A Beginner’s Guide To All Things Pumps
If this is your first time purchasing a pump, you’ll likely need some assistance. So, we’ve developed a beginners guide to help get you started.
How pumps work
Creating somewhat of a vacuum, pumps use some type of impeller or rotor to push media. This media could be liquid or gas, however, all pumps work by producing areas of low pressure.
Basic pump parts
While there are different types of pumps, there are generally six main pump components. They are:

- NPSHa: Net positive suction head available to avoid cavitation.
- NPSHr: Net positive suction head required to avoid cavitation.
- Cavitation: The formation of small bubbles that burst. This can result in loss of capacity and pump damage.
- Density: The weight per unit volume of a material.
- Head: Pressure measured to determine the height a liquid will produce.
- Flooded suction: Suction fed by gravity. Common in centrifugal pumps.
- Pressure: The amount of force applied to the area.
- Prime: To fill the pump with fluid before operation.
- Strainer: A small metal mesh covering the inlet to prevent foreign objects from passing through.
- Dry running: Running the pump without any fluids present.
- Specific gravity: The ratio of a given volume’s weight to the volume of liquid to water.
- Viscosity: The density of a liquid affecting its ability to flow.
- Total head: The total sum of the head produced by the pump. Includes discharge head, friction loss, and suction lift.
Types of pumps
Pumps can be divided into two categories: Dynamic and Positive Displacement.
Those are then split further into four major pump types:
- Centrifugal. The most common type of pump, centrifugal pumps, use an impeller to speed up and transfer fluids. These pumps can be broken down into three sub-categories:
- Axial Flow — High flow, low pressure.
- Peripheral — Low flow, high pressure.
- Mixed Flow — Medium flow, medium pressure.
- Special Effect.
- Electromagnetic — Passes current through a right-angled magnetic field.
- Jet — Non-submersible, uses pressure to vacuum a constant stream of liquid.
- Reciprocating. These pumps alternate force and suction moving fluids in a linear motion. The main types of reciprocating pumps are:
- Piston, Plunger — Push media through a cylinder chamber.
- Diaphragm — Move liquids from one place to another using a diaphragm that motions back and forth.
- Rotary. Rotary pumps rotate in a mechanical motion, moving fluid through available spaces. The two main rotary pumps are:
- Single Rotor — Self-primed using flexing vanes to move media.
- Multiple Rotor — Self-primed with rotors timed separately.
