The Very Versatile Submersible Video...
Is A One-of-a-Kind Video Training Tool
The Very Versatile Submersible Video is:
A video training tool aimed at informing the viewer of the many
advantages and multiple uses of submersible wastewater pumping equipment.
An eight-minute presentation that describes the "versatile submersible"
as..."A finely tuned machine designed to operate within the liquid being
pumped. It moves suspended solids as well as liquids. The submersible
takes little space...operates at a high hydraulic efficiency...and is
easily maintained and serviced."
Distributors, contractors, specifiers, users, wastewater facilities
manager, public officials, regulatory agencies, standards-setting
organizations, students at engineering schools, the general public
and others interested in learning more about submersible wastewater
pumps can use The Very Versatile Submersible Video to provide sound
background information or as a discussion starter.

The Very Versatile Submersible Video Script
Some man-made machines have a single purpose. The NASA space shuttle is an outstanding example. However complex its engineering and construction, it was designed to do one job -- take a crew and payload to space and back safely.
We would like to talk about a more down-to- earth machine -- one with hundreds of uses. It's the VERY VERSATILE SUBMERSIBLE pump. It does more jobs than most of us can imagine, and it does all of them extremely well.
Those who work with solids-handling pumps know how efficiently and effectively submersibles operate when installed in municipal lift stations.
We'd like to remind you of their hundreds of other applications throughout the world.
The VERSATILE SUBMERSIBLE is a finely tuned machine. It is designed to operate within the liquid being pumped. It moves suspended solids as well as liquid. The submersible takes little space... operates at a high hydraulic efficiency... and is easily maintained and serviced.
Let's discuss some of the ways this versatile machine serves pump specifiers and users throughout the world.
You may be planning an office building or a small plant. You'll probably need the VERSATILE SUBMERSIBLE during construction for dewatering.
Working with a coal mine or stone quarry? The submersible has many uses. Leachate removal. Dewatering. Moving runoff water to a holding basin or to a processing plant. And more.
Or perhaps there's a power generating plant on your drawing board. The submersible removes wastewater efficiently. Boiler blow-down and coal pile runoff are handled easily.
The VERSATILE SUBMERSIBLE finds many uses in industrial plants. Liquid handling and leakage collection pits in chemical plants. Carrying effluent in refineries. Handling sinter water and other grit in steel mills. Moving mineral-laden wash in synthetic fiber plants.
There are many applications for submersibles in the food processing industry. Processing foodstuffs, such as tomatoes for canning or freezing. Pumping gelatin or other process foods. Handling waste in a slaughter house. And more.
Whenever you want to move liquid which contains solids, the VERSATILE SUBMERSIBLE is your best choice.
That's true on water as well as on land. Submersible pumps dewater ships, barges and smaller boats. They pump bilge. Keep dry docks dry. And change water levels in locks, quickly and efficiently.
The VERSATILE SUBMERSIBLE helps people play and travel. You'll find them irrigating and dewatering golf courses. They remove water from airports, parking lots, and roadways. They're used in theme parks and stadiums. Submersibles frequently operate decorative fountains.
Submersibles help people live better. They protect water pumping stations from flooding. They dewater trailer parks. They move wastewater from homes, apartments and offices.
One fast-growing application is the low-pressure sewer system. Submersible grinder pumps are used to power small diameter pressurized sewers in areas where gravity piping is uneconomic or impractical. Grinder systems work especially well in hilly or rocky terrain. They sharply reduce construction and equipment costs.
In fact, submersible grinder pumps make it possible to serve many developments and communities in terrain where service was previously impractical.
The most common use of submersibles in municipal and other sewage systems is for lift stations. But there are many other municipal system applications -- including treatment plants, oxidations ditches, sewage lagoons, and storm water holding basins.
In municipal systems, submersibles are often preferred over traditional dry well/wet wells -- both for new and for retrofit installations.
Submersible installations take less space, since controls are above-grade and no second well is needed. There's less need for auxiliary equipment, such as forced ventilation, sump pumps and dehumidifiers. Submersibles mean a reliable, smaller, less expensive station.
Is it any wonder it's called the VERSATILE SUBMERSIBLE?
Millions of these reliable pumping systems are working today throughout the world. Submersibles were first applied in the 1950's. They now hold a significant share of the pump market in North America.
The VERSATILE, RELIABLE SUBMERSIBLE has many advantages for specifiers and users.
A primary advantage is the ability to operate under or within a liquid. Flooding problems are minimized to smaller areas. And since the pumps are cooled by the ambient environment which surrounds them, submersible motors have a long operating life.
Submersibles are engineered on a "rigid design" basis. This reduces stress on the shaft and bearings during start up and normal operation. They require minimal or no bearing lubrication.
Manufacturers offer a wide choice of non-clog impeller configurations to meet different hydraulic design conditions. There are open or enclosed designs. Additional choices include vortex, single vane or two,-vane types.
There are single and double seal designs. Both types have a seal-failure sensor to ensure reliable service. Double seals have a permanent oil reservoir between the seals.
Submersible pumps use proven, field-serviceable motors. They are available in single or three-phase models with thermal protection built in. Some are oil and some are air-filled, and they range in size to more than 500 horsepower. Explosion-proof designs are available when needed.
There's a variety of accessory and control equipment, to ensure proper operation under nearly any condition. In lift station applications, for example, there are prefabricated stations, choice of access covers, and handy guide rail systems -- all assuring easy maintenance.
There are a variety of controls, for both lift stations and other applications. Control choices include starters, ground fault interrupters, level controls, and visual, audio and telemetry warning systems.
There are control enclosures for any specific condition. Variable frequency drives and multi-speed motors are readily available.
That's the VERY VERSATILE SUBMERSIBLE wastewater pumping system. it's reliable, compact and safe. It works effectively and efficiently. Importantly, the installed cost of a new or retrofitted submersible is usually less than that of traditional systems.
Whether yours is a sewage or an industrial solids-handling application, you can rely on the VERSATILE SUBMERSIBLE.
