SANDPIPER 1/4 Lubricator - Manual

SERVICE AND OPERATING MANUAL
¼” Filter/Regulator
¼” 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.
Filter/Regulator
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 units in pipeline so that flow is with the arrows as indicated on faces of body.
Install as near as possible to equipment serviced.
MAINTENANCE:
To maintain maximum filtering efficiency and to avoid excessive
pressure drop, the filter must be kept clean. Bowl drainage is automatic in the Piston Drain
model, however, manual draining can also be done by removing the bowl. A visible coating of
dirt or condensate on the filter element surface or an excessive pressure drop is an indication
that cleaning is necessary.
FILTER CLEANING:
To clean, it is not necessary to remove filter from the line.
Disassembly is simple and does not require tools. Before disassembly, shut off air supply and
depressurize filter. Clean all parts except plastic bowl with alcohol and blow out filter body
before reassembly. Wash filter element in alcohol and blow out from the inside. Plastic bowls
must be cleaned with household soap only.
PISTON DRAIN OPERATION:
The Piston Drain mechanism is operated by the
pressure drop created as air flow is initiated or as the air line is depressurized. In order to drain
properly, there must be sufficient dynamic pressure drop to trigger the drain mechanism. The Piston
Drain will not function with minimal flow and pressure variations or on constant flow applications.
REDUCED PRESSURE ADJUSTMENT:
To adjust reduced pressure
setting, loosen lock screw in center of knob and turn knob clockwise to increase pressure
setting and counter-clockwise to lower setting. With relieving-type regulators the reduced
pressure follows adjustment of the screw.
REGULATOR CLEANING:
Erratic regulator operation or loss of regulation is
generally due to dirt in the disc area. To clean, shut off and depressurize air line and disassemble
the regulator. Refer to drawing on reverse as a guide to disassembly and subsequent
reassembly. Clean parts with household soap and blow out body with compressed air. When
reassembling, make sure the disk assembly is firmly in place and that the disc stem fits into
center hole of diaphragm assembly. Tighten cage slightly more than hand tight (to 50 inch/
pounds, or 5.65 Newton meters torque).

Lubricator
LUBRICANT:
For average conditions, the use of high quality SAE #10 (S.U.V. 150-200
SEC. @ 100°F/38°C) non-detergent oil is recommended.
FILLING:
Depressurize system and slowly remove the fill plug. Fill to within ¼”(.635cm)
of top of bowl using correct oil. For best results use a long spout oil can. Lubricators may also
be filled by depressurizing the system and removing the bowl. After filling, replace the bowl,
making sure it has been tightened before repressurizing the system.
ADJUSTMENT:
The adjustment knob is factory set, fully closed. When turned fully
clockwise, no oil is delivered to the venturi for atomization and equipment is not being lubricated.
To adjust oil drip rate, turn on the air, start flow and set knob to obtain the desired drip rate. Drip
rate is visible through the sight dome. As a start, one or two 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 thumbnail or a mirror near the equipment
exhaust. A heavy film indicates over-lubrication and the drip rate should be reduced by turning
knob to a lower setting.
LUBRICATOR MAINTENANCE & CLEANING:
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. When no oil drips through the sight dome,
regardless of knob adjustment, cleaning is necessary. 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 adjusting knob and unscrew sight dome assembly,
remove inner drip spout and clean with household soap. PLASTIC BOWLS AND SIGHT DOME
MUST BE CLEANED WITH HOUSEHOLD SOAP ONLY.
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.
