1)  Product outline
WQ series submersible sewage pump absorbs the advantages with the same products made abroad and at home, holds a comprehensive optimized design on its hydraulic model, mechanical structure,sealing, cooling, protection, control etc. points, features a good performance in discharging solids and in the prevention of fiber wrapping, high efficiency and energy-saving, strong reliability and, equipped with a specially developed electric control cabinet, not only the auto-control can be realized but also the motor can be made sure to work safely and reliably.Available with various types of installation to simplify the pump station and save the investment.
WQ series submersible sewage pump is mainly used for the municipal works, buildings, industrial sewage and sewage treatment to discharge the sewage, waste water and rainwater containing solids and long fibers.
2)  Characteristic and advantage
1. Most of the impellers with the pump of an aperture below 400 come as a bi-runner impeller and few of them is a multi-blade centrifugal impeller. While most of the impellers with the pump of an aperture 400 and above come as a mixed flow impeller and few of them is a bi-runner impeller. The spacious pump casing runner lets the solids easily passing and the fibers uneasily wrapping so that it is most suitable for discharging sewage and dirt.
2. Two independent single end-face mechanical seals are in-series mounted, with the installation mode as the internal installation mode, and, compared with the external installation mode, the medium is more uneasy to leak and also its sealing friction pair are easier lubricated by the oil in the oil chamber. A special spiral slot or a small seam is used to resist the solid
grains to be deposited on the mechanical seal by the pump to make sure of its stable work. The unique mechanical seal layout mode and bearing combination makes the suspension arm of the shaft short, a heavy rigidity and a small jump, more benefit for reducing the leak from the mechanical seal and extending the life of it.
3. The motor of a protective grade IPX8 works in submerged mode and holds the best cooling effect. The grade F insulation makes the winding bearable to a higher temperature and, compared with common motors, more durable.
4. The perfect combination of the special electric control cabinet, the liquid level floating-ball switch and the protective components carries out the automatic monitor and alarm for
water leak and winding overheat, the protections at shortcircuit, overload, lack-of-phase and voltage-lost cut-off, the accurately auto-controls of start, stop, alternation and minimum
submerged depth of the pump, without need of special persons for looking-after, option at will is available between the selfcoupled reducing start and electronic soft start. All of these
makes sure of safe and reliable use of the pump without any worry.
5. Both motor and hydraulic parts are directly linked together, without need of turning the shaft for centering, easily disassembled and assembled to save the time, benefit for the
site maintenance, reducing the stopped time, saving the cost of repair; simple and compact structure leaves a small volume, only simple lifting equipment is needed, as a special lifting
handler is set on the pump; less land area and the pump can be placed directly in the sewage pond, without need of a special pump house, and the therefore the construction investment
can be saved by over 40.
6. Available with five installation modes for you to choose: auto-coupled, movable hard-pipe, movable soft-pipe, fixed wet type and fixed dry type installation modes.The auto-coupled installation means the connection between the pump and the water-out pipeline is made with the water outlet pipe seat of the auto-coupling, without use of the common fasteners, and, when to separate the pump from the water outlet pipe seat, just place it down along with the guide rod and then lift it, simply enough to get free from worry and trouble and save time.
The submersible sewage pump in the fixed dry type installation not only can replace the old vertical sewage pump but also does not fear of flood submersion, so there is no need of a separate flood-proof facility, benefit for lowering the cost of construction.

Q:I recently bought a 1992 Honda Accord. It has high mileage but the records kept on it were impecable up to about the last 3 years. I have read that you need to replace the timing belt/water pump every 80k miles. However; I do not know when it was changed last. The Only record in the book on the subject was back at 90k miles. That was the first time they had the timing belt changed.So How do I know its time to change it again? The car now has 199k miles. I do not want to do unnecessary work before time, however; I also know that the affects it will have on the engine is great if its not done within the right TIME! Is there anyway to know it needs to be done? What kind of signs will the car give? And how much is it going to cost me when it has to be done? Thanks!
can't tell you the price, don't know where you live and where you get yoiur work done, call around.. belts need to be replaced when they're worn. look for cracks, frays and listen for squealing. (sometimes the water pump will squeal when it's bad...) otherwise, take the car in to someone you trust and have them look at it..ESTIMATE only..
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.
most likely the pressure switch is stuck/corroded. this is a common problem with on demand type pumps.try tapping on the pressure switch to see if it will work.if the pump is installed properly,the motor should be at the top and the pump and switch will be at the bottom.i consider these pumps disposable. expect to replace it every couple of years.
Q:how does a water pump work?
Water pump works by suction and lifting up the water to a desired level. The mechanism of pump to increase the hydraulic height/level of fluid. Example : The pump will pump and lift water from a 25 feet deep well and carry it up to fill a water tank placed on a 30 feet high structure.
Q:Suppose the liquid temperature range for the water pump is -20 .. 90 °C. However it should be worked under liquid temperature upto 180 °C. For this, what has to to be done?
YOu need to provide sufficient inlet pressure so that cavitation does not occur.
Q:I would like to have a water pump/valve that I can tie into my house water and will run on a timer. Kind of like a sprinkler system but not so expensive an on a much smaller scale. Basically what I am trying to do is set up an auto-watering (from the tap) system for my animals when I am away for a day or two. I know this is more in the lines of a pet category but than again - not really.
Your okorder /... You can get a hose connection adapter for your tap. You could make one yourself with a toilet float valve. Setting up a pump on a timer may cause you a flood or water damage. It's not a good idea to leave such a system unattended for a few days. You might be better off my leaving several water bowls out if it's only a few days. Good luck!
Q:Im changing my water pump and it has a pully that the belt gos on in front of it and the pully has 1 big bolt in the middle of it and like 4 small ones around it and when i try to undo the bolts the pully turns and im not quite the mechanic but i do know that the pully has to come off 1st so how do i take out the bolts without the pully turning???? and yes the belt is off and battery id disconnected and the car is not hot it hasnt ran in days. and it has a 3.4 v6
actually it works better if you leave the belt tight on the pulley, the tension holds the pulley so you can loosen the bolts, and even that big one, I think, you will need a decent pulley puller to get that pulley off, I suggest you buy a new water pump if you can afford it, otherwise you will but putting water pumps on every year or so, as rebuilt are not long lasting, best of luck, be careful around that radiator with the fan.
Q:My husband has a 78 t-bird and it has steam comming out of it. He replaced the water-pump 2 to 2 1/2 yrs ago. The warranty was only for 1 year should it need to be replaced this soon?
You didn't indicate from where the steam is originating. It could be from the radiator, radiator cap, coolant reservoir, cracked manifold, gaskets, hoses, etc, etc, etc, in which case, the water pump may have nothing to do with the problem (of course, a fault pump may CAUSE the problem, but, without more information, it's impossible to give you a specific answer). As far as how long water pumps last, it depends on the manufacture, whether it's new, used, or remanufactured, how much and how hard the vehicle is driven, etc etc etc. Generally speaking, a brand new water pump should last at least 10 years or 100,000 miles. Good luck!
Q:I have a 2000 chevy impala with 85K on it. I have heard/a weird rattle noise from under the hood for some time now. I once asked about it on here and got suggestions regarding front end problems. I had that checked out and the front end is good. I still have the rattle noise along with a high pitched, but not very loud, squeeling noise when I accelerate. I am leaking coolant and it seems to be coming from near one of the belts. Is this a bad water pump? If so how expensive of a fix is it and how involved of a repair is it?
It sounds like a water pump or maybe a loose connection. It is probably time for a water pump if it hasn't been replaced yet. Parts will run under $60 and it probably involves an hour of labor. The Impala is a big car, it shouldn't be hard to get to and remove. Taking it to a shop will run under $100-$150 for everything.
Q:My water pump is losing pressure slowly even though no water is being used. Your help is appreciated. Thank you.
If the motor sounds louder than normal. Youll need to check the impeller in the pump. Make sure the shaft seal on the pump is not leaking. You either have a leak, restriction in the system or a bad impeller or failing pump motor.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
