Liquid pump
A machine for the raising of liquids from a low to a high energy level for instance:
Back
- by the effect of a force on the pumping medium
- by transferring mechanical work to the pumping medium
- by impulse exchange
- by utilizing the energy of a moving column of liquid when suddenly arrested
- by making use of the viscosity of the pumped fluid
- by the action of a magnetic field on the medium to be pumped.
