2. WHAT IS THE PUMP?
• The pump is a mechanical device which conveys Liquid from one
place to another place.
• It can be defined as a hydraulic machines which Converts the
mechanical energy into hydraulicEnergy.
• The purpose of pump may be increasing the pressure ,they are
used for various applications in various filed.

4. TERMINOLOGY OF PUMPS
(1)Head: In the pumps, different forms of energy are expressed in terms of height which
is called ‘head’.
(2)Suction Head: It is the vertical height of the centre line of pump shaft above the
liquid.
(3)Delivery Head: its measured from centre line of pump shaft to where the liquid is
delivered.
(4)Velocity Head: which delivered liquid to end.
(5)Static Head: It is sum of suction and delivery heads.
hst= hs + hd

5. (6)Water Power: It is the power required by pump to handle the liquid to
develop manometric head.
Pw = ρgQHm
(7)Shaft Power: It is the power input to shaft of the pump by motor.
(8)Efficiency of pump: It is the ratio of water power To shaft power.

6. RECIPROCATING PUMP
• Pumps are used to increase the energy level of water by virtue of
which it can be raised to a higher level.
• Reciprocating pumps are positive displacement pump, i.e.
initially, a small quantity of liquid is taken into a chamber and is
physically displaced and forced out with pressure by a moving
mechanical elements.
• The use of reciprocating pumps is being limited these days and
being replaced by centrifugal pumps.

7. • According to use of piston sides
– Single acting Reciprocating Pump: If there is only one suction
and one delivery pipe and the liquid is filled only on one side of the
piston, it is called a single-acting reciprocating pump.
–Double acting Reciprocating Pump: A double-acting reciprocating
pump has two suction and two delivery pipes, Liquid is receiving on
both sides of the piston in the cylinder and is delivered into the
respective delivery pipes.
