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: I noticed my car was quot;in the redand was about to overheat as i was driving, so at first I thought maybe i needed more coolant. I turned off my car and heard a fan noise under my engine for like a minute then it stopped. I checked the radiator and it was empty (no coolant) so i put water in there to get to the store to buy more coolant. By the time i bought some the water was already gone (this was only like 10 min) so I put the coolant in drove home again i noticed i was overheating, i checked again and all the coolant had leaked out too..it was all gone, that QUICK! So i asked a couple of men about it, and they say it sounds like it could be a hose or either a water pump. I don't know which it is, i can't drive it anywhere b/c it keeps overheating and i don't want to get it towed for $75 just to get a new hose. So is there a way i could tell what the problem is? Thanks!
We can't actually tell weather it's the water-pump, radiator, heater hoses, radiator hoses, heater core or clamps without a close inspection. If you're not use to laying on your back under your car held up by jack-stands, hire a private mechanic to do it for you. He will have a simple test instrument to pull off a *cooling system pressure test. A leak source will be apparent in seconds. It's a very inexpensive test also. Get her done before you burn up the motor.
Q: So I purchased this car last week. It ran great for three days until it started leaking water so much that it caused it to over heat. My uncle checked it out for me and said it was either the seal or the water pump. Yesterday we replaced the seal and still leaking water. So we now know it is the water pump. My uncle and every mechanic I know has turned down the job saying it is too much work. I even called two small shops yesterday and got turned down saying it was too much work. It is Sunday so most mechanics are closed. Can anyone give me an estimate on how much this will cost. The problem is everyone is saying that the pump is located inside the timing belt which is hard to put back after replacing the pump. Anyone ever have this repair done before or know a price range. I am a college student and need this car running asap and only got about $500 i can put into it. It is a V6 engine.Thanks

Q: What is the difference between a High Flow Water Pump, Heavy Duty Water Pump or and Electrical Water Pump for a street rod? I have a 77 Camaro with around 410hp with the factory A/C. The Camaro is stock as body, frame and interior. I want to enjoy the car vs racing it. I would like to go on trips to visit family out of town which is around 300 miles and be able to drive the car with out having over heating problems.
The high flow just moves more water per revolution the a factory pump. Heavy duty could be the same as the hi-flow, while the electric pump does not use the fan belt to turn the pump, it's got a small electric motor to do that. See if there's any difference between hi-flow heavy duty, get one of those.
Q: Hello,Thanks for looking into my question. I am a little confused on the definition of a submersible water pump. I am assuming that they are actually submerged but that sounds a bit unlikely in my mind. I suppose if it has a GFCI setup built in with everything sealed beyond the portion that pumps, it would work submerged without any risks involved.Are submersible water pumps meant to be fully submerged? I am mainly interested in this information because I am concerned about the amount of noise they make, being submerged seems likely that they would not be able to be heard. Thanks.
This type of pump is designed to run under water and when submerged will make little noise.
Q: Is it normal for my sump pump hole to be empty. No water in there.. ??
I wish my hubby were home to answer- but I think it HAS to remain in the water. It will burn the pump up if it is dry. A sump pump is meant to be submersed... all the time. You may need a new pump now anyway. You might be burning it up. hope that helps!
Q: I have a 1997 mercedes 320e and it is leaking very bad. I need a temporary fix for the water pump, so that I can take it to the repair shop that is 10 min. away.
fill the radiator and reservoir tank completely and leave the cap loose on the first click so the system doesn't build pressure drive to shop when least amount of traffic and weather is cooler
Q: Please specify the reason, the more detailed the better, the head is the pump 1N fluid on the work done, when the flow rate increases, the shaft power increases, but it does not necessarily have to do with the head of the relationship
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q: I have a cabin cruiser and I recently took it out of storage and had it de winterized. Now everything seems to work except for the fresh water pump for the sink, shower and toilet. Does this type of pump need to be primed? If so how do you prime it? Thank you for the help.
Try hooking a solid 12 volts directly to the pump to 'jump start' the pump.. That got mine started... As mentioned in another post, these pumps are disposable items.. Good luck...
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

Q: I have replaced my water heater and water pump because the owner before me didnt drain it over the winter... but know the water suputers when the pump is on.. when I hook up to city water it works great.. I have not been able to find any leaks.. any ideas???
A lot of the pumps for RVs do cause a slight sputter, Try compleatly filling the water tank, then turning the pump on,. Allow a few minutes to build up pressure and fill the hot water tank, If the sputtering slows, or compleatly stops, your ok. You have to remember that a lot of after market pumps don't work quite as well as an OEM pump. If it's a real bad sputtering, You might need to return the pump.
