Product Description

Product Description

(1)Features    
•Cartridge
•Balanced
•Independent of direction of rotation
•Stationary multiple springs
•Variant with short installation length (HRC1100N)
•Spring protection sleeve
•Variant for operation with pressureless quench available (HRC2000N)
•Dual seal with and without pumping screw (HRC3000NF, HRC3000N) available

(2) Advantages
•Insensitive to solids containing media. Solids content 40 % (single seal) and 60 % (double seal)
• Springs are protected from product and leakage
• Broad field of application due to modular system 
• Optimal for standardization purposes
• Variant with short installation length to meet limited space conditions (HRC1100N)
• Seal remains closed in case of barrier pressure failure, self-closing at pressure reversal (HR3000NF)
• Operation under vacuum without seat locking possible
• Pumping screw for increased circulation available
• No damage of the shaft by dynamically loaded O-Ring
• Insensitive to shaft deflections due to stationary design
• Straightforward installation due to pre-assembled unit
• Installation errors are excluded
• No damage caused by dirt entered during assembly

(3)Operating range (see note on page 1)
Shaft diameter: d10 = 30 ... 60 mm (1.181" ... 2.362")
Pressure: p1 = 25 bar (360 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

(4)Materials

(8)Product variants
HRC1100N
Same design as HRC1000N, but with a shorter cover 
plate featuring integral spring and drive pin pockets (Item 
no. 8). No adapter (Item no. 9). Shaft sleeve (Item no. 2) 
uncoated. Differs from modular system!

HRC2000N
Single seal with pressureless quench for cooling, featuring 
guide sleeve (Item no. 12) baffle (Item no. 17), adapter 
(Item no. 15) and lip seal (Item no. 13) on the atmosphere 
side. Option: Throttle ring for sealing steam quench on the 
atmosphere side.

HRC3000NF
With pumping screw dependent on direction of rotation. 
Dual seal which remains closed in case of barrier pressure 
failure and closes automatically in the event of pressure 
reversal. With guide sleeve (item no. 12) and balanced 
mechanical seal on the atmosphere side (item nos. 13.1, 
13.2). Operation as single seal with quench is possible.
