Alternative to:
for Burgmann BT-AR, AES B01, Roten 37B/L5, Flowserve 118, Latty T750, VULCAN 18
Mechanical seal for large-series cold water pumps,
produced in millions of units per year. The BT-AR owes its
success to the wide range of application, the short axial
length (this allows for more economic pump construction
and saves material), and the best quality/price ratio.
The elasticity of the bellows design enables a more robust
operation.
The BT-AR can also be used as a multiple seal in tandem
or back-to-back arrangement when the product media
cannot ensure lubrication, or when sealing media with
a higher solids content. Installation proposals can be
provided upon request.
