Maintenance

General Maintenance

The CFCS Skid System requires very little maintenance. However, the pump and all accessories should be checked weekly to ensure proper pump and skid performance. This is especially important when pumping chemicals that may be extra corrosive. Inspect all components for signs of unusual wear, clogging, leaking, swelling, cracking, discoloration, or corrosion. Ensure pump components are moving freely and not straining or excessively noisy. Replace worn or damaged components immediately. 

Monthly – Check for leaks. Clean any moisture and dirt. Tighten unions and hardware. Inspect skid system for corrosion. 

Yearly – Inspect tubing, connections, and elastomers. Replace, as needed. Thoroughly clean and replace any corroded hardware. Inspect all wiring and wiring connections. 

Inspecting and Replacing Accessories

The CFCS Skid System is provided with several accessory components. Each component may require separate maintenance based on the original manufacturer’s recommendations.  Check the documentation provided with the skid system for proper use and maintenance on these items: 

1. Ball Valves – Periodically check for leaks or deteriorating O-rings.   
2. Check Valve – Check valve seats may become worn or deteriorate over time. Check yearly or if you suspect any solution bypass. Replace the check as needed.  
3. Strainer – Depending on the solution’s condition, clean the strainer monthly or as frequently as required. Chemical tanks with particulate matter will require more frequent cleaning. 
4. Pulsation Dampener – Pulsation dampeners should be checked for proper charge once a month, or if the system is not performing properly. A properly charged pulsation dampener will extend the life of your pump and system components (See below).  Also, Periodic replacement of the bladder may be required.  
5. Pressure Gauge –  Check for accuracy monthly. Replace when showing signs of inaccurate readings.  
6. Flow Indicator – Check for proper movement. Clean periodically. 
7. Calibration Column – Clean as necessary to ensure accurate visual identification.

Charging the Pulsation Dampener

The pulsation dampener may require initial and periodic charging to maintain effectiveness. Refer to dampener manual for detailed instructions for charging.  

To charge the dampener:  

1. Determine the maximum actual operating pump system discharge pressure.  
2. Adjust pressurized air output pressure to a setting at/about pump system pressure. Do Not Use Oxygen.  
3. Remove cap from top of dampener air connection.  
4. Connect pressurized air line to the top connector of the dampener.  
5. Adjust valve to introduce air into dampener.  
6. Watch pressure gauge on dampener and close air valve when pressure reaches approximately 80-85% of system pressure.  
7. Close valve and remove air line from dampener.  
8. Once system pressure is in contact with the bladder/bellows, the gas charge will be compressed to the system pressure and the dampener gauge will read the system pressure, not the initial charge pressure.

Pressure Relief Valve Maintenance  

The pressure relief valve (PRV) provided with the skid will periodically require maintenance due to fouling and diaphragm or spring fatigue. Order KIT-PRV (diaphragm and spring) for this service.  

To service the Pressure Relief Valve (PRV):  

1. Relieve all pressure for skid system and flush as necessary.  
2. Remove pressure relief valve from the skid.  
3. Remove the black cap from adjustment stem.  
4. Note depth of set screw with a marker on screwdriver or removal tool.  
5. Remove set screw with flat head screwdriver or similar tool.  
6. Unscrew four bottom screws with 5/32” allen wrench.  
7. Remove the top portion on the valve.  
8. Remove the spring, backing piece, and diaphragm.  
9. Clean the valve seat and all internal surfaces with clean cloth.  
10. Inspect valve seat for wear or corrosion.  
11. Install the new diaphragm with PTFE (white) side down.  
12. Install the support disc and new spring.  
13. Place the top portion of valve back in place, and install/screw the set-screw to keep the spring from coming out.  
14. Install screws and hand tighten evenly.  
15. Then tighten the four screws to 3 ft-lbs torque.  
16. Return set screw to previous setting.  
17. Install the pressure relief valve in to the skid.  
18. Tighten union nuts, and pressure test valve to ensure proper setting.
