Graco 247444 Benutzerhandbuch

The Dyna-Star 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 included 
in the box. Any shortages or other inspection 
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 Modules 247444 and 247574 for 
Injector-based, Automatic Lubrication Systems: 
provide lubricant flow and pressure to operate a single 
line parallel automatic lubrication 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 Modules 247706 and 247707 for Single Line, 
Series Progressive-based, Automatic Lubrication 
Systems: provide lubricant flow and pressure to 
operate a single line, series progressive, automatic 
lubrication system. The module requires a hydraulic 
power supply and a timed signal from a lubrication 
controller. 

(See F

. 4, page 8)

1.

Upon receiving a signal from a 24-volt Lubrication 
Controller (J), the 3-way Solenoid Valve (F) opens, 
starting the Pump (D) and closes the Vent Valve (U).

2.

The pump builds pressure until the pressure switch 
in the system sends a signal to the Lubrication 
Controller (J), ending the cycle or Pump (D) stalls.

3.

The Lubrication Controller (J) terminates the 24-volt 
signal to the 3-way Solenoid Valve (F).

4.

The 3-way Solenoid Valve (F) closes, stopping the 
Pump (D) and opening the Vent Valve (U) into the 
Reservoir (P).

5.

The Pressure Reducing Valve (S) and Flow Control 
Valve (N) control the pump output pressure and 
cycle rate.

1.

Upon receiving a signal from the 24-volt Lubrication 
Controller (J), the 3-way Solenoid Valve (F) opens; 
starting the Pump (D).

2.

The Pump (D) provides lubricant flow and pressure 
until the Lubrication Controller (J) terminates the 
signal to the 3-way Solenoid Valve; stopping the 
Pump.

3.

The Pressure Reducing Valve (S) and Flow Control 
Valve (N) control the pump output pressure and 
cycle rate.
