Features mechanical seal hrc-n
- Cartridge
- Balanced
- Independent of direction of rotation
- Stationary multiple springs
- Spring protection sleeve
- Variant for operation with pressureless quench available (HRC2000N)
- Dual seal with and without pumping screw (HRC3300NF, HRC3300N) available
Advantages mechanical seal hrc-n
- Insensitive to solids containing media. Solids content 40 % (single seal), 60 % (double seal)
- Springs protected from product and leakage
- Variant with short installation length to meet limited space conditions (HRC1100N)
- Dual seal remains closed in case of barrier pressure failure, self-closing at pressure reversal (HRC3300NF)
- Operation under vacuum without seat locking possible
- No damage of the shaft by dynamically loaded O-Ring
- Insensitive to shaft deflections due to stationary design
Operating range mechanical seal hrc-n
- Shaft diameter:
d10 = 30 … 60 mm (1.181″… 2.362″) - Pressure: p1 = 23 bar (334 PSI)
- Temperature:
t = -20 °C … +160 (200*) °C
(-4 °F … +320 (382*) °F) - Sliding velocity: vg = 20 m/s (66 ft)
- Axial movement: ±1.0 mm
* Due to shrinking
