Centrifugal pump Wikipedia

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller

Sand Filter an overview ScienceDirect Topics

Continuous sand filters (see Fig. 26.6) are gravity-driven depth filters with countercurrent flows of filter sand and dirty fluid. Dirty fluid is introduced into the bottom of the structure, and clean fluid is collected at the top. An airlift pump carries dirty sand from the bottom of the structure to a pneumatic sand washer at the top.
