Fig. 1 Analyzing vibration measurements on Omnitrend Center taken by Vibscanner 2.

It’s not a secret, that vibration on machines causes severe issues – not only on a long term perspective. Vibration, caused by any issue is the natural enemy of any rotating machine such as a pump. Due to the latest handheld high-speed data collector Vibscanner by Pruftechnik vibration of all kind on all kind of machine can be detected during the maintenance routine.

With the special software Omnitrend Center the measurement results of Vibscanner 2 (Fig. 1) can be analyzed deeply and used for an entire machine health program. But what measurements does the new high-speed data collector Vibscanner 2 deliver, how do you interpret these and how can you react on these measurements? Let us give you a quick kick-start into vibration analysis to help keep your pumps alive.

Augmented reality supports pump and valve service

Wednesday, May 9th, 2018 von admin

At this year’s Achema, KSB Service GmbH is, for the first time, presenting its new service concept based on augmented reality. It is all about working with data glasses linked with the Internet, or with a smartphone app. Via these devices users or technicians are guided during their service work by an expert per video and audio. The experts, looking into their screen at their usual service workplace, can assess the situation through the eyes of the person present at the site.

This helps instruct technicians who are not specialised in pumps, for example, to carry out common maintenance measures, step by step. Further, the data glasses can be used to transmit exploded views or screenshots that can then be viewed in the corresponding field.

KSB puts pumps into the Internet of Things

Thursday, March 15th, 2018 von admin

At this year’s Achema, KSB is presenting a new pump monitoring system called KSB Guard. Networked vibration and temperature sensors fitted directly to the pump make availability at plant level transparent. The system ensures that changes in the operating behaviour of the machine are detected at an early stage, and maintenance work can be better planned, without having to be on site with the pump. Unlike previous systems, KSB Guard is ideally suited for retrofitting. The sensor unit is attached to the bearing bracket or the drive lantern of the pump using a magnet and adhesive, and can be mounted during operation, with no need for changes to the machine. A battery unit, which is also supplied, provides self-sufficient power supply.

Innovations for wastewater pumping

Fig. 1

At the previous Ifat, Swiss company Egger presented a further development of their completely retracted Turo centrifugal impeller TA for raw sewage conveyance. To date, a large number of pumping stations that are burdened with high solid loads (such as fibrous materials, wet wipes, etc.) have been successfully equipped with them. Blockages could be eliminated or – under extreme load – reduced to a minimum.

At Ifat 2018, the company is now presenting a low-clog and 100% dry-running-safe centrifugal pump hydraulic system. A further development of the Eurodyn hydrodynamic shaft seal in conjunction with Turo Vortex hydraulics makes absolutely dry-run safe use possible. The pump hydraulics and shaft seal operate completely contact-free. In the case of wastewater pumping operations that comply with the regulations, the pump set as designed by Egger enables 4-years of maintenance-free operation.

Maintenance-in-place-solution for progressing cavity pumps

Monday, February 19th, 2018 von admin

Progressing cavity pumps from Allweiler can be delivered with an Optifix option. The pump can be disassembled in five steps, and eliminates the need to dismantle it from piping to change the rotor, stator, joints or shaft seal.

Designed to deliver superior speed and efficiency, Optifix’s easy exchange design is optimized for safe and streamlined inspections, parts removal and service operations. In wastewater treatment service, Optifix can reduce mean time to repair intervals by as much as 85 percent and boost pump service life by up to 500 percent when combined with patented Alldur stator solution.

Pump field services

Friday, February 2nd, 2018 von admin

Large pumps, such as those operated in the

  • oil and gas,
  • power generation and
  • water industries

perform a crucial role and represent a significant investment by the owner. Safeguarding these assets and maintaining efficiency and reliability are vital for the continued productivity of the application. Very often, when it comes to maintenance, the choice is between the original equipment manufacturer (OEM) or an independent service provider (ISP), but John Murray describes here that it is possible to have the best of both worlds.

KSB at Anuga FoodTec 2018 in Cologne

Wednesday, January 24th, 2018 von admin

In the limelight at the KSB Anuga FoodTec trade fair stand is, among others, the newly developed concept of a maintenance workstation for hygienic food pumps only. The so-called LSA (Life Sciences Applications) hygiene workstation is equipped with stainless steel surfaces, work benches that are easy to clean, and tools and clothing for use in this workstation only. Also, all lubricants supplied are FDA-approved. At the KSB stand in Cologne, such a workstation will be demonstrated by a service engineer performing maintenance work on a hygienic pump live at regular intervals.

Sulzer doubles capacity of high voltage testing to improve repair times

Thursday, January 11th, 2018 von admin

Performance testing of high voltage motors and generators is usually carried out to determine benchmark data following a major repair. However, increasingly, customers are requiring this information as part of a problem diagnosis or to verify performance figures for a component when its essential data has been lost. To keep up with growing demand, Sulzer has made a major investment at its Falkirk Service Center (Scotland) that will enable the test-bed load capacity to be doubled.

Until now, the Falkirk site has used a 1,250 kVA diesel generator that operates through two step-up transformers to provide 3.3 – 11 kV via high voltage switchgear to the test cell. This setup ensures a reliable power source for testing that is not affected by local demand on the power grid. The new investment will add a 2,000 kVA and a 700 kVA generator to the site that will be synchronized through a 4000A LV switchboard, as well as a new 2,500 kVA transformer, that will double the capacity of the test bed.
