FAQ

Today I was installing a new water pump on my 1999 grand Prix. When tightening the bolts one of them snapped off. Now the pump leaks from that broken bolt. I was wondering if I would be able to stop the leak using some sort of sealant or would I have to take the car in to get the bolt removed?

You will need to remove the water pump and see how far down the bolt broke. You may be able to get hold of the bolt with vice grips and get it out. Worse case you will have to drill it out and re-cut the thread or use a bolt extraction tool, you simply drill a hole smaller than the bolt and the extraction tool turns the opposite way to the bolt thread and as it gets tight its meant to loosen the bolt in question. I have done this many times and it dose not always work so you may need a professional to do it.

If a person took a water pump and attached to a hose and ended up with (random numbers) 15 gpm and 30 psi at the end of the hose, what would happen if you put an exact same pump right next to it and hooked the two pumps together with a quot;Yfitting to a single hose? Would both the gpm and psi be doubled, or neither, or just one? What would happen?

Any discharge piping system down stream of a pump (in this case a hose) will have a pressure drop that varies with flow. You can develop a curve of this pressure where flow rate is plotted against pressure drop. Any centrifugal pump will have a performance curve. The lower the discharge head (pressure) the more the pump will pump. The higher the head the less the pump will pump. Assuming these are centrifugal pumps then their performance will balance with the system pressure drop curve to seek a point on each pump's operating curve that matches the overall system pressure drop curve. In other words the pressure will go up some and the flow rate will also go up some but neither will double.

I've searched the net but cannot find exactly what I'm looking for and hoping someone out there can steer me in the right direction! Maybe I'm not looking in the right place....or do I have to fabricate my own? I'm up for the challenge!1) Trying to source a water pump that I'm going to power by HAND or a BICYCLE. 2) My choice of pump to give a continuous stream of water (very important) is a rotary (centrifugal) type or is there something else capable of a continuous output?3) This will NOT BE USED for potable water. SPECS:a) lightweight but durable, the smaller, the better. b) low RPM, high volume output and capable of producing/handling pressure. c) self-primingd) able to handle some small particulates in the water as I am using rain water. (from outside, NOT filtered, so the following may be present: bugs, dust, etc...) Thank you, in advance, for your help and would be nice to thank the individual(s) for a unique answer to my request at a later date so let me know you're preferred method of contact!

There are very small rotary water pumps designed to be driven with hand-held electric drills. These pumps may be purchased in some hardware stores or farm supply stores. One could be adapted to a bicycle- type drive. Small pumps have about a 50% efficiency so you would need to produce sustained muscle power applied at around 150-200 watts to achieve 75 -100 watts of effective hydraulics. Applied watts = (GPM) (PSI) / 1.277 million (eff.) Where eff. is as a decimal. Edit : A 3/8 drill will pull about 280 watts. I can do 200 watts on an exercise bike, but not for long. I am a 79 heart patient, so you can probably do better..

no water is running my deep well pump kicks on every 15 min. it runs for 1-2 min when it kicks off then a noise like someone threw a ball against the house. can you help

check the back flow preventor sound like it might have trash and or build up casing it to stay in the closed position and when your pump turn off you hear that thud like sound due to the pump having to be slammed it reverse do to pressure build up.

what is the actual capacity of 15 stage 1 H.P. Borewell submersible pump. I mean can it draw water if it at 300 ft depth. Is 15 stage 1 H.P pump capable to draw water

How to remotely control submersible pumps?

Now the remote control of submersible pumps and pumps is very mature, and the cost is relatively low. We use the Ji'nan Huichi electronic pump remote controller controlled step-down start control cabinet, convenient Clockwork SMS can control the pump start and stop, and return to the working condition of the water pump, water pump overload or lack of power can also feedback fault message to the responsible person

I just had my water pump/timing belt replaced and oil change. When the pump failed, white smoke was coming out, which I figured out to be coolant from the smell. Now there is smoke coming out from under the engine, which I believe to smell like oil. Also, the temperature gauge goes up to the halfway point when I am at a stoplight or idling. The highest I have ever seen it is at 1/3.I had my car serviced by the dealership and I asked them. The man said its burning oil residue from the oil change and that it will burn away in a few days. Is this true? I have had my car worked on and oil changed for the past year at this dealership and have never had any smoke or other problems. What else could be going on? Worse case scenarios. Thanks everyone.

Oil residue ought to go in a few hours, not days !!! Anyway, if the smoke persists then it seems that youv'e got a cracked engine gasket and oil is mixing with cylinder water. Check it and check your radiator for any clogs.
