Product Overview of ZW Series Self-priming Sewage Pump
ZW series self-priming sewage pump sets have the advantage of self-priming and non-clogging, can be installed without bottom valve like clean water self-priming pump, but also pumping dirty water with large particles, dirt, fibers , abandoned mine sediment impurities, and other works of sewage treatment and waste material, completely reducing labor intensity, and can make mobile type, easy installation, minimal maintenance, stable performance. 

Structure Description of ZW Series Self-priming Sewage Pump
1. ZW series self-priming non-clogging sewage pump, is mainly composed of pump body, impeller, back cover, mechanical seal, bearing, inlet valve, water valves, suction and discharge pipes, etc. 
2. In the pump body has a reservoir chamber, which is connected with the top back-flow hole and bottom circulation hole and pump working chamber, interlinked to form the axial pump back outer recirculation system. When pump stops working, the pump cavity has a certain volume of the liquid reservoir. When the pump starts, under the action of the impeller, the air is rounded up with the liquid through the gas-liquid separator, and the liquid back into the working chamber, while the gas is discharged from the pump, so as to form a certain vacuum in the pump chamber, to achieve self-absorption effect. 

Q: Hello! Can someone please tell me where the water pump is located on this vehicle? Or where I might find the answer to this question?Thanks!
You see the big hose that enters your rad on the top well follow that hose and see were it comes from the engine..and that's the water pump..pretty simple thing to find my friend..good luck
Q: How can I do a pressure test on my 350's water pump. Some one suggested I do it to make sure it needs replacing.
What makes you think the water pump is bad? If it has a bad seal/bushing then it will be leaking coolant out of the bottom eyelet on the water pump itself and you would be losing coolant, if its overheating then that could be air trapped in the system and may just need to be flushed or ran for a little bit to circulate the system. I would check these options first but if you want to pressure test it just start the vehicle and squeeze the upper radiator hose to see if there is pressure on the hose. I hope this helps you my friend.

Q: I had a re-manufactured water pump installed and after 14 months I started smelling my radiator occasionally. Never suspected the pump since my original pump lasted 60,000 miles and was still fine when they replaced it feigning quot;it is customary to replace water pump with timing beltwhen in actuality my Hyundai Elantra just needs the pump checked every 60,000 miles. The re-manufactured water pump was diagnosed leaking for sure after 20 months. Anyway I believe the leaking pump which didn't get discovered for at least 4 to 6 months caused the early demise of my radiator. Does that make sense?Thanks,Mitzi
completely unrelated and it is customary to replace water pump with timing belt BECAUSE the labor require to replace the pump is the exact same as replacing the belt. If the pump was to fail shortly after replacing the belt, you would have to pay for the same labor charge again and a leaking water pump will contaminate a timing belt requiring the belt to also be replaced. Your radiator developed a leak, that has nothing to do with your water pump
Q: my car ran hot a few times, its a 2006 chevy impala LS with about 50k miles.I do alot of driving but never had a problem until now. I took it to get an oil change and they said that I need a new water pump. I really dont know what that means but im afraid to drive my car until i get a new pump. i called around a few auto places and no one has the part. I called the chevy dealer and they said part and labor is $600. any suggestions of other places i can check for the part? can i still drive my car in the mean time? is it safe?are water pumps usually that expensive?

Q: 94 f150,302. my pump is still leaking after doin the job twice. its a new pump, the first time i used the red silicone between pump and plate,both sides of gasket,and the housing on the block. leaked. then did it again with high tack gasket cement and still leaks. i cleaned all metal both times with brake clean before installing. same with thermostat housing,small leak. ive done 100s of pumps over the years,no problems, so please no rude remarks on mechanical ability. what could it be? it leaks up front of the motor above the crossmember where ya cant actually see the leak,its not a freeze plug. bolts are torqued. any ideas ? thanks
Pay an automotive repair shop to do it. Then it is their problem. Even the best technicians need help once in a while. Yes it costs 3x as much, but no more headache for you.
Q: Hi, my mechanic said that I need a new water pump. I have a 1994 Dodge Caravan SE. What is involved with the whole changing of a water pump? He said it would cost about $400 to $500 for the whole job. Is that correct? Were is a good place to go get one? I live in Staten Island New York. Is sears a good place for that job? What is installed when they do this job? Belts or what??? I thank you for your time and any help is greatly appreciated. I will be taking my car in this week and will leave a best answer based on the correct information. Thanks again :-)
does your van have a 3.0,3.3 or 3.8 litre engine? If it is a 3.0 liter engine then the job involves removing the timing belt. Book time is 4.5 hrs. The other two engine is much simpler, only 1.0 hr to replace the water pump. So since most garages charge about $100/hr it will cost you $450 and $100 respectively. Also it would be wise to change the thermostat and flush the system at the same time. That would be an extra 1.4 hrs or $140. Note: the serpentine belt has to be removed to do this job, so if it is worn replace it. There should be no extra labor, just parts cost.
Q: HelloI am building a small budget underground room. On top of a very waterproof and airtight (besides vents) building, and running a dehumidifer inside, I would like to install a pump underneatth the foundation to suck out water from the soil surronding the building but I'm not sure what kind of pump would be best?Also how would b e the best way to set this up?
What you want is called a sump pump. Most have a system built into them that is triggered by rising water. The idea is to have a hole beneath that allows the inevitable water that will collect a place to go, then when a certain amount gets in the hole, the sump pump comes on and pumps it out to wherever you have the hose or pipes ran to. Being underground, good luck keeping the humidity level down. It won't be easy, and much depends on where your natural water table is, and what it is during rains. Someone in your area might know all that, I don't.
