Electric Motor Pump

Start by multiplying the rise in pressure by the volumetric flowrate, all expressed in compatible units. Then divide by the efficiency.

Alternatively, give the rise in pressure and the volumetric flowrate to several diesel-driven pump suppliers, and let them do the selection.

how much water was the pump/diesel engine producing before it broke? gallons per day or hour will do

I guess that you just want to fit a new motor to the pump you already have, Yes? If so then what is the pump size, not physical size, how much water can it produce (the flow rate), is it a centrifugal pump? do you know how many stages your pump has, if not,- does the pump have a label on it with lots of information? Having all that info off the label would really help. The things to look for, Make, Model and Model number, RPM, flow rate in either gallons or litres, maybe you could contact the manufacturer to get figures if you know the make and model.

Try get information on the diesel engine itself as a guide to HP. Torque may be a issue to contend with.

Guys, all your comments had helped me. I had arrive to 10HP, single phase, 230v, 60hz motor. Again, thanks a lot and Godbless

Another satisfied customer, didn't we do well??

i don't think that only an electric motor pump will do the job. 200 m is a big distance. i think you will need an electric engine (three phases) and a pump connected to the engine shaft. sorry, but you cannot compare an electric engine (1 phase) with a diesel engine. it is all about the power.but you don't have the power supply...so... you should repair the diesel engine.

May be you are right ion that electric engine is more reliable than an electric motor pump in this 200m elevation. But our problem is the availability of 3 phase power. We only have 1 phase 230V. Our diesel engine was overhauled twice already. One thing more very considerable is the cost of using diesel fuel compared to electric energy consumption. Using 10HP motor pump (if this could work on this elevation) we will just consume 37.3KWHr for 5hrs whivh could supply us water for one day which cost of 167.85 PHP. Kindly help me into this if what motor pump shud I use with 1 phase, 230V power supply.

Thanks and kind regards,

Carel

37,3 kWh in 5 hours? are you sure that your electrical installation support all this amount of power? you will need a fuse for minimum 35 A . your power cable must have a section of minimum 6 mm2. i searched the internet and i did not find an one phase electric pump with this consumption to do the job. anyway... i wish you good luck!
