The ram pump has only two moving parts, the
valves, which makes it mechanically very simple and highly
reliable. It needs minimal maintenance and has a long lifespan
(see video 2). Video No.1 above is an animated explanation on how
a ram pump works including details of its advantages and disadvantages. Video No.2
shows a ram pump in operation and No.3 is part 1 of a
2 part explanation of the things you must consider in the
design and installation of a ram pump. It's a good idea to
check your calculations before building and installing your
pump. For a practical guide to the installation and operation
of a ram pump, as well as describing the operation and the factors
affecting its performance we (and the
Centre
for Alternative Technology) recommend the book
Hydraulic Ram Pumps (right). |
