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 Profile: 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 fluid 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 fluorine and
a few fluoro-chemicals such as chlorine trifluoride or oxygen
difluoride which readily liberate free fluorine 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 specification 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 specific 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 fire safety and environmental codes, or in the absence of local codes, an industry or nationally recognized
code having jurisdiction over the specific installations, and/or CAN/CGA B149, Installation Codes
These pump models are designed to pump the following fluids:
Crude Oil, Salt Water, Drilling Mud, Condensate, Lubrication Oils,
Glycol, Caustic Liquids, and Acids.”
