PERFORMANCE
The performance of a ram pump is determined by the working head “h” and the
manometric delivery height “H” to which water must be raised. Available flow rate is
usually equal to feeding flow rate “Q” of the pump. Pumped flow rate “q” can be
determined as follows:
ç
H
h
Qq 
where Q is the feeding flow rate in litres / minute
h is given in meters
H is given in Meters
h is the pump efficiency in %/100.
Example: let Q = 100 Litres / minute, h = 1.1 m, H = 9.0 m an h = 0.6. Therefore:

2. Then: Q = 100 x 1.1 / 9.0 x 0.6 = 7.33 litres / minute. = 10.56 m3/day
Working head “h” for our ram pumps can be as low as 0.5 m, but not higher than 15 m.
Flow rate capacity and maximal delivery height can be read from Table 1
Efficiency of our pumps may be adjusted to optimize performance and reach values from
50% to more than 80%.

TO SELECT A PUMP AND TO PLACE AN ORDER
Each ram pump is “tailored” in our workshop in accordance with specific
parameters of individual projects. Customer should indicate:
- the working head,
- the delivery head,
- the distance from pump to delivery site
- and total daily volume of water to be pumped.
