MODEL G20 Metallic 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.

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

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

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:

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.

Exhaust Gas: The exhausted natural gas must be vented to a low pressure safe location in accordance with

local re safety and environmental codes, or in the absence of local codes, an industry or nationally recognized

code having jurisdiction over the specic installations, and/or CAN/CGA B149, Installation Codes

These pump models are designed to pump the following uids:

Crude Oil, Salt Water, Drilling Mud, Condensate, Lubrication Oils,

Glycol, Caustic Liquids, and Acids.”
