Safety Information

IMPORTANT

Read the safety warnings and instructions in this manual before pump installation and start-up. Failure to comply with the recommendations stated in this manual could damage the pump and void factory warranty.

When the pump is used for materials that tend to settle out or solidify, the pump should be flushed after each use to prevent damage. In freezing temperatures the pump should be completely drained between uses.

CAUTION

Before pump operation, inspect all fasteners for loosening caused by gasket creep. Retighten loose fasteners to prevent leakage. Follow recommended torques stated in this manual.

Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet radiation can damage these parts and negatively affect material properties. Do not expose to UV light for extended periods of time.

WARNING

When used for toxic or aggressive fluids, the pump should always be flushed clean prior to disassembly.

Before maintenance or repair, shut off the compressed gas line, bleed the pressure, and disconnect the gas line from the pump. Be certain that approved eye protection and protective clothing are worn at all times. Failure to follow these recommendations may result in serious injury or death.

Gasborne particles and loud noise hazards. Wear eye and ear protection.

In the event of diaphragm rupture, pumped material may enter the gas end of the pump, and be discharged into the atmosphere. If pumping a product that is hazardous or toxic, the gas exhaust must be piped to an appropriate area for safe containment.

Take action to prevent static sparking. Fire or explosion can result, especially when handling flammable liquids. The pump, piping, valves, containers and other miscellaneous equipment must be properly grounded.

This pump is pressurized internally with gas pressure during operation. Make certain that all fasteners are in good condition and are reinstalled properly during reassembly.

Use safe practices when lifting

Grounding the Pump

To be fully groundable, the pumps must be ATEX Compliant. Refer to the nomenclature page for ordering information.

Optional 8 foot long (244 centimeters) Ground Strap is available for easy ground connection.

To reduce the risk of static electrical sparking, this pump must be grounded. Check the local electrical code for detailed grounding instruction and the type of equipment required.

Refer to nomenclature page for ordering information.

WARNING

Take action to prevent static sparking. Fire or explosion can result, especially when handling flammable liquids. The pump, piping, valves, containers or other miscellaneous equipment must be grounded.

Materials

Material Profile:	Operating
CAUTION! Operating temperature limitations are as follows:	Temperatures:
CAUTION! Operating temperature limitations are as follows:	Max.	Min.
FKM: (Fluorocarbon) Shows good resistance to a wide range	350°F	-40°F
of oils and solvents; especially all aliphatic, aromatic and	177°C	-40°C
halogenated hydrocarbons, acids, animal and vegetable oils.
Hot water or hot aqueous solutions (over 70°F(21°C)) will
attack FKM.
Nitrile: General purpose, oil-resistant. Shows good solvent, oil,	190°F	-10°F
water and hydraulic fluid resistance. Should not be used with	88°C	-23°C
highly polar solvents like acetone and MEK, ozone, chlorinated
hydrocarbons and nitro hydrocarbons.
Virgin PTFE: (PFA/TFE) Chemically inert, virtually impervious.	220°F	-35°F
Very few chemicals are known to chemically react with PTFE;	104°C	-37°C
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.

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.

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.
