Overview
Overview
An electric motor (B) provides input to a 75:1 gear
reducer (GR), which drives two fluid pumps (FP). See
F
IG. 1. The stroke positions of the two pumps are offset
to achieve consistent flow from the pump assembly. See
F
IG. 2.
B
GR
TDC (behind
PT
cover)
The optional sensor circuit includes a top dead center
(TDC) sensor which assists software in measuring
motor speed, and a pressure transducer (PT) with circuit
board, which measures fluid pressure at the pump outlet. The Graco VFD software mimics the effect of a camshaft, constantly adjusting motor speed to keep steady
fluid flow and achieve minimal pressure variation. The
output shaft of the gearbox and the connecting rods
experience the effect of the imaginary camshaft by
speeding up when the pressure drops (pump lower is at
a changeover) and slowing down when pressure
increases (both lowers are pumping).
The VFD can be controlled by a local control box
mounted in the hazardous area, via communication protocol (such as modbus), or directly from the keypad.
F
IG. 3 shows a layout of a typical North American sys-
tem. The pump (A) may be controlled by a local control
box (C) mounted in the hazardous area, a variable frequency drive (D) mounted in the non-hazardous area, or
remotely from a computer (Y). See manual 311592 for
pump and accessory installation information.

Ground the System
Ground the System
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Ground the following equipment:
• Pump: use ground screw (GS) to attach a ground
wire (Z) to the pump. Tighten the screw securely.
Connect the other end of the ground wire to a true
earth ground.
Z
• Variable frequency drive: grounded through proper
connection to power source.
• Local control box: follow your local code.
• Fluid supply container: follow your local code.
• Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place pail on a
nonconductive surface, such as paper, plastic, or
cardboard, which interrupts grounding continuity.

Preventive Maintenance Schedule
Establish a preventive maintenance schedule based on
the equipment’s repair history.
Check Gear Reducer Oil Level
Every day, check the oil level in the sight glass (SG) on
the gear reducer, with the motor running. Oil level (with
motor running) should fall between top and bottom of
the sight glass (SG). Open the fill cap (FC) and fill the
gear reducer oil reservoir as required with Graco
288414 Oil (package includes twelve 1 quart bottles).
Do not overfill. See F
FC
IG. 8.
NOTE: A faint clicking may be heard while the motor is
running. This is normal and is due to necessary clearances between the coupler (28), motor shaft, and motor
key. If the intensity increases significantly over time, it
could indicate the coupler is wearing and should be
replaced. Do not open the gear reducer. The gear
reducer is not field serviceable beyond the maintenance
recommended in this manual

Maintenance
Flushing
• Flush before changing colors, before storing, and
before repairing equipment.
• Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Follow Pressure Relief Procedure, page 14.
2. Supply the appropriate flushing material to the sys-
tem.
3. Set pump to lowest possible fluid pressure, and start
the pump.
4. Flush long enough to thoroughly clean the system.
5. Follow Pressure Relief Procedure, page 14.
How long TSL lasts depends on which chemicals are
used, how much is used, what pressure, and condition
of the pump seal and rod.
A drop in the level of TSL in the reservoir indicates that
the throat packings are starting to wear. Add TSL to the
reservoir and keep the level above the Minimum fill line.
Monitor the usage and condition of the TSL. If pumped
material bypasses the throat packings and enters the
TSL reservoir, replace the packings.
To change the TSL:
1. Shut off the pump.
To avoid the buildup of static charge, do not rub the
plastic bottle with a dry cloth while it is attached to the
pump. Remove the bottle to clean, if needed.
2. Remove and empty the reservoir bottle. Clean any
residue.
Changing the TSL
Check the condition of the TSL and the level in the reservoir every week, minimum. TSL should be changed at
least every month.
Part No. 206995 Throat Seal Liquid (TSL) carries residue from the pump rod into the reservoir. Discoloration
of the TSL fluid is to be expected during normal operation. After some time the TSL will thicken and darken,
and must be replaced. Thick, dirty TSL will not pump
through the lines and will harden in the pump wet-cup.
VO
VI
3. Clean screen (Z) of inlet check valve (VI). If check
valves are not sealing and dirty TSL is getting into
the wet-cup, replace the check valves (VI, VO). See
F
IG. 11.
4. Fill the reservoir to the Maximum fill line with Throat
Seal Liquid (TSL).
5. Run pump. Each time pump rod reaches bottom of
stroke, check that some TSL is pumped from reservoir through wet-cup and back to reservoir.

Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with
structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of
the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned
to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will
be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.
