Why seal-less pumps can provide benefits over sealed pumps

The inherent irony that is at the root of many industrial manufacturing processes is this: oftentimes, “bad” things are needed to produce “good” things. Or, to be a little more specific, hazardous things are needed to manufacture useful things. Manufacturers who produce chemical-based compounds such as caustics, acids, solvents and polymers should be well aware of this dichotomy.
Hazardous substances like toluene, xylene and ethylene oxide – along with a host of hundreds of others – that can be harmful to humans and the environment if mishandled are nevertheless indispensable components that must be used in a large number of industries and end products.
A tip-of-the-iceberg list of such industries and products includes, but is hardly limited to, petrochemicals, paints and coatings, soap and detergents, biofuels, adhesives, pulp and paper, food processing, and herbicides and pesticides.
In addition to being widely used and potentially dangerous or hazardous if mishandled, many chemical compounds are also extremely expensive. If a leak were to occur during the handling or transfer of these products, large costs would be incurred by the operator...
