Hydraulic Ram PumpTable 3 can now be used to select a ram size. The volume of driving water or supply needed is 20.5 litersper minute. From Table 4, a No. 2 Hydram requires from 12 to 25 liters per minute. A No. 2 Hydram canlift water to a maximum height of 250m according to Table 4. This will be adequate since the lift to the topof the storage tank is 23m. Thus, a No. 2 Hydram would be selected.Table 3 shows that for a No. 2 Hydram, the minimum drive pipe diameter is 38mm. Table 2 indicates thatthe minimum and maximum length for a 40mm pipe (the closest size to 38mm) is 6m-40m. Since thespring is 35m away, the length is all right. Table 5 can be used to select a delivery pipe 30mm in diameterwhich fits the supply needed, 20.5 liters per minute.This document is not copyrighted, so you are free to print and distribute it.
