SPX FLOW Johnson pump - Preparations for Start-up

20 Installation and preparation start-up KGE/EN (1711) 6.5
Do the same check, but now on either coupling side, near the shaft. For safety sake,
repeat the check, using an outside caliper (B) at 2 diametrically opposed points on the
half coupling side faces.
3.6 Preparations start-up
Take the following precautions:
• Before commissioning the pump, remove any preservatives and flush the pump with
hot water.
• Check whether the seal chamber is filled with oil. If not, fill with lubricant.
 Never allow the seal to run dry !
• Check whether the pump shaft turns freely. Do this by turning the shaft end a few
times by hand.
• Fill the pump with water or the liquid to be handled through the filling plug on top of
the pump until the liquid starts to over flow.
