Maintenance Procedure C
Replacing the Intensifier High-Pressure Cylinder
Service notes
•
Flow recommends that you service both of the
high-pressure cylinders on the intensifier at the same
time. This will prevent unnecessary downtime.
•
Cylinder failures that occur at the conical sealing sur-
faces of the cylinder can cause failures of the check
valve body (014420-1) or seal carrier (052190-1).
While the intensifier is open, it is a good idea to in-
spect the sealing surfaces of these components.
Tools required
1 in. open-end wrench

Service steps
1. Shut down the system.
WARNING
Place the main electrical disconnect in the OFF
position and bleed down the high-pressure lines.
Place an “Out of Service” tag on the main electrical
disconnect and lock it out. Failure to do so can cause
equipment damage or injury to personnel.
2. Disconnect the inlet water hose from the end cap.
3. Using two wrenches, disconnect the high-pressure
tubing from the check valve outlet adapter. Loosen
the other end of the tubing and move it out of the
way.
4. Unload the intensifier tie rods.

the Intensifier
5. Note the orientation of the check valve body by ob-
serving the position of the eccentrically positioned
outlet body relative to the intensifier. This is impor-
tant when reinstalling the check valve body—correct
orientation is critical to ensure the correct fit of
high-pressure tubing, which is affected by the eccen-
tricity of the outlet body.
Note
: The check valve body is usually positioned so
with the outlet body away from the intensifier mani-
fold block, but this may vary on some intensifiers.
Check valve orientation of both the long-block and
short-block intensifiers is shown on the next page.
