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: What I am trying to explain is that I took my vehicle to be serviced for a water pump. They installed it, but when I got my vehicle back, it started making this clicking noise. I took it back to be diagnosed and they came back to me saying that I need a new engine? (Before I took in my vehicle there was no clicking sound or problems, just the water pump.)Could this be the dealer trying to pull something for their mistake or what?: It is hard to answer given the information given. What kind of car ? If your car has a waterpump that is turned by the timing belt, yes the shop could have messed up on the cam timing as they re-assembled after installing the pump. What is causing the clicking sound ? It could be a bent belt or any of a hundred things. Where do you hear the sound coming from ?

Q: Okay so earlier, I went to go test out my water pump and all on my 66 mustang 302. And I got it up to normal operating temp, and had the rad cap off. I gave it some gas, the coolant level didn't go down, instead it came out the rad pretty badly. I've been having overheating problems, and I have no leaks, i just replaced the thermostat a few days ago, it didn't help. I haven't seen any leaks around the weep hole on the water pump, or noises. Other than a belt that does need to be tightened a bit, you can hear the belt squeling a tiny bit. So do yall think it could be my water pump?: if at an idle you see coolant flowing in the radiator, the pump is ok... More info is needed here really, assuming you don't ever have to add coolant though... I'd flush the system... if you do add coolant and find no leaks around the engine (weep hole, hoses, freeze plug) check the passenger side floorboard for moisture, the heater core may be shot...

Q: I just bought a house and we have well water. When I went out to change the filter on the pump I noticed a valve leaking...I went to check on it and noticed it had two settings if you will. one says System and the other says by pass if I move the lever to system the leak stops, if I move it back to bypass the leak continues...question is which one should I have it set on and what is the purpose?: Okay, Adam, we also have a well and just put in a new one. The setting that says System means that the water is running through the filter. The setting that says by pass means that the water is NOT running through the filter. You will have water either way in your house (or you should). It is just either, it is running through the filter, or it is not. I hope I have helped. gram

Q: Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?: In the picture, to the right is the entrance, the left is the exit, the water pump inlet channel section area generally will be bigger than the export.

Q: Today I was installing a new water pump on my 1999 grand Prix. When tightening the bolts one of them snapped off. Now the pump leaks from that broken bolt. I was wondering if I would be able to stop the leak using some sort of sealant or would I have to take the car in to get the bolt removed?: You will need to remove the water pump and see how far down the bolt broke. You may be able to get hold of the bolt with vice grips and get it out. Worse case you will have to drill it out and re-cut the thread or use a bolt extraction tool, you simply drill a hole smaller than the bolt and the extraction tool turns the opposite way to the bolt thread and as it gets tight its meant to loosen the bolt in question. I have done this many times and it dose not always work so you may need a professional to do it.

Q: I was wondering if water pumps make any noise when they are submersed? Also, my pond is quite small and I don't want to scare my fish with a noisy pump. Thank you!: majority of the pond pumps you get to day are extreamly quiet and wont bother the fish or you at all

Q: my marine engine doesnt pump water can you tell me some faults can be thanks vic: Depends on what engine and what pump check the impeller to see if it is bad.

Q: 1.5 kW three-phase pump with 600 meters line, should match what big line?: Resistivity of copper conductors is 0.017 ohm mm / m, R= P L/S, the resistance can be obtained by 600 meters 2.5 mm - single stranded conductor is 4.08 ohms, and rated current 1.5KW three-phase pump is about 3A, so the pressure drop resistance of the wire leading to the U=4.08X3=12.24V. So if the supply voltage can be stabilized at 380V~400V, with 2.5 mm - cable; if the supply voltage is between 370~390V, with 4 mm - cable. (above is copper core, aluminum core shall be increased by 1)

Q: i have an underground water tank, my jet pump went out again, got a new one, waiting for the guy to come install it. i got an old fashioned iron hand pump, for when the electric, or the pump goes out again, i can pump out water. got pipes, fittings, foot valve. i just dont know what kind of base to make ,to bolt pump to, over the pipe that will come out of the ground. any ideas?: you can make a wooden floor cover using a treated good lumber of 1 X 6 for the floor and 2 X 6 lumber for the floor joist. assemble the 2X6 lumber for the floor joist. depending on the top area of your water tank. arrange the floor joist at 0.60 meter spacing and 1.2 meter braces. after that, use 1X6 lumber as flooring with at least 2 cm spacing between lumber. as on the base of your pump, you can reinforce it by adding 2X6 braces. use a lug bolt depending on the size of the slot at the base of your pump then bolt it on top of the 1X6 flooring. its better if we can draw it here to make it easier to understand and explain i dont know if this can help much because we havent seen the actual situation of your tank and your pump.

Q: My water pump went out. I had a new water pump put on my accord a year and a month ago. Since then have driven 5-6,000 miles in a small city town. Does this makes sense. Could it be a cheaper water pump was put on my car and it went out. The person who worked on it is a mechanic who does a bunch of cars on the side. Last time he worked on my brakes, I had to bring it back because he put cheap ones on.Can I call this guy back? What could I say?: usually 7-10 years so at 5000 miles take it back
