The reliability of a submersible Flygt pump or mixer will never be better than the reliability of its seal system. Unlike dry installed equipment, any fluid that manages to leak through the seals will accumulate in the pump or mixer and cannot be drained in operation. In a longer perspective, a seal leakage will always cause numerous problems. Exceptional demands are therefore made on every Flygt Plug-in seal to achieve high reliability, trouble free operation and long service intervals

Double mechanical seal with Single Unit Assembly

Seal faces remain protected from contamination

The preassembly in clean environment secure that seal faces remain protected as they are in contact already from the assembly line. Thanks to this, the risk for contaminated seal faces during mounting is therefore eliminated. Mounting of single seals or relapped seals increase the risk for contaminated seal surfaces causing leakage and/or excessive wear.

Springs are protected from corrosive pump media and clogging

The springs are located in the barrier fluid side of the seals, completely shielded from the pump media to ensure trouble-free operation.

Inner seal and outer seal are replaced at the same time, securing overall sealing reliability

The outer seal and inner seal can not be replaced or renovated separately. As the lifetime of an inner seal is impossible to estimate, the inner seal is therefore automatically replaced whenever the outer seal is replaced due to wear. In addition, remounting of separate seal rings that have been running for some time may cause excessive leakage due to the fact that seal ring faces “wear in” matching grooves. If removed and installed again, the grooves will not match each other.

Thorough testing secure air tightness

All Flygt Plug-in seals are thoroughly pre-tested for tightness before delivery. The seal units are mounted in a seal cavity, similar to the ones in the products. A differential pressure is applied when the inner and outer seals are tested independently, for air tightness while rotating.

No special service tools required.

The Plug-in seal is easy and quick to mount in the pump. All double seal components are supplied and assembled in a tandem arrangement incorporated into one single unit assembly.
