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:

çH

hQq

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:

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.
