The document summarizes a seminar presentation on hydraulic ram pumps. It begins by defining a hydraulic ram pump as a cyclic water pump powered by hydropower that takes in water at one pressure and flow rate and outputs it at a higher pressure and lower flow rate, requiring no external power source other than flowing water. It then describes the basic components of a hydraulic ram pump as an inlet drive pipe, waste valve, outlet delivery pipe, and two check valves. The working principle is explained as water flowing through the drive pipe and forcing the waste valve closed, creating pressure to open the delivery valve and force some water up the delivery pipe to a higher elevation.

2. WHAT IS HYDRAULIC RAM ?
 A hydraulic ram is a cyclic water pump powered by
hydropower.
 It takes in water at one "hydraulic head" (pressure)
and flow rate, and outputs water at a higher
hydraulic head and lower flow rate.
 It requires no outside source of power other than
the kinetic energy of flowing water.

3. DESCRIPTION OF PARTS:-
A hydraulic ram has only two moving parts, a
spring or weight loaded "waste" valve sometimes
known as the "clack" valve and a "delivery" check
valve, making it cheap to build, easy to maintain,
and very reliable.
 there is a drive pipe supplying water from an
elevated source, and a delivery pipe, taking a
portion of the water that comes through the drive
pipe to an elevation higher than the source.

6. BASIC COMPONENTS OF A HYDRAULIC
RAM PUMP:-
1. Inlet — drive pipe
2. Free flow at waste valve
3. Outlet — delivery pipe
4. Waste valve
5. Delivery check valve
6. Pressure vessel

7. Initially, the waste valve [4] is open, and the
delivery valve [5] is closed.
 The water in the drive pipe [1] starts to flow under
the force of gravity and picks up speed and kinetic
energy until it forces the waste valve closed.
The momentum of the water flow in the supply pipe
against the closed waste valve causes a water
hammer that raises the pressure in the pump, opens
the delivery valve [5], and forces some water to flow
into the delivery pipe [3].

8. This water is being forced uphill through the
delivery pipe farther than it is falling downhill from
the source, the flow slows; when the flow reverses,
the delivery check valve closes.
If all water flow has stopped, the loaded waste
valve reopens against the now static head, which
allows the process to begin again
A pressure vessel [6] containing air cushions the
hydraulic pressure shock when the waste valve
closes, and it also improves the pumping efficiency
by allowing a more constant flow through the
delivery pipe.

10. CHARACTERISTICS OF HYDRAULIC
RAM :-
 No other external energy input .
 Its operation will continue 24 hours a day.
 Only a small portion of water will pump up.

11. ADVANTAGES AND LIMITATIONS OF
HYDRAULIC RAM PUMPS:-
Use of a renewable energy source ensuring
low running cost
little environmental impact
low maintenance requirement
Limited in hilly areas
Volumetric efficiency is very low
