Installation
Installation
Grounding
Maximum Working Pressure of Accessories
To reduce the risk of serious injury including fluid injection and splashing in the eyes or on the skin, which may be caused by component ruptures, all accessories added to the reciprocator power supply side of the pump fluid outlet side must have at least a
1500 psi (10 MPa, 103 bar) maximum working pressure.
Pump Accessories
Suction Tube Kit: A suction tube kit is available for siphoning from 55 gallon containers.
Intake Tube: To install, apply PTFE tape to the female threads at the top of the tube (Q). Screw the tube tightly into the intake housing of the stubby pump.
Low-Level Cutoff Valve: To install, screw the low-level cutoff valve into the bottom of the pump intake tube or the suction tube. This valve closes the pump intake when the fluid level is low, causing the pump to stall to avoid running all day.
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.
Pump: Use a ground wire and clamp. Remove the ground screw (Z) and insert through the eye of the ring terminal at end of ground wire (Y). Fasten the ground screw back onto the pump and tighten securely. Connect the other end of the ground wire to a true earth
Z
NOTICE
A pump outlet drain valve is required in the system.
This valve helps relieve pressure in the displacement pump and hose when shutting down the system and in case of a clogged outlet hose.
Install the valve hose close the pump outlet.
Y
Pump Outlet Drain Valve: Install a drain valve (D) close to the pump fluid outlet assist in relieving fluid pressure in the pump, hose, and dispense valve when the pump is shut off.
Thermal Relief Kit: Install a Thermal Relief Kit (T) at the pump fluid outlet.
F
IG
. 1
Hydraulic and fluid hoses: Use only electrically conductive hoses.
Hydraulic power supply: Follow manufacturer’s recommendations.
Any pails used when flushing: Use only metal, grounded pails when flushing. Make firm metal-to-metal contact between the metal part of the dispense valve and the pail. Use the lowest possible pressure.

NOTE: The installation shown in F IG . 2 is only a guide.
For assistance in designing a system to suit your needs.
Contact your Graco representative.
Mount the pump to suit the type of installation planned.
Hydraulic Power Supply
To reduce the risk of damaging the hydraulic power supply, blow out all hydraulic lines with air, flush thoroughly with solvent, and then blow out with air again before connecting the lines to the motor.
Always plug the hydraulic inlets, outlets, and lines when disconnecting them to avoid introducing dirt and other contaminants to the system.
Carefully follow the manufacturers recommendations on reservoir and filter cleaning, and periodic changes of the hydraulic fluid.
6 308391H
Installation
Hydraulic Components
Always turn off the hydraulic supply side valve (K) first to avoid possible serious injury or component
damage. See the Typical Installation on page 6.
Drain Line: Remove the plug (24) from the pump adapter, and install a 1/8 inch diameter weep tube, ending in a waste container. Monitor the weepage of hydraulic fluid. If it seems excessive or increases suddenly, the reciprocator or pump throat seals may need to be changed. (F
IG
. 3)
Hydraulic Fluid Control: The hydraulic fluid control pro-
vides pressure regulator, and pump isolation. (F
Pressure Regulation: The hydraulic fluid control reduces the hydraulic oil pressure to the operating pressure required for the application.
Flow Regulation: The hydraulic fluid control limits the maximum amount of oil flow to the motor to keep the hydraulic motor within the cycle rate limit. This prevents pump runaway. The limit on the Power-Star is 66 cpm.
Pump Isolation: The hydraulic fluid control has ball valves on the supply and return sides of the manifold.
The ball valves isolate the hydraulic fluid control and pump for servicing without stopping the hydraulic power supply.

Operation
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever you see this symbol.
Before Starting the Pump
This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.
1.
Close the supply line shutoff valve, and then the return line shutoff valve.
2.
Open the dispensing valve to relieve the pressure.
3.
Place a container under the drain valve to catch any drainage. Open the pump outlet drain valve.
4.
Leave the drain valve open until you are ready to dispense again.
NOTE: If you suspect that the dispensing valve, exten- sion, or grease fitting coupler is clogged, or that the pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen the coupler or hose end coupling and relieve pressure gradually, then loosen completely and clear the clog.
Recommended Hydraulic Oil
Use a Graco-approved Hydraulic Oil or a premium, ISO grade 46 petroleum-based hydraulic oil containing rust and oxidation inhibitors and anti-wear agents.
Before using any other type of oil in this motor contact your Graco distributor. Unauthorized use of lesser grad oil or substitutes may void the warranty.
1.
Check the hydraulic fluid level in the hydraulic power supply before each use, and add fluid as necessary to fill the lines.
2.
Flush the pump before using it for the first time to remove the light oil that was left in after factory testing to protect the pump from corrosion. Be sure the solvent used is compatible with the fluid to be pumped and the pump’s wetted parts. See Techni-
cal Data, page 19. Flush until clean solvent comes
from the outlet hose.
To Start the Pump
1.
Turn on the hydraulic power supply.
2.
Open the return line shutoff valve (H) first, and slowly open the hydraulic supply line shutoff valve
3.
Adjust the hydraulic inlet pressure from 500 to 1500 psi (3.5 to 10.3 MPa, 35 to 103 bar) with the regulator control adjustment (M) on the hydraulic fluid control (A). Increasing the inlet pressure increases the outlet pressure. Decreasing the inlet pressure decreases the outlet pressure.
4.
Always use the lowest pressure possible to obtain the desired results. This reduces pump wear.
308391H
5.
Never allow a pump to run dry of the fluid being pumped. A dry pump quickly speeds up and can damage itself. If it speeds up, shut off the power supply to the reciprocator immediately. Refill the supply container and prime the pump to eliminate air.
NOTE: To prevent the pump from running dry, use a low-level cutoff valve.
Shutdown and Care
At the end of the work shift or when the pump is unattended, always relieve the pressure, see Pressure Relief
Emergency Stop Procedure
Close the supply line shutoff valve marked STOP.
