MODEL SB1/SB25 Performance Curve

Performance based on the following: elastomer fitted pump, flooded suction,

water at ambient conditions. The use of other materials and varying hydraulic

conditions may result in deviations in excess of 5%.

Materials

Material Prole:

Operating

Temperatures:

Max. Min.

Conductive Acetal: Tough, impact resistant, ductile. Good

abrasion resistance and low friction surface. Generally inert, with

good chemical resistance except for strong acids and oxidizing

agents.

190°F

88°C

-20°F

-29°C

EPDM: Shows very good water and chemical resistance. Has

poor resistance to oils and solvents, but is fair in ketones and

alcohols.

280°F

138°C

-40°F

-40°C

FKM: (Fluorocarbon) Shows good resistance to a wide range

of oils and solvents; especially all aliphatic, aromatic and

halogenated hydrocarbons, acids, animal and vegetable oils.

Hot water or hot aqueous solutions (over 70°F(21°C)) will

attack FKM.

350°F

177°C

-40°F

-40°C

Hytrel®: Good on acids, bases, amines and glycols at room

temperatures only.

220°F

104°C

-20°F

-29°C

Neoprene: All purpose. Resistance to vegetable oils. Generally

not affected by moderate chemicals, fats, greases and many

oils and solvents. Generally attacked by strong oxidizing acids,

ketones, esters and nitro hydrocarbons and chlorinated aromatic

hydrocarbons.

200°F

93°C

-10°F

-23°C

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.

190°F

88°C

-10°F

-23°C

Nylon: 6/6 High strength and toughness over a wide

temperature range. Moderate to good resistance to fuels, oils

and chemicals.

180°F

82°C

32°F

0°C

Polypropylene: A thermoplastic polymer. Moderate tensile

and ex strength. Resists stong acids and alkali. Attacked by

chlorine, fuming nitric acid and other strong oxidizing agents.

180°F

82°C

32°F

0°C

PVDF: (Polyvinylidene Fluoride) A durable uoroplastic with

excellent chemical resistance. Excellent for UV applications.

High tensile strength and impact resistance.

250°F

121°C

0°F

-18°C

Santoprene®: Injection molded thermoplastic elastomer with

no fabric layer. Long mechanical ex life. Excellent abrasion

resistance.

275°F

135°C

-40°F

-40°C

UHMW PE: A thermoplastic that is highly resistant to a broad

range of chemicals. Exhibits outstanding abrasion and impact

resistance, along with environmental stress-cracking resistance.

180°F

82°C

-35°F

-37°C

Urethane: Shows good resistance to abrasives. Has poor

resistance to most solvents and oils.

150°F

66°C

32°F

0°C

Virgin PTFE: (PFA/TFE) Chemically inert, virtually impervious.

Very few chemicals are known to chemically react with PTFE;

molten alkali metals, turbulent liquid or gaseous uorine and

a few uoro-chemicals such as chlorine triuoride or oxygen

diuoride which readily liberate free uorine at elevated

temperatures.

220°F

104°C

-35°F

-37°C

Maximum and Minimum Temperatures are the limits for which these materials can be operated.

Temperatures coupled with pressure affect the longevity of diaphragm pump components.

Maximum life should not be expected at the extreme limits of the temperature ranges.

Metals:

Alloy C: Equal to ASTM494 CW-12M-1 specication for nickel and nickel alloy.

Stainless Steel: Equal to or exceeding ASTM specication A743 CF-8M 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.

For specic applications, always consult the Chemical Resistance Chart.

CAUTION! Operating temperature limitations are as follows:

Ambient temperature range: -20°C to +40°C

Process temperature range: -20°C to +80°C for models rated as category 1 equipment

-20°C to +100°C for models rated as category 2 equipment

In addition, the ambient temperature range and the process temperature range do not exceed the operating temperature range of the applied non-metallic parts as listed in the manuals of the pumps.
