how hjgh will it pump

I have it set up to pump about 5 feet to the sewage main but it is very powerful and I think it can definitely pump much higher than that...maybe 10.

Yes this pump is designed to pull about 27 - 29 inches of Hg That's a whole lot more then 2 MM of Hg.

A small submersible mag drive pump about 175-250 gph should be fine. thanks! Steve

It would work. But I think u should go to 500 gph or higher. These pumps were made to pump short distances

I have used the HC8000 for a couple of years with a 1/2 HP pump and no issues.

Depends on how long you pump. It's not very long though. I think I prob got about 15-20 pumps at 15-20 min.

Carl G I would like to know why you needed an oil lubricated pump? Changing to wet rotor may be an issue because of the clearances...if it stops it might only a small particle...I once had some system "goo" hat stopped one...it took washing it out with diesel to get it back running. Both engineering submitals indicate the NRF22 is about 2GPM less than the LR20BF at 10ft head...so here's the thing...depending on what system youre installing it on...most systems were designed for 160f DHW or 180f HWH water so by putting this in (I dont know your system but I would do it) you'll have a slighting lower flow rate...in DHW who cares as its no big deal...BUT in a HWH system your control valves will open more and this is a seriously good thing in modulating valves. There will be a larger delta T so I'd also lower my boiler temperature by at least 20f assuming youve some form of condensing boiler...this will help ensure youre in condensing mode. Circulate fluid...not temperature and you'll save a lot of money. Make sure your side stream filter is clean and check it a few times in the first 1-2 months because the more flow means the more crud is likely to get back to your HEX...if there isnt one put a Y strainer in and add a "sock" on the screen for a month or 2). A possible problem is how many zones open/ resistance decreases across too many different circuits/ zones...too many and there wont be enough. The system I installed this on it is actually the primary circulator through a 2xwall HEX serving the HWH off the DHW system...it works so well Ive been promoting it/ its been installed on 3 systems in this last year (its not my J.O.B but I do design energy and conservation projects as is my profession). Last, make sure the expansion tank is on the pump inlet side/ the return (DHWR or HWHR)...these high speed pumps cannot handle even a minimal bit of cavitation. All the best

The 4400 GPH pump is 1/2 HP. It will handle 10 ft lift just fine (3200 GPH output @ 10 ft lift, according to the specs). I have it lifting 12-14' in my basement.

Tony, I take mine up to 100/105 plenty gas left over. I am sure you can do it. It is so controllable that it doesn't freeze immediately. I tossed my frame pumps.

Hi I have a one hp 220 I pull 80 feet it holds 60 psi great pump so farsteve g

No check is necessary. You should expect to see around 20 gpm. See the curve in red.http://www.tsurumipump.com/prods/submersible-pumps/single-phase-pumps/hs-series.aspx

A Grey Beard Pump initial draw on start up is 1amp. After start up the draw is .5amp. Thanks for your interest in our pumps. Regards Grey Beard...

it will go up to around 30 psi, which is pretty good for this pump. I use this for football games to ensure 12.5-13.5 lbs as required by the rule book.

Bonnie - 1/3 hp. It will hold 28 to 30in Hg in smaller sealed systems, such as automotive AC. Note that vacuum in this unit is constant and increases up to about 30in Hg. The equivalent in PSIa (a = absolute) for 30in Hg is roughly 15 PSIa. Note also that you will require a vacuum gauge to monitor vacuum; not a pressure gauge. Hope that helps.

That depends on how high you plan on discharging as it won't pump from the floor lets say out a basement window to much lift for this pump

Honestly, I'm not sure. I'd have to dig up my pump to see. But, I can't overstate enough - this is an inferior pump. I was thoroughly disappointed with its performance. And, I called the manufacturer and walked through trouble-shooting over the phone - my pump wasn't defective in any way; it's just a poor pump. I strongly recommend the Medela - there's a reason everyone else does.If you're really interested in the Hygiea - I'll sell you mine for cheap - it's just collecting dust in my closet.

i takes a lot pumping.i use it for my motorcycle cause its light but i do have to pump to 35 ils.if you have a car get a electric
