301 Single Spring Mechanical Shaft Size Eagle Burgmann BTAR Replacement

Operations Conditions:

Structure: Single End

Pressure: Low Pressure Mechanical Seals

Speed: General Speed Mechanical Seal

Temperature: General Temperature Mechanical Seal

Performance: Wear

Standard: DIN24250

Model NO.: Type 301, BT-AR

Balance: Unbalanced

Specification: Inner Diameter: 6 mm to 60 mm

Temperature:-20ºC to +120ºC

Pressure:≤0.6MPa

Speed:≤10m/s

Materials:

Structural Features: single end, unbalanced, independent direction of rotation, rubber bellow transmission. This component has a compact structure and it is easy to install. The bellow and the spring provide pressure compensation to the seal faces. The rubber bellow design prevents possible radial run-out so the floatabilitiy of the rotary ring is increased.

Stationary Ring: Ceramic(Alumina),Silicon Carbide Reaction Bonded

Rotary Ring: Q5,Resin Impregnated Carbon Graphite(Furan), Silicon Carbide Reaction Bonded

Secondary Seal: Fluorocarbon Rubber(FKM), Nitrile(NBR), Ethylene Propylene(EPDM)

Spring and Metal Parts: Stainless Steel

Applications: Clean Water
