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.

TECHNICAL DATA
* 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.
OPTIONAL
FLANGES
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.
BASEPLATES
GemmeCotti baseplates are suitable for pump completed with motor with B3/B5 configuration. They allow the correct positioning of the pump.
A1-13Y
We recommended the use of the dry-running protection device for all the applications where the constant presence of liquid in the pump is not always ensured.
