Magnetic drive centrifugal pumps made in thermoplastic materials suitable to be used in a potentially explosive atmosphere classified ZONE 2 II3G

Anti-corrosion industrial pumps suitable for pumping acids and bases fluids and highly corrosive liquids

  • Materials available: PP / PVDF.
  • Flow up to 130 m3/h; Head up to 48 mlc.
  • Temperature: PP: max 70° C – PVDF: max 90°C.
  • Max viscosity: 200 cSt.
  • Pressure rating: NP 6 at 20°C.
  • Lip seal for pumps size 95-10; internal PTFE bellows mechanical seal for all the other sizes.
  • Suitable for high corrosive liquids containing solids in suspension (non-abrasive solids max. 5% – dimension max. 3 mm).

Centrifugal pumps series EM-CO with mechanical seal are made of thermoplastic materials (Polypropylene and PVDF) and are suitable for high corrosive liquids containing solids in suspension. The seal of pumps EM-CO size 95-10 is guaranteed by a special elastomeric lip seal, while all the other pump sizes (from size 110 to 170) are equipped with an internal PTFE bellows mechanical seal (sic/ceramic), which is manufactured by GemmeCotti.


* 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.

*For any information and quotation you can fill in the online form or send an email to info@gemmecotti.com. Our commercial office will select the pump suitable for your needs.



On request GemmeCotti provides DIN e ANSI flanges for thermoplastic pumps (cartella + free flanges) and welded DIN o ANSI  flanges for pumps in AISI 316.
