How do I select a centrifuge?

SELECTION ADVICE

Of the numerous engines used in various applications and industries Spin-Clean has already identified the proper centrifuge(s) to be used and developed installation bulletin that indicate supply and return points.  Ask your Spin-Clean Agent or contact Customer Service for a copy.  If we do not have an installation bulletin for your engine follow the steps below.

ENGINE SIZE

Usually the size of the engine affects the amount of contaminants.  It is therefore necessary to select a centrifuge (or number of centrifuges) with an adequate dirt-holding capacity to accommodate the volume of dirt likely to be generated during an oil change interval.  When seeking factory assistance on an installation be prepared to provide.....

OIL PUMP OUTLET

Since a bypass centrifuge of this type is taking oil from the engine pressure lubrication system, it is necessary to estimate the quantity of oil that is surplus to the oil requirements of the engine and is flowing back to the sump via the pressure relief valve.  The surplus would usually be approximately 30% of the total lube oil pump output under normal running conditions.  The objective would be to use about one third of this, i.e. approximately 10% of the oil pump total output to drive the centrifuge.  By relating this 10% to the appropriate oil flow charts of each centrifuge, it will be possible to select the optimum centrifuge relative to the surplus oil flow available.  There are very few large engines with lube oil pumps that have relatively little surplus lube oil capacity.  In these cases, a separate pump and motor are necessary to supply the centrifuge.

OIL SYSTEM CAPACITY

The volume of oil in the system may be used to determine the type and number of centrifuges to be fitted.  A centrifuge should be specified to ensure that the total crankcase oil capacity passes through the centrifuge(s), no less than four times in an hour.

OTHER CONSIDERATIONS

The optimum oil inlet pressure for a centrifuge ranges from 60 to 80 psi, but units can be operated at a maximum of 100 psi or a minimum of 40 psi.  Lower pressure reduces centrifugal force efficiency.

NOTE: The dirt holding capacity of the turbine bowl in our centrifuge is approximately 10 times the dirt capacity of a conventional filter.If an engine user experiences large dirt build-ups in the centrifuge(s) applied due to special fuel conditions or unusual airborne contaminants, or has a limited full-flow filter element time-to- service interval, an increase in size or numbers of centrifuges should be considered.  In this case, consult FPE for assistance.
