ROPV Pressure Vessels are designed to provide safe operation over a long service life
if properly installed, operated, and maintained. The vessel may cause loss of life,
severe bodily harm, or property damage if not correctly installed, operated, or
maintained. Read and understand all guidelines provided in the vessel User Manual.
Observe every precaution contained therein. Failure to do so may result in malfunction
and potential catastrophic failure. It is recommended that only qualified technicians
experienced in servicing hydraulic systems work with this vessel. Misuse, incorrect
assembly, or use of damaged/corroded components may result in catastrophic failure.
Vessel Use and Precautions
•Positive pressure up to the design pressure (PSI) of the specific model being
used.
•Accommodates standard 8” nominal diameter spiral-wound element.
•The required vessel/element interface hardware is supplied with the vessel.
Ensure that an element adapter is installed at each end of the vessel before use.
•Vessel expands under pressure and careful consideration must be taken when
installing straps/saddles and system connection piping.
•Installation with the straps/saddles provided is strongly recommended
•Vessel should not support any other system components. Connections should
be non-load bearing.
•Periodic inspection of the vessel end closure is recommended to ensure all parts
are dry and free of corrosion.
•Failure to understand and follow all precautions may void warranty and result in
catastrophic failure of the vessel.

ROPV R80 S Series Manual August 2005B
•These guidelines are subject to change. Please check with ROPV to ensure that
the User Manual is the latest version for the vessel model being used.
•Mount vessel using strap/saddle hardware provided and span recommended in
the engineering drawing.
•Do not over tighten the straps – vessel must be allowed to expand under
operation.
•Maximize the connection flexibility to allow for vessel growth under pressure.
•Align the side ports with the system manifold, correcting any misalignment before
final installation.
•Provide overpressure protection in the system safety devices.
•Inspect end closures regularly for signs of corrosion. Immediate corrective action
and/or replacement is suggested in case of corrosion.
•Relieve system pressure before working on the vessel.
•Do not attempt to over-tighten the Permeate Port connections as this may
damage the end closure. One turn past hand tight should be sufficient.
•Ensure that the Trust Cone is installed on the downstream end of the vessel.
•Never operate the vessel in excess of its ratings. This may void the warranty and
cause bodily or property damage.
•Do not operate the vessel permeate port over 125PSI.
•Flush the vessel with permeate before system shutdown to reduce the chance of
corrosion.
•Do not install the vessel in direct sunlight.
•Operate the vessel within the recommended pH range - Operating pH Range: 3 –
11, Cleaning pH Range: 2 – 12 (less than 30 minutes).

Head Removal
Step 1 Shut Down System and Relieve System Pressure – The system must be shut
down and all pressure relieved before conducting any maintenance or repair on the
vessel.
Step 2 Disconnect Permeate Piping – The system permeate piping must be carefully
removed from the permeate port of the vessel.
Step 3 Inspect End Closure – The end closure should be inspected for any signs of
corrosion or damage. Surface corrosion can be removed with a wire brush, while
flushing with water. Damaged components should be replaced with approved
components from ROPV.
Step 4 Disconnect Locking Screws – Each of the three locking segments is held in
place with a securing ring. The securing ring is held in place with 3 locking screws. The
locking screws can be removed using an M6 / 7/32” hex wrench. The locking screws
should be unthreaded from the head only, not from the locking segment. The locking
screw and locking segment can be removed together.
Step 5 Remove the Locking Segment/Screw Assemblies – The locking
segment/screw assemblies should be easily removed from the retaining groove. Should
the assemblies be difficult to remove, it may be necessary to rock the head slightly or
tap the head inward with a rubber mallet. Be careful when using metal tools, avoiding
leveraging against the sidewall of the vessel or scratching the inside surface of the bell
area.
Step 6 Remove the Head Assembly with One of the Following Techniques
ROPV Head Removal Tools – A set of head removal tools is available from ROPV.
While not necessary for head removal, they have proven an effective and easy way to
remove the vessel head without causing any damage to the vessel.

Picture 1 Picture 2 Picture 3
Picture 1 – Detail picture of head removal tools.
Picture 2 – Thread the center piece into the permeate port of the head assembly, to
hand tight. Do not over tighten the center piece.
Picture 3 – Position nut, bearing rod, and bearing block as shown. Turn bearing rod
clockwise. The head will move with the bearing rod as it moves toward the end of the
vessel. You will be able to remove the head once it has cleared the retaining groove
area of the vessel.
Alternative Head Removal – It is possible to remove the head assembly without the
ROPV head removal tools. A 1” NPT Male threaded piece of PVC (or similar material)
pipe should be threaded into the head permeate port to hand tightness. Pull the pipe
outward to remove the head. If the vessel has been in operation for an extended time,
a slight rocking motion or forceful tug may be required to break the head seal bond.
Also, a handle at the end of the pipe will ease head removal – forming a T with the pipe
that threads into the permeate port.

Head Disassembly and Inspection
Step 1 Remove the Head O-ring – Use a non-metallic, rounded tool to start the o-ring
out of the o-ring groove. Once a small portion of the o-ring has been lifted out of the
groove, use your hand to work the remainder of the o-ring out of the groove. Damaged
or cut o-rings must be replaced during re-installation of the head.
Step 2 Remove Adapter – Grasp the adapter slowly pull from the bearing
plate/permeate port. A slight rotating motion may ease the removal of the adapter.
There is a set of double o-rings on the inside diameter of the permeate port that must be
inspected for damage once the adapter is removed. Damaged o-rings must be
replaced before re-installation.
Step 3 Remove Bearing Plate – Use a wrench to remove the permeate port Locknut.
The locknut is reveres threaded (or left hand threaded) and must be turned clockwise to
be removed and counter clockwise to be installed. After removing the locknut, the
bearing plate and sealing plate can be separated.
Step 4 Clean All Components – All components should be cleaned with a mild soap

ROPV R80 S Series Manual August 2005B
solution or clean water. The components should be air dried or dried with a lint-free
towel.
Step 5 Inspect All Components – All components should be carefully inspected for
signs of corrosion and damage. Components exhibiting such should be replaced before
re-installation. All o-rings should be carefully inspected for signs of damage. It is
recommended that all o-rings be replaced during each complete servicing of the vessel.
Failure to do so may cause poor system performance.
Step 6 Inspect Inside Vessel Surface – The inside surface of the vessel should also
be inspected once the membrane elements have been removed. Special attention
should be paid to identify any scratches, damage or foreign matter. Surface scratches
can be repaired by carefully sanding the effected surface with 600-grit sandpaper. A
combination of soapy water and fresh water should be used to flush the area during
sanding. Clean water should be used to clean the area after sanding. Any
extemporaneous matter can be removed with a soft cloth, soapy water, and a clean
water flush. Damaged vessels should not be used under any circumstances.

Head Reassembly
Step 1 Inspect All Head Components – All head components should be free from
scratches, foreign matter, or any sign of damage. Please see Step 6 above for
additional information about cleaning head components. Scratched or damaged
components should be replaced with ROPV supplied replacement components. All o-
rings should be carefully inspected for signs of damage. It is recommended that all o-
rings be replaced during each complete servicing of the vessel. Failure to do so may
cause poor system performance.
Step 2 Install Permeate Port O-rings -All o-rings should be coated with a thin layer of
glycerine before installation. Care should be used to minimize the amount or glycerine
applied and any excess should be removed. Petroleum based lubricants should not be
used as they may cause membrane damage. Seat one o-ring into each of the two
grooves located on the inside diameter of the permeate port.
Step 3 Place Bearing Over Permeate Port/Sealing Plate
Step 4 Thread Lock Nut Onto Permeate Port – Lock nut should be tightened to hand-
tightness using a wrench for the final half-turn. Do not over tighten the Lock Nut –
maximum torque guideline: 15Nm. Note that the threads of the Permeate Port are
reverse or left-hand threaded.

ROPV R80 S Series Manual August 2005B
Step 5 Install Permeate Port and Adapter O-rings – All o-rings should be coated with
a thin layer of glycerine before installation. Seat one permeate port o-ring into each of
the two grooves located at the element end, outside diameter of the adapter.
Step 6 Install Adapter – The adapter should be pushed into the permeate port until the
wider diameter middle section is flush against the end of the permeate port.
Simultaneously pushing and turning the adapter will ease installation.
Step 7 Install Head O-ring – All o-rings should be coated with a thin layer of glycerine
before installation. Seat the head o-ring into the groove on the outside diameter of the
head.

Head Installation
Step 1 Follow All Steps Outlined in the Head Reassembly Section
Step 2 Install Head – Hold the head assembly with both hands, square to the axis of
the vessel. Push firmly with both hands until the head is correctly positioned and the
retaining groove is visible. It may be necessary to use a rubber mallet to tap the head
into its engaged position. The thrust cone must be installed with the head at the
downstream end of the vessel.
Step 3 Install Locking Kit Segments – Clean and dry the retaining groove. Position
the first two locking segments (No.1 and No.2 in picture) so that the end section sits in
the retaining groove. Position the third locking segment (No.3) into the last area.
Position the securing ring as shown and use an M6 / 7/32” hex wrench to tighten the
screw until snug. Do not over-tighten – maximum torque guideline: 10Nm. Install the
two other segments in the same manner. Conduct a final tightness check of each screw
after all three segments are installed.
Step 4 Reconnect Permeate Piping – Reconnect the system permeate piping to the
permeate port.
Step 5 Conduct Pre-Pressurization Inspection – A thorough pre-pressurization
inspection should be conducted, including verifying that the heads are properly installed,
system piping connections are in place, elements are installed, adapters are installed,
and thrust cone is installed at downstream end of the vessel.
