Q:should get oil pump seal and valve seals replaced if getting a new timing belt & water pump?
Yes do it. As long as your in there. I do the same thing and recommend it also. You have a good mechanic man that seems to know their stuff.
Q:I'm looking for a salt water pump...?
If you live the ocean try the shipyard, or any ,were around dock...or online..
Q:Automatic water pump!!?
WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....
Q:Safety head of water pump?
The pump achieves this by providing sufficient energy to the liquid at the entrance of the impeller, and ensuring that the liquid remains liquid. This energy is known as the available cavitation margin, referred to as NPSH (A).If there is not enough NPSH (A) or energy, as soon as the liquid enters the impeller, its velocity is increased. According to Pohl's law, the pressure drops. A reduction in pressure will cause some molecules in the liquid to become gaseous, forming vapor bubbles.The performance of the pump will be lowered immediately and the bubbles will continue to grow until the pressure inside the pump causes them to implode.In brief, it is to avoid cavitation.
Q:water pump replacement 2000 Plymouth Voyager?
This okorder.com/... Look on the front of the engine and see if it is there with a pulley and normal belt on it.
Q:Water pump runs a lot?
No, sounds like tank is water logged. Turn off pump, drain tank, replace plug and prime pump. It needs air to pressurize, water don't compress. hope this is a quick fix for you.
Q:Well water pump runs constantly?
You probably have a problem with your pressure tank. If it is the bladder type it could be broken. If it isn't it may need compressed air added. A faulty pressure tank causes the pump to run constantly every time water is turned on in the house. You need to get the tank repaired if possible or replaced. Failure to do so promptly will soon burn out the pump from overwork. If it runs even when water is not being used in the house then this is not the answer to your question. But if it goes on every time you flush a toilet or use just a little water it probably is what is wrong.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
Q:Need a new water pump, should i get an electric?
Get.the.normal hose then think bout what you need to do
