Design Considerations for Reciprocating VS Centrifugal Pumps

Centrifugal Pump:

A centrifugal pump is a mechanical device that moves a fluid by transferring rotational energy from one or more driven rotors known as impellers. Fluid enters the quickly rotating impeller along its axis and is expended by centrifugal force along its circle via the vane tips.

Reciprocating Pump:

A reciprocating pump belongs to the positive-displacement pump family, which also includes the piston pump, plunger pump, and diaphragm pump. Reciprocating pumps can endure for decades if properly maintained. They can, however, succumb to wear and tear if not properly maintained.

In this pdf, we are discussing information among centrifugal and reciprocating pump

Key Points

Differences exist between centrifugal & reciprocating pumps, and their behavior while interacting with the piping system

Reciprocating pumps have many additional piping design considerations, not needed for centrifugal     

Pulsation must be considered in recip pump piping design

Mechanical piping supports must be considered

Small bore piping vibration must be considered in the design stage

Reciprocating pumps can work well, if they are designed well!
