Flood
control systems need pumps capable of transferring huge quantities of water
quickly in times of severe rain, stormwater accumulation and drainage problems.
Propeller
pumps are used where strong flow but relatively low head is required.
This makes them appropriate for pumping huge volumes of water. Flowmore’s
propeller pumps can provide flow rates of up to 60,000 m³/hour and heads of up
to 30 meters. They are listed for flood control, dock drainage, dewatering,
river water, raw water and water supply applications.
Why
are propeller pumps good for flood control?
Propeller
pumps are good for pumping large amounts of water with axial-flow impellers.
They are therefore beneficial where a high discharge capacity is of more
importance than a high pressure. Flowmore supply vertical single or multistage
propeller pumps for wet and dry pit applications. Depending on project needs,
pumps can be fitted with open or semi-open impellers, various lubrication systems,
and vertical solid- or hollow-shaft motor designs.
Flood-control
systems typically need to evacuate enormous amounts of collected water in a
short period of time. A propeller pump may be appropriate if the application
requires high flow at relatively low head. Flowmore particularly specifies
flood control, dock drainage and dewatering as applications for its propeller
pump line, therefore the technology is useful for varied large-volume
water-handling requirements.
Choosing
a Pump for Various Applications
The
selection of a flood-control pump depends on various parameters including
needed flow rate, head, installation layout and operating conditions. Flowmore
has a range of building materials such as cast iron, cast steel, stainless
steel and duplex stainless steel depending on the component and application.
Mechanical seals or packing glands are also supplied on a project basis.
Conditions
of installation are also crucial. Flowmore propeller pumps are available with
wet or dry pit arrangements, with different driving and lubrication
arrangements providing flexibility during system planning. For detailed
selection the business suggests to use the individual pump family curves. This
guarantees the selected pump will satisfy the hydraulic needs of the particular
project.
Flood-control
infrastructure includes drainage canals, pumping stations, docks, rivers and
dewatering facilities. Flowmore describes its propeller pumps for flood
control, dock drainage, dewatering, river water and raw water applications. The
series includes pump sizes from 200 to 1800 mm to suit a variety of water
handling requirements.
Conclusion
When
you need to transfer large volumes of water at a relatively low head, propeller
pumps are a good choice for flood control systems. However, the pump should
always be selected according to the actual hydraulic and installation
requirements. Flowmore provides propeller
pump systems for flood control, drainage and dewatering applications.
