Flush the pump and the high-pressure tubing
It is common for small pieces of metal and debris to be present in newly installed high-pressure
tubing. Flush the system to prevent damage to orifices, on-off valve parts, and other components of
the high-pressure system.
1. Remove the cutting head and the orifice.
2. Make sure that the on-off valve is closed.
3. Turn
ON
the pump.
4. Set the pressure to 1,380 bar (20,000 psi).
5. On the operator interface, touch the S
TART
symbol.
6. Make a program that turns the valve on and off in 1-second increments. Operate the program in
a loop for 15 minutes.
7. Turn
OFF
the pump.
8. Install a ruby orifice in the cutting head.
9. Turn
ON
the pump.
10. On the operator interface, touch the S
TART
symbol.
11. Increase the pressure to 2,760 bar (40,000 psi). Operate the program in a loop for 15 minutes.
12. Increase the pressure to 4,140 bar (60,000 psi). Operate the program in a loop for 15 minutes.
The pump is ready for operation.
CAUTION
This procedure can cause damage to the on-off valve needle and the seat and to the orifice.
Keep spare parts and orifices available.
If this pump was purchased through an OEM, the OEM could recommend a different
procedure to flush out the high-pressure tubing.
CAUTION
If a program is not available, turn the cutting head on and off in 1-second intervals
for 15 minutes. This loosens debris in the high-pressure tubing.
If the on-off valve leaks, examine the needle, the seat, the seals, and the orifice for
damage. Replace parts, if necessary.
