SANDPIPER 1 Lubricator - Manual

SERVICE AND OPERATING MANUAL
1” Filter/Regulator
1” Lubricator
WARNING
The polycarbonate plastic material used
to manufacture the plastic bowls and the
sight dome on lubricators may be
attacked by certain chemicals. DO NOT
use these units on systems with air
supplied by a compressor lubricated with
synthetic oils or oils containing
phosphate esters or chlorinated
hydrocarbons. These oils carry over into
the air lines and will chemically attack or
possibly rupture the bowl and lubricator
sight dome. DO NOT expose these units
to materials such as carbon tetrachloride,
trichlorethylene, acetone, paint thinner,
cleaning fluids, or other harmful materials.
These will cause the plastic to craze and/
or rupture. For use in environments where
any of these chemicals may be present,
consult the factory for approval prior to
installation.

A Note About Air Valve Lubrication
The SandPIPER pump’s pilot valve and
main air valve assemblies are designed
to operate WITHOUT lubrication. This is
the preferred mode of operation. There
may be instances of personal
preference, or poor quality air supplies
when lubrication of the compressed air
supply is required. The pump air system
will operate with properly lubricated
compressed air supplies.
It is important to remember to inspect
the sleeve and spool set routinely. It
should move back and forth freely. This
is most important when the air supply
is lubricated. If a lubricator is used, oil
accumulation will, over time, collect any
debris from the compressed air. This can
prevent the pump from operating
properly.

Filter/Regulator & Lubricator
INSTALLATION:
Before installing, blow out pipe line to remove scale and other foreign
matter. This unit has DRYSEAL pipe threads. Use pipe compound or tape sparingly to male
threads only. Install filter-regulator in pipe line so that air will flow in direction of arrow stamped
on body. Install as near as possible to equipment serviced. Filter-regulator must be installed
with bowl in a vertical position.
ADJUSTMENT:
To unlock adjustment, push knob fully down (in). Turn knob clockwise
to increase pressure and counter-clockwise to lower pressure. With relieving-type regulators,
the reduced pressure follows adjustment of the screw. To lock adjustment, simply pull knob
fully up. If tamperproof adjustment is required, remove knob completely.
MAINTENANCE - CLEANING:
To clean, it is not necessary to remove regulator
from line. To maintain maximum filtering efficiency and to avoid excessive pressure drop, the
filter must be kept clean. Turn drain valve clockwise to remove liquid accumulation before it
reaches level of lower baffle. A visible coating of dirt or condensate on filter element or
excessive pressure drop indicates cleaning is necessary. If the air supply is kept clean, the
regulator should provide long periods of uninterrupted service. Erratic operation or loss of
regulation is usually due to dirt in the disc area. To clean, shut off air line pressure and
disassemble the filter-regulator. When reassembling, make sure the disc stem fits into center
hole of piston assembly.
INSTALLATION:
Before installing, blow out pipe line to remove scale and other foreign
matter. This unit has DRYSEAL pipe threads. Use pipe compound or tape sparingly to male
threads only. Install lubricator with bowl vertical in pipe line so that air will flow in direction
indicated by arrow on lubricator body. Install as near as possible to equipment to be lubricated.
To assure trouble-free performance, a filter should be installed upstream from the lubricator. A
combination insert (part number 020-052-008) may be used to mount the lubricator directly to
the filter/regulator. Remove the insert pins and inserts from the filter/regulator discharge and
lubricator inlet. Install the combination insert between filter/regulator and lubricator. Be sure
o-rings are in place and lubricated. The combination insert should be seated firmly prior to
installation of pins.
LUBRICANT:
For average conditions, the use of a high quality SAE #10 (S.U.V. 150-
200 SEC @ 100°F/38°C) non-detergent oil is recommended.
NOTE: The oil and its container must be clean. Dirt will clog the lubricator, making shut-down
and cleaning necessary.
FILLING:
Lubricators can be filled while under pressure and without shutting down
equipment. Slowly remove either fill plug and fill to within ¼”/6.4mm of top of bowl using correct
oil.
OPERATION:
The dial set knob is factory set. When turned to zero (0) no oil is delivered
to the venturi for atomization and equipment is not being lubricated. Turn on the air to start flow
and set knob to obtain the desired drops per minute, visible through the sight glass. As a start,
one drop per minute is suggested, correct lubrication being a matter of experience and
demand. Clockwise rotation of knob decreases oil feed rate. To check lubrication, hold a
thumbnail or a mirror near the equipment exhaust. A heavy film indicates over-lubrication and
the drops per minute should be reduced by turning knob clockwise to a lower setting.
MAINTENANCE:
If both air and oil are kept clean and the oil level never allowed
below end of tube in the bowl, the lubricator should provide long periods of unattended service.
Cessation of oil dripping through the sight glass, regardless of knob adjustment is an indication
that cleaning is necessary.
CLEANING:
To clean, it is not necessary to remove lubricator from the line. Depressurize
and disassemble. In most instances cleaning is needed only in the oil metering area. Pull off the
adjusting knob and unscrew sight dome assembly, remove inner drip spout and clean with
household soap. METAL BOWLS WITH SIGHT GLASSES AND SIGHT DOME MUST BE
CLEANED WITH HOUSEHOLD SOAP ONLY.
WARNING
Clean metal bowl and sight glass only
with household soap. Do not use
denatured alcohol to clean.
