Type description
Take 350QZB-50 as an example
350: the nominal diameter of the pump
Q: submersible
Z: axial flow
B: semi-adjustable blade
50: 1/10 of the pump specific speed (take the integer part)
According to different pump specific speeds, the flow capacity range of this type of axial flow pump can reach up to 700m3-1400 m3
The principle of Axial flow pump is to lifting water according to the thrust caused by the impeller when rotating. Because water moves along the axial in the impeller, so we called it axial flow pump.
In accordance with its mode of installation, axial flow pump can be distinguished into three class: vertical, horizontal, inclined. Their structures are almost the same. Now the vertical form is used widely. The main accessories contains bell-mouthed pipe, impeller, guide blade, outlet syphon, shaft and bearing, stuffing box, etc.
Summarize of QZ series Axial flow pump:
Installation of water flow Channel: in terms of recommended sample installation diagram
The form of water exit: flap valve or other ways
Installation ways: suspended by bent pipe; suspended in well casing, etc.

Shaft seal
There are two or three stages of mechanical seal. The first stage called carborundum (directly contact with water). The second and third stage called graphite and carborundum.
Leak proof Equipment
QZ, QH series pump have been equipped with leak proof sensors. When the oil tank, the inner part of motor or the junction box has been leaked by water, the sensor will signal or made the motor shut down, and retain the malfunction signal.
Over heating protection system
A overheating protection device is fastened on the motor winding. When the temperature exceeds the stated ＆#118alue, the device will signal or made the motor shut down.
Rotation direction:
Seen from the top of the motor, the impeller is rotating clock wisely.
Application
QZ series axial flow pump, QH series mixed-flow pump is widely used in industry and agriculture water lifting, urban water supply, light polluted water discharge and other water transfer project.
Working condition
Clean water with the temperature no more than 50 or some liquids that are similar to water.
- Q: I do pump sales ~ only to enter the line soon ~ often asked how many levels of motor? I can't recognize myself! So ask for advice here
- With 3000 of the rated speed divided by motor, motor poles after rounding.The number of poles is two times the number of poles.
- Q: So my daughter's car is an 02 Accord manual with about 127k miles. It's making a squeaky noise which apparently is the belts. The dealer says they're too tight, but are in okay condition. They want to change the water pump and adjust the belts for $750. This seems a bit steep to me. Does the water pump need to be changed if it's working properly? How much should it cost to adjust the belts? I'm thinking she should find a more reasonable shop. What are your thoughts?
- Belts can and do squeal. Usually because they are loose and have begun to glaze up. They get a real slick look on the sides. In addition there are several pully bearings that can and do make noise. My suggestion is to find a reputable shop (or two) for another opinion. While you are there, ask what the factory recommended time intervals are for timing belts and water pump on that make and model. At 127k I have to wonder if the timing belt/water pump have already been changed. My last 3 vehicles called for the belt to be changed 80-90k and the pump 100k (if i remember correctly). And as it requires removing all the same parts (on a transverse mounted front wheel drive car like yours) to gain access to either one, shops often recommend doing both to save labor in the near future. As a rule Dealer repair shops charge more, a lot more. Granted they only use factory parts, no used or rebuilt as a rule. The pump is as little as $30 (aftermarket) or more than $200 depending on make and model. If it is located where I think it is you can count on at least 4 and probably 6 hours of labor. However, if like my 2000 Mercury Sable the pump is on the drivers side, in plain view it would only take 1.5-2 hours to replace.
- Q: We usually wait 4 - 5 minutes for hot water in our master bath. I've been looking into ricirculation pump systems. This would have to be a retro-fit system since some of the lines run through concrete slab making adding a return loop on the line non-feasible. I have found some people comment on simply using a by-pass valve system without a pump (ie. Hot Water Lobster). We do have hard water which I've also read that can present a problem with pumps dieing quite quickly. While I'd like it, I don't need 1 second hot water, but I can't stand wasting gallons waiting for 4-5 minutes. A reasonable 15-30 second wait would be a huge improvement. Has anyone had reasonable success with the bypass valve without the pump or should I plan on getting the pump too? Thanks in advance!
- get a under the counter water heater. it will fit under your vanity if you have one and give you several gallons of hot water until the other water line brings in hot water.
- Q: First the shop put in a heater core, but it was still leaking and overheating. Next they put in a water pump. Went to get it and now it wines really loud and the engine use to purr like a kitten, couldn't even tell it was running, now the engine shakes the whole car and it died one the way home but started again. The shop said the cam positioning needs reset again and on the way back to the shop it died again. So from leaking anti-freeze to now it vibrates, dies and wines really loud ! Any ideas what they did wrong ?
- Matbe they forgot to replace water pump gasket, timing belt not aligned with timing of engine.
- Q: my friend has a 2008 Buick Lucerne V8 model. She said its over heating, and steaming from under the hood. the engine is also knocking. Could this be a water pump issue or something else?
- What ever it was it has the engine knocking. Its a little too late to wonder now. Sounds like it lost water and then kept running until she ruined the engine.
- Q: s10 blazer with 130k original miles.. is leaking water but not from the water pump... just replaced it and still leaking from the same area... where are the freeze plugs located? where else could it be leaking from? it lools like its coming from harmonic balancer or close by!!
- look at the housing that the water pump bolts to ,it may be busted and there's some of the bolts that go all the way through in to the block if those wasn't coated with sealant it will still leak from the bolts that hold the water pump on,and that will make it appear to be leaking from the front cover,you got two freeze plugs in the front and three down each side,good luck with it,
- Q: The wiper pump is broken. How much will it cost to fix it?
- This can not be repaired, can only be replaced, change a thirty or forty
- Q: how often do i need to change a timing belt and water pump on my car? also, how much should it cost? should i have it done at the dealers or at a small mechanic shop if i chose to? which would be best? what are steps when having timing belt change?
- The timing belt needs to be change according to the manufacturer's maintenance schedule. Lacking that knowledge, 60,000 miles is a safe interval. The water pump does not need to be changed unless if fails. It's not possible to quote a cost on changing either. Some are fairly quick and easy -- SOHC I-4s without the silent shafts can be as little as $150.00 for the timing belt, and about the same for the water pump. A bit less if both are changed at the same time, possibly. A more complex engine such as a DOHC 4 with silent shafts or a DOHC V-6 or V-8mcan be much more expensive -- several hundred $$$ or more because there may be multiple belts and getting the timing right is a chore. A few are downright nasty as the engine needs to be pulled to get enough room to work on them -- early Hyundai Sonatas were that way. Any competent mechanic can do the job, you don't normally need to go a dealer. That said, the dealer is likely to have factory trained staff and may be familiar with shortcuts and have any special tools needed. The exact procedure is specific to the individual engine. You need a service manual to get it right. Cam timing is hyper-critical. Mess that up and at best the engine won't run. At worst, you can destroy the engine if valves hit the pistons.
- Q: I am trying to evaluate my well water pump and water system to see if the pump is cycling on/off too frequently. What is the optimal quot;ontime? What is the optimal quot;offtime? I have heard the term quot;short cyclingquot;, but no times were attached. I have heard that too frequent cycling can cause a problem, but, again, no times were attached. How can one tell when the system is working within the optimal/normal range, so that no harm is being caused to the system? Thanks.
- There is no optimum time. This is dependent on several factors. Assuming you are pumping into a small tank which is pressurized by the inflow of water from the pump (and the pressure also controls the pump) these reasons can be excessive use of water, the air space at the top of your tank has been absorbed into the water over a period of time and the volume of compressed air too small causing the pressure to drop too fast, or you could have leak in your water piping. If there is not enough air space in your tank, the pump will cycle extremely fast. If you don't have a tank, then the above information is incorrect. Good luck.
- Q: I am new to saltwater tank, and i what to add a sump to my tank, but I don't know what to add to it. what water pump? do i add the filter to the sump or does the filter stay in the tank.
- you do no longer use siphons to flow water to the sump, you employ an overflow and pipes. the point of having the overflow in a tank with a sump is that the pass between the two tanks would be even. while the water is pumped returned to the tank and reaches a definite point that water will then pass returned to the sump. If the capability will fail then the pump will end working, so no water would be moved returned into the tank, no water will overflow returned. the priority with 2 pumps would be that no 2 pumps are comparable. One pump is 2 hundred gallons consistent with hour, the different is 199, next one is 195 regardless of being from an identical authentic line and type. So in case you have a 2 hundred and 199 GPH you will finally end up with the two the tank or the sump spilling after some hours.
