Spitfire Radial Arm Jet Mixer
The Spitfire Revolution System eliminates those awful irrigation tasks in the wet and cold of winter and shifts effluent irrigation into the warm and dry early summer days. Grass growth is improved when effluent is irrigated later in spring when grass needs dilute water and nutrient. This system is a grass production tool.
The pond provides a cushion period for wet spells (when you shouldn't irrigate) or when you are too busy or short staffed. The ponds are all circular so that stirring takes place in every "corner".
Effluent storage capacity is the essential component in the process called 'Deferred Irrigation'. It is the vital missing ingredient from most of our dairy farms. It let's you irrigate when the plants want to be irrigated so as to grow.

Why use a Spitfire Radial Arm Jet Mixer?
Spitfire Radial Arm Mixer (RAM) with large pressure jets was designed so dairy farmers could hold all effluent in one pond and then irrigate the solids and the liquids all together without introducing other tasks.
- The entire pond is well-mixed unlike ponds with floating mixers. No solids islands or corners with build-ups of solids
- Unlike a separator system, there is only the irrigating task, and no other solids spreading or storage chores.
- No digging out solids and ruining a liner.
- Creates a dilute, uniform mixture that can be passed through an 10mm + nozzle.
- Clean, tidy and contained.
2014 Radial Arm Jet Mixer
Rectangular ponds with localised mixers have dead zones where solids accumulate so that you have to clean them out later with a digger, risking liner damage and subsequent leaking.
Our Spitfire philosophy is to stir the pond so thoroughly that when you irrigate from it, all the solids and the liquids get out onto the pasture at the same time.
- Solids spreading leaves a heavily applied, concentrated and unknown amount of manure all over the pasture, which might be a hazard to the environment and tough on the pasture.
Spitfire Radial Arm Jet Mixers (RAM) span the pond from the centre to the outer embankment. This year (2014) we have moved to a "no moving parts over the liner" philosophy and have installed the first "Jet-Mixer" at Galatea. A large pipe is suspended from the radial arm just above the bottom of the pond. Attached to this are 10 - 12 jets about 28 mm diameter. The large pipe is pressurised by a 150 mm suction submersible pump so the jets scour the entire pond base and aerate at the same time. They are always the same distance from the bottom of the pond, irrespective of the pond water level.
Fixed location floating mixers strike the bottom at "low tide" and fail to stir the bottom at "high tide".
The RAM mixer arm rotates around the pond (see video, above) ensuring that the jets get to stir up the entire pond volume leaving no dead, unmixed zones or surface crust. A cutter screen at the central drain point chops oversize particles and screens out the objects that block pumps and irrigator nozzles.
The ponds are sized to collect all yard and pond-area rainfall.
Ponds are constructed in modular sizes of 1500 to 20 000 cubic metres - Plenty of holding capacity for large or small herds. They have a concrete track to eliminate carriage wheel ruts.
The circular pond is very easy to construct and we arrange for full geotechnical engineering advice on the construction.
RAM jet mixers will shortly be available for tanks (August 2014)
Both the mixer and outer wheel drive use less power than most floating mixers. Only 11.0 kW is needed for the thorough mixing of the largest pond of 90 metres diameter.

The Spitfire Radial Arm Mixer sweeps and blends the liquid to a consistent mix and allows the pond to clean itself year after year. There are no islands of sludge to be removed later with possible damage to liners.
