High pressure Water Pump

1.Introduction:

CDL/CDLF high pressure 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.

2.Applications:

· Urban water supply and pressure boosting

· Industrial circulating system and processing system

· Water supply for boiler, condensing system, high-rise building or fire fighting system.

· Water treatment and RO system

· Cooling water system

3.Electric motor:

· TEFC motor,

· 50HZ or 60HZ 220V or 380V

· Protection class: IP55, Insulation class: F

4. Operation conditions:

Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers

medium temperature: -15°c~+120°c

Capacity range: 1~180 m³^_/h

Head range: 6~305 m

Q: Alright,I happen to be the only man in the house and the plumbing is a bit faulty. You see,the machine has been filled with water as necessary and was ignited. It sounds perfectly fine and you can feel water run through the pipes connected to it, when touched. But it's been an hour now and the taps are not producing water. Please can anyone help? Under normal circumstances,there should be enough water now but the taps are all empty despite the water running through the pipes. What can I do? Please help. I filled it with even more water and there's no result. Help please. Thank you.: If you are in a very cold climate you could have frozen pipes. If not call a plumber.

Q: How large is the starting current for a 1.5 kW submersible pump?: The starting current is 2-7 times the power

Q: how do i take water pump off took all hoses and bolts i think off dont know whats holdin it on how many bolt hold it on i know the seal can hold it on ther but it wont budge even when i use block of wood and tap with hammer: Lt1 Water Pump

Q: I received a call from my daughter who said that the water pump was making a grinding noise. She sent a photo to me showing 0 psi on the gauge. I came home to find it actually working again but after running water straight from the pump I found that it is really rusty. What is this caused from? Our water was nice and clear! We've had freezing conditions here. Still doesn't explain the sudden rust.: it relatively is probably not appropriate. a threat that the sump pump and the nicely pump have been tied jointly and has a GFCI breaker interior the line. See in case you will discover a GFI it relatively is likewise tripped.

Q: can a failing water pump sound like rattling or popcorn until the motor begins to over heat? the sound is nearthe waterpump. it goes away once the temp starts to overheat.the temp will get near redline then go down to normal and then start creeping up again. thanks for any replies.: it sure can.

Q: i was coming home from from work and my jeep thew the serpenteen belt and my water pump is the only pulley not moving good like the rest and is leaking coolent. and people with just dump **** to say dont comment on this: With either engine your jeep cherokee would have a 2.5 or 4.0. Both have the same pump, and the 2.5 would be easier because you would have more space from the smaller engine. But there not hard to replace. A repair manual would be help full if you have never replaced a water pump before.

Q: Hello, i have a 1987 volkswagen cabriolet that i purchased earlier this year. So far its been a pain in the butt. Recently i noticed it overheats real quick, but it didnt use to. then i noticed the coolant/antifreeze was being used up like no other! I discovered, after being parked at work, that it was leaking. it leaks basically anything i put in there now!! it leaks from the water pump housing,.,.... at least thats what the internet said it was.. its leaking from the end of the hose that connects to the engine... (the hose that comes from the coolant reservoir.) What do i do? I dont feel any cracks? does this part crack? is it an o-ring or somehting? how can i fix it? what happens if i dont? I am really absolutely NOTHING ABOUT CARS. Please help!!: The water pump a vent designed in the housing that will drip coolant when the water pump seal is blown. Replace the water pump.

Q: 1997 Chevy Cavalier, 2.2 engine. In the past 2 days I noticed that my temp gauge was reading a little higher than usual but not in the danger range. I checked and nedded to add coolant. Last night it started making a chattering or maybe klunking sound. As far as I could tell it was coming from the water pump but it stopped before I could get out of the car and look to see. Now the coolant is low again. Are these signs of the water pump being bad or could it be something else?: It is possible your water pump is worn out, yes...but it could be other things too. I would change the thermostat first, being a much lower cost. If the thermostat is sticking shut, or not opening right at all, it can prevent the coolant from circulating right. That lets the whole engine heat up and coolant boil. That may be the sound you hear, normally called a water hammer... If you take it to the shop, which you should do now, ask them to check the thermostat and water pump, to be certain of the problem... I hope it is just the thermostat that is causing this, but check it good...

Q: When the pump is running with frequency conversion, the instantaneous power is greater than the power frequency operation, and the actual flow and lift are less than the power frequency. When running, the efficiency is very low. Why?: Pump power frequency operation, speed is rated. Frequency conversion actually adjusts the speed of the pump (the speed becomes smaller), and the flow of the pump moves parallel and downward. As for efficiency, it depends on the operating conditions of the pump. Does it deviate or run to the minimum efficiency position of the flow curve of the pump?.

Q: I have a 2000 chevy impala with 85K on it. I have heard/a weird rattle noise from under the hood for some time now. I once asked about it on here and got suggestions regarding front end problems. I had that checked out and the front end is good. I still have the rattle noise along with a high pitched, but not very loud, squeeling noise when I accelerate. I am leaking coolant and it seems to be coming from near one of the belts. Is this a bad water pump? If so how expensive of a fix is it and how involved of a repair is it?: It sounds like a water pump or maybe a loose connection. It is probably time for a water pump if it hasn't been replaced yet. Parts will run under $60 and it probably involves an hour of labor. The Impala is a big car, it shouldn't be hard to get to and remove. Taking it to a shop will run under $100-$150 for everything.
