Construction of Horizontal Multi Stage Centrifugal Pump (D)
Type D\DY\DF\DM pumps are horizontally installation. The direction of inlet and outlet of Type DY\DF is vertical upward except type D pump with horizontal inlet. Type DYI\II\IIIDF can be also with horizontal inlet and outlet.
The axial thrust gets balanced with the help of balance disk. Type D, DY, DF3_40 pumps get the balanced with the help of
Symmetrically construction
The shaft seal usually uses packing seal, according to customers' requirements, mechanical seal is used, too. Type DF85_67pumps use sliding bearings which get lubricated with dilute--oil.
The others use rolling bearings which get lubricated with grease except type DF85-67 pump with dilute oil.
Materials of tolerance parts: Type D pump are made of cast iron, the shaft is 45# steel.
Type DY: The materials are divided into three types: I - cast iron(the temperature in operation is 20--150degrees)
II_cast steel (the temperature in operation is 45--400degrees)
III_stainless steel (the temperature in operation is 45--400degrees)
Type DF: According to the liquid can be divided into cast steel and stainless steel.
Type DM: Anti-friction cast iron
- Q:I think my water pump has crapped out on my 1997 Jeep Cherokee. I have been leaking coolant for a few days now and there is a puddle under my Jeep after I turn it off and my reserve tank keeps emptying out on me. I replaced the lower radiator hose and still the same problem. It is not over heating so I am wondering if it IS a water pump problem? If it is, could I do the work myself?
- Special tools? What? They are real easy to do. You need only a 1/2 wrench, 5/8 socket, 9/16 socket, 8mm and 15mm. Remove belt (15mm to loosen tensioner pulley, then to loosen adjuster). Remove electric cooling fan (2 8mm bolts at top). Use 1/2 wrench to remove 4 nuts on viscous fan and remove fan. Remove water pump pulley (4 1/2 bolts). Remove hoses from water pump. Remove 2 5/8 bolts that secure water pump to P/S bracket. Remove 4 remaining 9/16 bolts holding water pump to block. Remove water pump. Installation is reverse. No special tools required. I've done hundreds of them and can do one in about 1.5 hours.
- Q:I just put a thermostat in my 92 chevy but the gauge still shows close to hot but go down to normal pretty fast and occasionally i her a loud sound coming from the area where the belt is but i can't pinpoint it. I replaced the pump about three years ago, could that be it again so soon?
- Agree with motorhead. You (question asker) replaced the pump, did you see anything that could break? Only issue with GM water pumps is normally if the cooling system is abused and fluid never changed, which can lead to the impellers rotting away. If the water pump fails fails (not just a leaking seal, the normal failure mode) the engine will overheat. The waterpump is the only thing that moves coolant, if the coolant can't move, the engine will fail from overheating. Take the belt off and see what happens for yourself. Did you purge the cooling system if needed? Did you use a genuine AC Delco thermostat instead of whatever the parts store handed you (probably Stant)?
- Q:How can I test to be sure my water pump is working before I go to the lake and burn up my motor. `72 65hp johnson. thank you.
- You have essentially two correct answers, but looking at the year of your engine I would like to add some clarity. If memory serves, the 1972 engine doesn't have what we today think of as a tell-tale. Meaning that nice little stream of water that comes out of a tube on the starboard side of the engine. Using my poor memory I believe there is and exhaust port, usually one or two outlets together, centered in the rear of the engine, just below the fiberglass engine cover, maybe a little lower. And again, if memory serves, water doesn't flow in a stream from there, but kinda comes bubbling/spraying out. This will be the place to check for exhaust water, and whether or not the impeller is working. Also, like the idea of using the earmuffs, just in case there is thru-hub exhaust you can see it also. If the hub is in the water you can see it exhaust water.
- Q:I would like to know that a water pump or water motor which is of 1 hp what is the height from which it can pull water ? And also if there is a bubbling sound of air and no water is being supplied what does it mean ?
- You say that your pump used to operate properly before, so if the pump is in good condition, the lift mustn't be too great so we can rule that out. It appears to me that the gurgling sound would be made by sucking air, and for this to happen, it would be a problem on the inlet side of the pump. If the person who repaired the pump knows what he is doing, it shouldn't be the pump, so we can rule that out. That leaves the pipe and any fittings between the pump and the foot valve that should be on the end of the pipe. Try running the pump, and pouring water over all joints and fittings, one at a time, if the pump is working properly, a slurping sound will be heard at the leak. The pump will have a priming point, a screw in plug, somewhere on top of it. With the pump stopped, remove the plug, and pour water into the hole. You should be able to fill the pump right up, and the water remain at that level, without draining away. If it wont retain the water, the valve on the bottom of the pipe is either worn out or has something like a stone or gravel preventing it from operating properly. As you have disconnected this pump for repairs, it would have needed priming anyway, which is the filling up with water. It's too much to ask a dry pump to lift water any height, so maybe you don't have a problem at all. Good luck
- Q:can't get the pulleys to line up I know I have a mid 70's 400 and the water pump is later than 1969 but I can't find a pulley that works every one is about a half inch off I bought a aftermarket set of underdrive pulley's from march performance and still the same problem the water pump is a half inch off there was no long or short water pump right they are all the same lenght right??? The only difference I know of is that pre 1968 the pumps have a 8 bolt design and after they have a 11 bolt design is that right???
- Actually there was two main pumps for the older ones,, one was called a short shaft,,and one was called a long shaft,,the long shaft was the most popular,and it all depends on whether your car had power steering,,and air conditioning on it,,all the ones that used the long shaft usually had air,,and power steering on them also,,also some of them had a smog pump on them,,this was the main reason they used the long shaft,,most of the smog pumps got taken off and discarded down through the years,,but you still had to use the pump that had the long shaft,,this is the problem your having,,i own a repair shop in Tennessee,,and have been redoing some old cars in the past few years i to have run across the same problem you are having,,you can have a long shaft ordered for you ,,and it will work fine,,i had to use the long shaft on the one i was redoing hope this helps some.
- Q:I have a 1990 GMC K1500 Sierra and about 1 week ago I went to check the anti-freeze level. I noticed it was a tiny bit down. So I look down at the lower radiator hose and it had a slow drip. So the next day I changed the anti-freeze, New thermostat, and a New lower radiator hose. So I thought it was fine but yesterday I went to go check the anti-freeze and the level was down. I look at the lower radiator hose and it has a slow drip again. The hose I replace was Brand New. Could this be a water pump? I did notice a tiny bit of anti-freeze on the water pump. Or what could this be or do I have to change the hose again?
- here,s what to do. when it,s dripping look under the car and see if it,s running down the hose. it could be coming from the top of the hose like maybe the top clamp is,nt tight enough or it could be coming from the water pump. if it turns out to be the hose then do like i do. i put some ( indian head shellac ) around the inside of the hoses then i put it on. that will stop it from leaking if it,s the hose.
- Q:how do u know when u need to replace ur water pump or how do u know when its not working??? thanks
- The engine will overheat if it's not working at all.
- Q:water flow at faucet only when pump is running, but flow is slow
- Most RV water pumps have a pressure switch. They shut off a few seconds after you initially turn them on because they have pressurized the line. Once you open a water valve (faucet/toilet) the pump will start running again. Low flow could be caused by the size of the pump, size of plumbing, or line blockage.
- Q:TDH what units are present in the pump parameters?
- In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
- Q:The pump assembly and the pump are not a thing
- Water pump components: stator, rotor, bearing, shell, sealing system, under their own consideration
