Sump pumps are used to pump water out of basements. There are two main types - submersible pumps, which are fully immersed in water, and surface pumps, which are not immersed. Submersible pumps have advantages like lack of friction and cooling of the engine. Surface pumps can pump from any depth but are harder to maintain. Key manufacturers of sump pumps include Zoeller and Little Giant, which produce reliable pumps using their own components. Sump pumps are used to drain basements, wells, trenches and more, and come in models suited to different applications and water conditions.

1. What is a sump pump for basement?
Figure Types of pumps for waste water
A detailed discussion of what constitutes a
basement pump. These devices are also
known which - sump pumps are centrifugal
type. They can be divided into surface and
submersible.
The peculiarity of submersible pumps is that
they are fully immersed in the pumped liquid.
On this basis, their engine waterproofing that
water does not leak into the electrical part of
the pump. The main advantage of a
submersible pump for dirty water - is the lack
of friction of the machine. Also, the good
points are the low noise, easy to install, long
battery life. Pumped water submersible
pump at the same time is also a cooler
engine, which is very important after
prolonged use.
Another type of pump for dirty water -
surface. Their very name already suggests
that this type of pump is not immersed in the
pumped liquid. Used for water intake hose.
The advantage of this type is that they can
pump water from any depth. They are easy
to disassemble and maintain.
Basement pump installed near the drainage
or sewage pits, from which it pumps water.
When the device is always connected status,
and as soon as the water exceeds a
predetermined parameter, triggered a
mechanical float and the pump begins to
pump fluid. Level drops and the pump stops
running. In submersible pump have its
drawbacks. Chief among them - the
complexity of maintenance.
Choosing a surface pump, you should consider its performance, depth and height of lifting the
water. To compensate for the loss of power surface pumps complement ejectors that promote
water circulation.

2. Sump Pump manufacturers
Pump is a device designed for pumping fluid under pressure, is used in municipal,
agricultural, industrial and many other industries. However, this is quite a broad term. All
pumps are divided into groups and sub-groups, one of which are pumps for dirty water. Of
what they are, where applicable, as well as on the manufacturers who produce them, we can
learn from the article.
Little Giant, Zoeller, Wayne, Goulds, Flotec, Liberty Pumps, Dayton, Ridgid
Manufacturers of sump pumps for basement

3. Sump pumps specification
The need to drain excess water from flooded basements, drainage wells, construction of
trenches, flooded during high water or heavy rainfall, there often enough. For wastewater
from various tanks used special drainage pumps which provide efficient pumping polluted
liquids with a small amount of solids. The most common pump for pumping water is used:
 Public utilities
 Construction
 Industrial
 Agricultural sector
 Residential Houses
 Pools
The drain pump can be used as an element of the fluid flow of exhaust filter or as a stand-
alone installation to perform a stand-alone task: cleaning the pool, draining of flooded cellars,
as well as for irrigation or watering the garden.
Features of sump pumps for pumping water
Unlike other types of hydraulic equipment, pumps for pumping water can handle liquids
containing solids and fibrous. Pumped water pump enough so rarely perfectly clean, so pump
design provides high reliability and durability of the installation, which is easy to cope with
particles of diameter 3-12 mm. Drainage pumps are often combined into one group with fecal
pumps, which are used for sewage systems and can easily cope with the waste water
containing solid particles are large enough or long, thanks to a special cutter.
The task of the pump for pumping water is the water rise to a very great height, as do pumps
for water systems. Therefore, the main requirements for drainage pumps - reliability and high
performance. The work of drainage pumps provides electric motors. The plants are from
single-phase and three-phase networks. However, for use in cases remote from power lines,
and there are places pumps internal combustion engine.
Types of sump pumps
By mounting the pump for pumping water can be:
 Surface
 Immersion.
Surface pumps are mounted on a special platform directly above the water reservoir. The
pump connected to a flexible inlet pipe, which is lowered into the water. Thus, water is taken
without contact of the fluid pump housing. These operating conditions can simplify the design
of the pump for pumping water and not to impose strict requirements for waterproofing the
motor. Surface pumps can be stationary and portable and are used almost everywhere,
where pumping water in any amount.
Submersible pump for pumping water completely or partially immersed in water. The liquid is

4. sucked directly into the bottom of the installation, which is protected against ingress of solid
particles a special filter. The motor is securely isolated from contact with the water. All welted
parts are made of durable anti-corrosive materials (stainless steel, cast iron, aluminum,
plastic).
Feature of the submersible pump models for pumping water is the presence of the float
switch. This design element is strictly monitors the protection of the installation of "dry run", as
soon as the water level drops to the critical value, the pump turns off immediately. The same
float switch can have a surface pump for pumping water: it acts as a switch on the pump
when the water level rises to the set level, which requires pumping liquids and off after
lowering the water level to a safe figure.
Type of Applications
The main purpose of sump pumps for Little Giant is sanitation. Most often they are used for
the following tasks:
 Sump of flooded areas
 Struggle with the wet soil
 Pumping water from pits, trenches
 Emptying the various reservoirs.
Such equipment can be found in construction, municipal farms, rescue units on farms.
Features
Any Little Giant sump pump is designed for pumping
water of varying degrees of contamination with possible
inclusions of solid particles of sand, silt. The main
distinguishing feature of the sump pumps is the high
reliability and performance.
The design consists of a pump motor and pump unit with
one or more impellers. Movement of fluid is provided by
the rotation of the impeller, which are equipped with
special blades to create a centrifugal force, which
causes fluid to move.
The main part is a submersible sump pumps. For normal
operation, they must be immersed in the liquid to be
pumped in whole or in part. Many models are equipped
with a float switch, which manages the pump: it turns on
and off depending on the water level changes.
In view of the special conditions of use of a Little Giant sump pump has the following common
features:

5.  High strength
 Full waterproofing engine
 Working with liquid temperature above 40 degrees
 Lightweight
 Low noise.
