Principle of Operation
In Alfa Laval centrifugal pumps and multi-stage designs, fluid first enters through the impeller eye. It is then forced into a circular movement by rotating impeller vanes. These rotating impeller vanes transfer mechanical work to the fluid in the impeller channel. The fluid is then pressed out of the impeller by formed centrifugal force and finally leaves the impeller channel with increased pressure and velocity. The velocity of the fluid is also partly converted into pressure by the pump casing before it leaves the pump through the outlet.

Principle of Operation
Alfa Laval Rotary Lobe Pumps are conventional in design and operation. There are no internal contacting parts in the pump head. The rotors are driven by a gear train providing accurate synchronization or timing of the rotors. The rotors contra-rotate within the pump head carrying fluid through the pump, in the cavities formed between the dwell of the rotor and the interior of the rotor case. In hydraulic terms, the motion of the counter-rotating rotors creates a partial vacuum that allows atmospheric pressure or other external pressures to force fluid into the pump chamber. As the rotors rotate, an expanding cavity is formed and filled with fluid. As the rotors separate, each dwell forms a cavity. The meshing of the rotor causes a diminishing cavity with the fluid being displaced into the outlet port.

Principle of Operation
Piston pumps work by creating pressure by distributing energy into the pumped fluid. This action results in a pressurized fluid cylinder. Piston pumps are ideal when an application requires higher flow rates of fluid and low pressure, which can discharge fluid at a high rate with little effort.
