Choosing the correct number of React pumps for your site
2.3.4.
Different sites will need a different number of PowerSpout React pumps depending on the
head and daily volume you need to pump. It is not an economic option to manufacture many
different React pump size options. If you need more flow or more head all you need to do is
install another React pump.
More than one React pump greatly improves system reliability on parallel installations, as if
you do get an React pump failure (solar PV panels rarely fail as they have no moving parts),
then up to 1620W of the available solar PV can be attached to the remaining React pump
while the other unit is away being repaired.
Repairs when needed are simple and fast. You can either send it back by courier to
EcoInnovation (only NZ clients) or you can do it yourself by buying the parts you need
online.
With multiple pumps you could simply run the React pumps until one fails (but if you do this
make sure to check and top up oil level often) rather than having to take a more proactive
approach with annual maintenance checks.
With many water source combinations, 3 x PV array sizes, multiple React pumps, parallel
and series installations the React pump can solve almost any stock water pumping problem.
Once you have determined the head, use this chart and table to estimate your daily pumped
volume (for summer days) and the peak flow rate per turbine, for pipe sizing.
These estimates are based on performance measured at our test site in Taranaki NZ. We
regard this data as indicative of likely performance – you may pump more or less than this.
If for example you need 7,500 l/day in summer to a 100m tank you will need to install
one React pump with pipes rated for 12 bar.
If for example you need 15,000 l/day in summer to a 100m tank you will need to
install two React pumps in parallel with a larger pipe rated for 12 bar.
If for example you need 5,000 l/day in summer to a 200m tank you will need to install
one React pump with pipes rate for 20 bar.
If for example you need 6,000 l/day in summer to a 320m tank you will need to install
two React pumps in series with pipes rated for 16 bar.
If for example you need 5,000 l/day in summer to a 750m tank you will need to install
three React pumps in series with pipes rated for 25 bar.
