ECO pumps head

Optimal use of the pumps:

Eco pumps head is indicated on above diagram. Follow f. ex. the graph for Eco 14000

(orange): at a head of 1 m, the pump yields about 12000 litre pr. hour.

If you follow the same pump to a head of 2,5 m, the diagram shows that the flow is

now only 8000 litre pr. hour, meaning that the performance reduces gradually accord-

ing to the lifting height.

Use always the biggest possible hose or pipe diameter, as this will ensure a low friction

and avoid sharp angles or bends, so that you will get the optimal pump performance.

If you connect a surface skimmer, the flow will bed reduced a little, as the pump now

also has to suck and it is important to use the biggest possible hose diameter to reduce

friction.

Also a surface skimmer with pre-filter can be connected, but that requires the installa-

tion of an adjustable Y-distributor in the pond, so that you can adjust between the suc-

tion from the skimmer and the suction from the pre-filter or low water filter.
