NOTE :3phase dc is completely different with 3phase AC; 3phase DC means 3 pairs of magnetic polarity & sensor-less, power supply the same with common DC pump(two wires: positive and negative). Intelligent program-driving, sensor-less,PCB board outside (main factor that pump can be high-temperature resistant)

Q: I am planning to make a overflow box for my 55 gallon saltwater tank and need to know whats a good pump to get the water back up???: Rio pumps are inexpensive and are very very durable. I highly reccomend them. I keep my sump level fairly low so that when i see bubbles in the display tank cause the pump is sucking a little air, i remember to add top off water. My pump sucks air about once every other week prolly for a few hrs at a time, until i get home from work and its still going strong! (I know this isnt the best way to do it, but if i dont run it low enough for it to suck air i totally forget to add top off water). I havent had to replace the pump yet. I also replaced my outdoor garden fountain pump with a rio. It sucks up leaves and junk all the time with no problems (except when the leaves cover where it sucks the water but thats not the pumps fault lol)

Q: are there any pumps that can save energy more? Environmental protection is necessary and the price is not high.: Water pump. ( Pond ) Sump pump. ( Flood prevention ) Auto water pump. ( Radiator ) What is the specific purpose of the pump.

Q: ok some one put sugar in my gas tank i had to replace my fuel pump and now i have sludge that's eating th inside of my radiator hoses and my water pump went and of course that's timing driven and my timing belt is awful tight i cant put a finger in between it ....and my car is not car water so i cant drive it and i don't have money to blow to take it to a shop any help u can offer will help and i know i am going to replace my water pump and info for when i do that will help and answers to the sludge (its like a Vaseline) and how to find out if its in my motor or my brand new radiator ? me plz i am a 18 yr old girl with knowledge about cars and have friends to help me and my mom so any helpp will help and is better then none: Correct okorder /.... Sugar in the tank, is a MYTH. The problem you have, is NOT due to someone putting sugar in the tank. Secondly, your fuel system doesn't connect at all to your radiator. So, replacing a fuel pump has nothing to do with sludge in your coolant. So, is the sludge in the coolant, or the fuel? Because honestly, your question makes no sense right now. Edit: I didn't correct your spelling. I corrected the fact that you are incorrect about sugar in the tank doing anything. IF anything, it would have clogged your fuel filter. Not your fuel pump. Go read the article.

Q: I had to have my water pump replaced on my '95 Saturn because the car was leaking coolantFirst, why does the coolant leak with a bad water pump? Second, I paid $250 part and labor. Did I get screwed or is that pretty fair?: Saturn Sl1 Water Pump

Q: i took off the water pump cover on my 1986 cr 250 and discovered that the impeller wont come off. ive tried turnig it the wrong way and the right way. can someone please tell me how to get it off.: Remove the water pump cover, Now you will see the impeller and it has a little 10 mm(I think) nut fitting on it. Put the bike in gear and apply the rear brake. Now unscrew the impeller with a socket wrench. Take it easy as they are quite soft. Once that is off, you should be able to pry the seal out, and pop a new one in. A good way to get old seals out is to use a screw, screw it in to the seal then grab it with the pliers. You might want to replace the oil seal while you are there since they are so cheap. To do this though you will have to remove the rh crank case cover cause this seal sits in the inside of this cover. This is also an easy job. When you remove the rh crank case cover ( with impeller already removed) the water pump shaft should just slide out from the inside and give you easy access to both seals.

Q: I think its the water pump, I fill the coolant with water everyday and it is empty once I make it to my destination.: I know this isn't exactly what you asked but if you have the v6 engine changing the water pump on this car is a very easy job. There is a video on youtube that shows you exactly how to do it, just search water pump gm 3.1. Just be sure to get all of the old gasket off and use rtv on the new gasket. You could probably change it yourself for less than $50 and 1 hour if you can do basic car maintenance.

Q: how often do i need to change a timing belt and water pump on my car? also, how much should it cost? should i have it done at the dealers or at a small mechanic shop if i chose to? which would be best? what are steps when having timing belt change?: check the ads in a free paper like the LA weekly or SF guardian. they always seem to say when you should do it and what they charge. the water pump shouldnt be much extra (100?)since they are already doing the timing belt. call a mechanic you trust and ask them. If you do not have one then ask your friends who is good. the dealer will rip you off on price, it can easily cost double there would you rater pay someone inexperienced at the dealer $100 per hour or someone who has done it for 40 years $60 per hour and he does it faster anyways (so it costs less)(and they take pride in their work)(and they will replace other parts that need it for cheap and leave pieces that are still good because they know) The dealer might charge you for 6 hours because the book says that even if they only spend 4 doing it! a VERY rough guess would be 600+100 for water pump you do not need to replace timing belt very often. I am thinking 60,000 miles. look up in owners manual or shop manual for your car for replacement interval. good luck

Q: I have a slight idea but I would like to see what steps other people have taken. I have a 1992 ford escort that needs a new water pump, what steps have you taken to replace it?: if you're going to do it yourself first I recommend getting the book for the car sometimes the library will have them..you also want to be careful when changing the water pump because your timing belt is hooked up to the water pump. If you misalign the camshaft or the crankshaft pulleys or turn them independently when the belt is off you can cause damage to the head of the engine (very important: your timing will be off..you don't want that). To start with though, you will have to take off your accessory belt and the accessory crank pulley, then take off the timing belt cover and use the crank shaft pulley to line up the marks that are on the pulley and the engine (on both the crankshaft pulley and the cam shaft pulley) carefully take the timing belt off (replace the timing belt and the timing belt tensioner..trust me it'll be worth it). You're going to have to drain the antifreeze before you take the water pump off. (I would also replace the thermostat because its cheap and you already have the fluid out) The install is pretty much the opposite. (again make sure the marks line up on the cam and crank pulleys and don't turn them independently when you're putting the belt back on) (short answer: get the book and/or have someone that's done it before help) when your done you can say you did it :)

Q: i have a problem with what i think is my water pump, and i was wonder if anyone had any websites that have free engine diagrams, and if it is my water pump, it turns on and off when at idle, is that normal, if not, what could be the problem?: How to tell if you have a leak do this a dusk look to see if water is coming out of the sides are at the bottom. use a flash light. If the car is running HOT its possible that its you water pump You can have it pressure Checked.

Q: I have coolant leaking out and i'm pretty sure now that it is the water pump. Question can water pumps leak even if the cars not running?Like a steady drip every two seconds? Forming a decent puddle after awhile, but when running the pump is'nt making any abnormal noises is that normal? Is there other clues to positively know the pump is bad? I cant believe how hard a job it looks like it would be to replace it there is no room! Anybody with some helpful how to's? how about an estimate on how much a shop would charge to do it?: I have a 94 grand am with the 3.1 v6 and really it's an easy job, it looks harder than it is. The biggest thing is getting the serpentine belt off.
