Unpacking

Unpacking

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 Module Overview

Pump Module Capabilities

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.

Pump Module Operation

(See FIG. 4, page 8)

Cycles for Pump Modules 247444 and 247574 for injector-based, Automatic Lubrication Systems

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.
