1648, 2648, and 3648 API 682 Type A Pusher Seals
Industrial applications in the processing of volatile organic
compounds (VOCs) and similar hazardous materials.
Lubricating liquids, aqueous solutions, chemicals, some acids,
and light hydrocarbons. Type 1648/2648/3648 seals evolved
from the successful, proven John Crane Type 48 design, the
preferred choice for safe, reliable, tandem and double seal
arrangements in petroleum services for more than 10 years.
These dependable, engineered mechanical seals were
developed specifically to attain M.A.C.T. compliance in light
hydrocarbons and other VOCs. Type 1648 single seals
typically control emissions to less than 200 ppm.
