Q: Can I charge the battery (1.2Vx2) with the suction tube submerged in the water or do I have to remove the suction tube every time I have to charge the battery?: Since you don't mention the model of the pump, if you can connect the charger with a dry connection, you should not have to remove the pump/tube. If you have to take the battery out, you stand the risk of dropping it in the water putting it back, but obviously (I think) you don't have to remove the pump/tube.

Q: i wanna use a water pump to pump air...but im afraid that it might burn or sth....: the pump designed for water will not work very well at all (any type of pump). its effieciecy will be very low. you will have low volume and low pressure. the pump will also be damaged, making it unsuitable to use as a water pump after its failed attempt at use as an air pump. Why dont you find an air blower? if your experimenting you can find one in every car heater system, so check out the car wreckers yard. Car heater air blowers are high volume low pressure. If you want a big unit get one out of a bus! If you want a high pressure low volume air pump you could use an old refrigerator compressor, or a standard air compressor. hope this helps..

Q: Variable flow variable frequency water pump how to adjust the flow?: Flow plus transmitter control

Q: 1.where is it located and what would I have to remove 1st to get to it. And would I need a torque wrench if so what # would it have to be at when re-installing water pump: 1990 Toyota Celica

Q: So, my husband and I bought a 1993 Chevrolet Corsica a couple of months ago. This weekend we took a trip that ended up being about 400 miles round trip. About 300 miles into our trip, the Check Engine light came on, but there was no noticable problem with the car, no overheating, no clanking or odd smells, the light went off about 2 minutes later. So we got it home, no problems whatsoever. My husband drove it to work this morning, and we were preparing to go to the store tonight in it, and we noticed a massive amount of radiator fluid under the car and the overflow bottle was empty. The leaking appears to be coming from the engine, and the antifreeze is running down one of the upper belts. Could this be a water pump problem? If so, what is the average cost to repair one (I know water pumps are relatively inexpensive, but we'll need to take it in to a shop). Does anyone have any idea? All replies will be greatly appreciated.: It could be the water pump, it could be many items. Rather than just guessing I would take it to a shop and have them pressure test the cooling system and do a block test. We charge 30 dollars at my shop. At that point, you can decide whether it's worth fixing the car or junking it.

Q: 300M head of 11 stage centrifugal pump with 22KW motor, empty (not water) current of 13A, the water into the pump, current up to 44A, open the outlet valve of the current rising to 100A, immediately shut the gate current is up to 170A, the motor stop. Without any problems, not on the impeller pump shaft is not clean the shell the balance sheet, no wear, bearing normal.: The description of the problem is very clear. Most of this kind of circumstance is overload, is also the outlet pressure is very low, the flow is greater than the rated value caused by the resistance can be adjusted by increasing exports or close the outlet valve, reducing the flow resistance increased by less than or equal to the rated flow. Lift is not an influencing factor.

Q: Okay, I'm setting up an NFT hydroponic garden and am now looking for the water pump. I would like some suggestions for one that will give a steady stream at a good rate for the plants. But, it must have a minimum lift of 5ft to reach the first level.I would prefer one with a flow rate adjustment but if you could at least make a suggestion to the GPH it should pump for the right flow after a 5 ft climb I could search more in that range for one I like.Thank you!: I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.

Q: Why such a difference in price. Is the GM worth 4 times the NAPA brand. Both are new for a 2003 Buick ParkAve Ultra with 95k miles. 1st time we're replacing the water pump.: I would go with the NAPA one, the GM one that is on the car now did not last forever either, I have had very good luck with after market water pumps for GM vehicles. 4 hours seems a little steep though......Good luck

Q: The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?: Espa Water Pumps
