100 GSDN Mechanical Seals for Pumps Pusher Seals

(1)Features
• Stationary springs
• Rotating seat
• Double seal
• Balanced
• Cartridge unit
• Standard version with V-grooves, U-grooves optional (independent of direction of rotation)
• Gas-lubricated, gas-buffered
• Internally pressurized
• Does not open in the event of buffer pressure failure, self closing at pressure reversal

(2)Advantages
• Contact-free operation
• No friction on the seal faces, no heat generated at the seal or in the medium
• No additional complex components to dissipate frictional heat
• Maximum environmental protection and maximum efficiency

(3)Operating range (see note on page 1)
Shaft diameter: d1 = 30 ... 100 mm (1.18" ... 3.94")
Pressure:
p1 = 13 bar (189 PSI), p3 = 16 bar (232 PSI)
with V-grooves (uni-directional)
p1 = 9 bar (131 PSI), p3 = 12 bar (174 PSI)
with U-grooves (bi-directional)

Differential pressure (p3 - p1) = min. 3 bar (44 PSI)
