Product Description

Product details
Features

• Single seal
• Balanced
• Independent of direction of rotation
• Stationary springs
• Dual seals in tandem as well as back-to-back arrangements (also in combination with H10 seal)

Advantages

• Safe operation (no fractures) because of seal face locking by square pin
• Spring unit averted from the product so no sticking and clogging of the springs
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design

Operating range
Shaft diameter:
d = 18 ... 100 mm (0.71" … 3.94")
Pressure: p1*) = 25 bar (363 PSI)
Temperature:
t = -40 °C ... +220 °C (-40 °F … 428 °F)
Sliding velocity: vg = 20 m/s (66 ft/s)
Axial movement: ±1.0 mm

* Additional seat locking is not needed in vacuum operation. For operation under vacuum it is necessary to arrange for quenching on the atmosphere side.
Materials
Seal face: Carbon graphite resin impregnated (B), Silicon carbide (Q1)
Seat: Silicon carbide (Q1)
Secondary seals: FKM (V), NBR (P), FFKM (K), PTFE (T)
Springs: Hastelloy® C-4 (M)
Metal parts: CrNiMo steel (G)
Recommended applications

• Water and waste water technology
• Refining technology

• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media

• Chemical standard pumps
• Sewage pumps
