It works in the slightest breeze, & has not given me a moment’s trouble. As you are aware, this mill is ‘working’ under extraordinary conditions. I mention that a recent cyclone took the roof off the stable adjoining the mill also the same iron off the roof of the kitchen & verandah, but did not have the slightest effect on the mill, which proves that the Comet Windmill is immune to cyclones and this certainly was ‘some’ cyclone. “...Outputs to 250,000 gallons daily...” On the Sesbania Trust Bore QLD a 35ft Comet Windmill gave an output of above 250,000 gallons daily under test by Government Engineers. “...Proven ability to pump distances...” On Bowen Downs Station in QLD a 27ft Comet Windmill with a 12inch pump has been supplying 12 miles (19.3km) of bore drain with up to 200,000 gallons daily for many years.

“The pumping capacities of Comet Mills, shown in the Table (below), are based on the number of pumping strokes (inches) in 7.7 m.p.h. (12.39 k.m.p.h) winds. Our Pumping Table is based on 10 hours of pumping over a 24 hour period allowing for slip/friction. Of course, if the wind blows for longer periods you will get more water.

Standard Range

Flush End Pumps (A)• Sizes: 1¾, 2 , 2¼, 2½, 3, 3¼, 3½, 4, 4½, 5, and 6 inches• Shallow pumping from bores and wells• Gun metal bronze construction• Leather or rubber buckets• 12” stroke• Larger sizes available on request

Syphon Pumps (B)• Sizes: 1¾, 2 , 2¼, 2½, 3, 3¼, 3½, 4, 4½, 5, and 6 inches• Surface water pumping from dams and rivers• Leather or rubber buckets• Vertical or side discharge (pictured)Vertical or side discharge (pictured)V• Heavy duty casting• 12” stroke• Larger sizes available on request

Stainless Steel Draw Plunger Pump (C)• Sizes: 1¾ , 2 , 2¼, 2½, 3, 3¼ and 4¼ inches• Deep bore pumping over 250ft depths• Ideal for hard or dirty water• Heavy duty pumps• Sleeve valve• 24” stroke

The tradition of high quality products flows through to the complete range of windmill pumps. Comet manufactures a standard range to suit any condition and can also supply custom made sizes for larger quantities of water.

“...Not affected by Cyclone...”Dear Sir, I have much pleasure in stating that the Comet Windmill erected at the Commercial hotel is indeed a beautiful piece of machinery. It works in the slightest breeze, & has not given me a moment’s trouble. As you are aware, this mill is ‘working’ under extraordinary conditions. I mention that a recent cyclone took the roof off the stable adjoining the mill also the same iron off the roof of the kitchen & verandah, but did not have the slightest effect on the mill, which proves that the Comet Windmill is immune to cyclones and this certainly was ‘some’ cyclone.

“...Outputs to 250,000 gallons daily...”On the Sesbania Trust Bore QLD a 35ft Comet Windmill gave an output of above 250,000 gallons daily under test by Government Engineers.

“...Proven ability to pump distances...” On Bowen Downs Station in QLD a 27ft Comet Windmill with a 12inch pump has been supplying 12 miles (19.3km) of bore drain with up to 200,000 gallons daily for many years.

All you need is a breeze....

Comet windmills are designed to operate in the lightest of winds, they are legendary for their sensitivity, simplicity and great strength.

They begin cost-effective operation in wind speeds as low as 4mph (6.5kph). Wind speeds of 4mph occur 95% of the time over the earth’s surface.

Comet Windmills are Direct Acting which means the Comet Windmill pumps more water at a lower cost, at any depth and in any wind speed.

With proven pumping ability and reliability for over 130 years, they are reliable and virtually maintenance free in harsh working conditions.

Simple DesignThere is no need for skilled technicians or tradesmen to erect, maintain or troubleshoot. Our experienced staff are only too happy to help. Comet does not endorse the use of non genuine parts as it causes more damage to your windmill over its life. Companies claiming to make parts

suitable for Comet Windmills and stating that these parts are stronger or better, have no grounds or proven experience to guarantee or make these claims. Genuine Comet parts have been made for over 130 years of unfailing quality from certified engineer drawings.

Accurate measuring is essential.Wind - Winds, especially the light breezes, must have free access to the mill from all directions. The bottom of the wheel must be at least 15ft (4.5metres) above all wind obstructions within 150yds (137 metres) of the mill.

Elevations - The mill should be loaded and balanced so that it will start pumping in light breezes. Its size depends upon the size of the pump and total elevation. The latter includes not only the vertical heights for suction and delivery elevations but also an allowance for probable water flow friction in the pipeline. The delivery pipe size should be at least half the pump diameter.

Suction - In a bore or well it is best to submerge the pump. For a creek or dam the pump should be placed close to the water and the suction elevation must not exceed 30ft (9m), or less if the suction pipeline is long.

InstructionsIt is very important that you provide accurate measurements so that the most efficient and economical pumping plant can be recommended to suit your requirements. First choose the diagram that is most similar to your proposed site. Answer the general data questions with accurate measurements and include pumping details.

General DataA. State the number of the diagram

which is similar to your proposed layout. If your layout is different, send a sketch showing the dimensions below and details of any pipelines.

B. Amount of water in gallons/litres required per day.

C. Height from ground level to top of tank or point of discharge.

D. Length of discharge pipe or delivery pipeline.

E. Capacity and type of storage tank.F. Distance and height of trees

and other wind obstructions within 150yds (137m) of mill site.

G. Are average wind conditions light, medium or good?

Comet Windmill selection guide....

Why choose a Comet Windmill?...Pollution FreeInstalling a Comet Windmill will reduce your carbon footprint. Windmills convert wind into mechanical energy with zero wind into mechanical energy with zero net CO2 emissions therefore lowering your impact on the environment. your impact on the environment.

Stability and SafetyAll Comet towers are designed with a high safety factor. The 4-post design and heavy steel construction provides greater stability to stand firm in strong winds. Four posts will always be stronger and safer than three. Available in 20ft to 60ft heights.

Long LifeThe Comet Windmill has been proven for over 130 years backing up claims of long life and sustainability. A maintained windmill can last many years with a little oil and checking bolts every six months to keep the windmill performing at its’ to keep the windmill performing at its’ best.

No Fuel or Power BillThis has to be the main draw card for the Comet Windmill. The initial outlay the Comet Windmill. The initial outlay for the windmill is quickly offset by the reduction in your fuel or power bill. All you need is a breeze, and the windmill will start pumping.

Low MaintenanceOur systems have been designed to be self sufficient requiring very little attention during the normal remote operation of a windmill. All steel work is hot dip galvanised, and the principal parts are cast from heavy duty materials giving longer life.

Ideal for Remote AreasThe Comet Windmill operates under all climatic extremes from snow fields and arid deserts, to tropical cyclones where they run without supervision for long periods of time.

Safety FeaturesUnlike other windmill designs Comet Windmills have a unique galvanised steel platform with antislip grate floor, perimeter toe plate and heavy duty support angles. The large area provides a safe environment to carry out maintenance.

How Far can the Water be Pumped?The powerful action of the Comet Windmill can push the water (depending on the size of the windmill head, and the pump diameter) up to 1,000ft. Apartfrom this, the distance is not much of an issue.
