Siemens extends synchronous-reluctance drive systems

Tuesday, April 24th, 2018 von admin

Siemens is extending its portfolio of Simotics synchronous-reluctance motors to include the two new shaft heights, AH90 and AH225. With these new additions, the company is addressing calls from renowned manufacturers of pumps.

The motors are available in a power range of 0.55 to 45 kW, and now also with rated speeds of 1,500 and 3,000 min1. In conjunction with the recently launched Sinamics Reluctance Control License, precise encoderless closed-loop torque control is possible down to a standstill. The license enables field-oriented (vector) closed-loop control even when at a standstill – reliably eliminating the possibility of the synchronous motor “stalling” at any time even if the load inertia is not known.

Pump monitoring with Atex certification

Monday, April 23rd, 2018 von admin

At this year’s Achema, Allweiler will exhibit its intelligent condition and operation monitoring system (hall 8.0, booth D63). Known as IN-1000, it is now also available with Atex certification for use in EX zones. IN-1000 was developed specifically for Allweiler pumps that are used in operationally-critical and environmentally-sensitive applications in chemical engineering.

The IN-1000 can be used for a wide range of condition monitoring applications, from simple, single-pump installations to complex, multi-pump systems while improving safety and reducing operating costs simultaneously.

VDMA at Achema: Pumps + Vacuum pumps meeting “Industry 4.0” demands

Tuesday, April 17th, 2018 von admin

The future pump and vacuum pump is intelligent and digitally integrated, according to manufacturers joined at VDMA Pumps + Systems as well as VDMA Vacuum technology. At present manufacturers are developing an administration shell based upon existing information models. This shell, the digital twin, contains all data specifying a pump. „All requested realizations as for example an OPC UA companion specification can be directly deducted from information out of the administration shell. This is evident when developing a pump to meet “Industry 4.0” demands,“ informs Christoph Singrün, managing director at VDMA Pumps + Systems, in the run-up to the Achema in Frankfurt.

Converter handling simplified by new module for wireless commissioning

Tuesday, April 17th, 2018 von admin

The new Sinamics G120 Smart Access Module enables the wireless connection of mobile devices such as tablets, smartphones or laptops over WiFi to the Sinamics G120, Sinamics G120C and Sinamics G120P pump converter series, making for considerably simpler converter handling.

The module is set up in a few simple steps using a conventional web browser and any standard operating system. The web server functionality eliminates the need to download any additional software. With its intuitively structured user interface and menu guidance, the module offers outstanding user convenience.

Thought-through coupling solutions bring noticeable advantages

Technical paper by Jochen Pelzer

The coupling of drives with work machines like pumps, fans and compressors is simple – at least at first glance. Because, while for selection of the right coupling knowledge of torque and speed are theoretically sufficient, practice shows that plenty of experience and high-quality products increase availability and reduce service costs.

New plunger pump head reaches up to more than 1,000 bar

Friday, April 13th, 2018 von admin

The plunger pumps feature an integrated gear, which enables very compact construction with maximum efficiency.

For the purpose of upgrading a cracker in a Chinese refinery a total of five plunger pump skids should be brought into operation by Lewa. Those in charge of the project opted for three triplex and two quintuplex plunger pumps in accordance with the API 674 standard. These pumps are equipped with the new KMC-L pump head with reduced clearance volume. This head consists of a single forging: The suction manifold is integrated as a result, allowing for a reduction in the sealing surface and thus in any potential leak points. An additional advantage is the fact that the suction side can be designed to handle backpressure, eliminating the need for a safety valve in the suction line. The new design makes it possible to realize pressures up to 1,075 bar. All pumps in use have been produced in Germany and mounted to a complete system in the Chinese plant.

These plunger pumps have a drive output of 260 kW and a flow rate of 25 m3/h. The suction pressure loss of the pump heads is very low, therefore a low suction pressure is needed and it is often possible to operate without a booster pump.

From pipe to component ready for installation

Thursday, April 12th, 2018 von admin

Individually produced, made to measure, in very small quantities or as a series – for years Butting from Knesebeck in Germany has been well known as a reliable supplier of special components ready for installation. In the course of time, countless product variations have been developed and manufactured together with the end customer – sometimes in series production.

True to the motto “more than pipes” the longitudinally welded stainless steel pipes from Bunttings in-house production usually serve as primary products for the components ready for installation. Corrosion resistant pipes, manufactured specially for the individual customer order, are used to produce these components. Thus special sizes or particular tolerances can be taken into account, such as production by internal diameter.  As part of prefabrication, laser, welding and forming technology are possible, as are cutting and surface processing by grinding and blasting, and combinations of these.

Pumps for wet flue gas desulfurization

Tuesday, April 10th, 2018 von admin

A cement factory in Texas was among the first in the USA  to install wet flue gas scrubbers in order to reduce the sulfur dioxide emissions. This is a demanding application for pumps because the gypsum slurry that “scrubs” the gas is highly abrasive and corrosive.

Special pumps with housings and impellers made of mineral cast prove to be a perfect solution here.

Wet Flue Gas Desulfurization Scrubber systems are a vital component in various industries due to strict environmental regulations. First applications were coal fired power plants and waste incineration plants. Today, other industries utilize wet scrubbers in their day to day operations as well to scrub flue gas emissions from burners that utilize coal as a fuel source.
