IRRIGATION PUMP REMOVAL

 We are in the process of replacing our irrigation pumps that are used to pump water throughout the entire golf course.  The current pumps that are being replaced have over 16,000 hours on them and are performing at an insufficient level.  Meaning they are pumping a sufficient amount of water to the course but at a lower pressure.  This loss of pressure results in reduced coverage with each individual irrigation head and eventually weaker turf during the hot and dry summer months.  Here are some pictures of the pumps being removed from the pump house.

To take out the pumps we had to remove all the bolts and disconnect the wiring.  These are both 40 hp pumps that can pump out 800 gpm combined! 



From here the pumps were removed by crane throughout the top of the building.  This is the portion of the roof that was removed to allow this to happen.

This is one of the motors being lifted out of the pump house.

The next few pics are of the pumps and shafts being removed from the wet well, notice the darker areas where the rust and scale are built up.  Under these chunks of rust the metal is really soft and brittle, that is what sulfer will do over time.

This is the screen at the bottom of the pumps.  The bottom was brittle enough that when lowered onto the flat-bed truck it nearly broke off!



With the shaft being worn out, sand and sediment were able to be moved up the column through the pumps.  This increases wear and can cause problems out in the field.  Clogged foot valves and worn out drives to name a few.  Here are a couple pics of the sediment that came through and pictures of the pumps on the bed of the truck.

From here, the next step is to clean out the wet-well and have the new pumps installed.  I will have another post with pictures to follow in the near future. 

Hope to see many of you on the course!
