March Pumps

[Bru4u]

I got 2 of 809HS and they are rated for 250 deg F = 121 deg C

Anyone have any experience of these pumps..?

Nope, do you have a model number?
Apart from temperature rating, make sure they're food safe and they should be alright.
I also have 2 March pumps like Bru, can't go wrong with those pumps

Hi, thank you for the reply.

The reason for my question is, I have found a range of very quiet, mag drive pumps made by a japanese company called 'Iwaki Pumps'. They're very good quality but, only rated at 80 deg C though...

Anyone have any experience of these pumps..?

Regards.

I have seen Iwaki pumps used in very expensive quality measuring instruments in the petrochemical industry. These ones were magnetic drives and very well built but I couldn't tell you what temperature they were rated for.

Any links or pics please - would like to see what it would cost to get them here. Thanks

I can't see anything obvious regards not being food grade, all looks good, but to be sure I'd drop them a e-mail :thumb:

Happy days then :party:

Strangely enough, I came into work tonight and this was waiting for me:

Unfortunately I have to fit it to a machine though But I do have a manual now if anyone wants to anything about them.

I have read the PDF, which is available on their website.

I notice they are either made from a very interesting new biological plastic made from a well manicured lawn somewhere or the japanese original has been translated into english in a, how they say it, rather than how its written manner.

MD series handle a wide range of chemicals" :rofl:


Although polyprop is considered food safe, read this before making an informed decision or purchase.

Silage, much better than plain old grass
To be honest, I'm not sure but I understand them to be food grade plastic

I've looked at this quite a bit and you cannot avoid the stuff :shock: which is very worrying, as nearly everything is packaged in it. The March pump, used very infrequently for brewing, doesn't worry me too much.

What material are March pumps made from..?

Polysulfone see here :thumb:
If you want a stainless headed 809 see here though it will be expensive.

I dropped lucky with mine (not a March but all stainless & better IMHO)

£45.00 plus delivery, I wish I had bought more at the time.
My March pump on the right of the picture (doubles as an Underback)

was also a bargain at £45 new of fleabay & doubles as a Rims Underback (but does suffer from a polyprop head).Look at This one on Fleabay, I could have bought 10 at the time for the same money I paid for mine

Is that a RG550 Shane, looks like it :hmm: If it is you can't even begin to compare it to the March 809, the 550 is an animal :lol: great pump

The rg550 is an absolute animal, I can testify to that!! It managed to collapse the conical stainless false bottom in my bolier yesterday!

I have already put a bypass loop in to slow the flow down from the 30-40 ltr/min that I would get with a 1m head, but I now have the problem of a powerful suction caused when the false bottom is covered with hops etc following the boil.

I am now considering slowing it down electrically with a triac. Does this sound ok, or does anyone else have any suggestions?

 

[Vossy1]

What is the flow rate of a March 809..?

Depends on a lot of factors really, if you want unrestricted rates look at the March webby.

I've seen a lot of people using these pumps but, they always have some form of flow restrictor valve in series to limit the flow.

TBH, the chances of getting a pump that has a flow rate exactly that you require is next to nil, hence folk using a flow restriction of some type.
