Stainless steel Vertical Multistage Centrifugal Pump

1.Introduction:

CDL/CDLF water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?: 60Hz pump and 50Hz pump itself is not much difference, just that the motor speed, the rated speed is 3600 rpm, 1200 rpm, 1800 rpm, the latter is generally 3000, 1500, 1000 etc.. If it is to use the same pump, the difference is that the 60Hz motor pump flow is 50Hz, motor water pump flow of 1.2 times, the lift is 1.2*1.2=1.44 times, power is 1.2*1.2*1.2=1.728 times. So in the actual manufacture, especially some relatively large flow lift pumps, pump motor using 60Hz to use 50Hz thicker than the spindle motor of the pump impeller, the difference between the two, in addition to empty size shaft is different, what basically no difference. As for the data of package angle, the water conservancy models of different factories are different, but I don't know whether there is any difference between them. Most of them make no difference. However, if you want to use the 60Hz pump to achieve the same flow rate as the 50Hz pump, the impeller of the former should be cut to 0.833 times the size of the latter.

Q:my nissan 1993 maxima SEthe AC is not cold at all this year it ran perfect the year beforecan the water pump pressure really affect the AC?how much should a new water pump cost for my car?: You must know water pump is for cooling your motor ,by moving water around inside , AC has a pump or a compressor , Inside is a gas , under pressure the gas get cold when the cold lines are put in a space with a fan it makes cool air for you inside your car!!! All you may need is some more cooling gas for your AC pump

Q:I am planning to build a koi fish pond, and I know I need a water pump. All I know is that a water pump will circulates water. Does it do anything else? does it act like a filter? does it provide aeration or oxygen to the pond?: Get a pump which could drift, the two with an equipment which you are able to purchase or droop it with an inner tube or on some blocks or the pump will suck up debris from the backside or your lake. Use the biggest pump you have got sufficient funds and be constructive to have a GFI to plug it into. What you want to do isn't consumer-friendly, yet it quite is a possibility. Attaching a hose to the pump intake isn't consumer-friendly. purchase your pump at a plumbing furnish domicile and clarify what you want. they are able to have each and every thing you want and save you countless journeys back and forth to a large container save.

Q:as i asked before in my question what needs to be fixed when a water pump goes bad. so finally it went bad today the car leaked all coolant and for some reason all the blades on the fan broke and the battery light came on. which is connected to the alternator belt so thats not the problem. so now does anybody have any idea how much it would cost to fix and by what i know it needs a new belt for water pump and new fan and water pump etc. taking it to mechanic monday but wanna get an estimate first from u people. any ideass thanks: Oh you found one doe 60 bucks good for you. Lot cheaper than the dealer quoted you. When a water pump job is done the fan and belt are removed anyways. So all you will have to buy is the new fan, the belt if you want. The other parts you listed are probably fine. The tech will inspect them when doing the water pump (if he's on top of things) and he'll let you know.

Q:i need to know an estimated cost for changing this cars water pumpthanks..: Too okorder i did this, and by doing so it saved me money, time, and the risk of getting ripped off.

Q:Hi I really need a USB water pump (small). I have found one in China but they need payment in a different currency so its proving difficult. I would much prefer a US/EUROPE seller. Cheers.PSgt; If I had to pay to get the power supply changed from wire to USB then I could if anyone knows who could do this.: The USB output has a 5V power supply. USB2 delivers up to 500mA and later versions may be 900mA. USB hubs start off with less than this (100mA) but change as they are initialised. Some dedicated USB charging ports supply up to 1.8A. There are some USB power cables that take the output from 2 ports in a sort of Y harness (first link for example). The result of all this is that only a very small pump would run from most USB ports. I did find 2 rated at 5W and 8W but the voltage was not shown. I suspect they were mains operation, meant for large water bottles. If they were 5V they would use 1A and 1.6A respectively, so only run from special USB charge points or double cables, and only in some cases anyway. I assume you want to run from a Laptop/Notebook battery for convenience. The point is that even if the USB port can supply the correct voltage and current the battery would be emptied very quickly. It is probably cheaper to get a suitable pump, then power it from a separate and more suitable rechargeable battery or mains adaptor (wall wart), whatever it takes, taking into account how long it should run with a single charge. This is about the battery voltage and the capacity in ampere hours - the number of hours it can supply a given current. D size rechargeable (Ni-MH) would run a 6V x 6W motor using 1A for about 6 hours. C size cells are half that, and AA cells about half again. It takes 4 cells to get 5V. Get them as a pack though or at least with a battery holder, as they cannot be soldered. Then you need a proper charger. Recent laptop/notebook batteries are lithium ion types, 10.8V and 4.8Ah, so deliver 1A @10.8V for 4h more or less. Other types worth considering are for cordless drills.

Q:I have a 2002 Honda Civic Ex sedan with about 105k miles. Sometime before 110k I need to get the timing belt replaced. At about 95k my mechanic asked if I wanted to replace the timing belt and the water pump. According to the owners manual the timing belt must be replaced, but it simply says check the water pump.I don't want to pay for unnecessary repairs, but I also know that both of these jobs are quite involved, but can be done together fairly easily. Is there anything I can do to check myself or do I just have to trust my mechanic when I take it in. Also, what is the cost difference between the timing belt job and adding in the water pump at the same time?: If you're going to have the timing belt changed you might as well change the water pump at the same time - it would take about the same amount of effort and cash in the future to just replace the water pump alone if it goes bad. On a Honda with over 100k miles, it's just a matter of time before the water pump goes - so I'd say that it's a good idea to change it now, even if it's not showing any signs of failure. You'd just end up paying for the work twice if you don't do it now - assuming that you're planning on keeping the car for a while. I'm not sure how much a water pump would cost for your car, but you could look it up on the web - additional labor costs to install it during the timing belt change would be minimal.

Q:I have a toyota supra 83 Mechanic said water pump is leaking into engine causing white smoke. He said that hell have to replace water pump nd all gaskets estimated about 500+$ is this accurate? Also water resevoir mysteriously loses water can it be a symptom?: The water pump may be leaking causing the coolant loss. But it is certainly not leaking into the engine. You may have misunderstood the mechanic's explanation of the problem. Where is the white smoke coming from? The engine compartment? Then the water pump may actually be leaking coolant into the engine compartment and onto the exhaust manifold. If the white smoke is coming out the exhaust, it's not your water pump. Car repairs are more expensive today because they are more complex and shops prey on the lack of knowledge that car owner's have about their cars. You wil be charged for the VALUE of the repair, not the actual COST (plus a reasonable profit) of repair. You'll pay about 2x-3x the retail price of the water pump than you would have paid if you bought the water pump yourself. Without that water pump, your car is junk. My daughter paid $700+ to have a $149 alternator replaced.

Q:I replaced the water pump on my 2001 dodge dakota and I still have a leak coming from somewhere. I don't know if i put the bolts in the wrong holes or what. Some bolts were long and some were short. Is there a diagram that shows where which bolts go where?: Dodge man and dave are correct as far as finding the bolt locations and sealing the threads. I have same eng in my 2000 dakota. I did the same as you. I chased a leak for months, Like you I replaced the water pump. That did not fix it. I was told by several people that the intake gaskets have been known to leak. So I kept adding coolant until I had the time to tear it down. The water pump can be replaced with out removing the bracket that holds ac compresser, but the little bypass hose, that connects to the top of the water pump, you have to carefully remove that bracket. Once you do that. you can easily replace the bypass hose, make sure to clean hose nipples good. While that bracket is off, you can easily see evidence of any other possible leaks. Anyway, It only took a few hours to complete this job, in the back yard with a few hand tools. That's been about 9 months ago, and haven't had any problems since. and the little bypass hose was like around $7 at O' reily. Anyways good luck and hope this answer helps.

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.
