Overview of Product
63A8597B
Overview of Product
The ProMix PD Proportioner Platform TSL (Throat Seal
Lubricant) Auto Lube System adds an automated
replenishment supply of fresh TSL to the ProMix PD
critical pump throat cartridge areas.
In applications wheredifficult materials such as moisture
sensitive isocyanate catalysts are used, a regular supply
of fresh TSL helps flush away contaminates that would
otherwise crystallize or harden and cause reduced
pump u-cup seal life.
Typical Installation
This following figure (FIG. 1: Typical ProMix PD Proportioner Platform TSL Auto Lube System Installation),
along with the detailed descriptions, explain the function of all the components. Items outlined in black are included
with the product. Items outlined in gray are supplied by the user.

Installation
3A8597B 7
A typical installation, as shown in FIG. 1, consists of the
following (see also Parts, page 16, for quantities for
each model):
A AC-powered G3 Pro Automatic Lubrication Pump
(included) with an integrated On/Off programmable
timer.
B 600 psi Pressure Relief Valve (included) at the
pump outlet to protect the system from
over-pressurization in the case of a blocked fluid
line.
C Graco CSP series progressive divider valve
(included) to equally and sequentially direct flow
from the G3 Pro Automatic Lubrication Pump into
the number of lubrication points desired (one CSP
outlet port per ProMix PD throat cartridge lube
point).
D ¼” OD fluid tubing (included) and push-to-connect
fittings (included) to connect the G3 Pro Automatic
Lubrication Pump to the CSP inlet and outlet ports
to lube points on the ProMix PD pump cartridges.
E Barb fittings (included) and clear flexible
polyurethane tubing (included) to connect to ProMix
PD throat cartridges for routing used TSL fluid to a
waste container.
F Additional ProMix PD u-cup seals (included; 1 per
catalyst pump) and pump lower rod guards with TSL
ports (included; 1 per catalyst pump) to upgrade all
catalyst pumps with a fourth u-cup seal and ported
lower rod cover. See FIG. 4 for details. These parts
provide secondary protection below the primary
catalyst throat cartridge area. This secondary
protection keeps the pump rod flooded in TSL and
provides the regular exchange of TSL between the
enclosed rod section and the standard TSL
reservoir originally provided with the ProMix PD
unit.
G Extra TSL port fittings (included) and plugs
(included) for use as needed.
H TSL reservoir(s) originally provided with the ProMix
PD system. Used for lubrication to the pump dose
valves and to the catalyst ported lower rod cover
(item F) provided in the auto lube kit. Reference
page 3 for quantity of rod covers provided in each kit
and information to order additional sets.
Installation
Grounding
G3 Pro Automatic Lubrication Pump: See the G3 Pro
Automatic Lubrication Pump manual for proper
grounding.
Waste pail: Follow local code. Use only conductive
metal pails, placed on a grounded surface. Do not place
the pail on a non-conductive surface, such as paper or
cardboard, which interrupts grounding continuity.
All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Installation
83A8597B
Before Installation
Relieve pressure and power down the ProMix PD pump
before installing this system. Follow the Pressure Relief
Procedure in your ProMix PD Operation manual.
G3 Pro Automatic Lubrication
Pump
See G3 Pro Automatic Lubrication Pump manual for
proper installation, setup, and operation of the G3 Pro
Automatic Lubrication Pump. The G3 Pro Automatic
Lubrication Pump is tested with lightweight oil at the
factory.
CSP Valve
See the CSP Valve manual for proper installation and
operation of the CSP valve. The CSP valves are tested
with lightweight oil at the factory.
NOTE: DO NOT plug any unused CSP divider valve
outlet ports or allow blockage of the fluid lines
downstream of the divider valve. The CSP is a series
progressive valve, which means that as fluid is pumped
into the inlet port, a series of internal precision pistons
progressively cycle while dispensing equal volumes
sequentially from the outlet ports. Blockage of ANY
outlet port will completely restrict fluid flow to all ports.
The upstream pressure will increase until the pressure
relief valve at the G3 Pro pump outlet opens. Refer to
the CSP Valve manual for alternate valve port options.
NOTICE
The CSP Valve is a precision machined device with
close-fitting internal pistons. Dirt, foreign materials,
and contaminates allowed to enter the lubricant sys-
tem can cause damage and complete restriction or
damage of the CSP Valve.
Always clean the G3 Pro reservoir fill cap area (FIG.
2) with a clean dry cloth prior to filling reservoir. Only
use clean, fresh lubricate to prevent contamination
and damage to system.
FIG. 2: G3 Pro Automatic Lubrication Pump
NOTICE
Fittings without a clamping ring cause the lubrication
system to fail. Clamping rings insure the proper
amount of lubrication is directed to each of the outlet
ports. Without proper fittings some lube points may
receive lower amounts or no lubrication leading to
premature failure of the PD seals.
Always use the Graco provided block outlet fittings
with clamping rings in the block outlet.
Refer to the CSP Valve manual for a complete list of
available outlet fittings.

Installation
3A8597B 9
CSP Valve Port Combinations
The output of a CSP valve outlet can be increased by
installing Graco specific Doubling Plugs (9) in an
adjacent outlet. When one or more outlets are plugged,
the output is a multiple of the standard output.
Some kit configurations have Doubling Plugs (9)
installed. The CSP outlet port is a straight M10x1
thread. Always use Graco fittings.
CSP Indicator Pin
The CSP valve is equipped with a Cycle Indicator Pin
(FIG. 3). The indicator pin is connected to the internal
pistons and moves back and forth during one of the
movements and as TSL lubricant is distributed.
The indicator pin can be a useful tool for
troubleshooting. If there is a blockage downstream of
the CSP valve in any of the outlet lines, the valve and
the indicator will stop cycling.

NOTICE
Assemble CSP Valves with Outlet Fittings (6) and Doubling Plugs (9) per Table 1: CSP Valve Port Usage.
Do not close, plug, or install any type of plug into ports numbered 1 and 2, including Graco Doubling Plug (9).
If ports 1 or 2 are plugged, the CSP valve will not allow lubricant to flow at all. If the fitting location shown in Table
1 is not followed, CSP outlet lubricant points may be under- or over-lubricated, potentially causing premature fail-
ure of the PD seals.

Catalyst Pump Seal and Rod Guard Installation
The following installation steps are necessary to insure
proper containment and flow of fresh TSL through the
PD pump wet cup area and extend the life of the primary
pump u-cup seal. Following these steps also provide
lubrication around the pump displacement rod inside of
the rod guard.
1. Follow the Pressure Relief Procedure in your
ProMix PD Operation manual.
2. Install the 4th pump u-cup seal (11) into the Packing
Nut with the seal lips facing upward toward the
pump. See FIG. 4 and the PD Dosing Pumps
manual for instructions.
3. Install the modified rod guard (13) with the four
10-32 UNF ports provided.
4. Route a single TSL line (18) to the existing reservoir
using the supplied barb fittings (17), clear
polyurethane tubing (18), and plugs (15) and
gaskets (16) as necessary.
5. Fill the TSL Reservoir and bleed air from the lower
rod to ensure the rod remains wetted during
operation. See Plumbing, page 10.
As the pump cycles, the pump displaces TSL from the
lower rod guard into the reservoir on the down stroke
and pulls fluid into the lower guard area on the upstroke.
Monitor and replace TSL in the reservoir as needed.
The majority of any catalyst seepage past the primary
pump u-cup seal will be flushed clear of the throat
cartridge by the TSL Auto Lube System.
Plumbing
Route and install TSL tubing per FIG. 5. Consult the
parts list on page 17 to ensure the correct tubing and
fittings are used for each location in FIG. 5. See the note
under CSP Valve, page 8, regarding the requirement
that unused outlet ports NOT be plugged.
Use 1/4" OD fluid tubing and push-to-connect fittings:
• To connect the G3 Pro Automatic Lubrication Pump
to the CSP inlet.

Operation
Prime the ProMix PD TSL Auto Lube
System
1. Fill the G3 Pro fluid reservoir with Graco Throat Seal
Lubricant (TSL). (See the G3 Pro Automatic
Lubrication Pump manual, “Filling Oil Unit”.)
2. To prime the system for the first time -
a. Set the ON Time to 15 minutes. (See G3 Pro
Automatic Lubrication Pump manual,
“Instructions/ON Time/Programming ON Time”.)
b. Prime the G3 Pro pump and start the pump
using the Manual Run button. (See the G3 Pro
Automatic Lubrication Pump manual, “Priming”
and “Control Panel Overview”.)
c. Observe the TSL fluid flow through the main line
from the G3 Pro pump to the CSP divider valve,
and then out to each lube point and into the
waste container. It will take several minutes to
fill out the fluid lines.
d. Repeat the Manual Run cycles as needed to
fully prime and fill all lines.
ON/OFF Time Guidelines
Based on each installation and application ON times
and frequency of automatic lubrication needs will vary. If
you have experienced rapid contamination of a ProMix
PD pump TSL or a short pump seal life without an Auto
Lube system installed, it is recommend that you start
with a relatively high ON time and frequency (lower OFF
time between ON time cycles). Monitor the TSL waste
for contamination and adjust accordingly.
Pump seal life varies greatly depending on the types of
fluid used, though one of the most important
preventative maintenance steps that can extend the
pump life is regular and proper TSL lubrication. The TSL
maintains a barrier to slow the process of paint drying or
catalyst reacting with moisture in the air and
crystallizing. Replacing stagnant TSL with fresh TSL
clears the contamination away from the seal/rod
interface area which then slows the wear process and
leads to longer seal life.
NOTE: See Table 2: ON Time per Lube Point, page
13, for recommended ON/OFF Times for your ProMix
PD TSL Auto Lube system. A good starting point is to
provide 2 cc per lube point of the TSL per hour. On a
new installation, closely monitor the condition of the
waste TSL for any contamination and adjust the
lubrication amount up or down as needed. The G3 Pro
pump will continue to run the programmed ON/OFF
cycle times when the unit is powered regardless if
ProMix PD operation is occurring or not (e.g. off shift or
weekends). Shut power off to the G3 Pro pump if you do
not want automatic fresh TSL dispensing to continue.
When powered is restored the pump will resume the
cycle with the same amount of time remaining in the
cycle as when the power was turned off (unless you
have the Prelube feature enabled on the G3 Pro pump).
Monitor the G3 Pro fluid reservoir level and replenish
with TSL before it runs low. Running the unit out of fluid
supply will allow air to enter the fluid lines which can
introduce moisture (humidity) and cause catalyst to cure
and damage the ProMix PD u-cup seals. If air is
introduced into the fluid stream repeat the priming
procedure above until all air is purged clear of the
ProMix PD throat cartridges. A low level detection kit is
available as an accessory for the G3 Pro pump.
G3 Pro pump volumetric output is approximately 4
cc/min. Output flow rate is dependent on the fluid
viscosity and the pressure. For a low pressure
application with the TSL lubricant, the fluid’s actual
volume output will be slightly higher, but consistent over
time. Therefore, use Table 2: ON Time per Lube Point
as a guide for initial timer settings.

Operation
3A8597B 13
ON/OFF Time per Lube Point Table
Use Table 2: ON Time per Lube Point as a guideline
for programming system ON and OFF times (see the G3
Pro Automatic Lubrication Pump manual,
“Instructions/ON Time and OFF Time”). The table
provides approximate volumes of fresh TSL lubricant
supply to the ProMix PD pump cartridge areas based on
the number of lube points and ON Times. Monitor waste
fluid lines and container for levels of contaminate and
adjust pump ON/OFF times as needed.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
To relieve pressure in your ProMix PD proportioner,
follow the pressure relief procedure in your ProMix PD
Operation manual.
Relieve pressure in auto lube system using two
wrenches working in opposite directions on the G3
pump element and the pump element fitting to slowly
loosen fitting only until fitting is loose and no more
lubricant or air is leaking from fitting.
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.
Maintenance
Catalyst Pump Rod Guard TSL
Maintenance
To extend pump life, bleed fresh TSL into the rod guard
during TSL replacement. The bleed process ensures
that all of the air is removed from the rod guard and
bearing cartridge, eliminating wet air contamination
during the TSL replacement process.
1. Follow the pressure relief procedure in your ProMix
PD Operation manual. Shut off the PD unit.
2. Remove and thoroughly clean the rod guard.
3. Refill the rod guard (13) with TSL.
4. Place the rod guard (13) over the lower piston rod.
a. Partially thread the rod guard (13) onto the
pump but do not seat the rod guard o-ring (12)
against the pump. This allows air to bleed when
filling the TSL
b. Connect the TSL reservoir hose (18) to the
guard barb fitting (17).
5. Fill the Reservoir, and let gravity fill the TSL lines.
6. Thread the guard back on the pump when the TSL
begins to overflow the guard.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid, follow the
Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing the
equipment

Troubleshooting
3A8597B 15
Troubleshooting
The indicator pin on the CSP valve should periodically
cycle in and out when the fluid is properly flowing
through the valve.
Internal blockage due to contamination, physical
restriction of the pistons, or blockage to any of the
downstream fluid lines will cause the CSP valve to stop
all flow through the device. To address this, verify there
is no blockage in the fluid lines downstream of the CSP
valve. Refer to the CSP Valve manual for information on
blockage and for cleaning the valve.
For other Troubleshooting issues, refer to the G3 Pro
Automatic Lubrication Pump manual.
NOTICE
To prevent premature ProMix PD seal wear and fail-
ure, insure TSL tubing lines are securely anchored.
Fluid pressure may cause the lines to develop leaks
or separate from the barb fitting. Fluid pressure in the
TSL line can be caused by either of the following:
• The rod guard displacement-flow volume through
the bearing and barb fittings during high-cycle
rates of the pump.
• The filling and the color change process.
To reduce hose flexing and the likelihood that the
hoses work their way off of the barb (possibly loosen-
ing and creating a leak area), route and anchor the
TSL lines to prevent equipment damage.
NOTICE
If the TSL tubing lines become contaminated with
catalyst material, the TSL tubing should be replaced
to prevent premature ProMix PD seal wear and fail-
ure.
NOTICE
If the indicator pin does not cycle, the downstream
lubrication points will not receive fresh lubricant and
will likely cause premature wear and PD seal failure.
Refer to the CSP Valve manual for details on how the
divider valve functions and for proper outlet fitting
installation.
