Thanks Remy for your quick response. The BDLC motor spec says RPM 2000-6000…but I know on my current Honda/Gesrbox I fitted a reduction to about 1450rpm I think
Building my first electric Drain Jetter
1 - 5 of 14 Posts
Thanks for the input guys. Unfortunately the company who have now developed this 72v 30kwh electric jetter have been very secretive about what motor they have used. It was only my own research initially that went down the path of the BDLC Motor. And yes they do come with an option of liquid cooled/fan cooled. But I’m now going to look into other option suggested….industrial 3 phase….vfd….using DC power supply. I’m not electrically minded. So I’m really out my depth here.
I just want the same spec but run on batteries…without paying $84k
batteries are in series. 3 x 25.6v
here’s link if anyone is interested in seeing what I’m trying to achieve (I’ve got 3 less batteries as this has been massively over spec to jet all day and I only ever jet for 1-2 hr max

Lithium-ion batteries for Van Pack Jetter - MG Energy Systems
Recently Rioned introduced the eCityJet: world's first fully electric Van Pack Jetter. Powered by MG lithium-ion batteries.

Thanks for finding And correcting my statements. 6 unblocking jobs in a day is totally unrealistic for me,It's not spec'd to run all day - not sure what gave you that idea:
"3000psi @ 13gpm (200 bar / 60 lpm). It is ideally suited for use in city centres where strict emission requirements apply and in areas that are completely or partially enclosed.
* * *
With fully charged batteries, the unit can handle up to 6 unblocking operations or run continuously for 60 minutes on full power."

So, you know their continuous flow and pressure spec, which sets your motor size. You also know it runs for 60 minutes on full power on a 30kWh pack which verifies your motor size if you back out pump and motor efficiency.
Their price includes their margins, so of course you can build one yourself for less, especially since there's not much scale for these. Most businesses make more on their time than paying for something that has a warranty and service, and recognize a bodge with downtime a few times a year would have paid the cost difference.
edit: they have two strings of 24v 200Ah batteries that it appears they select, so your statement of 3x is not quite correct. They have 6x as 2x 3s.
And this blog I have never read. Weird how it runs for 6 unblocking jobs or 60mins. So 10mins a blockage….sounds like they have lots of work to get through….
I understand they have margins etc but at the same time I don’t have the finances to justify spending that sort of money. As you seem to know lots more about this than me? Would you mind recommending/spec a motor and pump that would work for this set up of battery?
