SS-BT-PN:Burgmann BT-PN,John Crane Type 106 mechanical seal
Features:
Equivalent to Burgmann BT-PN,John Crane Type 106
Single and dual seals
Short axial installation length
Material approvals available
Operating range:
Shaft diameter: d1 = 8 … 30 mm
Pressure: p1* = 12 bar (170 PSI)
Temperature: t* = -20 °C … +120 °C (-4 °C … +248 °F)
Sliding velocity: vg = 10 m/s (33 ft/s)
*) Depending on medium, size and material
Materials:
Seal face: Carbon graphite resin impregnated (B), Carbon graphite solid (B3), Silicon carbide (Q1, Q6)
Seat: Steatite (X), Aluminium oxide (V, V1), Silicon carbide (Q1, Q6)
Elastomer: NBR (P), EPDM (E), FKM (V)
Metal parts: CrNiMo steel (G), CrNi steel (F)
Recommended applications:
Water and waste water technology
Building services industry
Food and beverage industry
Water and waste water
Beverages and food stuffs
Submersible motors up to 4 inches
Submersible pumps, back-to-back installation
Peripheral pumps for industrial applications
Domestic and garden pumps
Coffee machines
Water pumps
Advantages:
The small seal for increased pressure. The S-SBT-PN is a mechanical seal with a simple but effective design for mass-produced pumps. The special spring arrangement allows a short axial installation length. This advantage is combined with an increased working pressure capability and because the spring is free from torque transmission.
