This bulletin deals exclusively with Viking Lid-Ease®
Basket-Type Strainers. When ordering parts be sure to give
complete part name, serial number and model number (cast
on body below serialized nameplate). The basket mesh size
is stamped on the basket handle and the o-ring construction
can be identified with a Viking color code (listed under O-Ring
Information).
Use of basket strainers can avoid costly failures and increase
the life of the equipment. Proper use of strainer can minimize
down time. A definition for strainers is “a coarse filter”.
Strainers are typically intended to trap larger foreign objects
DANGER !
Before opening any Viking product (Strainer,
pumping chamber, reservoir, relief valve
adjusting screw cap etc.) be sure:
1. That any pressure in the strainer or pumping
chamber has been completely vented
through suction or discharge lines or other
appropriate openings or connections.
2. That the driving means (motor, turbine,
engine, etc.) has been “Locked Out” or
made non-operational so that it cannot
be started while maintenance is being
preformed.
3. That you know what liquid the strainer
has been handling and the necessary
precautions to safely handle the liquid.
Obtain a Material Safety Data Sheet (MSDS)
for the liquid to be sure these precautions
are understood.
Failure to follow above listed precautionary
measures may result in serious injury or
death.
Viking does not recommend using Lid-Ease Strainers for the
following applications:
1. Fluids having vapor pressure higher than one atmosphere,
either at room temperature or operating temperature.
2. Straining of particles finer than 70 microns (50Х250 Mesh
available through 4”).
3. Temperatures below -40 ºF or above +400 ºF.
4. High system pressure applications (See Table A, Page 2).
5. High basket differential pressure (See Table A).
6. Aluminium strainer handling 1,1,1-trichloroethane,
methylene chloride or halogenated hydrocarbon solvents.
Determine and exercise necessary precautions before
removing the lid, involving fluids which are:
-
POISONOUS OR TOXIC
- FLAMMABLE
- HARMFUL TO FACE OR HANDS
- HOT (Liquids containing boiling water (+212º F at sea
level) can produce steam; extra care to properly vent
strainer must be exercised).
- ENTRAINED WITH AIR (Trapped, pressurized air under
lid can lift the lid suddenly and violently if the lid is rotated.
Be the sure system is completely vented)
DO NOT ATTEMPT TO VENT THE SYSTEM BY TURNING
THE LID.

such as rags, weld beads or bolts. Filters are intended to
capture very small particles.
Lid sealing is accomplished with one o-ring, therefore
proper application of o-ring is essential. The o-ring must be
acceptable for the temperature limits of the system as well
as compatible with the fluid being strained. Misapplication
may result in o-ring swell, (making lid removal difficult) or
premature o-ring failure, causing strainer leakage.
