PUMPING PLANTS 
HINTS WHEN ORDERING 
Stockowners when writing engineering firms for 
quotations for pumping plants very often fail to give 
the essential information which will enable the 
engineers to quote right away. It should be borne 
in mind that both the type and size of Pumping 
Plants depend entirely onthe conditions under which 
the plant is to operate, and before an engineer can 
give any advice or quotations he must first have the 
following information :— 
A. 
B. 
с. 
Number of gallons required per day or hour. 
Whether water is to be pumped from well, 
dam or stream. 
Depth of water. 
If well, vertical height from water level to 
ground surface. 
If stream ог dam, vertical height from water 
level to place where pump can be installed 
and total length of suction pipe from water 
to pump. 
Vertical height from pump to top of tank ог, 
point where water is.to be delivered and. 
total length of delivery pipe required.: 
If possible, give sketch of well or stream 
showing position of pump—and lay of: 
pipe from water to point of delivery. 
This will enable the engineer to estimate the plant. 
complete, including all bends, etc. ' T
