Chemtech World Expo – February 14-17, 2017 – is one of the largest events for the chemical industry. 600 exhibitors from 20 countries expect up to 40,000 visitors. At the same time eight international conferences and about 150 speakers are offered. In the German pavilion, the German community stand, organized by the VDMA, the company Bungartz will present the concepts of its problem-solver pumps at stand C6A, which also have a high intrinsic safety:
- Wear and corrosion resistant pumps for the fertilizer industry
- Pumps with hydrodynamic shaft seal
- Continuously dry running magnetic driven pumps for liquids with large solids contents
- Cavitation-free pumps with an NPSH value <0.1m
KSB has been contracted to supply 22 power station pumps for the new Vietnamese Long Phu-1 power plant. The plant’s two 600 MW units are currently being built by a Russian engineering contractor. The complex is situated 20 kilometres east of Soc Trang city, on the right bank of the Hau River.
Included in the order are six boiler feed pump sets. The main and associated booster pumps are driven by 15,200 kW high-voltage electric motors. A geared variable speed coupling installed between the main pump and the motor varies the speed to achieve different operating parameters. Each pump set has been designed for a maximum flow rate of 1,200 m³/h and a head of 4,400 m. The boiler feed water temperature is expected to be 175 °C. To reduce energy consumption, the seven-stage pumps are equipped with optimised hydraulic systems which have proven their quality many times over.
Sohar SWRO Company LLC is the EPC Contractor for Sohar IWP and has signed several contracts with Sulzer to supply pumps for the new 250 000 m³/day independent desalination plant in Sohar, Oman. Commercial operation is scheduled for 2018.
The contracts include the manufacturing, testing, packaging, and installation supervision of the main centrifugal pumps. Seawater intake for the plant will be provided by Sulzer’s three big SJT vertical turbine pumps that will be installed at the nearby industrial port pumping station.
The new Gea Hilge Hygia hygienic pump range made its first public appearance at the trade fair BrauBeviale 2016 in Nuremberg (Germany). It combines the characteristics of the single-stage centrifugal pumps Hilge Euro-Hygia and Hilge F&B-Hygia in one product line, and will open advantages for pump users in maintenance, service, and spare parts stocking.
The new Gea Hilge Hygia range is part of the Gea Varipump line. The pumps are suitable for a wide range of operating points and tailored to the customer’s individual requirements. They stand out for their excellent surface finish and the complete absence of pores in the product contact area. Thus, they meet the high hygiene standards of the beverage, food and pharmaceutical industries.
At the end of October 2016, the Integrated TV & Video Association ITVA presented their famous award for the 21st time. The silver award was given to “The new gamma/ X” animation films from ProMinent.
Designed for continuous operation on thin liquids with a viscosity up to 500 mPa s, the new generation pumps are suitable for process and CIP/SIP applications. They offer a very gentle and steady product treatment, which makes them an ideal solution also for sensitive product applications like milk and cream products or yeast. The pumps can handle flow rates up to 160 m³/h and pump heads up to 75 mWc.
The new Etaline L are small close-coupled pumps in in-line design. They are available in 12 hydraulic sizes with motors from 0.12 to 3.0 kW. The pump series covers flow rates of up to 95 m³/h and discharge heads of up to 21 metres.
The cast casings and the mechanical seals are designed for operating pressures of up to 10 bar. The connections at the suction nozzle and discharge nozzle can be either flanged or threaded, depending on the size. A confined O-ring reliably seals the casing, also in fluctuating operating conditions.
The less the amount of material to be mixed, the greater the challenge for the dosing system: Due to the World’s increasing miniaturisation in areas such as electronics and the associated high demand for ever smaller and more precise dosing, preeflow has developed the eco-DUO330. This system provides the answer to numerous questions from application engineers, material manufacturers, plant engineers and product developers. Be it in medical technology, optics and photonics, the manufacture of electronic components or in the field of biochemistry and the production of semi-conductors.
Adherence to the exact mixing ratios of the 2 component materials and its precise coverage can greatly influence the processes and applications from time to time. Even small deviations can negatively affect the desired results. Compounds harden only partially, adhesive bonds do not reach their load limit and, in the worst case, chemical reactions from the materials could have an unforeseeable impact on the user.
With the newly developed eco-DUO330, dosing quantities of 0.005 ml (per shot) is achievable. Irrespective of temperature, time, pressure and viscosity – dosed as a dot or bead. Therefore, the smallest quantities can be created at that very moment. The microprocessor-controlled system creates a dosing accuracy of ± 1 % and repeatability of over 99 %. And this whole process is reliable and reproducible.
Wells, waste water treatment plants, water reservoirs, elevated tanks, water distribution networks, collection channels, rainwater retention basins, waste water treatment plants – the water industry operates a complex network infrastructure for water supply and waster water disposal.
The high fixed costs of these infrastructures force those responsible to an intensified view of the variable costs. This can only be done by the energy efficient operation of all technical units, in particular the pump system. The basis for this is the transparency by the recording and analysis of the relevant energy data. However, pumps in small and medium-sized water treatment and sewage treatment plants generally do not operate in the view of a technician. And the distance to a central control panel makes the connection of a cable impossible from the aspect of costs.
