Routine Maintenance
Before performing any maintenance on your skid system or pump,
Routine maintenance will depend upon your service requirements: dosing chemical(s) being handled,
environmental conditions, duty cycle(s) of pump(s), etc. When working on any component of your
system, i.e., pump, valves, pulsation dampener, refer to the Installation, Operation and Maintenance
Manual for that particular item. Some operational and maintenance checks that need to be performed
are:
Strainer – A Y-strainer is furnished in the suction header for the skid. Check this for the presence of
trapped solids and clean as necessary. Recommend weekly check.
Piping/Tubing Integrity – Routinely check piping, tubing, isolation valves and connections for leaks.
Replace tubing as necessary. Recommend weekly check.
System Operation – Perform flow calibration regularly to ensure that dosing chemical is being added
at the proper rate. Recommend monthly.
Pressure Relief and Back Pressure Valves – Check to ensure that bolts are tight. Recommend
monthly. Diaphragms should be replaced on an annual basis.
Pulsation Dampener – Check air pressure versus recommended set point. Recommend weekly.
Calibration Column – If handling sticky chemicals, may require cleaning to view liquid level inside.
Perform as necessary.
!
WARNING
Skid components, pump(s) and your process piping may be under pressure!
Prior to working on any portion of the Skid System, disconnect pump(s) from
power supply, de-pressurize the entire system and drain chemicals from the lines.
Flush and neutralize as necessary.
Always wear suitable protection (gloves, safety glasses/goggles, etc.)
