Just remember that the pump does not do any pressure. So no sandfilters etc. I've got a .75kw pedrollo that delivers 46 000 litres per hour. The running cost on this pump is R530 per month:
.75kw x 24hours x 30days x units cost (VAT incl) 98c = R530 per month.
These pumps are high flow low pressure pumps. They are fine with around 1m head but not too many elbow etc..
Do you perhaps know how must water flow per hour will I loose on a Pedrollo with a 1.2m head height? I am planning to replace my 2 x 750W motors with a single motor that is capable to produce around 40kL/h. My filter is above ground level but the pump is only 2meters away from filter. I can get away with very few bends and I do not use a high pressure system.
