Air-operated diaphragm pumps offer a wide range of
benets not available in any other type of pump. However,
in some applications, pulsations in the discharge ow may
be undesirable. Pulsation can be virtually eliminated by
installing a Warren Rupp Tranquilizer®.
At initial and subsequent start-ups . . . air cushion is
quickly established by liquid pressure pushing diaphragm
upward, permitting entrance of air into air chamber, until
the balancing air cushion causes the diaphragm to center
at its mid-stroke normal operating position.
During normal continuous operation thereafter . . .
the diaphragm always exes at its mid-range position
to absorb discharge pulsations against the adjoining air
cushion already established.
In event of change in pumped liquid pressure . . .
the air cushion pressure is automatically increased or
decreased as required to compensate for the change . .
. always maintaining constant volume of air cushion, and
the diaphragm always operating at its mid-position.
When liquid ow stops and liquid pressure is released
. . . the air in air chamber is also exhausted to atmosphere.
Tranquilizer
• Automatically maintains a constant volume of air cushion
for most effective surge suppression, regardless of pump
pressure.
• Automatically self-charging and self-venting to maintain
most efcient air cushion pressure . . . no more precharge
pressure calculations or guesswork, no manual
pressurizing, no periodic pressure checking.
• Air cushion separated from product by exible diaphragm
. . . prevents product aeration.
• External visual indication provides constant evidence of
performance.
• Simple to install. Attention-free.

MATERIALS
NITRILE: General purpose, oil-resistant. Shows good solvent, oil, water and hydraulic uid resistance. Should not be used
with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
NEOPRENE: All purpose. Resistant to vegetable oils. Generally not affected by moderate chemicals, fats, greases and
many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters, nitro hydrocarbons and chlorinated
aromatic hydrocarbons.
HYTREL®: Good on acids, bases, amines, and glycols at room temperature.
VIRGIN PTFE: Chemically inert, virtually impervious. Very few chemicals are know to chemically react with Teon®,
molten alkali metals, turbulent liquid or gases, uorine and a few uoro-chemicals such as chlorine triuoride or oxygen
diuoride which readily liberate free uorine at elevated temperatures.
FKM: Shows good resistance to a wide range of oils and solvents; especially all alipphatic, aromatic and halogenated
hydrocarbons, acids, animal and vegetables oils. Hot water or hot aqueous solutions (over 70
EPDM: Shows very good water and chemical resistance. Has poor resistance to oil and solvents, but is fair in ketones and
alcohols.

STAINLESS STEEL: CF-8M equal to or exceeding ASTM specication A743 for corrosion resistant iron chromium, iron chromium nickel, and nickel
based alloy castings for general applications. Commonly referred to as 316 Stainless Steel in the pump industry.
ALLOY C: CW-12MW equal to or exceeding ASTM A494 specication for nickel and nickel alloy castings.
For specic applications, always consult the Warren Rupp "Chemical Resistance Chart".
