Q: What's the difference between a cold water pump and a hot water pump?: Cold water pump refers to the pump can be transported below 80 degrees C temperature liquid, known as cold water pump, between 80 degrees C to 120 degrees C, the temperature of the pump is called hot water pump.1, the characteristics of hot water pumpHot water pumps IRG hot water pump which is based on ISG and ISW centrifugal pump series on optimization designed, especially IRG type hot water circulating pump consumption, because the pump adopts a vertical motor is installed in the upper part, and a short frame between the pump and motor, not because of a mechanical seal Water Leakage phenomenon the motor inside the water inlet of the motor burn, but also in the IRG based on the design of the hot water pump mechanical seal in high temperature hot water pump maximum temperature by external tap water cooling device can reach 240 DEG C.2, the characteristics of cold water pumpSeal packing seal or mechanical seal rubber material Ding Qing cold water pump commonly used, the most common packing pump is IS single stage single suction centrifugal pump of the pump is also one of the earliest water pump products, because the filler itself requires liquid cooling and lubricating the pump temperature as the only 80 degrees, and packing seal cold water pump and dripping phenomenon has pollution to the pump body pump base and the surrounding environment, this kind of product has been ISG and ISW centrifugal pump series products replaced, ISG and ISW series of cold water with mechanical seal it has no water leakage phenomenon, and is directly connected with the impeller structure used in the the shaft of the motor, the noise and vibration above is obviously better than that of the old type of IS series cold water pump this kind of pump products commonly used in air conditioning water cycle with so called air conditioning chilled water circulating pump.

Q: I have a big garden ,I have plant all kinds of flowers,including roses,Chrysanthemum，but everyday i have to water them one after one pot,a little waste time and waste my energy.who can help me ?tks: If you take my opinion, you can purchase from Powamac, Their services quality are remarkable completely.

Q: So I need to make a human powered water pump... Does anyone know how to make one? Any websites that could show me would be nice.MORE DETAILS:The pump is on the ground...it needs to pump water from a reservoir into another reservoir that is two meters high and two metres across from where the pump is... The pump needs to be handheld too. What should I use and any good plans on how to make it?: The simplest manual pump is the lever-arm pump. This is just an elongated cylindrical reservoir, a valve casing, and a pump chamber in a linear arrangement. A piston within the pump chamber is connected to a link, and a handle which is used to pump the water. You can make a simple one by converting an ordinary bicycle pump. Attach an input hose to the air inlet, and an output hose to the pressurized air output for the tire. A good way to develop plans on how to make it would be to visit your local sporting shop or auto parts shop and look over their pumps. .

Q: Domestic pump automatic shut off the water, but also turn around, stop what happened?: What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon

Q: How to measure the temperature of pump body?: It's the temperature of the pump motor!In addition to large pumps, water temperature is rarely monitored. Even so, the temperature of the pump body will not be measured.Since the water pump pumping, the leaves, vanes and shells are no temperature rise, the temperature is mainly concentrated in the bearing: small pumps rely on the work medium can play a role in reducing friction heat;Heating large pump mainly in the thrust bearing and guide bearing, if the bearing is lubricated by water cooling water, if there is oil lubricated oil cooling equipment specially, temperature monitoring of bearing large pumps can be installed in the pump thrust bearing temperature sensor to monitor the varnay.

Q: hi, how long does the water pump last on e65 chassi 745i (miles): Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.

Q: How do you measure and analyse the pump characteristics and efficiency?: you can ask the question to a motor company

Q: I am replacing the water pump and want to know exactly where the two o-rings go: There are several rubber seals on a water pump. The biggest irregular shaped seal is obviously for the main portion of the pump (this can not be misinterpreted for something else). The next in size is the o-ring for the thermostat. And 2 additional O-rings (one smaller than the other) are for the return pipes. While removing/pulling out the pump, take care that the pipes do not get pulled outward by the pump. And when putting in the pump just gingerly align the pipes to the holes in the pump and you are good to go.

Q: Hi, I need to create a portable shower and was going to go the DIY route, i wanted to use water pumps normally used in ponds, aquariums etc etc as the means of creating water pressure for the shower, the shower need not be really strong in pressure but it should be strong enough such that a person can take a bath using it.height of the shower would for sure be less then 6 feet,question , water pumps are rated at gallons per minute or some equivalent rating, how strong a pump or how much GPM should i be looking at ?: if your sink does not need a pump, you shower won't either....most water systems are pressurized

Q: What is the average life of a water pump in a car?: to many factors to consider such as: materials used for pump, pump design, the engine operator's driving habits. You could have had the wrong belt put on and that would effect pump life. There are just to many variables. I'd say over 60,000 easy. Most pumps come with LLT Warranties b/c you should only have to replace one once.
