Motor converts the electricity to mechanical work.
Pump is a device to force a gas or liquid to move in a
particular direction

Answer / alianwar

MOTOR : An electric motor uses electrical energy to produce
mechanical energy, usually through the interaction of
magnetic fields and current-carrying conductors. The
reverse process, producing electrical energy from
mechanical energy.
PUMP : A pump is a device used to move fluids, such as
gases, liquids or slurries. A pump displaces a volume by
physical or mechanical action. One common misconception
about pumps is the thought that they create pressure. Pumps
alone do not create pressure; they only displace fluid,
causing a flow. Adding resistance to flow causes pressure.
Pumps fall into five major groups: direct lift,
displacement, velocity, buoyancy and gravity pumps

Answer / ln sahu db power

motor is a electrical device which convert electrical power
into mechanical power. it is named according to their
application .if it is used for transfer of liquid then it is
called pump and for air then it is called blower etc.
