Waterfall Pump Sizing
Continuous operation of these
pumps in a pond or waterfall requires that the pump be sized for each specific
installation. Centrifugal pumps last longer and use less electricity when
operated in the mid-range of their performance curve (see chart below).
To calculate this, measure the height in feet from the surface of the pond
water to the point where the water returns to the pond (perhaps a waterfall
spillway). Add one (1) foot for every 90 degree elbow through which the
water passes from the pump to the point of return. Add one (1) foot for
every ten (10) foot length of tubing. This will provide the total height
that the pump must move the water. Locate that height in feet on the vertical
axis of the chart below and read to he right until you intersect the line
that represents the pump you would like to purchase. It is best to operate
the pump in the head height shown by the green area. If the lines intersect
too far to the left of the graph you must choose a larger pump. If they
intersect too far to he right you may either choose a smaller pump or install
a ball valve at the discharge of the pump. By
slightly closing the ball valve, never more than one third, you will create
additional back-pressure on the pump that will allow it to operate correctly
in the mid-range of its performance curve. Proper sizing of the pump to
your specific installation will ensure optimal performance and maximum
pump life.
