Pursuit Dynamics plc is a UK based research and development company, which was founded in 2000 to develop and commercialise a revolutionary pumping and propulsion technology. Pursuit Dynamics (symbol: PDX) was listed on the Alternative Investment Market of the London Stock Exchange in May 2001.



PDX 25 Sonic.

The PDX Technology is a steam-based system that has applications in both pumping and marine propulsion. It is cheap to manufacture, extremely robust, contains no moving parts and is virtually impossible to block. Pursuit Dynamics owns 100% of the Intellectual Property Rights that surround the PDX Technology.



Pursuit Dynamics is now working towards the commercialisation of the technology it has developed.

Pursuit are rumoured to be close to closing their first deals, which may be in the food processing industry.

fujisnapper,

Many thanks for taking the trouble to post that, and I agree it is positive, and I remain a holder, am considering adding a few more, and regretting not taking a few in the dip now.

Andy.

Hi guys, this one seems to be well followed on here but I have just lifted this post from The Motley Fool site re - to the pump. Could this be one of the reasons for recent weakness?................

As chatting about engineering is more interesting than wondering why my shares are down today I thought I'd add to the propellor debate by sticking an oar into the Pursuit Dynamics steam powered pump. Originally this device was intended to replace propellors but is now being promoted for many uses.

Although I've read quite a bit about it here and in other places (PDX website and a site referenced on the PDX board) nobody ever seems to talk about the problems with the device so I thought that I would.

As I see there are many problems with the PDX pump -

1. It's appallingly inefficient. To make steam really effective you have to expand it from a very high pressure to a very low one extracting all of the energy on the way. In this device the pressure is converted into an impulse jet which, as nero discovered, isn't an efficient engine. The steam then condenses which helps the flow by creating a vacuum. I think PDX claim 10% with water up to 20% with gravel. The higher efficiency with gravel is logical as it doesn't condense the steam as quickly as water. However these seem to be strangely round figures to me and probably ignore the boiler efficiency. Somebody who tried to work it out reckoned it would be more like 3%. Either way with traditional pumps in the 90%+ region it's going to be a lot more expensive to run.

2. It uses steam. Steam comes from boilers and boilers can be dangerous. They have to be regularly checked and certificated which is inconvenient and costly.

3. The pump exhibits no control over the flow. This I'd rate as half a problem as some other successful pump designs don't either. However in a great many industrial processes, including food production, where ingredients are mixed the pumps not only pump they also meter the flow to get the correct mix. So PDX ruled out for these applications.

4. It injects water into whatever is being pumped. This rules out most chemical applications. Even in situations where it can be tolerated, i.e. food, this means that the source of the water, the boiler, will have to be hygenically cleaned at regular intervals. Consequently general purpose boilers couldn't be used as the supply of steam.

5. It can raise the temperature of the pumped medium above boiling point. The local effect of the impact of the steam will be to heat some parts to high temperatures which of course will 'cook' them. A drawback in the food industry unless you want it to happen.

6. It macerates (mixes/chops up) the pumped medium. May be advantageous but not always.


The most likely field for success is where the efficiency is not an issue because it's desired to heat the medium anyway, where maceration is desirable, where the addition of water is tolerable, where steam is used anyway and control of the flow is unimportant. All of this points to the food industry but not so much as a pump but as a combined macerator/cooker/pump with the accent on the first two as the ingredients will have to pumped by metering pumps anyway. However this is a much smaller field than people think and there simply isn't big business in it.

I think the PDX pump may find a niche in the market but no more than that.

Tawny


cheers GF.

These points have been more than covered in the last yr,i'm not prepared to go into details now, but the facts are this product works look at the welcome example production and time saving figures bettered by 90%,these are mindblowing figures that are not being ignored by many industries all the questions above have been answered in there entirety in the last year if u look you will find them on various websites thats old news,Deals are whats concerning the company now and the reason were all here,this share price will look absurdly cheap come the end of the yr anyone who took the opportunity to top up on recent weakness made a very shrewd move,paper and dairy look favourites to be the next deals announced as it seem the company are now in mature disscussions as ever dyor !!!!

Goldfinger,

This post isn't even a good attempt at a deramp IMHO!

Point 2 is frankly laughable.

point 3 is completely incorrect IMHO.

point 4 correct, but I believe PDX are testing other chemicals instead of water now too!

Point 5 I have held a solution in a thin glass jar, just mixed by the pump, and it certainly wasn't boiling|!

Point 6 lol!, really getting desperate now!


Interesting that the knocker refers to "the pump" whereas PDX and indusrty recognise it as a processing unit!

Maybe an indication of just how far out of touch he is with the capabilities of the PDX? I suggest he visit www.pursuitdynamics.com, and read up for himself!

Goldfinger,

I see that same post has been spread over many bulletin boards today, with references to it being slipped into threads!

Someone seems anxious to deramp it IMHO!

Hi gf (Ollie). Regarding the "Tawny Owl" material on the Fool, a chap called Le Petit Fou and I tried to answer it, but on Paulypilot's Pub, here's the thread

http://boards.fool.co.uk/Message.asp?mid=8530355&sort=whole#8531197

...not with any great wisdom maybe (I am Patohat)

"Tawny Owl" reminded me of some twerpy deramping stuff on ADVFN... but I am gonna stay out of these personal things, it does no good. PS you did right to exit TMG, wish I had been as fast on my feet! Best wishes Pat

Hi andy, if you check that post out on that site it as 24 recommendations and as there are only about 50 active posters on that site at the best of times( ie, half of the board) as a new buyer of the stock early last week you can see why I was concerned.

I do not know one jot about engineering but have read many an article on the pump usually excelent pieces although Evil Knievil in his last web cast indicated it was now either make or break time for the product and yes he is long very long on the stock.

I thought that you were of the kind that liked to hear both sides to the argument ie, the bull and bear case, and felt these concerns were well worth flagging up.

cheers GF.

Goldfinger,

Yes I do like to hear both sides, providing it's genuine and objective, but this stuff has all been done before, several times in fact, by various posters such as Ashley James on the ADVFN bb.

They'll be posting about "problems" with the patents next!

That's already been done a couple of times too BTW!

I too know little about engineering, although my father was a pump and compressor design engineer all his working life, and he has looked over the PDX spec, and was quite impressed.

With regard to the PDX, I agree with EK, it really is make or break in the next few months. It is a high risk, high potential reward stock, and I have a line in the sand, should it be needed, which hopefully it won't.

My personal view on the news that PDX have not signed a deal with "the confectioner" is one of disappointment. I never saw the logic in trying to negotiate an "exclusive" deal, and I think that trying to do this is holding the potential larger deals back.

I also believe the Welcome Foods deal was done and announced to support the price, as well as proving the technology works. The performnce of the PDX utilised by Welcome is nothing short of superb, according to their announcement, so this reassures me somewhat that it can do what they say it can.

I hope this presents me as holding a balanced view of PDX, but the deramps have been done before, and I'm not impressed by the multiple logon brigade.

Thanks for that reassurance andy, I will let you know what Evil as to say this coming wednesday.

cheers GF.

GF,

Appreciated.

GF,

Have you any update from EK please?

Nice to see a healthy bounce today after the last couple of day's mauling, and I'm hoping PDX can now establish a base above 130p.

Suggestions over at ADVFN of rumours re possible deals, but they are ONLY rumous, and nothing has been posted to substantiate them, or otherwise.

Andy.

Buyers pumped up the Volume at PURSUIT DYNAMICS, sending shares of the steam propulsion specialist 8p higher at 138p.
They heard whispers that it will confound the pessimists and roll out a couple of 'interesting' deals before the end of the month. A dairy products company and a Leading confectionery group is believed to be on the verge of signing up to use Pursuit's pump technology.
Called PDX, it can pump, mix, soften and heat materials using supersonic shockwave. Welcome Foods Ingredients became a customer this year after a pilot study showed PDX had cut manufacturing times by upto 95% and cleaningf times by upto 80%.
Chief executive John Heathcote is apparantly sitting on sizable contracts - one with a leading paper manufacturer - which will see the light of day shortly.
After the recent shenanigans in the groups sahre price, shareholders should begin to feel a lot happier.
The London Stock Exchange was called this month to probe a 13pc fall in the price ahead of the company's revelation that after eight months of negotiations it had failed to reach an agreement with a soft drink and confectionery manufacturer over the use of its technology. The LSE went away happy

Andy,
More than rumours - in PDX's 30 April RNS, the very last sentence states that the Company is in "mature discussions" with leading companies in the dairy and paper industries. That's presumably code for nearly at the stage of contract signing.

beaufort1,

Yes I agree, but "nearly" is not signed!

I hold, and am hopeful that deals will be forthcoming, but I realise that until such time, nothing should be taken for granted, and the fat lady cannot be heard, YET!

Not trying to sound pessimistic, merely cautious.

PDX have released results today, pretty much in line with expectations, and cash in hand is strong, but no deals were announced. There has been an early fall, which seems to have been used by some to top up, as the price is (hopefully) rebounding now.

I'm not sure what people expected today, but results are simply just that, results. I didn't expect any earth moving deal to be announced, so why people that were happy to hold yesterday would be selling today in a mystery.

I have to admit to hoping the small delay was down to PDX trying to conclude a deal to coincide with these results, but it was only a small hope, and certainly not any expectation.

A bear raid was expected, who knows if anyone was waiting for it?

I am still very much with you Andy (although I admit to considering the release of some before I was properly awake at 8.03am!!).

Am holding too, the technology is there just a matter of waiting for contracts to be announced, happy to be holding in this company long term. : - ) Good luck to all holders.

Oakapples142,

Yes it was a bit scary earlier, and particularly after BPRG and TDM have suffered precipitous falls so recently!

I have become a little used to the market's knee jerk reactions, but it's always worrying until the price turns.

What PDX needs to do now, IMHO, is turn one of their current prospects into a signed deal, and as soon as possible too. Maybe they need to focus on the most likely one to sign, rather than the one that may generate most revenue? Without losing focus on other deals of course!

The technology seems to have so much potential, I can only see success long term here.

Oakapples142 / Adieh,

Well the price is now 119.5p MID (118 - 121).

Hoping the recovery continues, the fall this morning was well overdone IMHO, results were as expected.

Andy / Adieh

In my Investment club two of our members are engineers and both agree this innovative system is a winner.
The company wouldn`t hold back good news a little to affect a price drop (called sweethearting") would they ?!!!!. Of course not that would not be playing cricket!!
