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?

It Can Take The Heat! The CS Sealless Pump For Heat Transfer in Hot Oil Systems

A Unique Sealless Pump for Heat Transfer in Hot Oil Systems

Isolating the pump from the heat source has usually been essential in a hot oil system.  However, thanks to its unique torque ring, our CS pump requires no cooling fluids or heat exchangers during operation.

The CS Sealless Pump is the perfect choice

The pump is totally self-venting and the magnetic coupling is immersed in the hot oil. Not only that, the torque ring design offers a built-in soft start for viscous liquids, and the energy created adds to the efficiency of the system.

Simple to operate and maintain, cost-effective to run and capable of operating up to 350°C / 660°F without cooling as standard (a 450°C/842°F option is available on request), this all makes the HMD Kontro CS sealless pump the ideal choice.

Benefits of the CS Pump

  • Ideal for heat transfer liquids
  • Sealless design provides total product containment
  • No product cooling required for temperatures up to 350°C / 660°F as standard
  • One fully confined Casing Gasket to eliminate ‘blowout’ risk
  • Built-in soft start feature, which is ideal for viscous start up

In addition, the torque ring drive positively contributes to the efficiency of the hot oil system and the CS can also be used in toxic, aggressive, hot, crystallising and high value processes.

Now with Longer MTBF for Increased Operational Efficiency

The recent upgrade of the outer magnet ring (OMR) on the CS range now offers significant additional advances in magnetic coupling robustness, leading to increased MTBF (mean time between failure), reduced downtime / increased uptime and increased operational efficiency.

The OMR upgrade maintains similar performance and maintains reliability

The retro-fittable OMR provides shielded magnets that retain the same level of performance and eliminate any potential for damage.  The new OMR has improved cyclic thermal duty whilst the identical coupling power produced means that the upgrade maintains similar performance to maintain reliability.

The encapsulated magnets on the OMR are made of samarium cobalt and have increased resistance in corrosive applications.  They also provide higher efficiency by reducing slip and improved reliability because no tie bolts are used in the retention of the magnets.

Download a copy of our recently updated guide to the Know How surrounding sealless pumps. They have always had significant benefits, especially thanks to the absolute absence of leaks or emissions. However, these are now coming further to the fore due to recent and more stringent environmental, health and safety requirements. For the Guide to Sealless Magnetic Drive Pumps click here.

Environment, Health and Safety (EHS)

In these days of increasing EHS concerns, and the resulting legislation and litigation, leakages of process product can cause significant problems. Damage can be caused not only to personnel and property onsite, but also to reputations, plus also the loss of production uptime and valuable productivity.

Choose the safe option – a sealless magnetic drive pump

Unlike pumps that include a mechanical seal, which is designed to leak a little for lubrication, but which could also fail, a sealless pump is the safe option. With a sealless pump, the product is completely contained at all times with no potential for leaks, no escapes to the atmosphere, no emissions, no health issues, no safety concerns and no environmental hazards. No How!

A virtual lack of maintenance and repair meaning less downtime

A further advantage of the sealless pump is the almost complete lack of maintenance and repair required. Not only does this reduce the work and requirement for routine and replacement parts, it also eliminates the associated downtime.

Sealless pumps are now an option on new applications

You may be surprised. The capabilities and operating parameters for sealless pumps may well now be much higher than you think. As a result, they are finding many new applications and are often being used on installations where traditional mechanical sealed pumps would be first considered.

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.
