I agree . its about the end user recieving the correct advice.
of course better quality stators make all the difference. (someone has to make the best, Pft are the biggest rotor stator supplier in the world) They only recently purchased KTO and never previously made them themselves KTR, Kachele and many other manufacturers are also market leaders in the production of R/S
softer shore rubber will draw less amps on start up and kick the machine into action with less power - I agree with this. once its running at 400 rpm having a 12 or 50 kva genny makes no odds.
Max 1 bar pressure for each mt hose is the machines limitations. plus each rotor and stator has a maximum pressure. ie 30 bar (30 mts of 25 mm hose)on a d6 3 . so suggesting you can run stiffer mixes and further is an idiotic statement . youre suggesting people use bigger generators so they can fukk their machines up by running them beyond their capabilities. Completely incorrect - your R/S only run up-to this bar pressure. The D,6-3 from Kachele can run to 80 bar. M-tec R/S also have a higher bar pressure. Running an under powered generator can cause more harm to the machine and thats a fact.
You for one posted on Facebook the other day 'sometimes you just gore get it on thick and quick'. Therefore, you will be working the machine more to achieve the firstly, higher output and secondly the thickness - bit of a contradiction I feel Ian.
now just to prove my point there used to be an issue with k rend e grade in the old days using a d 63 twister it would jamb each time on start up. you had to quickly reverse it and start again and it would run fine until you stopped again.
this was a problem everyone had. A water jet and also a D,6-3 still works with this!
however my friend had a 40 kva genny and never had an issue. so yes a bigger genny appeared to be the answer to the uneducated for a short time until PFT developed and offered the d4 2 clampable stator as an answer to end users in Uk Therefore you have also had to decrease the output of the machine as there wasn't the power to run it! The reduction in the R/S has firstly lowered the output and also drawing less amps thus requiring less power! 40kva is overkill - 20 KVA will be running it like a dream!
. After installing this i could use silicone renders all day long with my smaller genny with zero issues.
so it proves the point that larger gennys are not nessesary.
ten years on things have progressed and Pft have a larger range of similar soft stators. no other manufacturers of stators have followed suit. M-tec have never needed to make a softer shore as there was no need. A soft rubber has been available for years. Can you advise what size generator PFT recommend as we have the old paperwork from them which doesn't state 12.5kva. we never had any issues with K-rend E-grade.
There are similar start up issues with k rend k1 on a ritmo running from mains. however by changing the stator the issue is immediately solved.
It would make perfect sense for the biggest manufacturer of plastering machines to invest in having the greatest range of rotors and stators which they have done
In a forum such as this everyone is entitled to an opinion and i think all machine users who have tried different rots and stats will agree that the Pft original rotors and stators have always outlasted any other stator available.
