Regulations and Approvals

Make sure all equipment is rated and approved for the

environment in which it is used. Any approvals obtained for

Nordson equipment will be voided if instructions for installation,

operation, and service are not followed.

Personal Safety

To prevent injury follow these instructions.

SDo not operate or service equipment unless you are

qualified.

SDo not operate equipment unless safety guards, doors, or

covers are intact and automatic interlocks are operating

properly. Do not bypass or disarm any safety devices.

SKeep clear of moving equipment. Before adjusting or

servicing moving equipment, shut off the power supply and

wait until the equipment comes to a complete stop. Lock

out power and secure the equipment to prevent unexpected

movement.

SRelieve (bleed off) hydraulic and pneumatic pressure before

adjusting or servicing pressurized systems or components.

Disconnect, lock out, and tag switches before servicing

electrical equipment.

SWhile operating manual spray guns, make sure you are

grounded. Wear electrically conductive gloves or a

grounding strap connected to the gun handle or other true

earth ground. Do not wear or carry metallic objects such as

jewelry or tools.

SIf you receive even a slight electrical shock, shut down all

electrical or electrostatic equipment immediately. Do not

restart the equipment until the problem has been identified

and corrected.

SObtain and read Material Safety Data Sheets (MSDS) for all

materials used. Follow the manufacturer’s instructions for

safe handling and use of materials, and use recommended

personal protection devices.

SMake sure the spray area is adequately ventilated.

STo prevent injury, be aware of less-obvious dangers in the

workplace that often cannot be completely eliminated, such

as hot surfaces, sharp edges, energized electrical circuits,

and moving parts that cannot be enclosed or otherwise

guarded for practical reasons.

High-Pressure Fluids

High-pressure fluids, unless they are safely contained, are

extremely hazardous. Always relieve fluid pressure before

adjusting or servicing high pressure equipment. A jet of

high-pressure fluid can cut like a knife and cause serious bodily

injury, amputation, or death. Fluids penetrating the skin can also

cause toxic poisoning.

If you suffer a fluid injection injury, seek medical care

immediately. If possible, provide a copy of the MSDS for the

injected fluid to the health care provider.

The National Spray Equipment Manufacturers Association has

created a wallet card that you should carry when you are

operating high-pressure spray equipment. These cards are

supplied with your equipment. The following is the text of this

card:

WARNING: Any injury caused by high pressure

liquid can be serious. If you are injured or even

suspect an injury:

SGo to an emergency room immediately.

STell the doctor that you suspect an injection injury.

SShow him this card

STell him what kind of material you were spraying

MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO

PHYSICIAN

Injection in the skin is a serious traumatic injury. It is important

to treat the injury surgically as soon as possible. Do not delay

treatment to research toxicity. Toxicity is a concern with some

exotic coatings injected directly into the bloodstream.

Consultation with a plastic surgeon or a reconstructive hand

surgeon may be advisable.

The seriousness of the wound depends on where the injury is on

the body, whether the substance hit something on its way in and

deflected causing more damage, and many other variables

including skin microflora residing in the paint or gun which are

blasted into the wound. If the injected paint contains acrylic

latex and titanium dioxide that damage the tissue’s resistance to

infection, bacterial growth will flourish. The treatment that

doctors recommend for an injection injury to the hand includes

immediate decompression of the closed vascular compartments

of the hand to release the underlying tissue distended by the

injected paint, judicious wound debridement, and immediate

antibiotic treatment.

Fire Safety

To avoid a fire or explosion, follow these instructions.

SGround all conductive equipment. Use only grounded air

and fluid hoses. Check equipment and workpiece

grounding devices regularly. Resistance to ground must not

exceed one megohm.

SShut down all equipment immediately if you notice static

sparking or arcing. Do not restart the equipment until the

cause has been identified and corrected.

SDo not smoke, weld, grind, or use open flames where

flammable materials are being used or stored.

SDo not heat materials to temperatures above those

recommended by the manufacturer. Make sure heat

monitoring and limiting devices are working properly.

SProvide adequate ventilation to prevent dangerous

concentrations of volatile particles or vapors. Refer to local

codes or your material MSDS for guidance.

SDo not disconnect live electrical circuits when working with

flammable materials. Shut off power at a disconnect switch

first to prevent sparking.

SKnow where emergency stop buttons, shutoff valves, and

fire extinguishers are located. If a fire starts in a spray

booth, immediately shut off the spray system and exhaust

fans.

SShut off electrostatic power and ground the charging system

before adjusting, cleaning, or repairing electrostatic

equipment.

SClean, maintain, test, and repair equipment according to the

instructions in your equipment documentation.

SUse only replacement parts that are designed for use with

original equipment. Contact your Nordson representative

for parts information and advice.

Halogenated Hydrocarbon Solvent Hazards

Do not use halogenated hydrocarbon solvents in a pressurized

system that contains aluminum components. Under pressure,

these solvents can react with aluminum and explode, causing

injury, death, or property damage. Halogenated hydrocarbon

solvents contain one or more of the following elements:

Element Symbol Prefix

Fluorine F “Fluoro-”

Chlorine Cl “Chloro-”

Bromine Br “Bromo-”

Iodine I “Iodo-”

Check your material MSDS or contact your material supplier for

more information. If you must use halogenated hydrocarbon

solvents, contact your Nordson representative for information

about compatible Nordson components.

Action in the Event of a Malfunction

If a system or any equipment in a system malfunctions, shut off

the system immediately and perform the following steps:

SDisconnect and lock out system electrical power. Close

hydraulic and pneumatic shutoff valves and relieve

servicing according to local codes.

Pro-Meter Gear Metering Pump 3

Part 303808E−03

E 2008 Nordson Corporation

Description

See Figure 1.

The Pro-Meter gear metering pump is designed to deliver

and meter pressurized materials.

A bulk unloader pump supplies material to the inlet

manifold (7) of the high pressure, positive-displacement

gear pump (5). The gear pump is powered by a

motor (10) and is driven by a speed reducer (4). The

speed reducer uses the motor input to increase the

torque and decrease the speed. A tachometer ring (3)

monitors motor speed; material flow can be determined

from the motor speed.

The gear pump package is used with a system controller.

The system controller may vary depending on the

application. Adjustments at the system controller

enclosure can be used to change the motor speed and

affect the desired pump flow rate. For information on the

system controller, refer to the appropriate system

controller manual.

Components
