Unpacking
Unpacking the Product
The Dynastarr pump module was carefully packaged
for shipment by Graco. When the package arrives,
perform the following procedure to unpack the units:
1. Inspect the shipping box carefully for shipping
damage. Contact the carrier promptly if damage is
discovered.
2. Unseal the box and inspect the contents carefully.
There should not be any damaged parts.
3. Compare the packing slip against all items in-
cluded in the box. Any shortages or other inspec-
tion problems should be reported immediately.
4. Store the box and packing materials in a safe
place for future use. Graco recommends that all
packing materials be saved in case the unit needs
to be shipped again.
Pump Module Overview
Pump Module Capabilities
The Pump Module provides lubricant flow and pres-
sure to operate a single line parallel automatic lubrica-
tion system. The module requires a hydraulic power
Supply and a timed signal from a lubrication controller.
Based on these signals, the pump module provides
lubricant flow and pressure to operate the injectors and
vents the injector system to reset the injectors.
Pump Module Operation
Pump Module Operation performs these cycles:
1. Upon receiving a signal from a 24 volt lubrication
controller, the 3–way solenoid valve (Fig. 3,
item F) opens, starting the pump (D) and closing
the vent valve (U).
2. The pumps builds pressure until the pressure
switch in the system sends a signal to the timer,
ending the cycle, or the pump stalls.
3. The timer terminates the 24 volt signal to the
3–way solenoid valve (F).
4. The 3–way solenoid valve (F) closes, stopping the
pump and opening the vent valve (U).
5. The system lubricant pressure bleeds back
through the vent valve (U) into the reservoir (P).
6. The pressure reducing valve (PRV) (item S) and
flow control valve (FCV) (item N) control the pump
output pressure and cycle rate.
