Why "Like-For-Like" Won't Be to Your Liking

04-Jan-2018 05:33:00

If you’re taking the opportunity of the summer months to maintain, repair or replace your heating pumps, there’s one important point to remember. If you want to cut your energy costs, a “like-forlike” replacement might save you some specifying time, but in every other way it will cost you.

A like-for-like swap isn’t only a bad idea. It might actually not be possible. After all, surveys reveal that up to 60% of pumps in plant rooms and pumping operations are obsolete. So you may not be able to replace your old pump with the same again, even if it were a good idea. Which it definitely isn’t.

Pump Bearings: Designed for Reliability and Long Life

07-Dec-2017 06:26:00

New bearing development from SKF that promises improved speed, reduced friction, better reliability, and longer service life for pumps.

Often to be found at the heart of a process or manufacturing operation, the ubiquitous pump is frequently taken for granted, being expected to operate continually while receiving minimal maintenance over the course of its life. A pump's performance will change over time, depending upon its operating conditions, its materials of construction, hydraulic design and mechanical robustness. From the perspective of mechanical design, bearings – and more particularly the type of pump motor bearings selected - will have a considerable impact on a pump's long term reliability, its energy efficiency and life expectancy.

When Failure Should Not Be an Option

16-Nov-2017 05:39:00

There is a clear correlation between improving the reliability of critical assets, extending their Mean Time Between Failure (MTBF), and reducing their maintenance costs. Bring asset management into the equation, and there can also be valuable additional benefits – such as avoiding catastrophic failures, minimising unplanned downtime, rationalising spares purchasing, and reducing the overall unit cost of production. How many more reasons do you need to adopt best practice?

The first step towards effective asset management is Condition Monitoring.

Firstly, this enables you to identify potential asset failures and to plan repairs or swap-outs to avoid disruption to production. Secondly, because you identify issues at an early stage, it ensures you can rectify them before a catastrophic failure results.

Automated Accuracy from Seepex

31-Oct-2017 04:26:00

SEEPEX have launched a new Smart Dosing Pump (SDP), enabling customers to input one parameter –the flow rate required – and then the integrated PLC makes adjustments automatically when necessary using information from a flow meter on the pump outlet.

Operation is simple: the SDP comprises a progressive cavity pump with an intelligent inverter drive which is programmed either locally via an HMI or centrally via a fieldbus interface. The SDP can also be controlledvia analogue/digital I/Os either locally or remotely by a PLC.

Xylem Launches 5th Generation Hydrovar for Complete Range Offering

21-Sep-2017 05:28:00

Offering energy savings of up to 70 per cent, Xylem, a leading global water technology provider, has launched the Hydrovar 5th Generation variable speed pump drive with a wealth of new features and new additions to the range.

Known for its robust and quality design, Hydrovar is now available across 21 models ranging from 1.5kW-4kW single phase to 22kW 3 phase – ensuring there is an option for each and every application. New features include a separate wiring compartment, with a dedicated cover to ensure wiring components are protected. What’s more, the electronic power component is potted, meaning that there is increased thermal dissipation and robust protection against vibration and condensation issues with the ability to operate down to an ambient temperature of -10oC.

Designing in Hygienic Solutions from the Beginning

04-Sep-2017 05:23:00

In tough working environments like the food processing sector, pumping delicate viscous fluids – that contain solids, is a day-to day occurrence. When it comes to specifying equipment therefore, it’s imperative that businesses specify products that are not only fit for purpose, ensuring the quality of the finished product – but also maintain impeccable hygiene standards. Here Paul Winnett at Xylem talks through the importance of choosing the right pump solution and some of the key features to look out for.

As with most manufacturing sectors, the food and beverage industry has a number of issues to bear, not least in its continuing commitment to stringent hygiene standards but also to ensuring the continued efficiency of their plant. In turn, the pump industry and wider markets have continued to evolve their products in line with the changing demands and now offer a plethora of potential solutions to meet industry needs.

Beating the Drum for Liquids from Lutz

03-Nov-2016 09:01:47

If you use any kind of liquid other than tap water on your site, here’s a problem you’ll face on a regular basis. How do you easily and safely get the liquid out of its delivery container to where you actually want to use it?

It’s almost certainly been delivered in a drum or barrel - typically 5L or 25L carboys, 200l drums or IBCs. That’s convenient for delivery and storage, but not so convenient for getting the liquid out.

The containers are too big to tip and pour from, and if they’re full of toxic chemicals or flammable liquids that’s not a safe option anyway.

So how do you beat the drum challenge?

Challenging the Norm with the Munsch Mega Mammut Pump

26-Apr-2016 08:17:31

The Pump Centre Conference and Exhibition is now only a few weeks away - held at the Telford International Centre the event on 12th May – and the theme of the event is Pump Innovation, Challenging the Norm.

So with that in mind ERIKS, one of the main event sponsors, have teamed up with German pump manufacturer Munsch Chemie-Pumpen GmbH to display mother of all pumps at the event - The Mega Mammut.

The Mega Mammut is the world’s largest armoured centrifugal pump for aggressive and abrasive service environments. With a motor rating of one megawatt, it can deliver up to 5,000 cubic metres per hour at a maximum pump head of 40 metres. The heavyweight  tips the scales at over 3 tonnes or even 8 tonnes when adding the motor and base plate.

Efficiency You Can Rely On from Grundfos

24-Feb-2016 10:21:12

When it comes to pump selection there are a number of factors you need to consider, and by no means least the selection of supplier you can trust to do the job. That’s where Grundfos come in.

Whilst they have a full range of pumps for any application, their end-suction pumps are multi-purpose pumps suitable for a variety of different applications demanding reliable and cost-efficient supply and are useful for a number of key applications such as:

  • Water supply
  • Industrial pressure boosting
  • Industrial liquid transfer
  • Heating/district heating
  • Air-conditioning
  • Irrigation

What's the Point of Pump Efficiency?

26-Nov-2015 14:54:00

Every pump has a Best Efficiency Point (BEP). And finding it will not only mean the pump will use the least energy for the highest performance. But also by operating your pump at or near its Best Efficiency Point, it will also mean increased reliability, so it pumps better, for longer.

Operating far off its BEP was one of the problems with the pumps examined by ERIKS at a waste water pumping station, which had suffered  a number of premature and catastrophic pump failures.

The site was spending £180,000 per annum on pump repairs, and there were also a significant number of emergency call-outs, which were only adding to the high operating cost of the pumping station. They requested a Root Cause Analysis, to try to identify and resolve the issues.
