ROTEN SEALS TYPE 3 IN WIDIA/WIDIA/NBR
ROTATION: unidirectional right; available on request with left spring (to place an order for a seal with left-handed rotation, add SX after the code: e.g. 0101028SX; 5% increase on the list price) COUNTERFACE: with O-Ring MAX PRESSURE: 16 bar TEMPERATURE: -25°C +90°C USES: dirty liquids not acidic This type of mechanical seal is a valid alternative to the Roten type 2 Widia/Widia with the following advantages:
- containment of costs
- total interchangeability between the two types of seals
- use of solid tungsten carbide rings instead of welded rings
- resistance to abrasion as for Roten 2; resistance to corrosion as for Roten 3, inexistent in the Roten 2
- with addition of Viton gaskets, they can be used for fluids derived from petroleum or chemical products in general
O-ring in EPDM and VITON FPM for liquids that require it.
The distance *L is taken as with the seal in the working position (spring compressed).
