Q:Question for you. I'm looking for a 12v (no AC converter, please) water pump to drive up to 4 water misters. Needs to run off the battery, without an AC converter (already found those). The pump will pull from a water reservoir and provide cooling relief on hot days through the misters. BTW... the pump should be reasonably small, limited to a few pounds...If you have any ideas, please advise.Thanks again,Robert

The ac converters are 12V rectifiers so just use the pump (wire to a battery) without the converter or check with motor home repair place

Q:I have a four cylinder ranger with manual transmission. The top pulley was making a squeaking sound the other day and stopping and going. The car stalled out so I had to give it gas for about a minute, and this has happened several more times in the past week. And the car is making a somewhat loud rumbling/clanking noise, which I'm guessing is the bearings on the water pump. So my question is how much will a new water pump cost, I've seen prices quoted on here from $150-$700. Also, it was in the mechanic the other week and I asked him to check the ac compressor and he said it was fine.Thanks

Why not call your mechanic for an estimate? He's (or she's) already familiar with your vehicle. Also, they may determine that it's something other than you water pump.

Q:I want to run 1 HP, 220 v, single phase water pump on solar panels without using any batteries. what do I need to do so amp; how do I wire it?

Hey R, if you have an existing pump you are trying to run that is designed for 220 AC, I would suggest going with the battery and inverter, but either way it will take about 1200 watts of solar. With no battery, the panels need to provide for the surge power to start up the pump, so now you're looking at at least 2000 watts of panel. Then as Caoedhen pointed out, one cloud goes by, it shuts down then starts again, this is not good for pump longevity, so you'll be spending more on replacement parts too. If you don't have the pump yet, and you want to go solar, I would use a slow DC pump, they make them strictly for solar panel operation, no batteries or special controllers. Windy Dankoff probably is the expert, do a google search for DC slow pumps, or look for Windy's website. Then you can get by with a lot less panel, and a better pump for them, plus no batteries. Take care, Rudydoo

Q:What is called soft start of water pump?

Soft start is a form of electronic control, mainly through the soft drive to achieve. Principle: the former contactor is directly started as contactor, first pull in, and the device is started by soft driving. Soft start device start smoothly, starting current is small, control system life is long. Soft start is now in widespread use. But the use of high-power equipment is less, the general current is less than 120A.

Q:89 Dodge van overheats, no water leak, replaced thermostat but still overheats.

this sounds more like a radiator problem, or possibly an electric fan, if there is on. Usually the water pump will lose the weep hole gasket on the bottom of the water pump and dump water when its running, but quits when you stop. A water pump bearing can start to sieze, you may notice temp fluctuating almost to hot, then drop back down. Take off the radiator cap when the vehicle is cold and start it up. let it idle until the thermostate opens. and watch the water in the radiator to see if it circulates at all as someone slowly raise the idle up to 2 thousand rpm, and rev the engine a few times, and see if the coolant momes across the radiator. It may be your thermostate is stuck partway, or the radiator is ready for a rebuild, they generally are good for about 20 years or so. I suggest using distilled or filtered water in your radiator if you replace it. There are many harmful chemicals in tap water, much more than people realize, and they can combine with chemicals in antifreeze and cause solder rotting electrolysis. By using distilled water, you minimize this risk and studies by major radiator companies have been proven to make radiators last a lot longer if a minimum amount of care is taken, like changing antifreeze every few years, and using distilled water as much as possible. I buy mine in the gallon jugs. and top off the overflow occasionally.

Q:I have a 2000 dodge 1500 the water pump is leaking and the belt is real squeaky. Are these related?

pump quites or slows causing overheating or heat increased in the motor causing the belt to wear more on the hot pullys get a new pump or fix it and just replace the belt

Q:We use this water pump for about 2 years, and in the last week the circuit breaker trip when we turn on the pump. What should I check first for the problem?

Is it a circuit breaker or a GFCI that is tripping? If a circuit breaker then the pump motor could be frozen or is binding, circuit maybe over loaded because there in now something else plugged into it or the circuit breaker is wearing out. If it is GFCI (and on a pump it probably should be) then you have a ground fault condition in the pump motor or the wiring. In which case I would suggest hire an electrician to sort out the problem.

Q:looking for ideas and info to build a simple and rustic wind powered pump for a backyard pond. I don't want to use any elecricity and I would like to create something that once its made, will be trouble free and simplistic in operation. I esp. want info regarding the vane design and the method of drawing the water. I would appreciate any web sites, but I don't want to buy any pre-designed thing or plans.

My Grandpa could show you one that was installed in front of his house about 90 years ago. Check out a farm ranch supply store. Those guys are freakin geniuses.

Q:What are the export pumps packed in cartons?

Upstairs said the basic right, but only limited to the domestic, export also put the pump's wooden case (frame) into the carton.

Q:What is the difference between self-priming and non self suction?

Self suction pump, pumping water conservancy machinery used, composed of a pump body, a rotating assembly, leading assembly, trash cover, and inlet and outlet pipe, a blocking net general assembly; start the motor, dynamic linkage, rotary assembly in promoting the impeller centrifuge, bubble up surging, generates suction. The air inlet pipe, the outlet pipe from the pump body, air exhaust, water outlet pipe outflow, the water pump, excellent performance, deep suction lift, large flow operation, saving time and labor, is the most excellent mechanical pumps in the realistic society.1. self suction pump, as the name implies, pumping tube is under the condition of air, use form a negative pressure pump at work (vacuum), under the influence of the atmospheric pressure will be lower than the water pumping port, then discharged from the pump discharge end. Before this process, there is no need to add "diversion water". The pump with this capability is called a self suction pump".2., some centrifugal or rotary vane pump, before absorbing water, you must add "water diversion" in the pump cavity to form a closed environment, and then pump operation to form negative pressure, to achieve the purpose of water absorption. For example, a manual pump used in rural areas. No self-priming capacity of the pump, each time before adding water to add "water diversion", it is very troublesome.
