THINK SEALLESS - Why you should choose a sealless pump?

Sealless pumps are not only intrinsically safe they are also easier to maintain, have fewer working parts, no potential leak paths and no support systems to design, install and maintain. Servicing and maintenance is simple, and the life cost is significantly lower than that of a mechanical sealed pump. Read More


THINK SEALLESS - How sealless pumps save you money

Magnetic drive pumps are almost 'fit and forget' requiring minimal maintenance and monitoring. Thanks to modular construction and the ability to dismantle HMD Kontro sealless pumps without special tools, servicing of the pumps on-site is simple and straightforward. Common components means less spare parts stock and inventory for reduced operational costs. Read More

THINK SEALLESS - What is a sealless pump?

Sealless pumps are essentially conventional centrifugal pumps without packed glands or seals. The seal is replaced by a static containment shell or shroud to form a completely sealed liquid end or pressure boundary. External magnets on the impeller shafts transmit prime mover energy to magnets in the sealed liquid end, and so there is no potential for leaks or emissions. Read More 

Sealless Technology
