Features of D Series Horizontal Multistage Pump
1. This series pump is a horizontal, single suction, multi stage centrifugal pump section, the suction is in horizontal direction, and outlet is vertical upward. Water suction, middle, discharge section, bearing housing and pump body are bolted into one strain, and select stages according to the pump head. 
2. Rotor includes shaft, impeller, shaft sleeve, balance disk, and other parts. Axis parts are connected through the flat keys and the shaft nuts. The rotor is supported by the rotor bearings or sliding bearings in both ends, the bearing does not bear axial force, axial force is balanced by the balance disc. Bearings lubricated with grease, sliding bearings lubricated with light oil, and oil ring lubrication, and cooled by circulating water. 
3. Shaft seal in the form of two kinds, mechanical seals and packing seal. When use packing seal, the packing ring should be placed at the right location, the tightness of packing must be appropriate to the liquid oozing drop by drop. Various sealing elements is in a sealed chamber, the chamber must be filled with some water, as water seal, water cooled or water lubrication. At the seal there is replacable sleeve, to protect the shaft. 
4. From the motor direction, the pump is clockwise rotation.

Q:I need instructions on taking the old one out and replacing it with a new one. Photos will be helpful
Water Pump RemovalRemoval: Disconnect battery ground cable and drain coolant from engine. Loosen water pump idler pulley bolt and remove belt from water pump pulley. Remove water pump inlet tube. Remove three water pump retaining bolts and water pump, Fig. 16. Installation: Clean both gasket mating surfaces on water pump and cylinder block. Install three water pump retaining bolts and tighten to 20-30 N-m (15-22 ft-lbs). Connect water pump inlet tube on water pump. Install water pump belt on pulley and adjust tension to specification. Connect battery ground cable. Replace engine coolant. Operate engine until normal operating temperature is reached. Check for leaks and recheck coolant level. Couldn't get the picure but this should help, the pump is located on the backside of the engine, just be carefull, this engine is really easy to get the pulley on backwards then the belt won't line up right.
Q:I have a slight idea but I would like to see what steps other people have taken. I have a 1992 ford escort that needs a new water pump, what steps have you taken to replace it?
It shouldn't in all probability take that long for a water pump. till they are changing the cam belt on the comparable time which could be greater like it. despite the fact that if ?40 an hour is slightly on the steep component. Get a cost from yet another storage or 2 for the comparable interest and see in case you will discover everywhere greater much less high priced
Q:what is NPSH for the water pump. Can you anyone explain in details? How can it calculate?
Net Positive Suction Head Equation
Q:i have changed water pump,radiator and thermotast and it still overheat
(In addition to the above suggestions) Are the hoses good? Old hoses can collapse, blocking water flow. They should have been changed with the radiator, but not everyone does. Has the radiator fan been checked out to be sure it's working properly? If the fan isn't working properly, enough air might not get through to cool it down properly. Is it actually boiling over, or is the temp gage just showing it hot? I ask because it could be a faulty temp sensor. I'll assume that there's no debris between the radiator and condenser since the radiator has been changed out already. This should also mean that nothing is in front of the condenser blocking airflow.
Q:My water pump keeps getting quite hot after each use. Everything seems to be working properly, except I think that the heat may cause it to burn out and that would cause a huge problem. My pump pulls water from a ground level water tank and pushes water up three flats to the part of my house used for living quarters. The pressure setting is set to cut out at 40psi and cut in at 25psi. What can I do myself before calling in expensive experts?
You have an air volume problem and the tank is water logged. When this happens the pump motor short cycles and creates more heat than it can dissipate. A device inside the motor windings cuts the power until it cools again. You can cut the power off,drain the tank, then start all over, it will give you1/3 air pressure volume over 2/3 water. They have an air volume control that may not be operating properly. I use an air compressor on my pump and pump air into the tank about once every two months. It all depends on how much the pump runs.
Q:I just had my water pump/timing belt replaced and oil change. When the pump failed, white smoke was coming out, which I figured out to be coolant from the smell. Now there is smoke coming out from under the engine, which I believe to smell like oil. Also, the temperature gauge goes up to the halfway point when I am at a stoplight or idling. The highest I have ever seen it is at 1/3.I had my car serviced by the dealership and I asked them. The man said its burning oil residue from the oil change and that it will burn away in a few days. Is this true? I have had my car worked on and oil changed for the past year at this dealership and have never had any smoke or other problems. What else could be going on? Worse case scenarios. Thanks everyone.
Looks like you should have went ahead and bought the Volkswagen now don't it?
Q:the water pump from the factory has an extra hole coming out the side its the smaller one on the end of this pic.
I would be a little hesitant on using an automotive water pump on a boat. The may seem similar however there are several key differences in the way they are made. excerpt from the below URL: In regard to the cooling systems, one of the major differences is found in the water-circulating pump. This is especially noticeable when you have a raw water cooled engine. Unlike their automotive counterpart, a marine pump works in an open cooling system. This type of system is extremely corrosive to the pump. Therefore, the pump must be altered for longevity. A marine pump has a special ceramic seal, stainless steel backing plate, and a bronze impeller to resist corrosion. An automotive style pump, with its stamped steel impeller, would fail due to corrosion in a short time. I have done this before, I boat in fresh water and my boat was raw water cooled, the pump was leaking after 2 seasons, wasn't worth the savings. The extra hole may have been for an optional closed loop cooling system on the boat or like was stated a heater or bypass line in a car.
Q:Fire pump room is required to set up water pump control room?
You can't set it up.If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control.Fire pump for fire as the name implies, pump, fire pump is the introduction of foreign products, according to different classification, divided into different types to its sealed, no leaks, corrosion-resistant characteristics, widely used in environmental protection, water treatment, fire departments for pumping all kinds of liquid, no leakage, no pollution is to create civilization workshop civilization, the ideal pump factory and pump type fire control system are similar, only the head and the flow are different. The selection of fire pump should be based on the technological process, water supply and drainage requirements, from five aspects to consider. Fire pump performance and technical conditions meet the requirements of the Atlantic pump standard "fire pump performance and test method" standard.
Q:I am trying to change my daughters 2004 Grande Am water pump because people tell me it is squealing. We purchased a replacement pump and blue gasket glue. I know to remove the Serpentine belt (not sure which pulley to reduce tension on) then I need to know which bolts to un-tighten, won't the pump turn as a use the wrench? Is there a good video available on changing out the water pump? I've done maybe 5 water pumps in my lifetime all on V-8s with rear wheel drive, so they had easy access. Does anyone know the steps of removal or can someone point to a video of removal replacement?
better make sure it,s not the belt squealing and not the pump. usually when a water pump goes out they will leak. i would be checking the belt first.
Q:I need to replace a water pump
Just take off the fan belt, unbolt the water pump and fit the new one. Make sure the gasket area is clean and use a new gasket. If it has the fan on it, take that off first.
