Output pipe
When installing, prepare a trench from the pump to the holding tank. Specify a pipe with sufficient internal diameter to
optimise water flow and lay this pipe in the trench. Run the pump to ensure there are no punctures, or holes in the pipe
and then cover.
ZM–MAXXI
pumps can pump water horizontally up to 12,0000m (12km) or to an elevation of up to 300m (defined as
Water Column Meters), according to the model and the table no. 3 below. A combination of distance and height is possible
and advice in this regard is available from ZM Pompe
’s engineers .
Where the height from the pump and holding tank is greater than 70m, an extra wheel is recommended on the pump.
Also, as distance between pump and tank increases, it is recommended that the water pipe diameter be increased to
minimise pressure loss (see table No. 2).
Useful Recommendation
The use of a union at the exit of the pump and a non return valve near of the pump (within 2m) is strongly advised. In
situations where extended distance and heights are encountered, a non return valve is necessary for every 20m of water
head created.
