(1)
Maximum temperature for continuous application due to EPDM gaskets and standard lobe rotor clearances. To consult for
higher temperatures.
(2)
The maximum viscosity allowed will depend on the nature of the liquid and the sliding speed of the seal faces.
Consult INOXPA should the viscosity be still greater.
Use special protection when the noise level in the operation area exceeds 85 dB(A).
