Operating Range
Shaft diameter:d1 = 50 … 150 mm
Pressure: p1 = 12 bar
Temperature:t = -20 ... +130 °C ,(above 80 °C flush is recommended)
Sliding velocity: vg = 10 m/s
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.
