Questions about March Pumps answered by the Factory!

[mattd2]

Hi Walter. Looking for a bit of information on the NPSHr for your beer pumps. On you website and a few docs you guys state that when pumping near boiling wort it is important to check the NPSHa is more than the NPSHr (and a general doc states this should always be NPSHa > 120% NPSHr). But I can't find any details on the NPSHr for the general homebrew pumps, 809, 809HS, 815.

 

[WalterAtMarchPump]

On these little pumps its not as critical as their bigger cousins. For the most part on the 809/815 pump as long as you have it flooded you are good.......when pumping at boiling temps the easiest thing you can do is choke the outlet so the liquid coming into the pump slows down and that gives the air bubbles more of a chance to escape before being sucked into the pump. Or just cut the flame...wait about a minute for the bubbling to die and start the pump....you wont loose much heat from the liquid and the bubbles wont be an issue

Walter-
Just had a bit of boil over onto my March 809. Pump was dripping wort off it. I put a fan on it and cleaned up what I could. Pump seems to be running fine for now. Is there a way to take apart and clean it internally? Is the pump going to die on me early?

If you got the motor all wet i would go and get some electrical contact cleaner from places like radio shack and spray it down.....at the very least oil the sleeve bearings with some 3-in-1 oil. Look on the white label for the arrows pointing to the end caps of the motor and it says "OIL" between them....there you will see a small hole on the end cap and a channel leading down to the bearing.

Hi Walter,
I'm in the process of building a large Brutus like system and saw the H325 pump in a recent Morebeer catalog. Can you set me up with a part number for an H325 with the largest impeller you have (not sure if you have a small and large impeller like the 809/815 had), an SS center inlet head and a 6 foot cord?

Thanks for your time.

Pump question, Walter:
Pump has approx. 40-50 hours on it, I would guesstimate.
The motor began to act like a motor, that had a capacitor going bad, ( does it have one?), in that it would hum and slowly turn in a "notchy" fashion, and then finally start.
Sometime it would start normally when plugged in.
Rotor spins freely, and it has been oiled all of it's adult life.
Troubleshooting was done with the pumping element removed from housing.
Model # 809 H S.
Ser.# VV174009

Any pointers, Sir?

Is it possibly "through dealing", and time for a new one?

Thanks for your help, and sharing your knowledge with the board!

It "sounds" like the motor may have been hit or something dropped on it maybe tweaking the alignment of the rotor out of spec.....either that or the bearing on one end of the shaft is going bad....but that's very rare unless there's a TON of hours on the motor. Look at the body of the motor for any dents/dings.....or the endcap for the cover to be pushed in on any section. Ive had some good luck tapping them back out and getting them working again in the past.

Sorry for the late reply...i never got any notification there was a new massage here till today..
Anyway you'd want to ask for the 815-SS-C beer pump and you'd get exactly what your asking for above
our internal part number here would be 0809-0196-0900

Will look closer, as I noticed no dents on the motor body.

As mentioned, she spins freely, but I'll have another look.

Thanks for your prompt response!

 

[Stealthcruiser]

Did a visual Walter, no dents or dings on the motor case.
Rotor has a good bit of end play, which I guesstimate @ about .050 .

 

[Stealthcruiser]

Any more input there, Walter?
The case looks pristine, and no accumulation of wort within.

I don't remember exactly when I got it, can you tell it's age by the serial #, ( above), perhaps?

Hi, I have 3 TE-5S-MD pumps that I bought used off ebay, and I have problems With two of them. The stainless impeller have some sort of carbon that is broken, and the ceramic axle is broken.

The parts needed to repair (New impeller and axle) is very expensive, Could I use a polysulphone impeller on these pumps instead? What parts do I need to fix them that is least expensive?

I use the pumps for transferring hot water from the HLT to the mash tun, transferring from the mash tun to the boiler and for whirlpooling/chilling the last 15 minutes of the boil.

I also use a TE-5S-MD for spinning a spray ball for cleaning a conical fermenter With hot water.

Thanks for Your help

Sorry guys....i'm not sure why i don't get any notifications on new postings anymore...
Stealthcruiser......the serial number tells me when it was built (month/year) but that's not necessarily what we go by since inventory does end to sit on some distributors shelves. If you can, send me back the pump and let us look at at....give me or Wayne a call and get an RMA# so we can keep track of it and i'll see whats going on with it for you.

uglefisk.....you can repair the carbon bushing if you happen to have an arbor press at home....if not then get in touch with one of our distributors and have him coordinate the repair...you can send the impellers back to us direct and we can repair and send them back to you but we don't sell/deal direct so it would need to go through a distributor....
Yes you can use the plastic impeller if you like it has a list price of $57
the carbon impeller bushing is $34
and if you want to change to a stainless shaft instead of the ceramic you can as well....thats got a list of $30 (part#0939-0003-1000)

Thank You, Sir!

I'll box it up this week, and try to mail it out Friday.

Got a number I could call for said " RMA" ?

You can private message it, if you wish.

 

[WalterAtMarchPump]

call the factory direct at 847-729-5300 and ask for Wayne

 

[Stealthcruiser]

Thank you much!

 

[WalterAtMarchPump]

Wayne must be stressin out as of late.....may be the blue moon coming this friday.....if he gives you any lip about returning it to the distributor or such just send it back here to my attention.

 

[Stealthcruiser]

Wilco!

 

[Stealthcruiser]

I'm guessing, that your phone is gettin' blowed up this mornin'.........
Been a busy signal ever since I started trying @ 09:00 EST !

 

[WalterAtMarchPump]

No nothing out of the ordinary here....phones are working just fine....i have had issues from the east coast before though....its weird...i've tried calling our regional sales manager a few times and got busy signals...and notice of the line being disconnected even!! then you call again right after that and it goes right through! I don't know......try calling the 800 number and see if that works....800-323-0791

 

[Stealthcruiser]

Got through around 10:15, got put on hold while trying to round up Wayne, then transferred to someones else voice mail.
Called back, Secretary said Wayne was in a meeting, so she sent me to his voice mail.
Left a detailed message, no reply as of yet.

PM sent to you as of 5 minutes from now.

Thanks!

Thanks Walter, do I need any washers or anything when using a stainless shaft? And what is the part number of the carbon bushing?

 

[WalterAtMarchPump]

nothing changes inside the pump besides what you have right now....you re-use all the same stuff.
Stainless shaft is (0939-0003-1000)
Carbon Bushing is (0150---63-1000)

 

[Stealthcruiser]

Talk to me, Walter...........I sent you a P.M., Sir.

Thanks!

 

[WalterAtMarchPump]

I was on vacation beginning of the week...first day back today....Wayne fixed it for ya...hope is all well now

 

[Stealthcruiser]

Thank you, Sir!

Wayne fixed it up!

You guys are the best, I don't care what those "other" pump folks said about ya'!.............

Thanks, I have ordered this for 3 pumps. It would be very expensive to send the impellers for repair in the U.S. from Norway, so I will try to install them myself.

I found your article http://www.marchpump.com/bushings-replacement-mag-drive-pumps/ nice one!

I don't have an arbor press but I was thinking of using a vise to fit the bushing, and protect it with wood between the vise and the bushing.

Do you think this will work? Does it require alot of pressure to install?

Thanks!

 

[WalterAtMarchPump]

you could do it with a vise at home....only thing i would do if you do it yourself is to make a support fixture for the bushing....what we use here is a spindle that fits the bore hole like the shaft would and with a wide face to support the bushing as its being pressed into the impeller....this way the pressure is distributed evenly across the bushing face and the shaft will help keep the bushing from trying to collapse as its being pressed in....

 

[30Bones]

Can you get poly center inlet pump heads? I don't need stainless, but prefer center inlet

 

[WalterAtMarchPump]

yep you can get center inlet polysulfone....# 0809-0179-0100
