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: Does the water pump and the circulating pump belong to the centrifugal pump?: As long as the flow and head to meet what pump can be, the general centrifugal pump applications are more.

Q: im attaching a motor from another filter onto my homemade filter. but i dont want to have to run a cord all the way from the pond to a powerplug. does anyone know of another way to such water into a filter without using electricity? some kind of siphon?: 1. I had an electrician put a buried cable in the ground coming up to a weatherproof post with outlets and an on-off switch. It was not as expensive as I thought it would be. 2. You can put the water pump and filters by the house or even inside and run buried water pipes out to the pond, or just put the pump inside and have the filter by the pond which would run by water pressure or gravity. 3. A windmill or solar panel. A siphon uses potential energy stored in the water to work. Once the water has dropped through the siphon, there is no more energy to draw from and the siphon stops. A windmill or solar panel could provide the power to lift the water back up and make the process continuous, or at least while it's windy or sunny. However when pricing these two options even though they would be very cool if you have the large yard to accommodate them, they turn out to cost much more than either 1. or 2. and have much higher maintenance costs associated with them. 4. If it's a very small pond, you can get a solar powered filter/fountain that looks like a floating plastic lily pad. My son had one of these, but it only worked on the sunniest of days, and lasted one summer before wearing out. If you add a large block of filter foam over the intake it may last a little longer. Rinse it out two or three times a week.

Q: i took off the lower unit to fix the gears. im not sure ill be able to put it back on with out knowing how things work in there.so how exactly does the water get pumped. and what does it have to do with the gears, because even though the prop wasn't turning, the water was still pumping.thanks.: The driveshaft is always turning. A pinion gear at the bottom of the driveshaft spins the forward and reverse gears, which are freewheeling (in opposite directions) on the prop shaft. The clutch dog is splined and/or pinned to the propshaft, and moved forward (to mesh with the forward gear) or aft (to mesh with the reverse gear) by the clutch dog cradle, which is moved by the up or down motion of the shift rod. The backside of the forward reverse gears are machined with square corners that mesh with the clutch dog. So, the engine turns the driveshaft, the driveshaft turns the gears, the gears turn the clutchdog, and the dog turns the propshaft. Meanwhile, as mentioned, the drive shaft, which is always spinning, is also the water pump shaft. The water pump has a neoprene impeller in a chromed housing; a very tight fit -- the vanes have to be bent over to fit. The center of the housing is offset from the shaft, so the compartments where water is drawn in get smaller as they rotate toward the discharge, which provides enough water pressure to force water through the engine even at idle speed. The impeller is fit so tightly into the housing, that it will generate enough heat to melt and break up without a source of water -- it only takes about 30 seconds of dry running to seriously damage the impeller. to fix the gears, you have to use a gear puller to pull the propshaft bearing carrier. The reverse gear will fall out. Reach in with a long box-end wrench to remove the pinion gear from the driveshaft, and pull the driveshaft bearing housing out with the driveshaft. When you remove the shift rod, the prop shaft, forward gear, clutch dog etc should be accessible. There's a lot of complicated steps to accomplish each of the above, and some critical measurements with near-zero tolerance. Don't do it without a factory service manual in hand.

Q: Domestic pump automatic shut off the water, but also turn around, stop what happened?: You can find a water pump factory people ask, ah, Baidu, find a corporate website, many have online advice. By the way, a site called water industry navigation, pump manufacturers included a lot, and find it may be faster.

Q: does any one know where the water pump is located on a 97 nissan altima? and where can i find one, would pep boys have one?: most cars, it is in the front, driven by the timing belt. If you are going to replace the pump, replace the timing belt also (if there is one), as it's probably overdue, and you have to remove it to get at the water pump. Also the tensioner. Replacing the timing belt is a difficult task. If you screw it up, you could damage the engine. .

Q: I have a 1997 Pontiac Grand Prix 3.8 v6 engine. My car has been overheating lately and my low coolant light came on so i put antifreeze in it and the light went off. I drove about 3 blocks and the low coolant light came back on again and the thermostat was at the hot mark so i checked the antifreeze and it was just about empty. I did noticed when I was pouring the antifreeze that some did run out the bottom of the car but it wasn't alot. Also I noticed that in the morning when I get up and drive my car the thermostat could be at cold but if I drive about 3 blocks it's almost at the hot mark. Please help me determine whats wrong with my car. Is my water pump bad?: if your water pump is bad you will see coolant dripping from around it. Sounds to me like you have a MAJOR leak or a blown head gasket. If the engine oil looks like chocolate milkshake after you drive it, then its the head gasket. Fill your radiator up with water and drive till the engine temp is topped out. then get out and open the hood and look for spewing water. If you see it then there is your problem... if not then check your oil for milkshake.

Q: A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 for pi . Round your answer to three significant digits.)The tank is a spherical shape has a radius r= 6m and a spout height of h=2m.I really dont know how to start this problem correctly. Any help will be appreciated. Thanks!: The pump will not have to work until the water drains by gravity to the level of the spout. Then, Work = Weight of water * Height of lift Find the distance, d, of the center of mass for the remaining water in the bottom 2 m of the sphere. The height of lift will then be 2m - d. The hardest part is finding the distance d to the center of mass. I don't remember how to do that.

Q: We still have water, but it keeps constantly running, and won't stop. The pump itself got warm/hot, and we're afraid that it's going to get ruined or blow up or something. We turned it off for about 30 minutes, then back on to bottle up some water. It's the middle of a snowstorm, and a horrible time for a water pump to stop working, help please!! Any suggestions and fixes, please let me know. Thanks!!! :): jane has the correct answer,,, it probably is a broken and leaking pipe somewheres,, it will cause the pump to burn out and may have already melted the contacts together,,, not much to do during a snow storm and after you need to find ,, repair and then insulate the area it leaked from

Q: Hey I need to pump water from a river and use be able to use it through a hose and also make the hose have pressure. I was thinking pump the water into a barrel and into a hose or something from there? Anyone know anything about if this would work? What would I need? thanks: buy a submersible water pump. they are the best and longest runing with high pressure. also they are portable and u can take out any time. they are applicable in sea , rivers, very deep pumping etc. but remember to wrap it with a light and silky cloth to prevent the sand going in to it before use in sea and rivers. u dont need a barrel or tank. As they re not heating,they can work continuously even for a years.u can operate from a distance, much pressure than any centrigugal pump. hope it heps. good luck.........

Q: 94 f150,302 engine. the water pump comes with 2 gaskets. one behind a metal plate on the pump and another for mounting it to the motor. my question is do you have to use sealant of any kind on both gaskets or can you just bolt it on?: Weekend before last, I did the entire timing chain cover and water pump assembly of my '92's Mustang's 5.0L. Used the red silicone.......doesn't leak a drop.
