3.18 Instructions for start-up
3.18.1 General
The pump can be put into service when all arrangements described in chapter 3.17 Installation have
been made.
•
Prior to commissioning, responsible operators have to be fully informed on proper
operation of the pump/pump unit and the safety instructions. This instruction manual
must at all times be available to the personnel.
•
Prior to commissioning, the pump/pump unit must be checked for visible damage.
Damage or unexpected changes must be reported immediately to the plant operator.
3.18.2 Cleaning the pump
There may be residual mineral oil inside the pump deriving from the pump testing and the initially
lubricating of the bearing bushes. If these products are not acceptable for the pumped liquid, the
pump should be cleaned throughly. Proceed as described in section 3.20.2.8 Draining of fluid.
3.18.2.1 Cleaning suction line
When the TG BLOC pump is put into service for the first time, suction line must be cleaned
thoroughly.
Do not use the pump to flush the system. The TG BLOC pump is not meant to pump low viscosity
liquids with impurities.
3.18.3 Venting and filling
To operate properly the pump should be vented and filled with the liquid to be pumped before the
initial start-up:
•
Unscrew the filling plug Bb and Be. Fill up the pump with the liquid to be pumped.
At the same time the pump will be vented.
•
Tighten the filling plugs.
•
When the TG BLOC pump is brought into service for the first time or in case new gaskets are
mounted, bolts that compress gaskets must after 3 - 4 days be tightened again
(for tightening torques see section 3.20.3.1)
