Estimates and Prices
Will be given on receipt of the following particulars :
1st.—The fall (in feet or inches), which can be obtained from the stream, lake, or other
source of supply.
2nd.—The height to which the water is to be forced above the level of the Hydram.
3rd.—The distance to which the water has to be forced.
4th.—The approximate quantity of water (in pints or gallons) falling per minute.
5th.—The number of gallons required to be raised per day of 24 hours.
6th.—The distance in which the working fall is obtained.
7th.— If a “ B ” Hydram be required, the depth and horizontal distance from the
Hydram to the clean water should be stated, unless the clean water will
gravitate to the level of the Hydram.
“A” HYDRAMS raise part of the same water that works them.
“ B ” HYDRAMS work with impure water, whilst raising pure water from aspring or
shallow well.
Additional Particulars required in cases where Hydrams are required
to replace Unsatisfactory Rams by other makers.
A large proportion of the Hydrams we supply are to replace Rams by other makers
which are not satisfactory, and which have been put in in the first place on account
of their low price.
In such a case we require the following information :—
1st.—The length and bore of the existing drive-pipe, and how long in use.
2nd.—The length and bore of the rising main, and how long in use.
In taking the working fall on an old Hydram it should be measured from the surface
of the water over the mouth of the drive pipe, to the escape outlet of the waste or “ pulse ”
valve of the Hydram.
We cannot quote Prices without first having the information asked for above.
Would-be purchasers are often surprised that our Catalogue does not give any
Prices, but it is almost impossible to do so.
The cost of a Hydram depends on at least four things, which are never the same in
two cases consecutively, that is on the working fall and quantity of driving water
available, height to force, and amount of water to be raised, and therefore it is next
to impossible to quote even approximate prices without at least having answers to
the questions Nos. 1, 2, and 5 above.
Inclusive Prices quoted for the Hydram with its drive and delivery pipes delivered
and fixed, including tanks, service pipes and fittings, cattle troughs, and drinking bowls.
