HCO – Mechanical seal centrifugal pumps

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).
