Different Types of Pumps:
|
|
|
|
|
|
Submersible pumps work in the water source
|
|
|
|
|
Easy to use automatic pumps.

When a sump pump isn't an option to drain flat surfaces
|
|
|
|
|
When the water being pumped isn't clean.

Submersible Pumps
|
|
|
|
Few items provide as quick a return on investment and as long a work life as
submersible pumps. These pumps have the advantage of being able to work in the
water source being pumped. As a result the submersible is not subject to the suction lift
limitations of other pumps. No suction hose is required helping to save money and time
while eliminating a potential source of problems. The pump is only limited by the
discharge head it is capable of producing.

|
|
|
Centrifugal Pumps
|
|
|
|
 |
|
|
|
|
Centrifugal force is defined as the
action that causes something, in this
case water, to move away from its
center of rotation. All centrifugal pumps
use an impeller and volute from the
heart of a pump and help determine its
flow, pressure and solid handling
capability.
|
|
|
|
|
|
|
Another key component of the pump is its mechanical seal. This spring-loaded component consists
of two faces, one stationary and another rotating, and is located on the engine (or motor) shaft
between the impeller and rear casing (see above). It is designed to prevent water from seeping into
and damaging the engine (or motor). Pumps designed for work in harsh environments will require a
seal that is more abrasion resistant.
|
|
|
|
Diaphragm Pumps
|
|
|
|
 |
|
 |
|
|
|
Diaphragm Pumps: Use a positive displacement rather than centrifugal force to
move water through the casing. This means that the pump will deliver a specific
amount of flow per stroke, revolution or cycle. Diaphragm pumps can be used with
muddy water, up to 30% solids by weight.
