Theory of Operation
Theory of Operation
Use
The 8900 Proportioner is used with two component materials where one or both components is high viscosity. This is typically found in the sealant and adhesive industry, where special requirements for loading and pumping necessitate the use of the 8900 proportioning system.
Major Components
The major components of the 8900 Proportioner system include the:
• Component A or major volume metering cylinder
• Component B or minor volume metering cylinder
• Component A or major volume feed supply
• Component B or minor volume feed supply
Ratio Proportioning
The A and B cylinders are positive displacement metering cylinders. Positive displacement cylinders displace a defined volume of fluid for a given stroke length.
On fixed ratio units, the volumetric ratio is the ratio of the area of the component A displacement cylinder to the area of the component B displacement cylinder. At a 1:1 ratio, the displacement cylinders are the same size. On higher ratio units the component A cylinder is usually the larger of the two. The ratio of the components is the difference in effective area between the cylinders.
On variable ratio units, the component B cylinder has an adjustable stroke length. The component A cylinder has a fixed stroke length. By setting the stroke adjustment to different points on the connecting linkage, you can change the stroke length of the B cylinder, which changes the mix ratio. You can calculate the material mix ratio from the ratio of the cylinder displacement volume.
Note that the mix ratio of the 8900 Proportioner is achieved by volumetric ratio of component A to component B and not by weight. These two ratios are often different depending on material properties.
System Components and
Operation Overview
Feed Systems - Feed Pumps
Load the Feed Pumps and Proportioner
The A and B feed pumps/cylinders must completely fill
(prime) on both strokes to ensure accurate material displacement.
With high viscosity materials, it is difficult for material to flow into the pump. Individual feed pumps are used to supply these materials under pressure to the 8900 Proportioner. When air is trapped in the feed system due to improper loading, a condition called cavitation occurs.
If cavitation occurs, part of the downstroke will be used to fill the vacuum before any material is actually displaced. Since the total stroke length is used to calculate mix ratio, this may result in an off-ratio condition.
To prevent cavitation with higher viscosity materials, both cylinders are pressure fed. The A pump is pressurized by a pneumatic ram supply unit applying a downward force on a 55-gallon plate fitted into the drum. A shovel action pump fluid inlet further aids in pump priming. Component B is delivered to the B pump by pressure fed 5- or 55-gallon supply modules, depending on the volumetric ratio of the material.
Pneumatic ram assisted feed pumps may not be required for lower viscosity materials.
Feed Systems - Alternative Feed Supplies
Header or other feed systems may be used to supply A and B materials to the 8900 Proportioner. Generally these feed systems are provided by others and are not addressed in this manual. This manual applies only to the Graco Configured 8900 Proportioner system.
309790N
Theory of Operation
Pump Fluids to the Mixer
Fluid is pumped through the proportioner to a mix chamber or to a 2-component dispense gun, where component A and component B are first introduced before being mixed with a static mixer.
A fluid injector nozzle/check valve injects component B into component A at the mix chamber. When enough pressure builds up, the check valve opens and component B flows into the mix chamber. This means that during flow conditions with two positive displacement cylinders linked together, the pressures at the mix point are equal.
Any pressure differences noted on the gauges while running, reflect differences in the pressure lost by each fluid getting from the gauge to the mix point. These pressure drops are caused by hoses and fittings in conjunction with material viscosity.
Mix the Fluids
Both components leave the mix chamber and enter a static mixer where they are mixed to a homogeneous blend. The mixer consists of a series of left and right-hand spiral elements. This is true for both mix chamber and 2-component mix gun.
When the components are pumped through the mixer, they are progressively divided and recombined. Static mixers used on the 8900 Proportioner system include the tri-core mixer, flexible hose mixer, or disposable mixer.
Ratio Checks
On the variable ratio model, a ratio check station option verifies the volumetric mix ratio of the two components.
It is located at the outlet blocks. With all outbound fluid valves closed, each component flows through individual ball valves opened by a common handle into containers.
Volumetric mix ratio can be calculated from the weight of each component or by direct measurement. Ratio checks are performed with the back pressures set to actual operating pressures to simulate the normal back pressures created by the mix chamber and gun.
Dispense Valve
An extrusion flow gun is commonly used as the application device. It has a final or clean up mixer installed in the handle. Various extrusion nozzles are available for caulking or sealing applications.
Some 8900 Proportioners use a 2K disposable mixer
element dispense valve instead of the flow gun.
The 8900 Proportioner can be used in automatic assembly lines with the addition of a logic interface.

Ground
WARNING
The system must be properly grounded. Read warnings, page 5. Follow the instructions below.
Pump: use the ground wire and clamp (supplied). There are two styles of ground connections on pump air motors.
If you have the ground screw (a) shown in F IG . 4
(King air motor only), order part no. 222011 ground wire, ring terminal, and clamp assembly (b). To install
222011, remove the ground screw (a) and insert it through the eye of ring terminal (c), then tighten ground
screw back into air motor as shown in F IG . 4. Connect
the other end of the wire to a true earth ground.
c a b
Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of your air and fluid hoses. If the total resistance to ground exceeds 29 megohms, replace the hose immediately.
Air compressor: follow manufacturer’s recommendations.
Spray gun/dispense valve: ground through connection to a properly grounded fluid hose and pump.
Fluid supply container: follow your local code.
Substrate: follow your local code.
Solvent pails used when flushing: follow your local code. Use only conductive, metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold a metal part of the gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
F IG . 4: Ground Screw (King air motors only)
If you have the ground screw (d) shown in F IG . 5,
loosen the grounding lug locknut (g) and washer (f).
Insert one end of the ground wire (e) into the slot in lug
(d) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order 237569 ground wire and clamp assembly.

Flush
WARNING
Read warnings, pages 4-5. Follow Ground instructions, page 12.
• The equipment was tested with light, soluble oil.
Flush the system before loading material to avoid contamination.
• Flush at the lowest pressure possible and check connectors for leaks.
To flush the system:
1.
On the ram-mounted component A supply units, you must remove the drum ram plate to immerse the A pump in a solvent pail. To remove the plate: a.
Disconnect the blow-off air line from the ram plate.
b.
Disconnect the tie rod nuts from the ram cross beam.
c.
Remove seal plates between the pump and ram.
d.
Loosen ram tie rods from plate and remove plate.
e.
If a pail ram is used with the component B supply, remove the pail plate by loosening the 2 set screws.
f.
Position the solvent pail so the pump inlet is in the solvent.
2.
Flush the system and all hoses by very slowly opening the motor control valves until 30 psi (207 kPa,
2.1 bar) is shown on the component A outlet pressure gauge.
Flush for 1-2 minutes, then close the motor control valves.
CAUTION
To avoid damaging the pump, open the motor control valves very slowly to prevent a pump runaway condition.
It is normal for the air valve to exhaust air when it is partially open.
3.
Check connectors for leaks and tighten them if necessary.
4.
Remove the solvent pail(s) from the pump inlets.
5.
Operate the pump(s) at low pressure to remove excess solvent.
6.
Reinstall the drum or pail ram plates.

Set the Ratio (variable ratio models only)
Adjust ratio
The ratio of this unit is produced partially by the difference in the area of the metering cylinders and partially by the position of the adjustable fulcrum point in the Unibar linkage assembly. With the fulcrum point in the center, each meter cylinder strokes 3 in. (10.16 cm). In the center position, the dispense ratio is the same as the meter cylinder ratio.
The linkage is adjustable depending on the location of the fulcrum point. The linkage must be adjusted for each material application so the combined linkage and meter cylinder ratio equals the desired material mix ratio by volume. The ratio may be checked by weight, but the machine meters by volume and that ratio must be known before proceeding.
The initial linkage adjustment point can be calculated by
inserting known values into the formula on page 35. The
result is the distance in inches from the center of the fulcrum point to the center of the component B meter cylinder. For convenience, measure the distance between the grease fitting on the top of the fulcrum and the center of the component B cylinder meter rod.

Adjust the Flow Rate
The dispensing flow rate for the system is controlled by the material pressure of component A and component
B.The air pressure on pump A determines the flow rate from the material outlet. Perform the steps on page
page 24 to set an initial flow rate. When the setup is
complete, adjust flow to the correct rate.
The diagram in F IG . 22 shows the inlet and outlet of the meter cylinders in relation to the direction of rod movement. The material pressure gauges will represent either inlet or outlet pressure, depending on the direction of the rod. Inlet and outlet pressures are critical to establishing meter flow rates and balanced pressures.

Adjust Ratio on Variable Ratio Machine
The ratio of this unit is determined partially by the difference in the area of the metering cylinders and partially by the position of the adjustable fulcrum point in the Unibar linkage assembly. With the fulcrum in the center,
(next to stop at left of center), each meter cylinder strokes 3 in. In this center position, the dispense ratio is the same as the meter cylinder ratio. The ratio is adjustable from 1:1 to 20:1 depending on the location of the fulcrum point and cylinder size. There are three machines to accommodate these ratio ranges: 1:1-4:1,
2:1-8:1, and 5:1 to 20:1. The linkage must be adjusted for each material application so that the combination linkage and meter cylinder ratio equals the desired material mix ratio by volume. The ratio is checked by weight, but the machine meters by volume. Weight ratios must be known before proceeding. If weight ratios are not known, they can be calculated using the specific gravity and known volumetric ratio of each component.
The initial linkage adjustment point can be calculated by inserting known values into the following formula. The resulting value is the distance in inches from the center of the fulcrum point to the center of the component B meter cylinder. Measure the distance from the grease fitting on top of the fulcrum to the center of the component B cylinder meter rod. For reference, see the output
charts on pages 15 through 17.
Ratio Adjustment Calculation Example:
DR = Required mix ratio by desired volume (X:1)
PR = Selected cylinder ratio (1:1, 2:1, 5:1)
LR = Linkage ratio
LD = Linkage distance (component B cylinder centerline to fulcrum center divided by LR+1)
DR
PR
= LR
Cylinder ratio 1:1-4:1 machine use PR = 1
Cylinder ratio 2:1-8:1 machine use PR = 2
Cylinder ratio 5:1-20:1 machine use PR = 5)
Example:
• Desired volumetric mix ratio (DR) = 10:1
• Measured distance from grease fitting on top of the fulcrum to the center of the component B cylinder meter rod = 14.85 in.

2 + 1 or LD = 4.95 in.
Verify the Ratio
1.
Relieve pressure. See Pressure Relief Procedure on page 27.
2.
Remove gun and place a waste container under the component A and component B hoses.
3.
Open air valve to turn on unit.
4.
Activate the unit and using a collection container of known weight, collect a cup of component A and a proportionate amount of component B.
5.
Weigh each component carefully and subtract the weight of the container.
6.
Convert the manufacturer’s ratio to parts component
B per 100 parts Component A, by weight (2:1 =
100:50).
7.
Divide component B weight by component A weight.
8.
Multiply the result of step 7 by 100. The product is
the number of parts of component B the machine dispenses per 100 parts of Component A.
9.
Compare ratio obtained to ratio desired. Always make several ratio checks to ensure accuracy at final setup. Any air in the system will cause inaccurate ratio checks. If ratio checks are not consistent, review setup procedure.
10. If the ratio is incorrect, loosen fulcrum screw (A) and turn the ratio adjustment screw/nut (B) clockwise to decrease and counterclockwise to increase the amount of component B.
11. If the ratio is correct, tighten the fulcrum nut and reattach hoses (7) to the dispensing gun.

General Ratio Check Procedure
Checking the ratio allows the user to take samples of the metered material to ensure the equipment is operating properly.
Steps 4 and 5 are applicable only to mix manifold
models.
4.
Open the coupled ball valves (push up).
5.
Ensure that the component A purge ball valve is closed.
6.
Place a material waste container under the gun outlet and open the dispense gun.
7.
Dispense material until well mixed material is being dispensed.
8.
The system is now ready to operate.
Daily Shut-down/Purge Procedures
Component A Purge
1.
Close the coupled ball valves (push down).
2.
Open the component A purge ball valve.
3.
Hold the dispense gun over a material waste container.
4.
Hold the dispense gun open until only component A is evident.
5.
Close the component A purge ball valve.
6.
Close the main air valve located under the meter base plate to remove air pressure from the meter.
The unit meters by volume but it is more convenient to check the ratio by weight. You must know the ratio by weight or the specific gravity of the materials to convert volumetric ratio to weight ratio.
1.
Remove the hoses from the dispense gun. Take a material sample from the outlet of these hoses.
2.
Open the air ball valves (push up) and collect a large material sample (approximately 1 pint of component A) in separate containers of known weight.
Material flowing from each hose provides a sample for ratio check. When sample is collected, turn off air supply ball valve.
3.
Weigh the component A and component B samples and subtract the weight of the collection containers.
4.
Convert the material manufacturer’s ratio to “parts component B per 100 parts component A by weight.” For example, a 2:1 ratio (component A: component B) becomes 100:50.
5.
Divide component B sample weight by component A sample weight.
6.
Multiply the result of previous step by 100. The product is the parts component B dispensed by the machine per 100 parts component A by weight.
7.
Compare the weight ratio obtained to the desired weight ratio. Repeat to obtain several successful ratio checks.
8.
Put new mix elements in the gun and reconnect the hoses to the gun.

• Manufacture’s specified weight ratio = 4:1 or 100:25.
• Weight of component A in ratio check is 245 grams.
• Weight of component B in ratio check is 61.2 grams.
• 61.2 divided by 245 equals .2497 (61.2 / 245 = .2497).
Three ratio checks are recommended to ensure accuracy at final setup. The presence of any air (visible or not visible) in the material or system will cause inaccurate ratio checks. If the ratio check cannot be made with repetitive accuracy, review air bleed procedures.
Some materials contain substantial amounts of entrained air due to manufacturing, transportation, system setup, or drum change. Air must be removed by de-gassing, recirculation, or self removal over time, before accurate metering can be accomplished.

8900 Proportioner Operating
Pressures
There are four fluid pressure gauges on a typical 8900
Proportioner system. They are mounted on:
• Component A inlet block
• Component B inlet block
• Component A outlet block
• Component B outlet block
What the fluid gauges tell you
Inlet Gauge
The pump A and pump B inlet pressure gauge shows whether there is sufficient material supply to reliably feed each metering pump during its intake stroke.These double- acting pumps dispense and load fluid on both strokes.
The pump A and pump B supply air pressure should be set high enough to maintain reliable pump feed pressures but no higher than necessary. If gauge pressure is not consistently steady, increase fluid pressure.
Outlet Gauge
The pump A and pump B outlet gauge displays one of two conditions, stalled and running.
• Stalled: With the pump air valve on and the gun closed, the gauge will show full stall pressure. This pressure is the fluid to air pressure ratio of the pump assembly, times the air pressure from the main regulator, minus the friction loss of the motor and pump assembly.
The fluid to air pressure ratio changes with different motors, different supply pumps, and different ratio settings.
• Running: When running, the gauge reads the flow-induced pressure drop between the gauge and the gun outlet. The motor power is used up by the time the fluid exits the gun. The pressure drop is a measure of friction loss caused by hoses, the 8900
Proportioner, fittings, mixers, and gun.
The difference in the gauge reading between the stall condition and running is the amount of dynamic friction loss from the pump assembly, plus the flow-induced pressure drop from the pump lower to the pressure gauge.
Viscosity, temperature, flow rate, and gun setup can affect the amount of gauge drop when the trigger is pulled. On a typical manual gun system, the gauge drops 100-400 psi (0.7-2.8 MPa, 7-28 bar).
Component B Pump Outlet Gauge
The component B pump gauge shows line pressure, but the component B outlet pressure is generated primarily as a reaction to component A pressure at the mix chamber.
For materials running at greater than 1:1 ratio, component B cannot open the check (injector) valve until its pressure equals the component A pressure at the check valve. Hoses and injector restriction are chosen to naturally balance the pressure drop while running and match the component B pressure in the line when stalled.
Changeovers
When the pumps change direction there is a momentary change in gauges. In general, the gauges will drop
5-15%, then return. However, many factors affect the actual fluctuation, such as pump selection, fluid characteristics, flow rate, temperature, and length of hoses.
Check valves near the pump outlets isolate the hoses to let them serve as momentary surge chambers. This is why flow from the gun is smooth during changeover.
Abnormal Readings
Since so many factors affect gauge readings, it is important to know what is normal. Note how your gauges read when the machine is setup and running a good mix with no soft spots. What are the stall pressures and what are the running pressures for a given inbound air pressure?
How much drop is there on changeover?
If something goes wrong, a change on the gauges can indicate what the problem is. Note those changes and work through the troubleshooting guide, beginning on
36 309790N
Troubleshooting
Air Supply Troubleshooting Chart
Problem Cause Solution
Abnormal pressure loss on air motor pressure regulator gauge during both changeovers.
Abnormal A and B pump outlet pressure loss during both changeovers.
Air line restriction due to quick-disconnect pin fitting.
Air supply line ID to each feed pump is too small.
Reduced flow rate.
Off-ratio material.
Undersized air compressor.
Remove quick-disconnect from the air line and replace it with bleed-type air shutoff valve.
Replace with minimum 3/4 in. (19 mm) ID hose.
Replace with properly sized air compressor.
During normal operating conditions, the feed pump (A and B) air motors are filled with air almost instantaneously on both changeovers.
However, if the feed pump air supply is restricted, it can take significantly longer for air to fill the air motor. To check for this, observe the gauge on the air motor pressure regulator during both changeovers:
• At the end of each stroke the air pressure will drop abnormally as the air motor begins to fill.
• At the same time the A and B pump outlet pressures will drop abnormally due to the feed pump’s respective air motor’s reduced pressure.
• The decrease in the pump outlet pressures causes the flow rate at the dispense gun to be reduced.
• Once the air motor has filled with air, all air pressures and flow rates will return to normal until the end of the next stroke.
• The decreased pump outlet pressure may affect the feed pumps’ checking action, and thus mix ratio, resulting in the dispense of what appears to be poorly mixed material.
• Changing air pressure changes the compression of the component A hose and material. This causes an off ratio condition until pressures stabilize. Equipment air supply pressure must always stay above the motor regulator setpoint.

Troubleshooting
Pump Troubleshooting
Overview
Pump Cavitation
Under normal operation, when the feed pump pressures are balanced, component A and component B outlet pressures are consistent.
Some up or down adjustments in feed pressures will be necessary to keep the pumps’ outlet pressures balanced. This is due to viscosity differences in the two materials, volumetric ratio, and required flow rate.
Because of the viscosity difference between the two materials, most of the balancing effect comes from adjusting the component A pressure. For ratios higher than 1:1, the component B pressure should be set only as high as necessary to avoid cavitation at the desired flow rate. For 1:1 ratio there is equal balancing from component A and component B pressure.
If either the A or B pump does not completely fill with material on intake, the failing pump’s material output is interrupted at the beginning of the next stroke. This is referred to as cavitation.
Pump A cavitation is detected by observing the inlet pressure gauges on pump A and pump B immediately after changeover. When cavitation occurs, the proportioner pump outlet pressure gauge drops and the pump
A outlet pressure gauge shows an increase in pressure, as described previously.
B pump cavitation is detected by observing the B pump inlet pressure gauge immediately after pump top changeover. When cavitation occurs, the B pump outlet pressure gauge drops.
If the amount of cavitation is moderate, the pressure gauges return to their normal readings at some point during the downstroke of the failing pump.
During pump A cavitation, the pressure drop may cause a noticeable reduction in flow rate at the dispense gun.
Additionally, the interruption in the pump A material output may cause component B-rich material to dispense, which may appear as poorly mixed material.
During B pump cavitation, the interruption in the B pump material output may cause component A- rich material to dispense, which may appear as poorly mixed material.
Pump Failure to Seal
Under normal operation, the output of the component A and component B pumps depends upon proper sealing of their internal packings.
If packings fail to seal properly, the pump material output, and thus the output pressure, is reduced. Depending on the location of the failure, the pressure reduction may occur on the pump upstroke, downstroke, or both strokes.
Component B Pressure Relief Valve
The proportioner includes a spring-loaded, overpressure relief valve, which bypasses component B back to the supply when pressures exceed 3400 psi (23 MPa,
234 bar).

Troubleshooting
Component B Injector
In most dispense systems, an injector is included in the component B fluid line. This injector adds back pressure to the system and provides the necessary pressure balance between component A and component B to achieve the proper ratio and mix.
If the injector becomes fouled with mixed material, the pressure indicated on the B pump outlet gauge will increase and upset the pressure balance, resulting in the dispense of poorly mixed material.
If the injector becomes completely plugged, only component A is dispensed from the gun and the B pump outlet pressure will increase until the relief valve discharges.
If the injector valve sticks, it can react sluggishly causing soft spots after valve triggering or changeover.
Keep the injector clean. Inspect the housing tip and needle end for dents or scratches. Lapping the needle to the housing with automotive lapping compound will recondition the seat/needle. When reassembling the injector, tighten the nut 2-2.5 turns after the slack is taken up.
It is good practice to have a clean injector on hand. A fouled injector can then be replaced quickly, and thoroughly cleaned and held for future use.
Preventive Maintenance
1.
Air supply: Oil level in main air line lubricator should be checked daily and refilled when necessary with
SAE 10W non-detergent oil. Adjust to dispense 1 drop per minute during operation.
Main air line filter should be drained as required.
Excessive amounts of water in the system will reduce machine performance.
2.
Housekeeping: Spilled materials on any part of the equipment should be cleaned up promptly. Your system is precision equipment and should be maintained as such. A light coating of petroleum jelly on components will often prevent spilled material from sticking to equipment.
3.
Pumps: Pump packing should be tightened daily the first week of operation and weekly thereafter.
4.
When using Throat Seal Lubricant (TSL) or ISO oil, the lubricant should be maintained at an adequate level in the pump packing reservoir. These lubricants prevent material from sticking to pump rods, extends packing life, and protects material from contamination from the atmosphere.
Use ISO oil when dispensing moisture-sensitive materials.
Meter: Maintain TSL or ISO oil in reservoir if used; grease zerk fitting. Clean up spills as soon as possible to prevent damage to the meter.
5.
Mixer: With most materials, frequent use of equipment is all that is needed to prevent internal curing.
Some materials have a tendency to cure slowly on the walls of the mixing chamber. Experience will dictate how often the mixer or mixer elements should be thoroughly cleaned or replaced.
6.
O-rings/Seals: O-rings and seals will be damaged if soaked in solvents. When reusing, wipe with solvent and dry immediately.
