DOUBLE CARTRIDGE SEALS LDC22-F SECTORS: COMPONENTS: 1p Rotating contact surface product side 2p Stationary contact surface product side 1a Stationary contact surface atmospheric side 2a Rotating 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 - 100 mm p= 28 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: Double cartridge seal with a "face to face” arrangement which permits operation with barrier fluids (pressurised or not pressurised) and the flushing of the surfaces on the product side. The protected multispring system in the rotating part absorbs the transmission of misalignments, knocks, oscillations and vibrations of the shaft on the contact surfaces and extends the useful life in unfavourable operating conditions. Suitable for applications with highly viscous, sticky, catalytic fluids which have very few lubricant properties or are highly abrasive. CONNECTIONS: From 25 mm to 60 mm: 1/4” NPT. From 63 mm to 110 mm: 3/8” NPT. Dimensions subject to changes or modifications.
