HCO

Mechanical seal centrifugal pumps

HCO

HCO pumps are mechanical seal centrifugal pumps with semi-open impeller made of thermoplastic materials (Polypropylene and PVDF) suitable to transfer acids and corrosive liquids also with solids.

The mechanical seal is manufactured by GemmeCotti and it is available in two different model: the seal of pumps size 95-10 is guaranteed by a special elastomeric lip seal, while all the other pump sizes from HCO 110 to HCO 170 are equipped with an internal PTFE bellows mechanical seal (sic/ceramic).

MAIN APPLICATIONS

Mechanical seal centrifugal pumps model HCO are suitable to pump acids and highly corrosive liquids used in chemical industries, biotechnology, pharmaceutical, photographic processing equipment, metal finishing machines, PCB printed circuit boards, petrochemical industries, textile industries, graphics, heat exchangers, water treatment plants, filter units, galvanic industry, food processing, sugar plants, military industries, dairies, packaging industries and many more.

These kind of pumps can easily handle acids without any problem of chemical corrosion such as for example: acetic acid, alcohol ethyl, ammonia, detergents, hydrochloric acid, hydrofluoric acid, phosphoric acid, sea water, sodium chloride, sodium hydroxide, sodium hypochlorite, sulfuric acid.
