In-Depth Information
In case of force mode pump, the pump is installed below the water level and the
lifting capacity is not limited by atmospheric pressure, rather on the force of the
pump (or prime mover). Turbine pumps and other submersible pumps fall into this
category.
12.2.4.2 Classification Based on the Position of Prime Mover
Based on the position of motor (power), the pumps can be grouped into
Surface mounted
Submersible pump
Surface-mounted pumps have motors which are above ground - although deep well
types may have pump parts hundreds of feet below the surface. Submersible pumps
are designed to spend most of there life underwater, only being pulled out every
several years for routine maintenance.
12.2.4.3 Classification Based on the Type of Water Use (or Field of Use)
Based on the type of water use, the pumps may be categorized into
Water pumps
Wastewater pumps
Well pumps
Sump pumps
Sampling pumps
Drum pumps
Water pumps are designed to move water that does not contain suspended solids
or particulates. Applications include water supply, irrigation, land and mine
drainage, sea water desalination.
Wastewater pumps are used in the collection of sewage, effluent, drainage, and
seepage water.
Well pumps are most commonly used to bring water from wells and springs to
the surface.
Sump pumps are used in applications where excess water must be pumped away
from a particular area. Sump pumps generally sit in a basin or sump that
collects this excess water.
Sampling pumps are used to monitor liquids, air, and gases. They are usually
portable and developed for specific tasks.
Drum pumps are used to transfer materials from a container into a process or
other container. They may be electrically, hydraulically, or pneumatically
powered depending on the working environment or application.
