations – Products A second example from the field of new, climate-friendly energy sources is the production of biodiesel: a fuel with many challenges. High-pressure pumps make an essential contribution towards the production of these environmentally friendly fuels. Biodiesel or fatty acid methyl ester (FAME) is a fuel that is equivalent in use to mineral diesel fuel. The chemical industry obtains biodiesel by transesterifying vegetable or animal fats and oils with monohydric alcohols such as methanol or ethanol. During production, the fatty acids contained in the oil are split off from the glycerol with the aid of a catalyst and chemically converted with methanol, i. e. esterified. In various steps, this process produces the fuel “biodiesel” as the main product and the by-product “glycerol”, which is used as a food additive and in medicine. The methanol is recycled back into the reactor. Fig. 5: Plunger pump P5-85 for the process industry Fig. 4: Electrically driven pump unit for the production of biodiesel In today's industrial, patented processes, so-called supercritical processes, various reactions take place simultaneously and within a few minutes. They achieve maximum yield and, thanks to the special process parameters, no longer require catalysts. For this purpose, highpressure pumps are used to pump methanol and fatty acids against high pressures. Depending on the production plant, pump capacities of up to several hundred kilowatts are required for these applications. The particular challenges for the high-pressure pumps lie in the properties of the pumped media: methanol, for example, has hardly any lubricating properties, while other media tend to crystallize early, which can severely disrupt pump operation and lead to reduced service lives. Local conditions, such as use in hazardous areas or particularly high or low temperatures, also place enormous challenges on the pump units and thus on their manufacturers. Compliance with local regulations, standards and certificates round off the requirement profile for the pump supplier. The many years of experience, the high level of expertise and the design refinements therefore characterize the robust and long-lasting pumps from URACA to the satisfaction of the customers. With an increasing variety of applications and growing requirements, the development of new products is of elementary importance. Based on this motivation, URACA has added compact pumps to the power ranges of 700 kW and 1200 kW with the two new pump types P3-85 and P5-85 and created a new pump series in the upper range. This adds two extremely compact plunger pumps to the product portfolio, the main features of which are their short design as well as the integrated gearbox. With a stroke of 100 mm and a rod load of 280 kN, the average piston speed can be kept relatively low. The Px-85 series enables an increase in performance compared to long-stroke machines of corresponding performance classes while at the same time complying with the API 674 limitation on average piston speed. The short design, the elimination of external gears and the simultaneous optimization of performance with respect to comparable gearless types enormously expand the range of applications to the benefit of the user. As a result, not only can several pumps be replaced by one in individual cases, the new series also opens up areas of application that previously had to be served by long-stroke and very slow-running types. In addition to saving space, these possibilities also lead to a reduction in costs compared to the complete ensemble with gearbox, converter and similar additional units.

Pumps/Vacuum technology Companies – Innovations – Products pressure pump in the 80 kW level presents itself to its future users. With its compact design, it opens up a wide range of applications. As the European market leader for sewer flushing pumps, URACA attaches particular importance to high power density and the longest possible running times with robust operation of the pumps. The wide acceptance therefore is due to this fact and the high reliability. Decades of experience in the development and construction of high-pressure plunger pumps, state-of-the-art technology and highest manufacturing quality with maximum vertical integration have made URACA a leading company in the industry. The newly developed highpressure pumps are continuing this successful course. URACA GmbH & Co.

Intelligent IoT solutions can help to reduce production downtime and to save a lot of money. OTTO is the digital service innovation by Busch Vacuum Solutions. It combines condition monitoring of vacuum pumps with attractive service packages. For high process reliability and less cost of ownership in factories. The Busch IoT Dashboard and the Busch Vacuum App track vacuum pump data permanently. With the information at hand, the performance can be analyzed, and processes optimized. Busch installs a proprietary sensor package at the vacuum pumps, which collects and processes data. The data is stored in the Busch cloud via a mobile con- nection. The IoT box constantly monitors process state and vacuum pump conditions. For example, the ambient temperature, oil temperature and the remaining time until the next maintenance of the vacuum pump. The IoT dashboard provides all collected performance data 24/7. The data is interpreted, and performance trends are shown. To optimize the production, Busch is providing a summarizing report as well as recommendations for more efficient operation. Based on data analysis, Busch is taking care of preventive maintenance and sends a service technician if needed. OTTO digital services by Busch come in three different packages tailored to the needs of the customer. Whether the customer wants to take care of the monitoring himself or wants Busch to take the lead. The suitable OTTO package detects appearing problems before they become a real problem. Risks and costs associated with unplanned downtimes are avoided and lead to optimum process reliability and higher productivity in factories. Even already installed vacuum pumps can be retrofitted with the Busch IoT kit.

Qdos ® Conveying Wave Technology (CWT) extends the capabilities of peristaltic pump technology with its unique Fluid Contact Element. This innovative assembly is subjected to very low stress levels. Thus, Qdos CWT pump offers longer service life than traditional tube-based designs combined with superior accuracy in chemical metering and dosing tasks, and the elimination of expensive ancillary equipment. This makes Qdos CWT an ideal solution for a large variety of chemical metering and dosing tasks, for example in water treatment applications. Qdos ® CWT pumps do not achieve their peristaltic action by operating a traditional tubing but by an unique assembly, the “Fluid Contact Element”. It combines an EPDM element rather than a tube, which acts against a PEEK track. The fluid is contained between the EPDM element and the PEEK track, and the rotation of an eccentric rotor displaces the fluid forward. In effect, the Fluid Contact Element offers the same basic function as the tube of a conventional peristaltic pump. As well as the elimination of vapour locking, the element delivers stable, reliable performance, even with fluctuations in ambient temperature and pressure. Furthermore, the robust mechanical design provides consistently high accuracy for the life of the pump. Fig.: The new OTTO digital services by Busch Vacuum Solutions reduce production downtimes.
