Molub-Alloy 887
Detergent Oil
Description
Molub-Alloy 887 Detergent Oil was developed for use in non-flooded sliding
vane rotary compressors but is also effectively used in circulating systems such
as for paper machine dryer sections.
Molub-Alloy 887 Detergent Oil is processed from specially selected naphthenic
base oils of low carbon content and high flash point, combining specialized
refining and manufacturing processes which effectively retard the formation of
varnish and hard carbon deposits. These same properties will also retard
formation of sludge in intercoolers and aftercoolers.
Metallic solids of suitable grade are treated to increase their natural positive
affinity to metal surfaces and are completely dispersed to assure effectiveness
during the lubricant's full working life.
Rust and oxidation inhibiting characteristics are maximized to afford effective rust
protection and long life of the oil.
Foaming is controlled by the use of special compounds and inhibitors
Applications
Molub-Alloy 887 Detergent Oil was developed for use in non-flooded sliding
vane rotary compressors where problems from deposits have been experienced.
It also provides outstanding service as a crankcase and cylinder lubricant in
reciprocating compressors.
Application methods of Molub-Alloy 887 Detergent Oil are by typical force feed
lubricators as provided by the manufacturer for cylinder and bearing lubrication.
Where compressed air discharge temperatures are below 163ºC, Molub-Alloy
887-40 is recommended.
Advantages
Reduced friction, most evident under boundary conditions, is directly attributed
to the presence of specially compounded lubricating solids. This benefit is most
pronounced where frequent start-up, slow speeds, and high and unexpected
loads are encountered.
Product DataSubstantial increase in the working life of both parts and lubricant is provided by
a protective layer of Molub-Alloy solids. This can result in an increased load
bearing area, which reduces unit pressures, operating temperatures and wear.
Realistic energy savings are possible through a reduction in peak power
demand during cold start-up.
Molub-Alloy 887 contains an ashless detergent developed to retard the
formation of varnish and carbon. The detergent in the oils prevents the vane
slots from becoming fouled, and also keeps the compressor cylinder, check
valve area, discharge line and aftercooler carbon and varnish free.
Overall savings are derived from the above and result from less labour and
downtime, smoother, more efficient operation with longer parts life, and
extended lubrication cycles.
Notes
Lubrication recommendations contained in this Product Data Sheet do not
apply to refrigeration compressors.
