Wave Spring Seal

FLOW-PROOF (FPW) series are single wave spring unbalanced/balanced Mechanical Seals designed for most
general applications. It is independent of direction of rotation major advantage of this seal is due to use of single
or double wave spring it is of compact design with reduced axial length, their compact design easy to install.
These seals can also be used in textile, petrochemicals, hi-pressure pump & dirty application as spring clogging
does not occur; torque transmission from retainer shell to seal ring is through drive pin. All parts are
interchangeable, one can convert this series by changing only the dynamic ring and the secondary seal, this
principle is ideal for stock rationalization, this seals are comfortable to use in wide range of application
