Important: Amplification Ratio:

For best results and longer pump life, it is recommended that a pressure regulator be used upstream of the pump timer to properly adjust the supply pressure. The supply to the pump timer should be a minimum of 15 psig and a maximum of 110 psig. Check the "Selection Chart" at the front of this manual for the Amplification Ratio for the pump being used.

How to Determine Desired Supply Pressure:

Assuming a process line pressure of 1000 psig, simply divide this pressure by the amplification ratio to determine the minimum required air or gas pressure. In the case of the Model 84T-12-x2 where the amplification ratio is 30:1 (which indicates that for each 1 psig of supply pressure the pump can produce 30 psig of discharge pressure) divide 1000 by 30 equals 33 psig. In practice, the regulator should be set approximately 15 psig greater than the calculated value to ensure positive injection of the chemical. This would provide a regulator setting of 33 + 15 = 48 psig. Proper air or gas pressure will provide longer pump life and reduce maintenance.

Note:

at the front of this manual.

Do not exceed maximum discharge pressure of the pump as shown in the "Selection Chart"

Scope Of This Manual:

This manual describes and provides instructions and parts list for the LINC84T-10, 11, 12 & 14 Series Chemical Metering Pump. This pump is a pneumatically operated plunger pump.

1. Figure 1 of this manual is the sectional drawing and parts list for the LINC84T-10, 11 & 14 Chemical Metering Pump.

2. Figure 2 of this manual is the sectional drawing and parts list for the LINC84T-12 Chemical Metering Pump.

Installation:

The LINC84T -10, 11, 12 & 14 require a flooded suction and must be located lower than the chemic al supply tank. Vertical installation of the piston housing is required.

1. Connect the suction line through a filter or strainer to the suction check valve (fig. 1, item 17 or fig. 2, item 16).

2. Connect the discharge line to the desired location.

Note: An in-line check valve at the point of injection is recommended to prevent back flow to the pump during shutdown or servicing.

3. Connect a supply pressure line to the timer (fig. 1, item 1 or fig. 2, item 1). Air is the recommended supply; however , any dry filtered gas may be used. The supply pressure to the timer must be regulated between 15 psig and 1 10 psig.

4. Set the regulator to the proper pressure to overcome the discharge pressure required by the pump. Refer to the paragraph on "Amplication Ratio" in this manual to determine the correct supply pressure.

5. To prime the pump, loosen the bleed screw (fig. 1, item 18 or fig. 2, item 18). Allow the liquid (chemical) to flow into the pump chamber, venting the trapped air or gas. Tighten the bleed screw.

6. Start the pump and run for a minimum of one minute. Open the bleed screw again and evacuate all the remaining air or gas from the pump chamber.

7. Using a rate gauge, set the desired pumping rate by adjusting the timer knob and stroke adjustment screw. The timer can be set to stroke the pump from 4 strokes/ minute to the maximum rate for the particular pump being used. See selection chart in this section of the manual.

8. The stroke length is adjusted by rotating the stroke adjustment screw (fig. 1, item 5 or fig. 2, item 4) on top of the piston housing (fig. 1, item 8 or fig. 2, item 6). Loosen the jam nut and adjust the stroke adjustment screw as necessary (fig. 1, item 4 or fig. 2, item 5). Lock down the jam nut after any adjustments are made.

Note: The minimum stroke on the 84T -10, 11 & 12 is 1/8" and 1/4" on the 84T-14.

Maintenance:

Refer to all sectional drawing and parts list in this manual. All repairs should be performed in a clean environment.

The following steps must be taken before proceeding with any maintenance operations:

Removing the Pump from Service:

1. Rotate the control knob on the timer to the "O" position.

2. Disconnect the supply pressure from the timer.

3. Close the upstream and downstream valves on the chemical lines.

4. Open the bleed screw to release the pressure in the pump.

5. Disconnect the suction and discharge lines from the check valves.

4. Separate the three timer sections and discard the seal, diaphragm and the disc (fig. 3, items 4, 6 & 15). Be careful not to lose the small disc spring (fig. 3, item 16). Note the orientation of the diaphragm as it is removed.

5. Loosen the set screw on the knob (fig. 3, item 11). Remove the knob and knob spring (fig. 3, item 9).

6. Unscrew the adjustment screw (fig. 3, item 10) from the front body (fig. 3, item 13). Remove and discard the oring (fig. 3, item 12).

7. Reassemble the timer in reverse order of the above steps, using new rubber parts. Lubricate the adjustment screw threads and its o-ring. No other lubrication is required.

8. After installing the adjustment screw , turn it in by hand without the knob installed until it lightly seats. During this operations do not overtighten the adjustment screw into its seat. Apply supply pressure to the timer and unscrew the adjustment screw slowly until the pump starts to run. Trial and error will be necessary to determine the proper orientation of the knob on the adjustment screw . Once the proper orientation is determined, reinstall the knob spring and knob.

Scope Of This Manual:

This manual describes and provides instructions and parts list for the LINC84T-13 Series Chemical Metering Pump. This pump is a pneumatically operated plunger pump.

Installation:

The LINC84T-13 pump requires a flooded suction and must be located lower than the chemical supply tank. Vertical installation of the piston housing is required.

1. Connect the suction line through a filter or strainer to the suction check valve (fig. 1, item 19).

2. Connect the discharge line from the discharge check valve to the desired location (fig.1, item 18).

Note: An in-line check valve at the point of injection is recommended to prevent back blow to the pump during shutdown or servicing.

3. Connect the supply pressure to both the timer and the relay (fig. 1, items 1 & 3). Air is the recommended supply; however , any dry filtered gas may be us e d . The supply to the timer and relay must be separate. T wo filter-regulators are required, one to control the supply pressure to the timer and another to control the supply pressure to the relay.

4. Using the regulator that feeds the supply to the relay , set the supply pressure to overcome the discharge pressure of the pump. T o do this, divide the discharge pressure by the Amplication Ratio and add approximately 10 psi to ensure positive injection of the chemical. Refer to "How T o Determine Supply Pressure," in this section of the manual.

5. Assure that the control knob on the timer is set so that the pump will not stroke over 45 strokes per minute.

6. Slowly increase the supply to the timer , using the regulator that feeds the timer , until the pump begins to stroke smoothly. This pressure should be in the 20 to 40 psig range depending on the supply to the relay.

7. To prime the pump, loosen the bleed screw (fig. 1, item

21) allowing the liquid (chemical) to flow into the pump chamber, venting the trapped air or gas.

8. After the liquid exits, tighten the bleed screw and start the pump and run for a minimum of one minute. Open the bleed screw again and evacuate all the remaining air or gas from the pump chamber.

9. Using a rate gauge, set the desired pumping rate by adjusting the timer knob and

stroke adjustment screw . The timer can be set to stroke the pump from 4 strokes/minute to the maximum rate of 45 strokes/minute.

10. The stroke length is adjusted by rotating the stroke adjustment screw (fig. 1, item 7). on top of the piston housing (fig. 1, item 9). Loosen the jam nut and adjust the stroke adjustment screw as necessary (fig. 1, item 8). Lock down the jam nut after any adjustments are made.

Note: The minimum stroke on

the 84T-13 is 1/4".

Maintenance:

Refer to all sectional drawings and parts list in this manual. All repairs should be performed in a clean environment.

The following steps must be taken before proceeding with any maintenance operations:

Removing the Pump from Service:

1. Rotate the control knob on the timer to the "O" position.

2. Disconnect the supply pressure from the timer and relay .

3. Close the upstream and downstream valves on the chemical lines.

4. Open the bleed screw to release the pressure in the pump. check valves.

IMPORTANT: How To Determine Supply Pressure:

The theoretical amplification ratio shown in the Selection Chart of this manual is the area of the piston divided by the area of the plunger. This amplification ration is used to determine how much gas supply pressure is required to enable the pump to generate the required liquid discharge pressure. The theoretical gas supply pressure required to generate a specific liquid discharge pressure is calculated by dividing the required liquid pressure by the amplification ratio. However, the amplification ratio is a theoretical number and in an actual application, other factors such as friction and stroke rate require that a higher gas supply pressure be used.

To determine the approximate gas supply pressure to the relay, add 10 PSI to the calculated theoretical gas supply pressure.

Example: The LINC84T-13-x4 is capable of pumping up to a maximum of 9,000 psig. The Amplification Ratio for this pump is 60:1. Assume that we are going to be pumping into a system that is at 6,500 psig. Then 6,500 divided by 60 equals 108 psig; add 10 psig to the 108 psig which equals 118 psig as your result. Set the regulator that feeds the relay at 118 psig.

The supply pressure to the timer of the 84T should be set high enough to make the relay stroke reliably. The timer supply pressure must be equal to or slightly lower than the relay supply pressure..
