What kind of DC pump will I require to discharge the water at sufficient pressure and high volume?

by Ahana Shrestha | Practical Action | 2017-01-09 21:39:44 -0500 | related country: Nigeria

I want to start potable water distribution enterprise using 1600 litre water bowsers drawn by 3-wheeler vehicles in unserved communities dispensed via 100 meter long hose to houses, including apartments on upper floors of multi-storey blocks. What kind of DC pump will I require to discharge the water at sufficient pressure and high volume. Will I need to couple the dc pump to a small pressure tank? Give type, ratings of pump and pressure tank, if necessary. The objective is quick discharge to locations at least 100 meter removed

Answer depends on pumping rate and pressure.

The headloss in the 100m hose will be minimal compared to the headloss from pumping to upperfloors (assuming you use a hose 40mm dia if pumping 50l/min). How many floors are we talking about? 10 floors is approx 30m or 3 bar

The 12v pumps here can used powered off the 3 wheeler's battery/generator. Which one depends on l/min and pressure head listed in specs which only you can answer although for small domestic distribution 50l/min at 50m pressure head or 5 bar will probably be sufficient
