3. What is Pump
 A pump is a device that moves fluids (liquids or gases)
by mechanical action

4. Where we use pump
 Factory
 Office
 Home
 Power Plant
 Industry
 School/Collage

11. Advantage Of Centrifugal Pump
 1. Its initial cost is low
 2. Efficiency is high.
 3. Discharge is uniform and continuous
 4. Installation and maintenance is easy
11

12. Disadvantage Of Centrifugal Pump
1. Extra priming requires.
2. Cannot be able to work high head.
3. Cannot deal with high viscous fluid.

13. Reciprocating Pump
 Reciprocating pumps move the fluid using one or
more oscillating pistons, plungers, or membranes
(diaphragms), while valves restrict fluid motion to the
desired direction.

16. Advantage Of Reciprocating Pump
1. Reciprocating pumps will deliver fluid at high
pressure (High Delivery Head).
2. They are 'Self-priming' - No need to fill the cylinders
before starting.
16

17. Disadvantage Of Reciprocating
Pump
1. They give low volume rates of flow compared to
other types of pump.
2. Reciprocating pumps give a pulsating flow.
3. The suction stroke is difficult when pumping viscous
liquids.
4. The cost of producing piston pumps is high
17

18. Rotary pump
 These pumps move fluid using a rotating mechanism
that creates a vacuum that captures and draws in the
liquid .

23. Advantage Of Rotary Pump
 Rotary pumps are very efficient because they naturally
remove air from the lines, eliminating the need to
bleed the air from the lines manually.

24. Disadvantage Of Rotary Pump
1. The cost of producing piston pumps is high
2. They give low volume rates of flow compared to
other types of pump
3. The suction stroke is difficult when pumping viscous
liquids.

flow

27. Pump Efficiency
Volumetric Efficiency:
η = Actual flow rate = Qa
Theoretical flow rate Qt
Gear pumps = 80-90 %
Vane pumps = 82-92 %
Piston pumps = 90-98 %
Mechanical Efficiency:
η = Output power = Po
Input power Pi
Mechanical efficiency varies from 90 to 95 %
Overall Efficiency:
η = Actual power delivered by the pump = Hydraulic power
Actual power delivered to the pump Brake power
