I think you should consult you pump curve and the rated head and flow for your pump. Then you should figure out possible piping layouts for your irrigation system and examine the hydraulics of those options and how they compare with the ratings from your pump. Then you can decided whether the...
I work for a water utility which predominantly supplies water to storage reservoirs via gravity flow, however, for about 10% of our systems we pump water from a tank at low elevation to a reservoir at a higher elevation. The pumps used are typically vertical multistage centrifugal pumps such as...
This is for a gravity flow water system in Dominica, the Caribbean's most mountainous island. The water must come from very high elevations, come down to sea level, travel along the coast and then go back up to various storage tanks at high elevation, thus the high pressures. At present, AWWA...
I recently requested quotations for very high pressure (~600 psi) gate valves for use with potable water. Most companies replied that they could not quote because their valves for these pressures did not have the protective epoxy coating in accordance with AWWA C550. I, however, received one...
Thanks for all the replies. I've since been able to source suitable valves due to your help. However, I still have one problem. All the valves I've seen so far come with a rising stem and handwheel. In the open position the wheel may rise to almost 5 feet, for the 10-inch valves for example...
I need to find a good supplier/manufacturer (price, quality, reliability) for gate valves with working pressures of up to about 800 psi for water supply. Thanks.
