Plunger pump

[1][2] The invention of the plunger pump is attributed to Samuel Morland based on a patent of 1675.

The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive.

The volume of the fluid discharged is equal to the area of the plunger or piston, multiplied by its stroke length.

A stuffing box or packing is used to seal the joint between the vessel where the medium is transferred and the plunger or piston.

Plunger pumps' component materials are chosen for wear and contact with the type of medium.
