Installation and wear control
Advantages
Reduced repair and downtime: 2 x 2 pre-assembled design speeds up and simplifies installation installation because pump does not have to be disassembled.
Long service life: precise pre-alignment because of pre-assembled segments. Stationary springs which are protected from the product prevent clogging.
Greater flexibility during installation: no modification necessary because the seal is located outside of the stuffing box.
Shaft protection: uniform torque transmission via clamping ring prevents damage caused by set screws.
Dependable operation: mechanical decoupling of clamping ring (torque transmission) avoids distortion of the seat.
Simple monitoring of the seal during operation because of mechanical wear indicator on the seal face.
Low leakage: elimination of secondary seals eliminates leakage paths between split components.
High tolerance to shaft deflections ensured by stationary design and elastic seat mounting (gasket).
