Hello everybody
Can you help I need to chose between an alltec advantage and a high spec ninja. Hopefully in time for carpex.
After disscussions yesterday with Steve Saunders at alltec, who was very helpfull, it seems that they are not happy about supplying their machine with a pump that has a higher psi/flow rate than their standard offering The reason being that they are not happy with the quality of the pumps avalible. Fair enough, that leaves the advantage with135psi and 3.7 liters per min flow rate
The ninja comes with a 400psi Induction pump motor option which martin at ashbys said had a 1.5 gallon per min flow rate(not sure if us or imperial)
I hear mixed reviews about these pumps and would like to get to the bottom of it before making an expensive mistake.
So if any users or anybody else with any reports good or bad could please spare 5 mins sometime to give me a ring, no rush I would be very gratefull.
Thanks in advance Michel

I think its more to do with the available space inside the alltec machine than anything else. A 400 psi pump is a lot bigger than a 135psi. A lot of machines use 350psi or 400psi pumps that are very reliable- recoil 3 - cfr 400. The reason that ashbys like the ninja so much is because its got tons of space inside to fit all manner of goodies :D

Thanks for that Chris
Does anybody out there know of a pump with better pressure and flow rate than alltecs standard offering that would fit and could be made to work in the advantage

Michael,
I can only comment on the Ninja as I purchased one last year and I'm over the moon with the results and the machine. I find going upstairs a nightmare for office cleaning, however, I now have the Texatherm system.
What's the spec your looking at on the Ashby's?

Michael, if you are thinking about a high powered portable you should check out Extracta and Cross-American too.

when it comes to changing your pump and you want a pump the runs forever at upto 800psi fit one of these

with this motor
(http://img68.exs.cx/img68/3220/elec_motors.gif)
total cost about £600 but is worth it (the cost is why I think manufactuers don't use it)

Will they fit in a Ninja?

Who sells them, Mike.

Len the pump head is the size of a bag of sugar, the motor is 1hp so is the same size as used with any pump over 300psi.
Finton the pump isa Hypro from www.dualpump.co.uk the motor is from any supplier
I've used this pump for 8 months and with 2 x 3 stage it still uses 1 power cord.

Just a thought chaps, would a pump and motor from a pressure washer be worth a try?

I've just checked my invoice, i got the price wrong. its about £400 :)
if you used a pressure washer pump you'd have to have a bypass valve, its a bit overkill for carpet cleaning.
Mike

Mike, Would you think a pressure washer pump if driven at a slower speed could be made to produce usable PSI for carpet cleaning? I imagine running a pump well below its max capability will improve its life span too.
Paul
-
to be truthful i don't know, but how will you get the pump to run at a lower RPM? You'd have to use a pulley system which totally alters the make up of the machine.
some truckmount use high PSI pressure washer pumps and they divert the extra pressure with a bypass uploader valve you could use the same system for a portable.
but most portables don't have the internal space to fit the bigger pump & motor

Mike, Using a speed controller to limit the voltage to the motor would take up very little space and give control over speed therefore PSI. Being a design engineer (well i was for ten years)I have a few contacts in electrical engineering who would be able to say if this is a viable idea ??? I'll give them a call.
If it is it may be a cheap way of getting decent PSI in my commanche which has plenty of space.

Paul,
The reasons that pump output is normally controlled by an adjustable bypass valve are cost, reliability and adjustable range.
Electronic speed controllers are expensive and when they reduce speed beyond a certain point there can be a sudden reduction curve when associated with pressure pumps. They also tend to fail completely without warning, whereas a mechanical valve may become inefficient but remain usable for an extended period.
-
Thanks John, So would running a pump and motor intended for a commercial pressure washer along with an adjustable bypass be viable???
Paul

Paul,
It is auseable option but as Mike has sugested, it is an overkill.
In all probability a high performance pressure washer pump would require an additional lead to your Comanchee because of its' current draw.
The pump Mike recommended would supply more pressure than you would find useable for carpet cleaning anyway, and do so at reasonable cost.
Before actually buying one I would sugest that you check the hieght on the motor (on its rubber mounts) and make a cardboard dummy .25" oversize to check that you have sufficient clearance of the lower vac unit.
If you do not use the attache heat exchanger, the metal plate at the rear of the machine would be a good mounting point for the flow valve.
-
Thanks John, I was just lookin for a cheap way of getting higher PSI, with pressure washers available so cheap these days thought i may be a good idea.
I plan to get a new machine early next year, hopefully a recoil 3 so not worth spending too much on the commanche.

Anyone know of a supplier for pumptech pumps in the UK?
thanks
