Chemicals and emulsions
Plasticizers, surfactants, emulsions, additives, Belli Meccanica produces a wide range of pumps for every application in the chemical sector also according to the Atex zone 1 directive.
The selection of the right materials and an adequate sealing system is essential in order to obtain high reliability. Thanks to our experience we are able to supply pumps entirely in stainless steel and with sealing systems specifically designed for the specific application. If the pumped liquid does not present particular difficulties, more simple and cheaper seals are used as in the case of Series C pumps. When the product to be processed has high criticalities deriving from its nature (for example, tendency to catalyze or solidify) or its toxicity, more advanced sealing systems are supplied (double, flushed, pressurized seals) like in the case of the L Series pumps.
In case total absence of leaks is required, the MAG series magnetic drive pumps are widely used with excellent performance and reliability results.
