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.

An ‘alignment free’ pump

Wednesday, November 29th, 2017 von admin

It is imperative that pumping systems are designed and operated in a way that reduces the amount of harmful stress placed on components. One area that has been difficult to achieve and maintain is shaft alignment. Failure to properly align a pump’s mating shafts will eventually lead to challenges associated with shaft fatigue and failure, resulting in compromised pumping-system uptime, reliability and safety. This can then result in costly maintenance or even knock the pump out of service and halt production.

Focused on this problem, Blackmer developed GNX Series sliding vane pumps, which are called by the manufacturer “industry’s first alignment-free”. It is a reduced-speed pump for use in both portable and stationary applications.

Sulzer in Glasgow Sets the Standard in Maintenance and Repairs

Wednesday, November 22nd, 2017 von admin

Increasing pressure to reduce costs and optimise performance is causing many industries to reassess the way in which they tackle maintenance issues. Sulzer’s Glasgow facility has been quick to expand the capabilities and expertise of its staff to ensure additional benefits for customers and help meet these demands.

Scott Tyre took on the Glasgow service centre manager’s role in early 2017, after joining Sulzer as Contracts Manager in June 2016. He comments: “The Glasgow Service Centre is continuously improving to keep pace with its customers’ demands and the staff pride themselves in delivering the best possible technical service. Our challenge is to provide expert engineering support along with concise customer communication and dialogue, 100% of the time.”

Simplified servicing in beneficiation plant

Thursday, November 16th, 2017 von admin

Until January 2017, a copper beneficiation plant in Zambia was using pumps from six different manufacturers, including units from Netzsch. Attributable to the large number of different models, this resulted in a steadily growing inventory of similar spare parts and maintenance procedures. Thereby, the effort and costs for necessary maintenance of the pumps were constantly increasing as a result. Following a thorough review of the reliability and service life of its pumps, the plant operator decided to simplify its spare parts inventory and maintenance – and only use pumps from Netzsch as a single supplier.

The Zambian company replaced 36 pumps for polymer applications and saved 1 million dollars by reducing its spare parts inventory as well.

Technical Paper: Pump refurbishment package focuses on energy efficiency

Wednesday, August 23rd, 2017 von admin

A two-stage horizontal split-case pump, with Vesconite inter stage centre bushing

An Australian company that specialises in both on-site and off-site pump refurbishment is finding that energy efficiency is an important driver in its refurbishment packages – and has included Vesconite bushings as part of its energy-reducing refurbishment package.

FITT Resources’ Daniel Hechter says that electricity costs in Australia, at 25+ AUS c/kWh, are among the highest costs globally.

As a result, when the company retrofits 30 to 35-year-old pumps, besides increasing the life of a pump, there is a focus on increasing the energy efficiency of the pump. The company’s retrofitting is programme orientated and includes a number of interventions to in-crease energy efficiency by ensuring that flow is better and that less electricity is used.

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.

Predictive Maintenance for Process Control

Wednesday, November 23rd, 2016 von admin

Manufacturing, utilities, and oil & gas companies have been gathering troves of raw data since well before the Internet of Things was a thing. For decades, machines like pumps have collected big analog data about voltage, motion, sound, acceleration, vibration, and more at the farthest reaches of the network. But industries have never had the compute power and technology to process that data and turn it into real-time, data-driven decisions at the “edge” (on premise, away from the data center and closer to the “things”) —until now.

An example of predictive and preventative maintenance solutions that can be delivered in the real world using NI’s PXI and sensors on a Flowserve industrial pump can be found here.
