PUMP THEORY
Centrifugal Pumping Principles
Many hydraulic systems employ centrifugal pumps to move fluid through a piping system. These pumps all rely on centrifugal force as the fundamental principle by which they operate. Centrifugal force affects an object or material moving in a circular pattern by causing it to pull away from the central axis or center point of the path along which it travels. This force can be used to regulate the pressure and motion within a pumping unit, and when applied in combination with a number of other centrifugal pumping principles, forms an integral part of hydraulic mechanisms. Generally, a centrifugal pump is based around a casing filled with fluid, usually water. A special unit within the casing exerts fast rotary motion that causes the water to spin, generating centrifugal force that channels it through a discharge outlet. Discharged water creates a vacuum for atmospheric pressure to force more water out of the casing. It is a continuous process, dependant mostly on continued rotary motion and a constant supply of water. Most centrifugal pumps rely on rotating impellers or vanes to provide rotary motion, though the design and implementation of these systems can vary according to capacity and project requirements. Basic Centrifugal Pumping Concepts To better illustrate the essential principles of centrifugal pumping, it may be useful to consider a simplified version of an industrial pumping mechanism. A cylindrical can with a pair of rotary vanes along its interior can be attached to a shaft. This shaft has a pulley unit responsible for agitating the can with rotational movements. Once the can is filled with water, the pulley begins to rotate the shaft at high speed, causing the can to spin. As the water in the can rotates, centrifugal force pushes it out toward the walls of the can where it is pressed against the edges of its container.
Because the water cannot continue moving outward through the walls of the can, it begins to climb upward, eventually overflowing while the water at the center point is drawn downward. The overflowing water moves at the same velocity as it does at the rim, meaning that the kinetic energy it produces can be maintained if the water is caught and more water is supplied to the pump. Therefore, a receiving container is usually employed to catch the spilling water and a surplus tank is attached to the shaft to maintain a continuous supply of liquid. The same centrifugal force effect can be achieved without the pulley mechanism by rotating only the vanes or impellers within the can. Vane and Impeller Functions The radial vanes within a water casing cause the water to spin when the casing rotates or when the vanes themselves are rotated, making them crucial components in most centrifugal pumping systems. Likewise, the impeller is an integral pumping unit because it provides the rotational force that moves the vanes. Common types of vane and impeller designs include: • Straight Vane: In this basic configuration, water enters the casing through an inlet on the impeller. The impeller rotates its blades, causing the water to spin and generating centrifugal force that creates pressure along the impeller’s outer diameter. When enough force has been applied, the water pushes outward from the impeller and moves through a discharge channel at one end of the casing. • Curved Vane: This design features both curved vanes and a curved casing. An inlet pipe channels water toward the center, or “eye,” of the impeller unit, where curved vanes begin to push it toward the edge of the casing in a spiral pattern. As the rotary force continues to apply pressure, the water is directed into a discharge channel. • Volute: The volute is a single-plane spiraled curve that recedes from a central point. It is designed to match the shape of the casing surround the impeller in a centrifugal pump¸ and forms a passageway for discharged water. The volute expands at certain intervals, growing wider the further along the water flows.

Definition
Pump is a device that imparts energy to a fluid passing through it to enable the fluid to move from one point to another.
In practice, pumps change both the velocity and the pressure passing through them.

Types of Pumps
Marine Pumps fall into two broad classes:
28/11/09 9
Positive Displacement Pumps
Rotordynamic Pumps
Positive Displacement Pumps
28/11/09 10
Working Principles:
Fluid is displaced from the suction to the discharge by the
mechanical variation of the volume of chamber or chambers at every stroke or rotation of the pump
Volume of pump chamber alternately increases to draw the liquid
in from suction pipe & then decreased to force the liquid out into the delivery pipe This may be done by either a reciprocating motion of a piston or
by a rotary motion of specially designed vanes, gears or screws
Positive Displacement Pumps
Characteristic
28/11/09 11
Self-priming All the valves at the discharge side of the pumps must be
kept open prior starting
Failure to do so will cause rapid increase of fluid pressure,
leading to failure at the weakest point in the system
Relief valve is always fitted in the system to avoid such
failure
Positive Displacement Pumps
Subdivided into Two main categories:
28/11/09 12
Reciprocating Pumps
- where plunger or piston is reciprocated in a fluid cylinder - suitable for delivering small quantities at high pressure
Rotary Pumps ( Gear, Screw, Vane pumps ) - where the liquid is forced through the pump casing by means
of screws, gears or vanes - used for delivering moderate quantity at moderate pressure
Reciprocating Pump
Main Components
28/11/09 13
Cylinder
Piston
Piston rod
Gland
Suction valve
Discharge valve Pump may be of Single acting or Double acting type
Single Acting Reciprocating Pump
28/11/09 14
There is one suction & one discharge per cycle
Piston moves down during suction stroke
Causes low pressure to create & fluid to flow into cylinder by opening suction valve
Piston moves up during discharge stroke
Causes fluid to be compressed and pressurised
Discharge takes place by opening discharge v/v by high pressure fluid
SUCTION STROKE DISCH STROKE
28/11/09 15
There is two suction & two discharge per cycle
Piston moves from left to right (one stroke)
Piston compresses fluid above piston (discharge)
Piston draws fluid below piston (suction)
Double Acting Reciprocating Pump
Pressure Pulsation
28/11/09 16
Pressure pulsations are
inherent problem in reciprocating pump
It causes pipes to surge &
vibrate
Pipes may become loose
and break under heavy strain
Accumulators are used to
reduce the impact of pressure surges
Pressure St
AB C B C A
28/11/09 17
Accumulators are air vessels
or spring loaded device
Absorbs some energy during the pump discharge stroke
Releases this energy during low pressure period and raises the pressure in the pipe
Thus reduces the pressure pulsation by avoiding sharp drop in pressure
Accumulators Gear Pump
28/11/09 18
It is a positive displacement pump
It consists of two meshing gears with one driving the other
Fluid flows between the casing and the gear teeth
Commonly employed for lube & fuel oil transfer
Must have relief valve installed in the system
28/11/09 19
Screw pumps are positive displacement pumps
Screws are meshed together with one driving other
Fluid is displaced through the recesses between the screws and the casing
May have single, double or triple screws
Screw Pump
28/11/09 20
Vane pumps are positive displacement pumps
Rotors having slots for vanes
Centre of rotor is eccentric with casing
This causes vanes to move in and out as the rotor rotates
Causes change in volume in the respective chamber, similar to reciprocating pump
Vane Pump Rotodynamic Pumps
28/11/09 21
Often Known as dynamic pumps or centrifugal pumps
Centrifugal pumps are more suitable for delivery of large quantities at low discharge pressure
Are Non-self priming pumps
Looses suction and unable to pump once air gets into the pump system
Must be primed before starting
Used on ship as G.S. pump, Ballast Pump, S.W. & F.W. cooling pumps

Centrifugal Pump
28/11/09 23
Working Principle
Impeller rotates at high speed
Fluid enters through the ‘eye’ of the impeller
Fluid is thrown by centrifugal force from the centre (suction side) radially outwards to the periphery of impeller (discharge side)
High velocity fluid enters the stationary volute casing
Volute casing converts the kinetic energy of fluid into pressure energy at the discharge of the pump
Centrifugal Pump
Impeller Wear Ring
28/11/09 24
Located on the casing at the impeller suction
Must have clearance to allow rotation of impeller
If clearance is too small, wear ring may come in contact with impeller due to misalignment, expansion
If clearance is too big, fluid flows back to suction side
Cause drop in discharge pressure & pump efficiency

PUMP THEORY
Centrifugal Pumping Principles
Many hydraulic systems employ centrifugal pumps to move fluid through a piping system. These pumps all rely on centrifugal force as the fundamental principle by which they operate. Centrifugal force affects an object or material moving in a circular pattern by causing it to pull away from the central axis or center point of the path along which it travels. This force can be used to regulate the pressure and motion within a pumping unit, and when applied in combination with a number of other centrifugal pumping principles, forms an integral part of hydraulic mechanisms. Generally, a centrifugal pump is based around a casing filled with fluid, usually water. A special unit within the casing exerts fast rotary motion that causes the water to spin, generating centrifugal force that channels it through a discharge outlet. Discharged water creates a vacuum for atmospheric pressure to force more water out of the casing. It is a continuous process, dependant mostly on continued rotary motion and a constant supply of water. Most centrifugal pumps rely on rotating impellers or vanes to provide rotary motion, though the design and implementation of these systems can vary according to capacity and project requirements. Basic Centrifugal Pumping Concepts To better illustrate the essential principles of centrifugal pumping, it may be useful to consider a simplified version of an industrial pumping mechanism. A cylindrical can with a pair of rotary vanes along its interior can be attached to a shaft. This shaft has a pulley unit responsible for agitating the can with rotational movements. Once the can is filled with water, the pulley begins to rotate the shaft at high speed, causing the can to spin. As the water in the can rotates, centrifugal force pushes it out toward the walls of the can where it is pressed against the edges of its container.
Because the water cannot continue moving outward through the walls of the can, it begins to climb upward, eventually overflowing while the water at the center point is drawn downward. The overflowing water moves at the same velocity as it does at the rim, meaning that the kinetic energy it produces can be maintained if the water is caught and more water is supplied to the pump. Therefore, a receiving container is usually employed to catch the spilling water and a surplus tank is attached to the shaft to maintain a continuous supply of liquid. The same centrifugal force effect can be achieved without the pulley mechanism by rotating only the vanes or impellers within the can. Vane and Impeller Functions The radial vanes within a water casing cause the water to spin when the casing rotates or when the vanes themselves are rotated, making them crucial components in most centrifugal pumping systems. Likewise, the impeller is an integral pumping unit because it provides the rotational force that moves the vanes. Common types of vane and impeller designs include: • Straight Vane: In this basic configuration, water enters the casing through an inlet on the impeller. The impeller rotates its blades, causing the water to spin and generating centrifugal force that creates pressure along the impeller’s outer diameter. When enough force has been applied, the water pushes outward from the impeller and moves through a discharge channel at one end of the casing. • Curved Vane: This design features both curved vanes and a curved casing. An inlet pipe channels water toward the center, or “eye,” of the impeller unit, where curved vanes begin to push it toward the edge of the casing in a spiral pattern. As the rotary force continues to apply pressure, the water is directed into a discharge channel. • Volute: The volute is a single-plane spiraled curve that recedes from a central point. It is designed to match the shape of the casing surround the impeller in a centrifugal pump¸ and forms a passageway for discharged water. The volute expands at certain intervals, growing wider the further along the water flows.

Definition
Pump is a device that imparts energy to a fluid passing through it to enable the fluid to move from one point to another.
In practice, pumps change both the velocity and the pressure passing through them.

Types of Pumps
Marine Pumps fall into two broad classes:
28/11/09 9
Positive Displacement Pumps
Rotordynamic Pumps
Positive Displacement Pumps
28/11/09 10
Working Principles:
Fluid is displaced from the suction to the discharge by the
mechanical variation of the volume of chamber or chambers at every stroke or rotation of the pump
Volume of pump chamber alternately increases to draw the liquid
in from suction pipe & then decreased to force the liquid out into the delivery pipe This may be done by either a reciprocating motion of a piston or
by a rotary motion of specially designed vanes, gears or screws
Positive Displacement Pumps
Characteristic
28/11/09 11
Self-priming All the valves at the discharge side of the pumps must be
kept open prior starting
Failure to do so will cause rapid increase of fluid pressure,
leading to failure at the weakest point in the system
Relief valve is always fitted in the system to avoid such
failure
Positive Displacement Pumps
Subdivided into Two main categories:
28/11/09 12
Reciprocating Pumps
- where plunger or piston is reciprocated in a fluid cylinder - suitable for delivering small quantities at high pressure
Rotary Pumps ( Gear, Screw, Vane pumps ) - where the liquid is forced through the pump casing by means
of screws, gears or vanes - used for delivering moderate quantity at moderate pressure
Reciprocating Pump
Main Components
28/11/09 13
Cylinder
Piston
Piston rod
Gland
Suction valve
Discharge valve Pump may be of Single acting or Double acting type
Single Acting Reciprocating Pump
28/11/09 14
There is one suction & one discharge per cycle
Piston moves down during suction stroke
Causes low pressure to create & fluid to flow into cylinder by opening suction valve
Piston moves up during discharge stroke
Causes fluid to be compressed and pressurised
Discharge takes place by opening discharge v/v by high pressure fluid
SUCTION STROKE DISCH STROKE
28/11/09 15
There is two suction & two discharge per cycle
Piston moves from left to right (one stroke)
Piston compresses fluid above piston (discharge)
Piston draws fluid below piston (suction)
Double Acting Reciprocating Pump
Pressure Pulsation
28/11/09 16
Pressure pulsations are
inherent problem in reciprocating pump
It causes pipes to surge &
vibrate
Pipes may become loose
and break under heavy strain
Accumulators are used to
reduce the impact of pressure surges
Pressure St
AB C B C A
28/11/09 17
Accumulators are air vessels
or spring loaded device
Absorbs some energy during the pump discharge stroke
Releases this energy during low pressure period and raises the pressure in the pipe
Thus reduces the pressure pulsation by avoiding sharp drop in pressure
Accumulators Gear Pump
28/11/09 18
It is a positive displacement pump
It consists of two meshing gears with one driving the other
Fluid flows between the casing and the gear teeth
Commonly employed for lube & fuel oil transfer
Must have relief valve installed in the system
28/11/09 19
Screw pumps are positive displacement pumps
Screws are meshed together with one driving other
Fluid is displaced through the recesses between the screws and the casing
May have single, double or triple screws
Screw Pump
28/11/09 20
Vane pumps are positive displacement pumps
Rotors having slots for vanes
Centre of rotor is eccentric with casing
This causes vanes to move in and out as the rotor rotates
Causes change in volume in the respective chamber, similar to reciprocating pump
Vane Pump Rotodynamic Pumps
28/11/09 21
Often Known as dynamic pumps or centrifugal pumps
Centrifugal pumps are more suitable for delivery of large quantities at low discharge pressure
Are Non-self priming pumps
Looses suction and unable to pump once air gets into the pump system
Must be primed before starting
Used on ship as G.S. pump, Ballast Pump, S.W. & F.W. cooling pumps
Centrifugal Pump
28/11/09 22
Main Components
Impeller
Impeller wear ring
Volute Casing
Shaft
Ball bearing
Gland
Centrifugal Pump
28/11/09 23
Working Principle
Impeller rotates at high speed
Fluid enters through the ‘eye’ of the impeller
Fluid is thrown by centrifugal force from the centre (suction side) radially outwards to the periphery of impeller (discharge side)
High velocity fluid enters the stationary volute casing
Volute casing converts the kinetic energy of fluid into pressure energy at the discharge of the pump
Centrifugal Pump
Impeller Wear Ring
28/11/09 24
Located on the casing at the impeller suction
Must have clearance to allow rotation of impeller
If clearance is too small, wear ring may come in contact with impeller due to misalignment, expansion
If clearance is too big, fluid flows back to suction side
Cause drop in discharge pressure & pump efficiency
Centrifugal Pump

/hr), as a function of the head developed by the pump, given in terms of meters liquid column (mIc). This curve is called thepump characteristic. Curve A shows the pump capacity, given in terms of flow rate (normally M
28/11/09 26
Curve B shows the Net
Positive Suction Head (NPSH) requirement for the pump as a function of flow rate.The NPSH
-
requirement at any flow rate is the positive head of fluid required at the pump suction over and above the cargo's vapour pressure to prevent cavitation at the impeller.

Set the Pump on a level, solid foun-
1. dation in the lowest area of the tank, sump, or receptacle where liquid level is no less than 3” above the suction inlet of the Pump. Never operate the Pump on earth, clay, sand, or gravel surfaces. (See Figure A, ex page.) Avoid installation in areas of extreme 2. heat or cold. IMPORTANT: Never suspend the 3. Pump from its Power Cord (1) or discharge hose. You may rmly attach a rope to the Carrying Handle of the Pump.(See Figure A.) Connect a 2” diameter hose (not in4. cluded) rmly onto the 90° Elbow (32) of the Pump.(See Figure A.) Route the hose to the desired dis5. charge area. The hose should be kept as short as possible with a minimum number of turns. Additional plastic 90° elbows should be used if necessary to prevent hose kinking. nOtE:Themaximum delivery height of the Pump is 32 feet.
If the hose you install runs in excess 6. of ten feet, it is recommended you use a check valve (not included) to prevent back ow, which could lead to rapid cycling. To avoid air locks in the Pump, drill a 3/16” diameter hole in the hose, between the check valve and the Pump.(See Figure A.) If you choose to assemble and use 7. the Pump in a continuous run mode (without the Float Switch (20) attached) the Pump will turn on immediately when its Power Cord (1) is plugged into a 115 volt, grounded, electrical outlet. To turn off the Pump, unplug its Power Cord from its electrical outlet.do o allow he Pump o ru ry. (See Figure A.) If you choose to assemble and use 8. the Pump in an automatic on/off mode (with the Float Switch (20) attached), the Pump will turn on only when the level of waste water reaches the height - adjustable Float Switch.
