1243Dx

A double cartridge seal with a “face to face” arrangement which allows operation with barrier fluids in high pressure conditions towards the working fluid (P1 + 2 ~ 3 kg/cm2).
The cartridge seal sleeve has grating that favours the barrier fluid movement. The barrier fluid input and output connections must be connected in accordance with the shaft rotation direction.

1243BA

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.

1243BB-6

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.

1243CI-4

Double cartridge seal with a “tandem” arrangement suitable for working with pressurised or non-pressurised barrier fluids. Recommended in applications in which a high level of safety is required.
Possibility of incorporating a pumping ring to reduce the temperature gradient between the mechanical seal contact surfaces.

1243CH

Double cartridge seal with a “tandem” arrangement sui- table for working with pressurised or non-pressurised barrier fluids.
The metal bellows design has a self-cleaning effect that prevents particles from building up inside it.
This model is recommended in extremely demanding applications: with high-viscosity fluids, sticky fluids, particle-laden fluids, fluids with few lubricating and/ or pollutant properties and in high temperature applications. Highly reliable cartridge.
