The centrifugal pump is the most used pump type in the world. The principle
is simple, well-described and thoroughly tested, and the pump is robust, effective
and relatively inexpensive to produce. There is a wide range of variations
based on the principle of the centrifugal pump and consisting of the
same basic hydraulic parts. The majority of pumps produced by Grund fos are centrifugal pumps.

Principle of the centrifugal pump:

 An increase in the fluid pressure from the pump inlet to its outlet is created
when the pump is in operation. This pressure difference drives the fluid
through the system or plant.
The centrifugal pump creates an increase in pressure by transferring mechanical
energy from the motor to the fluid through the rotating impeller.
The fluid flows from the inlet to the impeller centre and out along its blades.
The centrifugal force hereby increases the fluid velocity and consequently
also the kinetic energy is transformed to pressure.

Different Types of 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

Typical Applications for Centrifugal Pumps:

Filling/draining
Cooling tower transfer
Filtration of corrosives, caustics, dyes, soaps, brines, and other cleaning fluids
Feed pumps for spraying systems
General fluid transfer
Line cleaning/irrigation
Pilot plant processing

Use a Centrifugal Pump:

1.Electric driven and suitable for continuous duty
2.Excellent pulse less flow
3.Fluid transfer at high flow rates, low pressure
4.Available in a range of materials

 Magnetic drive centrifugal pumps operate with a magnetic field that couples the impeller and motor together. There are no

shafts or seals connecting the impeller and motor. Therefore friction loss, wear, contamination and leakage caused by these

shafts and seals are eliminated.
        Mechanically coupled centrifugal pumps utilize a rotating impeller driven by a shaft with a seal that is connected to

the motor. They are often less expensive than magnetic drive and can achieve high flow-rates and pressures.
