Mechanical seals with conical rotating spring

NT-2 Mechanical seal with conical rotating spring

DIN 24960

 

 

The more compact version allows it to be used in pumps for heating, sludge and fecal pumps, as well as in food industry pumps.

The sealing face combination is selected in accordance with the applied substance and operating conditions.

The secondary seal is completed by means of O-rings. The quality is in accordance with the type of substance.

The other seal elements are nickel chrome steel.
