pump selection for irrigation system
pump selection for irrigation system
(OP)
I need help selecting a pump for a unique and demanding irrigation application. Here are the requirements:
-> 1-4 litres per minute (0.25-1 gpm)
-> 6-7m of head (19-23ft)
-> 6-24V DC solar powered
-> high efficiency
-> 20,000hrs or greater mean time between failure
-> low maintenance requirements
Submerged pumps are fine, suction pumps are fine, centrifugal, positive displacement, etc. are all fine, I just need something that can meet these requirements. If the pump is a suction pump or positive displacement, the head requirement can be reduced, but it will be lifting the water instead.
Thanks for your help.

but it has been discontinued and the replacement pump (DDC3.2) does not have sufficient head. Short of running two DDC3.2 in series and doubling the cost, I am out of options.

That is a lot of head. I don't know where to go for a PD that is that small and doesn't cost a fortune.
