What is Pump A pump is a device that moves fluids

(liquids or gases) by mechanical action

Centrifugal Pumps Working Principal Centrifugal Pump work on centrifugal

Centrifugal Pump

11

Advantage Of Centrifugal Pump1. Its initial cost is low2. Efficiency is high.3. Discharge is uniform and continuous4. Installation and maintenance is easy

12

Disadvantage Of Centrifugal Pump1. 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 Pump1. Reciprocating pumps will deliver fluid at

high pressure (High Delivery Head).2. They are 'Self-priming' - No need to fill the

cylinders before starting.

17

Disadvantage Of Reciprocating Pump1. 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

18

Rotary pumpThese pumps move fluid using a rotating

mechanism that creates a vacuum that captures and draws in the liquid .

23

Advantage Of Rotary PumpRotary 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 Pump1. The cost of producing piston pumps is high2. They give low volume rates of flow

compared to other types of pump3. The suction stroke is difficult when pumping

viscous liquids.
