Thinking Sealless – Process Industry Informer Podcast

Process Industry Informer is a leading magazine for managers and process engineers working in the chemical, food and beverage, pharmaceuticals and utilities industries.  They run an active podcast channel.  In a recent episode David Clark, our Senior Engineering Manager, discusses the evolution of magnetic drive sealless pumps, from their introduction by HMD Kontro over seventy years ago to the very latest developments and materials that are driving the industry forward.

Thinking Sealless Pumps Podcast

He reports how a step-change in design, driven by technology advances and innovative materials has seen the emergence of a new level of agility and flexibility while future-proofing products against ever-more stringent regulations.

The topics included in the podcast

  • Industry compliance – meeting ASME/ISO/API standards
  • Innovations including new bearing technology and use of composites
  • CSA/CSI launch – a complete redesign to meet current and future needs
  • The necessity to get products to the market more quickly
  • Future requirements for sealless magnetic drive pumps
  • Greener production – energy efficient savings of 15-20%

HMD Kontro has always been at the forefront of innovation, which is aimed at delivering what the industry needs. These include:

  • New bearing technology and use of composites:  The last ten years has seen the advent of new materials including composites to increase the efficiency and reduce the heat being put into pumps to increase their overall robustness.
  • Silicon carbide and ceramic matrix composites:  Silicon carbide has been used for over twenty years. However, over the last five years, there has been a move to use ceramic matrix composites as an alternative. This further improves the robustness of the pump.
  • PEEK composite materials:  HMD Kontro produced the ZeroLoss containment shell made from PEEK composite materials almost ten years ago. This provides a more efficient and robust alternative to traditional metallic containment shells.

The CSA/CSI Launch – A complete redesign to meet current and future needs

The catalyst for change and the development of the new range was aftermarket feedback and user comments combined with many years of experience. This led to the complete redesign of an existing product to meet current and future industry needs, involving going back to the drawing board as just a product ‘refresh’ was not going to go far enough.

A complete rethink was needed, resulting in the incorporation of the best of existing pump knowledge combined with new materials, technologies and insights. The result is a range of highly flexible pumps, which are totally configurable with the end user receiving delivery of pumps quickly, often within days.

The pumps can be brought to the market faster thanks to a modular design and configured kits of parts, allowing maximum flexibility in specification and interchangeability to minimise stockholding and to deliver shorter lead times.

Greener production

At the same time, new approaches and materials have been harnessed to improve energy efficiency by 15-20% combined with the peace of mind from total containment, as well as assisting in predicating performance issues.

How does the future look for sealless magnetic drive pumps?

There is more and more acceptance of the magnetic drive sealless pump and the future will see a demand for larger pumps with parts such as internal bearings needing to be bigger and this will demand investigation of further alternative bearing materials.  Containment shell technology is seeing more acceptance, including ZeroLoss and non-metallic shells. It is expected that HMD Kontro will continue to innovate and move the industry forwards.

Think Sealless – WHAT is a Sealless Pump?

Essentially, sealless pumps are centrifugal pumps without packed glands or seals. Instead of a seal, there is a static containment shell or shroud, which forms a completely sealed liquid end or pressure boundary.

Prime mover energy is transmitted to the sealed liquid end by a bank of external magnets, which pass force through the containment shell to the inner magnets attached to the impeller shaft, meaning there is no risk of leaks or emissions.

Sealless v Sealed Pumps

It’s necessary to understand what a mechanical seal is to differentiate between the two types of pump. Mechanical seals are designed to maintain their sealing capability by leaking small amounts of fluid in order to keep the seal faces lubricated.

Mechanical seals are widely regarded as the weakest point in any pumping system. In fact, they account for 80% of all pump failures, with the remainder being leakage through static seals such as gaskets or O Rings and bearing failure.

Seals, like bearings, will ultimately wear and, as they wear, the seal faces lose their effectiveness and liquid loss through the seal increases. These fugitive emissions can be costly, resulting in lost time and money, as well as reduced worksite and environmental safety.

WHAT makes a HMD Kontro Sealless Pump different?

  • Welded metal containment shell to ASME VIII pressure vessel standards
  • Optional ZeroLoss® shell. To improve efficiency and reduce life cycle costs
  • Dynamically balanced rotating parts for smooth operation and longevity
  • Modular cartridge construction reducing maintenance time
  • Many common components reducing spare part inventory
  • Fully encapsulated outer magnet ring for protection and easy cleaning

WHY You Should Think Sealless And Choose A Sealless Pump?

It’s simple to see WHY you should choose a sealless pump over a sealed version. Among the reasons are the 5 S’s, relating to Savings, Safety, Skills, Standards and Solutions.

Sealless Savings: Cost savings can be made at every stage of your project from design, engineering, procurement, installation, documentation and commissioning. It’s easy to see how quicker completion times mean earlier plant utilisation. And those savings continue once your sealless pumps are up and running. With magnetic drive pumps, you will also benefit from less maintenance, longer mean time between failures (MTBF) and a more rapid return to operation, which all contributes to enhanced profitability and margins.

Sealless Safety: Health and safety is at the top of everyone’s list and it includes keeping all personnel safe who are involved in operations. Also it is essential to minimise the impact of manufacturing and other operations on both the local and wider environment from a legal and moral standpoint. Sealless pumps are completely self-contained with the containment shell providing a complete mechanical barrier, preventing leaks, escapes and emissions.

Sealless Skills: People are an expensive commodity and need to be employed to best effect. Sealless pumps save on staff costs and time due to the simplicity of the design, the ease of commissioning and the minimal maintenance requirement. This all means fewer people are needed and significantly less specialist skills are required leading to reduced training and employment costs.

Sealless Standards: All pumps have to conform to the relevant international standards including API, ASME, ANSI, and/or ISO. By installing sealless pumps from HMD Kontro, you know that compliance is guaranteed. The manufacturing and design of our pumps is also fully in accordance with ISO 9001. We ensure the stringent quality management and health & safety standards are met in order that your sealless pumps deliver consistent performance and to this end, we are continually identifying and implementing improvements.

Sealless Solutions: Sealless magnetic drive pumps are the solution to provide you with complete peace of mind. Pumps without seals do not need seal support systems, meaning there is no risk of seal failure and leaks and emissions are eliminated. Sealless pumps are kinder to the environment and safer for operators. Maintenance is considerably reduced with the mean time between failure (MTBF) for magnetic drive sealless pumps typically three times longer than for mechanically sealed pumps.

Ground breaking innovation and technical advances since 1947

Since we developed the first sealless magnetic drive pump in 1947, ground-breaking at that time in pump and fluid handling technology, we have continued to be at the forefront of innovation and technological development.
