For a manufacturer of ball valves, it is very important to know the characteristics of flows inside a ball valve. In addition to the flow coefficient, there are other points that a manufacturer must consider. Due to progress in the areas of flow visualization and computational analysis, it is now possible to observe the flow inside a ball valve. The flow visualization can provide flow patterns of a ball valve, especially the cavitation phenomenon. This aids manufacturers in innovating better-suited valves with higher operational functions. The advancements made by companies in flow visualization make them an excellent choice for controlling various applications and sometimes they are preferred over any other valves that have less control in the throttling applications.

  With Flexcore screw pumps Leistritz Pumpen GmbH provides a wide application window and more freedom of installation. Flexcore is a series screw pump capable of adapting to a wide range of installation situations. With a single basic casing for all pressure levels, flow directions and standards. “It sets new benchmarks, especially in tough applications such as power & energy, marine, chemical and petrochemical applications,” explains Philipp Rossow, Product Manager at German Leistritz Pumpen GmbH. “As a specialist for demanding pump solutions, Leistritz has a clear focus: We want to optimally meet the specific expectations and needs of our customers with extraordinary products and solutions. With Flexcore, Leistritz has now created a globally groundbreaking innovation – a pump class that for the first time unites qualitative, functional and economic aspects in an extremely flexible, quickly available series product. Its intelligent design with the exchangeable cartridge unit is particularly impressive when it comes to installation and maintenance. Compared to conventional pumps, this modular concept is worldwide unique.” Initially, Leistritz is launching pump sizes for flow rates of 7 to 564 l/min. The series will successively be expanded by eight additional sizes with flow rates up to 1,600 l/min. Depending on customer requirements, Flexcore is available in cast iron or steel casing.

  Ifat 2020 (7 - 11 September 2020 in Munich) will see the KSB Group present its new submersible motor pump of the Amarex type series as one of its novelties on display. The pumps are employed in applications like waste water and sludge treatment as well as the transport of stormwater. They can handle waste water with long fibres and solid substances, fluids containing gas as well as sludges, service water and grey water and are equipped with either free-flow impellers (F-max) or open two-vane impellers (D-max). So pump users can choose the right impeller type depending on their requirements: low waste water flow rates at high heads and high flow rates at lower heads. Pump variants featuring D-max impellers are optionally available with D-flector which significantly increases resistance to clogging. A multitude of material and mechanical seal variants ensures that the user can transport a wide range of corrosive and abrasive fluids. The impellers’ non-clogging feature markedly reduces maintenance requirements compared with conventional designs and the pumps’ high levels of hydraulic efficiency combined with high-efficiency IE3 motors make for low energy consumption during operation. The type series has a maximum head of 42 metres and a maximum flow rate of 320 m3/h. When designing Amarex, engineers attached great importance to the pumps achieving a long service life. This is ensured by a generously dimensioned motor, robust rolling element bearings and a corrosion-resistant stainless steel shaft. An environmentally friendly, non-toxic oil fill provides continuous lubrication of the mechanical seal. As is common practice with this type of pump, installation in the pump sump is effected via a duckfoot bend. A large range of adapter claws also allows the use of duckfoot bends from other manufacturers so that a change of make is possible without requiring a major installation effort. Sealing between duckfoot bend and the pump discharge flange is by a newly developed, absolutely water-tight and durable U-profile ring. Users also have several options when choosing the arrangement for placing the pump on the duckfoot bend: They can opt for guide hoop, guide wire, single guide rail or twin guide rail arrangement. The pumps are designed for ease of repair. At the end of the pump’s life cycle, most of components can be dismantled and recycled. www.ksb.com Read the full article

Pumping systems from Andritz make an essential contribution worldwide towards a safe, sustainable and, above all, technologically optimized water supply. The mega-city of Peking also trusts in this technology and quality. Hui Nan Zhuang pumping station located to the south-west of the Chinese capital is equipped with eight double-flow axial split-case Andritz pumps. Pumping systems from Andritz make an essential contribution worldwide towards a safe, sustainable and, above all, technologically optimized water supply. The mega-city of Peking also trusts in this technology and quality. Hui Nan Zhuang pumping station located to the south-west of the Chinese capital is equipped with eight double-flow axial split-case Andritz pumps. Two sets of three pumps plus one standby unit each supply a common pipe with a diameter of four meters. Hui Nan Zhuang is the only pumping station in the middle water supply channel of the Chinese milestone project "South-to-North Water Diversion", with a total length in the region of 1,200 kilometers. The pumps supplied by Andritz convey a total of 60 cubic meters of water per second over a distance of approximately 60 kilometers to Peking. Nine smaller pumps of this same type will also be used in the new drinking water plant on Cap Bon. They are the ideal hydraulic machines for use as piped water pumps in water treatment or drinking water pumps in water supply systems. Depending on the final location of the Tunisian pumping station, it will handle a flow rate of 648 to 900 m³/h at heads of 20 to 63 meters. For this purpose, each pump is fitted with a 55, 160 or 200 kilowatt motor. With an efficiency of up to 91 percent, these double-flow split-case pumps help to save valuable energy. All of the pumps are equipped with a twin-flow radial impeller that achieves very favorable NPSH levels. Thanks to the axial split-case design, maintenance work is quick and easy. Equipped with a double-flow radial impeller and an inline casing, the pump can be installed horizontally or vertically. If mounted horizontally, the motor(s) can be positioned on the left and/or on the right. Besides design and delivery of the pumps and spare parts, installation and commissioning work on site will also be supervised by Andritz personnel. Completion of the entire project is scheduled for June 2019. Equipped for the future In addition, the pump casing already has the connections needed for intelligent sensors to monitor operating reliability and performance as well as other key indicators in line with Industry 4.0. These special pump monitoring packages that can also be retrofitted compare operating conditions against the nominal curves. These include variable speed curves such as head, efficiency, motor rating or NPSH in relation to flow rates. In addition, temperature, vibration and electrical analyses are conducted. All data can be analysed in the software or exported to various file formats. The files are stored in an Andritz Metris data base that can be installed on a local server or remotely in the Andritz Metris Cloud (Microsoft Azure). Based on these data gathered, accessible by the customer and by Andritz condition monitoring experts, service recommendations can be provided at any time for operation of the plant and the pumps installed. By standardizing data acquisition with these tools, the customer’s experts can also communicate more effectively with Andritz and improve plant performance at the same time. By networking our customers’ own specialists, also with Andritz experts, our IIoT technologies become the basis for Internet-of-People (IoP) solutions. This value-adding connection results not only in professional processing of the data gathered, which improve and maintain the performance of the plant, but make it possible in addition to respond and react even better to climatic and other factors that have an adverse effect on the water supply.
