Operating an integrated HyperJet pump
All integrated Flow intensifier pumps are operated using
the FlowMaster software controller. See manual M-322,
FlowCUT User's Guide, for more detailed information
on running the machine. A pump operation button on
the FlowMaster Run Machine screen is used for starting
and stopping the pump. Select HIGH PRESSURE or
LOW PRESSURE for the dual- pressure feature.
IMPORTANT
If you are running a standalone HyperJet intensifier
pump, it will have its own control panel. Turn to Chap-
ter 3 of this manual for details.
Running the pump
When the machine is in position to start a cut, click on
the ON pump button. The intensifier pump will not start
immediately; first the water booster pump turns on to
charge the system. After approximately 5 seconds, the
intensifier pump starts and begins ramping up pressure.
The pump uses an electronic proportional control valve
to automatically ramp up high-pressure water. The digi-
tal high-pressure gauge on the FlowCUT screen indi-
cates the amount of water pressure in the system.
When the system reaches the desired operating pres-
sure, you can begin cutting. Click the OFF pump but-
ton to turn off the pump. All system pressure is bled to
0 psi within one second of shutting down the pump.
Using dual pressure
Brittle materials, such as glass, stone, or composites,
should be pierced at a lower operating pressure (such
as 20,000 psi/1379 bar). To select high or low pres-
sure, highlight either the HIGH PRESSURE or LOW
PRESSURE box to the right of the pump on/off button.
•
The default setting is HIGH PRESSURE, which is
normally set for an operating pressure of 87,000 psi
(6000 bar).
•
Selecting LOW PRESSURE will lower the pressure,
usually to between 15,000–20,000 psi (1034–
1379 bar).
Use the LOW PRESSURE setting together with the
FlowMaster PIERCE ALL HOLES FIRST function to
pierce holes in a given program before cutting.
