15.3 MAINTENANCE SAMPLE GAS PUMP
Note
Detailed technical information on the sample gas pump can be found in the
MP-F05 instruction manual.
The instruction manual can be found at www.mc-techgroup.com
It is necessary to schedule maintenance work at least twice a year.
The intervals between servicing are dependent on the process and system conditions in your facility.
The facility QA/QC plan should address the frequency for maintenance and should be updated based
on your operations.
Danger
Follow all safety notes and descriptions stated in this manual.
There may be harmful sample gases in the pump. Prevent potentially
harmful gases from escaping the open sample gas lines during
maintenance. Purge the pump with inert gas or air before servicing.
Warning
High voltage!
Working without disconnecting the power supply may cause an electrical
shock. Disconnect power supply before any assembly, maintenance or
disassembly.
Secure the pump against accidental restart.
Aggressive condensate possible.
Chemical burns possible due to aggressive media!
For general electrical and mechanical work on the pump, wear personal
protective equipment (PPE) in accordance with the risk assessment.
The four hexagon socket screws, see Figure
9 part G, need to be re-tightened to a value of 5 Nm
[≈ 3.69 ft/lbs] by using a torque wrench. Start to re-tighten one screw. Tighten the opposite screw to the
same amount, then select the adjacent pair. Repeat in the same sequence to reach the value of 5 Nm
[≈ 3.69 ft/lbs].
The bellows and valve plates are the only consumable parts of the pump. The valve plates need to be
replaced, when they are < 1.6 mm [≈ 0.063”] thick. They are easy to replace.
