Monitor your pump online – at any time, at any place

Fig. 1

The generation of maintainers who check the condition of pumps on a daily basis by listening and touching the equipment is dying out. Nevertheless, pumps must operate reliably. To solve this problem, BestSens has developed the Bearing Monitoring System, BeMoS for short (Figure 1).

BeMoS monitors roller bearings in machinery and plants from the very first second of operation. What is so special about it is the underlying technology:

Extensive additions to Siemens pump converter

Monday, November 27th, 2017 von admin
The Sinamics G120 is the universal drive to address the widest range of application requirements such as pump drives. Siemens is extending its portfolio of Sinamics G120 converters to include a new frame size, the FSG with voltage ranges from 380 to 480 volts (V) and from 500 to 690 V.
This addition means that the innovative PM240-2 Power Modules now cover the entire power range up to 250 kilowatts (kW). The extremely compact design and standard integrated optional features such as integrated DC link reactor or integrated filter to achieve category C2, enable substantial space and cost savings in the control cabinet.

Technical Paper: API-all-steel coupling with optimised performance

Friday, November 24th, 2017 von admin

Marc Egelwisse

In the Arpex all-steel multi-disk coupling the Flender GmbH, a 100 %-held Siemens subsidiary, is marketing a coupling that has proved itself over many years. Marc Egelwisse, product manager for Arpex couplings, and his team have further developed this series with a focus on three aspects:

  • increase in the specific power,
  • optimisation of the areas of application and
  • reduction of complexity of the type series.

The results show it was worth it:

  • 70 to 100 % higher torque,
  • 40 % greater angular misalignment,
  • 10 % higher maximum speed and
  • 14 instead of the 42 design variants existing hitherto.

“Because of the high torque capacity and the optimised speed and bore capacity of the new N-Arpex we are confident that we are offering what is at present the world’s best-performing coupling”, says Egelwisse.

Siemens: I/O extension module for converters

Thursday, October 26th, 2017 von admin

For the smallest converter in its portfolio, the Sinamics V20, Siemens is now offering an extension module for the capture and output of digital and analog signals. The Sinamics V20 I/O extension module is mounted on the converter using Plug&Play technology, and provides two additional input and output interfaces, each for 400 volts., increasing both the flexibility and the scope of the Sinamics V20. Using connecting ports on the front and back, the extension module can also be combined with additional accessories from the Sinamics V20 portfolio. These include for instance the BOP (Basic Operator Panel) and the BOP interface module.

Siemens: All-steel multi-disk couplings acc. API and Atex

Friday, June 23rd, 2017 von admin

Siemens presented an additional series in the range of torsionally rigid all-steel disc couplings: the new N-Arpex coupling with improved performance characteristics. An optimized disc pack and a revised component design facilitate the transmission of higher torques and speeds as well as a higher bore capacity with standard hubs. All-steel couplings can be used in all applications that require reliable torque transmission in set-ups with shaft displacement.

Sulzer: Repair of variable speed drives reduces costs and downtime

Thursday, April 20th, 2017 von admin

As the legislation surrounding the efficiency of electric motors continues to tighten, the volume of variable speed drives (VSDs) in service increases. Often specified by the motor manufacturer as part of the original installation – or retrofitted to improve efficiency – the drive contains both hardware and software that is designed to work with a motor in a specific application. So, what happens if the drive ceases to operate? Brian Park, Regional Sales Manager for Scotland at Sulzer, looks at the advancing technology and the maintenance processes that need to keep pace.

KSB: New drives reduce variant complexity of pumps

Thursday, April 6th, 2017 von admin

At this year’s Hannover Messe KSB is presenting a new, smart drive solution for fixed speed pumps. With the new MyFlow Drive, which is fully compatible with Industry 4.0, the fixed speed levels at the motor can be set to individual requirements. This provides the user with planning reliability as the flow rate of the pumps can be increased or decreased quickly and easily.

Siemens: Digitalization package for next motor generation

Tuesday, April 4th, 2017 von admin

With the latest generation of its Simotics SD (Severe Duty) motors, Siemens is offering a digitalization package to address the future challenges facing the world of drive technology. The new design is based on a robust, compact gray cast iron lowvoltage motor with high power density. Its future-oriented energy efficiency concept is designed to provide a competitive boost to customers and users. Their extreme resistance makes the Simotics SD low-voltage motors suitable for applications in harsh environmental conditions involving exposure to dust, vibrations or aggressive atmospheres.These benefits make the motors ideal for applications in the petrochemical and general process industries.

KSB motors IE5 classified

Wednesday, March 22nd, 2017 von admin

The KSB SuPremE motor made by the Frankenthal pump manufacturer KSB has been IE5 classified since January 2017. The motor meets the requirements of IE5 (IEC/TS 60034-30-2), the highest of energy efficiency classes for variable speed electric motors; compared with IE4, motor losses are reduced by a further 20 percent.

Unlike conventional synchronous motors this drive is made without any magnetic materials such as rare earths that are categorised as critical raw materials since their extraction causes severe environmental impacts in their countries of origin.
