OC9 - A Southern Cross 5" x 5" pump with a "story"!


This pump is testimony to the "smarts" of our previous generations!! Southern Cross designers were sufficiently switched-on operators to use the one gear box to power a number of different pumps - fewer "spares" needed to be produced and kept on-hand and mix-and-match at your leisure!! And this pump is hard evidence of that flexibility!!

This pump came to us as a 2.5" x 5" pump with a cracked wet end that was beyond repair. We had a "spare" 5" x 5" wet end that we just bolted on - so, so simple!!! Along the way, we added a new liner, new piston plates, a new centreplate and the obligatory wet-end maintenance kit and ... hey presto ... we "made" a new pump!!! Though it is not shown, the gearbox is in very sound condition.


These pumps have 2.5" suction and discharge. They will pump to a head of 250 feet and will deliver 2100 gallons per hour at 50 strokes per minute (or 250 rpm at the pump). The horsepower required for this is only 4 hp unless you need to speed up the pump (which is not highly recommended).
