OGEM SB CENTRIFUGAL PUMP
The energy created by the pumpis kinetic energy according the Bernoulli Equation. The energy transferred to the liquid corresponds to the velocity at the edge or vane tip of the impeller. The faster the impeller revolves or the bigger the impeller is the higher will the velocity of the liquid energy transferred to the liquid be. This is described by the Affinity Laws.
Pressure and Head of centrifugal pump
If the discharge of a centrifugal pump is pointed straight up into the air the fluid will pumped to a certain height - or head – called the shut off head. This maximum head is mainly determined by the outside diameter of the pump’s impeller and the speed of the rotating shaft. The head will change as the capacity of the pump is altered.
The kinetic energy of a liquid coming out of an impeller is obstructed by creating a resistancein the flow. The first resistance is created by the pump casing which catches the liquid and slows it down. When the liquid slows down the kinetic energy is converted to pressure energy.
it is the resistance to the pump’s flow that is read on a pressure gauge attached to the discharge line
A pump does not create pressure, it only creates flow. Pressure is a measurement of the resistance to flow.

In Newtonian fluids (non-viscous liquids like water or gasoline) the term headis used to measure the kinetic energy which a pump creates. Head is a measurement of the height of the liquid column the pump creates from the kinetic energy the pump gives to the liquid.
the main reason for using head instead of pressure to measure a centrifugal pump’s energy is that the pressure from a pump will change if the specific gravity (weight) of the liquid changes, but the head will not
The pump’s performance on any Newtonian fluid can always be described by using the term head.
Different Types of centrifugal Pump Head
Total Static Head - Total head when the pump is not running
Total Dynamic Head (Total System Head) – Total head when the pump is running
Static Suction Head – Head on the suction side, with pump off, if the head is higher than the pump impeller
Static Suction Lift – Head on the suction side, with pump off, if the head is lower than the pump impeller
Static Discharge Head – Head on discharge side of pump with the pump off
Dynamic Suction Head/Lift – Head on suction side of pump with pump on
Dynamic Discharge Head – Head on discharge side of pump with pump on
The head is measured in either feet or meters and can be converted to common units for pressure as psi or bar.
OGEM Centrifugal pump
it is important to understand that the pump will pump all fluids to the same height if the shaft is turning at the same rpm
The only difference between the fluids is the amount of power it takes to get the shaft to the proper rpm. The higher the specific gravity of the fluid the more power is required.
