Pumps

The document discusses different types of pumps including reciprocating pumps like piston pumps which use reciprocating motion and positive displacement to transfer liquids or gases. Rotary pumps also use positive displacement with each revolution to maintain a constant capacity. Centrifugal pumps use one or more impellers and centrifugal force to throw fluids out along a circle through the impeller tips. Turbine pumps resemble turbines and are often used for high head, low flow applications like well water. Jet pumps use the kinetic energy of a driving medium like steam or water to draw in other fluids and release them under pressure. Submersible pumps are used to pump water from underground wells or reservoirs. Sump pumps remove water from basement pits or sumps to the outside

Pumps

- A pump is a mechanical device that propels liquids or occasionally slurries. It typically converts
electrical energy into hydraulic energy. Depending on how they move the fluid, pumps can be divided
into three main categories: direct lift, displacement, and gravity pumps.

Reciprocating pump
- A type of positive-displacement pumps known as reciprocating pumps comprises the piston pump,
plunger pump, and diaphragm pump. Reciprocating pumps can last for many years if properly
maintained. However, if neglected, they are susceptible to deterioration.

Piston Pump
- A form of positive displacement pump called a piston pump has a high-pressure seal that
reciprocates along with the piston. Piston pumps can be used to compress gases or transfer
liquids. They can function in a variety of pressures. It is possible to operate at high pressure
without negatively affecting flow rate.

Rotary pump
- Positive displacement pumps, such as
rotary pumps, move a fixed volume of fluid with each revolution. These self-priming pumps give close to
constant capacity regardless of pressure.

Centrifugal pump
- Using one or more driven rotors, known as impellers, a centrifugal pump transfers rotational energy
from one or more mechanical components to move a fluid. Centrifugal force causes fluid to be thrown
out of the quickly revolving impeller along its circle through the vane tips.

Turbine pump
- A type of centrifugal pump known as a turbine pump moves liquids using impellers that resemble
turbines and have teeth that are aligned radially. In installations that call for high head, low flow, and
compact construction, turbine pumps are frequently used. Water is frequently removed from an
underground well or reservoir using a vertical turbine pump.
Jet/Ejector pump
- Vacuum pumps known as "water ejectors" are powered by high pressure steam or water (or a
comparable media). They draw in gases, vapors, or other liquids using the kinetic energy of the driving
medium and then release the resulting mixture under pressure.

Submersible pump
- Vacuum pumps known as "water ejectors" are powered by high pressure steam or water (or a
comparable media). They draw in gases, vapors, or other liquids using the kinetic energy of the driving
medium and then release the resulting mixture under pressure.

Sump pump
- The equipment that pumps water from your basement to the
outside of your house is called a sump pump. A sump is a pit that
was naturally formed, typically in the form of a hole dug beneath
the surface of your basement floor. The sump pump is kept in this
basin-shaped pit.
