Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q: If I increase the power of the motor, must I also increase the power of the inverter?

Q:I just noticed a slight leak from my water pump. About the size of my fist. I called one mechanic and was told the 2001 BMW Z3's water pump seals are tight and do not leak with the car is running (engine is hot) but once the car cools the water pump seals expand resulting in the small leak, that I shouldn't worry about it unless it leaks more, the engine over-heats, or dash light turns on. The BMW said I should have the water pump replaced but he may have just said that to make a repair sale. Anyone out there know the truth?
Rarely do BMW water pumps leak a lot. Most would not even leak when pressure-tested by a mechanic (for a few minutes). But a leaky pump would leak when the engine runs and specially when it is pressurized and allowed to sit overnight. Usually the seal itself does not cause the leak. It is the wornout bearing which allows the pump's shaft to wobble and thus allow coolant to leak. Overheating due to air getting inside the cooling system is big trouble. But bigger trouble still is a catastrophic failure due to failed/seized water pump bearings. Have it replaced. And the previous statement that your car is about due for hoses and thermostat replacement is correct. There is even a chance that the thermostat is allowing the cooling system to get over-pressurized and thus results in coolant leaks. Replacing the pump is good, replacing the thermostat in addition is better, replacing also the hoses is best. If you can afford it.
Q:We lost power during the hurricane, we have well water. the power went out and we lost water also, what are the procedures to bleed and restart a goulds pumps c48a93a06 water pump?
1. you are going to need at least a couple gallons of water in a bucket to re-prime. 2. look for a plug at the top of the pump and remove it. 3. pour water into the plug opening, filling up the pump as much as you can. 4. put plug back in so at least one thread is grabbing. by doing this it will allow air to escape and won't be spraying water everywhere. it is also a good idea to keep your hand on the plug. 5. turn on electricity to pump. 6. when you start to notice pressure re-gaining tighten up the plug so it does not drip. It is also a good idea to have an outside tap on to get air out of the lines. Another thing is, it is a good idea to shut off water to toilets and washing machines before re-starting pump because small debris have a habit of clogging them up. When your pressure is back, drain your toilet and cold water line to your washing machine, flushing all the stuff out until you see nice clear water. Hope I helped and good luck.
Q:When I buy submersible pump, the other party did not inform is the aluminum submersible pump, water pump factory production of aluminum submersible pump illegal? Is it against the law to sell the pump to the pump without informing me?
When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
Q:Submersible pump coupling, what does this coupling mean?
Submersible pump, mostly in sewage sewage pump, this is more common, QJ submersible pumps generally can not use coupling devices
Q:If I were to go to a shop, how much would it cost to replace my water pump? It's a 4.0 6 cyl engine.
$70-$150 +cost of pump. Most shops have certain maintenance hours for certain jobs. Call around for exact pricing. Honestly, if you have a sockets (metric) and wrenches you can do it yourself in about an hour or two, maybe less. You don't have to mechanically inclind to replace the water pump on the 97 Wrangler. If you do it, I do recommend buying a Haynes/Chilton's book if you don't really have a clue. If you need to buy the tools, book, pump (gasket should come with it), water pump RTV, and coolant. That will still be a lot cheaper than paying somebody. Plus, you will get the joy of doing it yourself. Also, you could put the savings into a high-flow pump, vice original equipment.
Q:We have a 3-story (including ground floor) house. We have 2 bathrooms.We need to invest in a water pump to deliver water from ground floor to all floors + 2 reservoir tanks (one located on first floor, and the second tank located on the second floor).Which water pump do you recommend among these:(1) Valco 261PL or Valco 261PT(2) Davey HS50-05TI'd be MOST grateful if you could kindly advice me on any reliable brand that you know (apart the ones that I mentioned). We're basically looking for a very reliable pump up to around $700 (preferably less).BTW, according to you, what's the typical horsepower we should be looking for? Will 1hp suffice??Thank you very much!
I've never heard of those brands, but your TDH is going to be approximately 25 feet (ground to middle of the 3rd floor) plus 92' for pressure (40 psi). Ad at least 5' clearance head and that's 122' TDH. That's also 53 psi, meaning you'll want a pump that with an on-off of 40-60 psi. A centrifugal pump will do that. You'll probably want a minimum of 5-6 gpm. See if you can find a pump curve for the pumps in question and follow the vertical and horizontal lines on the chart and see if it will produce 6 gpm (or whatever volume you want) @ 60psi. Keep in mind that you can compensate for a pump that's a bit shy in volume with a larger pressure tank. Chances are most 3/4hp pumps will do what you need. If you don't have a pressure tank already or don't want to plumb a separate tank to the pump, look for a pump/tank combo. Then all you will have to do is plumb an intake and outlet line. A very good and very reliable American made pump like a Meyers should be way less than $700. The pump itself will probably be half that and a separate pressure tank approximately $175. Steer clear of Chinese made pumps. They may be ok, but finding parts like seals can be nearly impossible. Spending a couple of hundred extra dollars for an American pump will be money well spent when it's still running trouble free 10-25 years later.
Q:My car is overheating and i don't know why just trying to rule out as many options as possible.Things it is most likely not: blown gasket/cracked head, both replaced 2 years ago and no tell tale signs I will be doing a block test soon, thermostat replaced it and put the old one in hot water and it opened, hoses replaced with new one two years ago, no leaks pressure test a few days ago. Things yet to be ruled out The radiator being clogged or not allowing good airflow, water pump impeller failure.
If the water pump impeller fail your heater will not work properly because the coolant is not circulating .If coolant is low or restricted heater core will result more or less the same condition.However overheating can be cause by timing too.Blown head gasket can be verify with compression test.Water pump can leak while you are driving and may leave little to hard to detect trace of leak.It can pissing for a few seconds and stop for a while. Do not over look the pressure cap.It can cause overheating symptoms boiling over the recovery tank.Plug rad will definitely cause that.The cooling fan -if electric can be faulty. Some has a module or relay activate by a temperature sensor.Some has a temp.sensor sending signal to the COMPUTER and the computer turns the e-fan on or off.If any of those components is faulty.you can have overheating problems.check it out
Q:Is it a good idea to turn my pond water pump off at night and back on during the day to lower my electricity bill?
You have a few issues here. Your water that leaves when it's turned off - that's part of what's called your 'water in transit', the problem part is what can't be contained by your lower vessel when turned off. A surge tank can remedy this, as can other solutions - but I'd have to see it. Leaving it on 25/7 can eliminate this effect - until someone has to work on it. Off or not - if it is a sterile pond, you may only need 4 hrs a day for the sanitization, if your circulation is proper. If its a single pump setup, then override the timer to get the look (if you have a waterfall or fountain) when you want it. If it's a live pond, then it really needs to run all the time. These points are all part of a proper waterfeature design. Unfortunately, in this market, lots of folks and others are creating things which have the attributes you describe - and plenty more. It's like the professor of Landscape Architecture at the University of Arizona said, 'A waterfeature that is not properly designed and/or built is a planter waiting to happen'. Good Luck!
Q:I have a 99 Olds Intrigue With the 3.8L (Vin K) engine. I have a belt driven water pump, but i was wondering if there is a fuse or relay that is associated with this water pump. I remember knocking a fuse out on accident while changing my radiator and now the water pump appears to not be working
