We have manufactured only sealless pumps since 1947 and so the design is specific and not a modified mechanically sealed pump. They are made to a very robust design and engineered to last and to perform.
The containment shell of an HMD Kontro Sealless Pump is either of welded construction to ASME VIII pressure vessel standards with a thicker and guaranteed wall thickness or is the latest composite ZeroLoss® shell. The latter resulting in improved efficiency and reduced equipment life cycle costs.
Other magnetic drive pumps usually have hydroformed / deep-drawn shells, which are much thinner and weaker than the HMD Kontro design. Rotating parts in our pumps are dynamically balanced ensuring smooth, quiet operation and longevity.
The magnets are fully encapsulated on the outer magnet ring, ensuring their protection from being chipped during pump re- assembly and against corrosion from the pumped liquid in the unlikely event of containment shell breach. It also means that the component can be easily cleaned in usual workshop conditions.
HMD Kontro pumps utilise a modular cartridge, which can reduce maintenance time considerably. This method of construction means that there are many common components for each product line throughout the HMD Kontro portfolio, reducing the need for a large stock of spare parts in a multiple pump installation.
Sealless pumps don’t leak, meaning that they can help reduce process inefficiencies, maximise output and minimise the risks posed to your process environment by hazardous and volatile materials.
