SPX Cooling Technologies TG MAG23-65 Instructions for start-up, General, Cleaning the pump

3.19 Instructions for start-up

3.19.1 General

The pump can be put into service when all arrangements described in chapter 3.18 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.

3.19.2 Cleaning the pump

There may be residual mineral oil inside the pump deriving from the pump testing and the initial lubri- cation of the bearing bushes. If these products are not acceptable for the pumped liquid, the pump should be cleaned thoroughly. Proceed as described in section 3.21.2.8 Draining of fluid.

3.19.2.1Cleaning suction line

Before the TG MAG pump is put into service for the first time, the suction line must be cleaned thoroughly. Do not use the TG MAG pump for flushing the system, because it is not meant to pump low viscous liquids which might contain particles.

3.19.3 Venting and filling

To operate properly the pump should be vented and filled with liquid to be pumped before initial start-up.

If the liquid level on the suction side is below the suction flange level of the pump the pump must be filled with liquid to make priming possible.

•Unscrew filling plugs Bb and Be. Fill up the pump with liquid to be pumped via connections Be.

•Rotate the pump shaft by hand in the normal sense of rotation while filling the liquid into the pump.

•Tighten the filling plugs Be. Screw in plug Bb but not tighten it.

•Start the pump and tighten plug Bb when all air has escaped and liquid starts flowing out of this connection.

2x Be Bb

Ba

If the liquid level at the suction side is above the suction flange level of the pump vent the pump as follows:

•Loosen filling plugs Bb and Be so that air can escape.

•Open the suction side valve to let the pumped liquid flow into the pump. Rotate the pump shaft by hand in the proper sense of rotation during venting.

•Tighten the plugs Bb and Be when liquid starts flowing out of these connections.

When the TG MAG pump is brought into service for the first time or in case a new gasket for the top cover was mounted, bolts that compress the gasket must be re-tighened again after 3 – 4 days. (for tightening torques: refer to section 3.21.3.1 Nuts and bolts)
