Made from yttrium stabilized zirconia ceramic, it is highly durable, wear-resistant, and capable of withstanding extreme temperatures and pressures. Ceramic plunger nozzle core holes usually need to meet very strict precision requirements to ensure the efficiency and stability of the injector. Unipretec can provide zirconia ceramic metering plungers with a machining accuracy of +/-0.005mm and a mirror surface finish.
Zirconia ceramic plunger used in the diesel fuel injector pump for diesel engine
Zirconia ceramic plungers are widely used in diesel engine fuel injectors M11/ISM11/QSM11, conventional models are injector metering plunger ceramic plunger valve 34117111; high pressure oil pump 3973228; fuel pump ceramic plunger C4088593; ISLE diesel engine fuel pump ceramic plunger core 4088593; fuel pump CCR1600; ISLE fuel pump ceramic plunger ceramic valve core 3330992, air compressor air pump 4318214/4059825, etc.
Ceramic plunger for fuel diesel injection engine advantage:
1.Higher strength than metal materials
2.High hardness, able to resist wear and scratch, suitable for use in high wear environments
3.Excellent chemical corrosion resistance, able to maintain stability in harsh chemical media
4.High hardness, smooth surface finish
5.High dimensional accuracy
6.Perform stably under thermal changes
