An accumulator is a container that is partially filled with liquid and partially filled with gas (usually air); its internal pressure is usually higher than atmospheric pressure. The accumulator sto…
Acid-resistant pumps are chemical pumps used for handling corrosive fluids, for example end sution chemical pump. End suction chemical pump is a kind of chemical pump which is suitable for chemical pl…
AC mains power is also called single-phase AC. In most European countries, the AC voltage is 230 V and the frequency is 50 Hz. However, parts of North America and Japan are different. They use 120 vol…
Actuator
The actuator is the control element used to intervene in the process. It converts the switching information provided by the control system into physical forces, and usually regulates mech…
Adjustable blade
If the blade can be permanently set to the desired position after being installed in the pump impeller, the blade is considered to be adjustable.…
Air lift pumps are used to lift liquids filled with solids. For this purpose, the gas is injected into the pipeline from below the liquid level by the compressor, and then vertically immersed in…
Analog interface
An analog interface is an electrical connection that forwards analog electrical signals to downstream electrical and electronic equipment or components for further processing. Sta…
Induction motor
Asynchronous motors have a passive rotor that is permanently short-circuited (squirrel-cage rotor) or temporarily short-circuited (see slip ring rotor). It can generate up to s…
Archimedes screw pump
The Archimedes screw pump is used to raise the fluid constant pressure to a given geodetic height by means of a rotating screw (a real screw). The screw works according to…
Axial thrust
The axial thrust is the resultant force of all the axial forces (F) acting on the pump rotor.
Axial thrust: the axial force in a single-stage centrifugal pump
The ax…
