Reciprocating pump

A reciprocating pump is a class of positive-displacement pumps which includes the piston pump, plunger pump and diaphragm pump. When well maintained, reciprocating pumps will last for years or even decades; however, left untouched, they can undergo rigorous wear and tear. It is often used where a relatively small quantity of liquid is to be handled and where delivery pressure is quite large. In reciprocating pumps, the chamber in which the liquid is trapped, is a stationary cylinder that contains the piston or plunger.

Types

By source of work
  • Simple hand-operated reciprocating pump. The simplest example is the bicycle pump, which is used ubiquitously to inflate bicycle tires and various types of sporting balls. The name "bicyle bump" is not really the most correct term because it generates more compression than volume displacement.
  • Power-operated deep well reciprocating pump
    • By mechanism
  • Single-acting reciprocating pump: Consists of a piston of which only one side engages the fluid being displaced. The simplest example would be a syringe.
  • Double-acting reciprocating pump: Both sides of the piston engages the fluid being displaced, with each stroke of the piston carries out both suction and expulsion at the same time. Thus it require two inflow pipes and two outflow pipes for double-acting pump.
  • Triple-acting reciprocating pump

    • Examples

    Some examples of reciprocating pumps include

  • Windmill water and oil pump
  • Hand pump
  • Axial piston pump
  • Radial piston pump
