Submersible pumps
|
Both shallow and deep wells,
repressurization from holding tanks
|
Advantages: quiet, efficient, capable of
pumping from great depths (1000+ feet), relatively easy to install, no
priming required,easier to service than other technologies
Disadvantages: represent slightly higher
level of initial investment, should not be used in swimming areas
|
Jet Pumps
|
Both shallow and deep wells (pumping depths
limited to approximately 100'), point wells repressurization from
holding tanks, pumping from open bodies of water
|
Advantages: Moderate cost savings, can work
on driven point wells, can be used in swimming areas (when properly
installed)
Disadvantages:require priming, less
efficient than submersibles, can be noisy, can be difficult to diagnose
system problems, deep well applications require 2 pipes in well and
remote jet assembly
|
Hand pumps
|
Pitcher pumps can raise water 20' with human
effort. Other hand pumps with submerged cylinders can pump water from
greater depths
|
Advantages: Pitcher pumps are inexpensive.
Can be operated without electricity.
Disadvantages: Need human power, seldom can
be configured to provide pressurized water.
