Commissioning a mechanical seal skid
Commissioning a mechanical seal skid
(OP)
Hi
I am trying to find background information on commissioning a mechanical seal skid for a centrifugal pump. Vendor will perform start-up of system.
Medium in seal skid is meg/water. What checks should be done to verify the mechanical seal skid?
Check fluid fluid cleanliness? NAS/ISO standard?
Verify leakage rates? (DPM)
Other steps I may have missed?
Thanks

RE: Commissioning a mechanical seal skid
Is it the Barrier fluid make-up skid and what Flushing Plan are you using?
Basic checks are, inter face piping connection, cooling system, instrumentation function and settings, accumulator pre-charge pressure.
It all depends on how complex is your system.

Since First Star-up is related to Warranty issue is a new mechanical seals and pumps,and varies pump to pump.
-First step,
Contact Supplier, Vendor, Manufacturer for Warranty terms and star-up assistance.
-Second step
Gathering all data:
Mechanical seal drawing. Check type seal, manufacturer, conexions, etc.
API/ANSI Lubrication plan drawing and BOM.
Pump, coupling and driver data, if there is any previous performance, hydrostatic, vibration, etc test done by manufacturer, etc.
Motor/Pump/Mech seal operation, maintenance manuals.
-Third step.
Made a check list based on:
Vendor , supplier, manufacturer recommendations,
Standard availables like API610,676,682,RP686, ANSI or HI.
Internal check list or standar made by your own company.
Paper, i attached one published by Texas Pump simposium.
Pump type and services.
-Four step
Plan fist inspection, parameters expected on star-up(temperature, vibration, capacity, pressure, amperage, oil level, etc.
-Five step
Made a pre-commisioning check list and installation check list for main equipment and accesories before star up.
I hope it will help.

Pumpsonly, I will get the data sheets ans be more specific.
RE: Commissioning a mechanical seal skid
A bite late but the mechanical seal is:
API 682 Duel Pressurised FACE to FACE configuration
Flush Plan 53B
So my main question is about fluid and the cleanness of it as mentioned in the first post?
Thanks
