Cylinder liners with zirconia ceramics sleeve
Wear hardness and thermal resistivity have no match in comparison to any other materials of the sleeves. Moreover, the use of such sleeves allows to increase the service life of the pump piston by half, in comparison with the standard chrome-plated sleeve.
All liners have a stop ring to prevent the sleeve from slipping during use. Hardness — RC91-95. Service life is more than 4000 hours.
