1.Introduction

DDL serial is horizontal volute double sction pump. This serial pump is an unique new product which is developed by our company by combining the advantages of the products of many other factory. DLL serial pump adopts inner arranged sealing and lubrication structure. The lubrication, flushing of seal system by closed circulatingwater are more direct, efficient. Linearity designed outline, the casing cove with streng structure make the pump to be on intrgrated mass, flexible stucture design makes pump more nicer. The casing inlet and outlet of DDL pump are both located under the casing. thus the rotor can betaken out without disassambling serial pipeline, so its maitenance is very convenient. Most part of the casing adopt double-passage design to reduce radial force. Casing, casing cover both adopt resin sand board moulding, this ensures a good appearance, accurate passage dimensions and high efficiency. Transmission is driven by motor through flexible coupling. Turn direction:clockwiserotation viewed from drivinged for clockwise rolate, and counter-clockwise viewed from drivinged for counter-clockwise rotate.

2.Applications

3. Operating conditions

Capacity range: 50~36330m³^_/h

Head range: up to 160 m

Q:Our water pump had a leak in one of the pipes which kept making us Los the prime. I've replace the piping so it no longer leaking but I can't get I to work. The pump runs but the water doesn't move-. The pressure says it is at 50 but nothing. Also its a sahllow well pump jut bought last sprig.Any ideas? Sorry for the bad grammar new to this tablet.: You would be wise to call a pump expert and have them examine it.

Q:When I turn on my pump for the pool water-fountain it will run for 30 seconds or 4 minutes or anywhere in between then it just shuts off. I push the remote on button on again and it runs for a few seconds. Sometimes it will run for a while longer but mostly short durations. Thanks in advance for your help.: Contrary to another poster's reply, if it were an electrical problem and there was a larger than acceptable load (draw) on the electrical system, the breaker switch would click off as the amperage from the pump or wiring would create too great a draw. That is what breaker switches are for. It is likely that you have a vacuum leak or something plugging a line. Check the filter basket ... check the pool water return lines from the pool to the pump. Bleed air out of the filter. If those don't work, it would be time to call a pool service.

Q:In case our electric goes out we would like to be able to run the water pump (for the well) via solar panel. Can you give me instructions, pitfalls, recommendations, links etc to help me get started?The more solar info i can get the better!thanks 10 points on offer!Our sunlight is unobstructed: Build okorder /

Q:i have a 97 mercury mountaineer and i recently got the thermostat changed in it. after doing so we noticed that the car was leaking antifreeze. we checked to make sure everything was tight and there was no cracks and my uncle said he thinks its the water pump how can i tell: since the leak only occurred after thermostat change ? it is reasonable to assume it is leaking around the thermostat housing. check this area first . ( did we fit a new gasket ? etc) water pumps have a small hole on underside that will weep ( leak) when seals are worn and pump needs changing. we can check pump is working by observing coolant flow. with a cold engine remove coolant filler cap.start engine and rev a few times to around 3000-35000 rpm observing ( may need an assistant) coolant flow into expansion chamber ( where you removed filler cap from) you should note coolant flowing across or into the expansion tank. if our pump has failed we would over heat !! check engine cooling when driving.

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!!: This Site Might Help You. RE: how to tell if i have a water pump housing leak?

Q:is there a surface water pump that can pump water from a 1000 foot well?: If what you mean with surface water pumps are those pumps mounted on the ground to distinguish them from submersible pumps , yes there are surface pumps that can pump water from a 1000 ft well. These are the so called jet pumps or deep well pumps wherein part of the output water is returned back to the bottom of the well pipe through the space between the outer pipe casing and the inner pipe and passed through a venturi opening to create an upward water jet which will push more water upward.

Q:Hi,My problem is of this automatic water pump ,it is disrupt always I don't no why..I also want to knew what is the function of the pressure air tank??? The picture is here:: WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....

Q:I did change water pump before but not on wv beetle?: For okorder /... Put this in the search box: Volkswagen New Beetle Service Manual: 1998 - 2002. Click then download the pdf file. Good luck!

Q:and it still runs about every 1/2 hr even if you are not using water. I have no leaks from the pump thought the house so I think the problem is between the house and the well. I can't hear or see any leaks in the elbows in the well. I tried to pull the foot valve up but can't get it out. I replaced the pump cause it was worn out and it was running every 15 min. Do I need to set the pressure on the new one it cuts off at 42 and on at 20 psi and what else could cause it to run when it shouldn't? I know I should call a plumber, but haven't worked in months and can not afford one.: Sounds like foot valve to me is not seating properly and you wouldn't hear the leak under water level guess your tank has enough air gap top of tank and water level if that is insufficient pump will also short cycle should have a valve stem with internal bladder inside of tank if it is similar to my old tank. Your pressure is same as my old one and it was fine.

Q:My truck has been over heating, and I cant figure out whats going on...the only thing that gets really hot is the upper radiator hose, and the radiator....I just noticed there was a plug unhooked from the water pump, what does that do? Or maybe it could be the thermostat? It just overheats, and when I park it, it wont start half the time, usually I can let it cool off and go, but sometimes it just dies and I have to let it cool off and jump it off.: Get yourself a Haynes or Chilton repair manual at Autozone, Pep boys, etc. Make sure you clean the old gasket material completely off the block before you mount the new pump. If not, you'll leak and have to do it all over again.
