Categoria:

Centrifugal pumps series HCO with mechanical seal are made of thermoplastic materials (Polypropylene and PVDF) and are suitable for highly corrosive liquids containing solids in suspension. Different types of mechanical seals are available to suit various sizes and applications.

The sealing system varies according to the pump size:

  • HCO 95-10: equipped with a special elastomeric lip seal.
  • HCO 110 – 170: equipped with an internal PTFE bellows mechanical seal. Two materials are available:
  1. Standard: SiC / Ceramic
  2. Available upon request: Graphite / Ceramic
  • HCO 180 – 200: available with two sealing options:
  1. Single mechanical seal: material SiC / Ceramic 
  2. Double mechanical seal back to back: different materials available according to the pumped liquid. 

The double mechanical seal version requires an external flushing system. 

TECHNICAL DATA

HCO - MECHANICAL SEAL CENTRIFUGAL PUMPS

* The head and flow of the pump refer to the performance with water at room temperature. Should liquids at high temperatures and with high viscosity and density be pumped the performance has to be calculated accordingly. The electric motor should be selected on the basis of the viscosity and the specific weight given by the customer.

STRONG POINTS OF HCO PUMPS

hco-pompe-centrifughe-tenuta-meccanica

MANUFACTURING MATERIALS

HCO pumps are made of thermoplastic materials PP or PVDF and they are compatible with most acids and basic liquids, chemicals and other dangerous fluids.

INJECTION MOULDING

The plastic parts of HCO pumps are made by GemmePlast, a company belonging to the GemmeCotti  group, which is specialized in the injection molding for plastic materials.
This allow for a careful quality check of the raw materials and the complete control of the entire molding process.

RELIABILITY

Unlike many centrifugal pumps on the market the pump head of GemmeCotti pumps is fixed to the bracket with 8 bolts. This feature guarantees a firm fastening of the pump head to the bracket and avoid the casing deformation under pressure.

 

REDUCTION OF MAINTENANCE COSTS

The design of the mechanical lip and bellows seals of the HCO pumps are designed and manufactured by GemmeCotti, which allows considerable savings in terms of maintenance costs.

MECHANICAL SEAL

The seal in mechanical seal pumps is composed by a static ring and a rotating ring placed on the pump shaft which is directly coupled to the motor shaft. The two surfaces sliding together need to be lubricated and the seal lubricant is the liquid itself that is being pumped.

UPN baseplates

METALLIC UPN BASEPLATES

GemmeCotti supplies UPN baseplates as an optional accessory for chemical horizontal pumps, both magnetic drive and mechanical seal types.
