SAFETY PRECAUTIONS

Export Information

Chemical Reaction Disclaimer

Unpacking & Inspection

U.S. Export Administration Regulations, pursuant to ECCN 2B350, prohibit the export or re-export to certain enumerated

countries of air operated double diaphragm pumps in which all wetted materials are constructed from fluoropolymers without

first apply-ing for and obtaining a license from the U.S. Bureau of Industry and Security(BIS). This affects all sera airPUMP

pumps constructed from PVDF with PTFE balls and diaphragms. Please

The user must exercise primary responsibility in selecting the product’s materials of construction which are compatible with the

fluid(s) that come(s) in contact with the product. The user may consult a manufacturer’s representative/distributor agent to seek

a recommendation of the product’s material of construction that offers the optimum available chemical compatibility.

However neither manufacturer nor agent shall be liable for product damage or failure, injuries, or any other damage or loss

arising out of a reaction, interaction or any chemical effect that occurs between the materials of the product’s construction and

fluids that come into contact with the product’s components.

Unpack the pump and examine for any signs of shipping damage.

If damage is detected, save the packaging and notify the carrier immediately.

To install the pump, follow the installation instructions provided.

WARNING

sera airPUMPs maximum temperature limits are based upon the material’s mechanical stress only. Maximum temperature is

ap-plication dependent. Consult a chemical resistance guide or the chemical manufacturer for chemical compatibility and

temperature limits.

WARNING

Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals. Always wear pro-

tec-tive clothing, eye protection and follow standard safety procedures when handling corrosive or personally harmful

materials. Proper procedures should be followed for draining and decontaminating the pump before disassembly and

inspection of the pump. There may be small quantities of chemicals present during inspection.

EXPLOSION HAZARD

sera airPUMP with standard materials of construction should not be used with halogenated hydrocarbons. Halogenated

hydrocarbon solvents can cause explosion when used with aluminum components in a closed (pressurized) system. sera

airPUMPs with standard materials of construction contain aluminum components and will be affected by halogenated

hydrocarbon solvents.

1-1-1 Trichloroethane and Methylene Chloride are the most common halogenated hydrocarbons. However, other haloge-

nated hydrocarbon solvents are suspect if used either as part of paint or adhesive formulation, or for clean-up flushing.

For applications that may involve halogenated hydrocarbons, contact sera to discuss the availability of alternative pump

materials of construction.

WARNING

Hot surfaces. sera airPUMPs are capable of handling liquids with temperatures as high as 104ºC (220ºF).

This may cause the outer areas of the pump to become hot as well and could cause burns.

WARNING

For polypropylene or PVDF pumps do not exceed 6.9 bar (100 psig) air supply and 8.3 bar (120 psig) for

aluminum and stainless steel.

WARNING

If a diaphragm rupture occurs, material being pumped may be forced out of the air exhaust. Proper care should be taken,

always wear protective clothing, eye protection & follow standard safety procedures.

WARNING

When pumping hazardous liquids, or operating the pump in an enclosed room, it is important to pipe the exhaust air to a

safe area.

WARNING

Pump exhaust may be loud and contain particles. Wear appropriate ear and eye protection. In the event of a diaphragm

rupture material can be forced out of the air exhaust muffler. If product is hazardous or toxic, pipe exhaust to appropriate

safe area.

CAUTION

Before attaching air supply to pump to make sure all airline debris is clear. It is recommended to use a

minimum 5µ (micron) air filter before the air valve.

CAUTION

Do not over-tighten the air inlet fitting or muffler. Too much torque could damage the air valve or muffler plate.

CAUTION

If pump is used with materials that tend to solidify or settle, the pump should be flushed after each use to prevent damage.

CAUTION

Use only genuine sera replacement parts to assure compatibility and longest service life.

CAUTION

Check the temperature limits for all wetted components when choosing pump materials. See table below.

CAUTION

Before maintenance or repair, close the compressed air line supply valve, bleed the pressure and disconnect air line from

the pump. Discharge line may also be pressurized. Any pressure must be relieved prior to servicing. Remove suction /

discharge lines & drain the pump.

INSTALLATION / START UP

Installation and Start up

Install the pump in a vertical position or it may not prime properly. Pump should be located as close to the product being

pumped as possible. Suction line length should be as short as possible and limit the number of fittings. Suction line di-ameter

should not be reduced smaller than the suction diameter of the pump. When using rigid pipe run short sections of flexible hose

or flexible connections between the pump & piping. Secure the pump to a suitable surface.

Air Supply

Connect the pump air inlet to an air supply with sufficient capacity to achieve desired performance. A pressure regulating

valve should be installed to insure air supply pressure does not exceed recommended limits.

Fasteners

Re-torque all fasteners before operation. Creep of housing and gasket materials may cause fasteners to loosen. Re-torque all

fasteners to the torque specifications listed on the exploded view drawing in this manual.

Air Inlet & Priming

Pump will start to operate as soon as the shut-off valve is opened. It is recommended to open the shut-off valve slowly at first.

Once the pump primes; the shut-off valve can be opened additionally to increase the pump’s flow. If the pump is oper-ating

but not pumping any liquid see the troubleshooting section for tips & suggestions.

Accessories

Surge suppressors, spill stops & filter regulators are available and should be used with sera airPUMP.

Air Valve Lubrication

No lubrication is required for the air distribution system.
