- Stationary and rotating contact surfaces on both product and atmospheric sides.
- O-rings, springs, set screws, sleeve, flange, setting clips, flat gasket, and drive ring.
The document provides a detailed dimensions chart for shafts ranging from 25 mm to 120 mm, with corresponding measurements in inches. Dimensions are subject to changes or modifications.
- Balanced and multispring design.
- Not dependent on rotation direction.
- Includes barrier fluid connections.
- Shaft diameter (d1): 25 to 120 mm.
- Pressure (p): 20 kg/cm².
- Velocity (v): 20 m/s.
- Temperature (t): -15 to +200°C, depending on secondary seal materials.
The operating limits are defined by the PV factor, which is determined by the sealing system characteristics and application specifics.
The double cartridge seal features a "back to back" arrangement, allowing operation with barrier fluids under excessive pressure conditions. It is recommended for applications involving toxic, contaminant, or potentially dangerous fluids where safety is crucial.
3/8" NPT connections are provided, with specific arrangements for 25, 28, and 30 mm shafts.

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
