HCO – Mechanical seal centrifugal pumps
HCO – Mechanical seal centrifugal pumps
Mechanical seal centrifugal pumps HCO series, fitted with a mechanical sealing system, are manufactured in thermoplastic materials such as Polypropylene (PP) and PVDF. They are specifically designed for handling highly aggressive and corrosive liquids, even when solid particles are present in suspension.
Several mechanical seal configurations are available, depending on the pump size and operating requirements.
The sealing arrangement differs according to the pump model:
-
HCO 95-10: supplied with a special elastomeric lip seal.
-
HCO 110–170: equipped with an internal PTFE bellows mechanical seal, offered in two material combinations:
-
Standard version: SiC / Ceramic
-
Optional on request: Graphite / Ceramic
-
-
HCO 180–200: available with two alternative sealing solutions:
-
Single mechanical seal in SiC / Ceramic
-
Double back-to-back mechanical seal, with various material options depending on the pumped chemical
-
The double mechanical seal configuration requires an external flushing system.
