I.INSPECTION
If damageis discoveredupon ulpacking the equipment,an immediate requestshould be
forwarded to the delivering carrier to perform an inspection and proparea concealed-damagereport.
Concurrently, the nature and extent of damageshould be reported to Newport Scientific, Inc., giving
catalog and serial numbers, so that action may be initiated to replace damagedparts, or instructions
issuedfor the return of the apparafus.

PRINCIPLES
OF OPERATION
Theplungerof the compression
headis reciprocated
asin a pump. Oil from the
storagebulb is compressed
by the plunger,which in turn pulsesthe diaphragrn.The fluid to be
compressedis takenin and dischargedon the oppositesideof the diaphragmthroughthe check
valvesin theheadplateon the down andup strokeof the diaphragm.Oil is drawninto the chamber
beneaththe diaphragmby the suctioncreatedon theplungerbackstroke.Excessoil in the chamber
canflow back to the storagebulb during the fonvardplungerstrokethroughthe pressurelimiting
device. This built-in hydraulicdeviceis manuallyadjustableandensuresthat the dischargepressure
of the compressor
cannotexceeda presetlimit. Theplungerstrokeis presetso that undernormal
operatingconditions,oil will not flow throughthe pressurelimiting deviceunlessthe maximum
dischargepressureis exceeded.
PERFORMANCE CHARACTERISTICS AND SPECIFICATIONS
IV.
CHARACTERISTICS:
-
Contamination-freegas compression.
Parts in contact with gas are made of the following materials:
Upperheadplates,l7-4PH SS;Valves,302,304,316,17-4PHSS andNylon 101;
Diaphragms,302SS.Compressoris suitable for suction at constantor continually varying suction pressuresup to
the maximum permissible dischargepressure.
Compressionratios of up to 14-to-l are obtainablefor each stage.
Diaphragm life in excessof 500 hours of operation normally attained.
Absence of stuffing box permits leak-free operation.
Elastomerpacking provides a leak-free oil seal,long life and never needstightening.
Interchangeable check valves permit either continuous gas or intermittent liquid service.
Check valves can be easily removed for cleaning and replacement.
Floating hydraulic plunger ensuresminimum wear on packing.
SPECIFICATIONS: All compressorintake and dischargecheck valve openings (female) are for Yo

ADJUSTMENT OF PRESSURE LIMITING
DEVICE
NOTE: The PressureLimiting Device was presetby Newport Scientific and should never needreadjustment. This device was set to releaseoil back to the storagebulb when the dischargepressure
reachesll0% of the maximum pressurerating of the compressor. This setting was obtainedby
turning the setscrewat the top of the pressurelimiter until the desiredreleasepressurewas obtained.
The setscrewwas then held stationarywhile the outer stop nut was tightened down to the limiter body
to lock in the setting. As long as the stop nut is not turned relative to the setscrew,the setscrewcan
be tumed out and in for priming and still maintain the original factory setting.
If the stop nut has been turned relative to the setscrew,the following procedurecan be followed to
reproducethe original setting.
1.
Install pressuregaugesin the inlet & outlet lines of the compressorif not alreadypresent.
2.
Make sure system is primed and check valves are operating properly as per Section VI,

the following configurationis recommended.
CRANK STROKE ADJUSTMENT PROCEDURE
On Motor-Driven Compressors,the piston stroke length is presetby Newport Scientific and
must be re-adjustedif:
.
- The slide block clamping bolts work loose or are intentionally loosened.
- The head assembly or packing are changed.
NOTE: The pressurelimiter adjustrnentneed not be changedunlessthe original factory setting was
lost accordingto the last section on Adjustrnent of the PressureLimiting Device. If the pressure
limiter and the crank stroke both need adjustment,they must be performed simultaneouslyaccording
to No. 11 of this section.
For maximum compressoreffrciency, the volume of oil displaced is critical. This volume is
proportional to the length of the piston sffoke, and the adjustmentprocedureis the samefor all
compressorsand all piston sizes.-Refer to Section [V, Specifications.
