DOUBLE CARTRIDGE SEALS COMPONENTS: 1 p Stationan/ contact surface product side 2p Rotating contact surface product side 1 a Rotating contact surface atmospheric side 2a Stationary/ contact surface atmospheric side 3 O-rings 4 Springs 5 Set screws 6 Sleeve 7 Flange 8 Setting clips 9 Flat gasket 10 Drive ring CHARACTERISTICS: • Balanced. • Multispring. • Not dependent on the rotation direction. • Barrier fluid connections. OPERATING LIMITS: d,= 25 - 120 mm p= 20 kg/cm! v= 20 m/s t= -15- +200°C (*) (*) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: A double cartridge seal with a “back to back” arrangement which permits operation with barrier fluids in excessive pressure conditions with respect to the working fluid (P1 + 1.5 ~ 2 kg/cm2). For this reason it is advisable to install it in applications with toxic, contaminant or potentially dangerous fluids in where safety is an important factor. CONNECTIONS: 3/8" NPT. For 25, 28 and 30 mm shafts the connections are at opposite sides of the flange. DIMENSIONS CHART Dimensions in mm Dimensions in inches Dimensions subject to changes or modifications. SAFE INDUSTRY
