Product Description:

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:Can centrifugal pumps be idle? What's the status of the empty transfers?
It burns and seals when idling. The individual thinks that it can be indirectly reacted according to the pressure change in the pipeline, and the electric contact pressure gauge can be installed on the suction pipe
Q:What brand of water pump to get?
PowerHead? or Sump Pump? I have used hagen aquaclear powerheads on my saltwater tanks for years 24/7 without a problem. I just purchased 3 MaxiJet 1200 powerheads and a wave timer to see haw they do, 6 months now 24/7 and so far so good. The longest lasting Sump Pump that I have ever owned is made by Ehime, I've had it for 14 years now and it's still going in one of my tanks. I better cross my fingers on that one.LOL
Q:how do you pull the lower unit of a nassan 70hp outboard to install a new water pump?
CW pushes water up into the motor housing.
Q:does coolant flow through the water pump?
You will probably need to replace your water pump. It supplies all of the coolant for your entire engine
Q:What is the difference between electrical/mechacal driven water pump?
The belt driven pump is operating all the time the engine is running. This takes some of the HP of the engine and causes wear and tear of the belt and the pump. The electric driven water pump is operated on demand from the water thermostat and only runs when the water temp. rises above the setting and shuts off again on returning to the setting. Saves engine HP and pump wear and tear...It's much more efficient.
Q:water pump impeller shredded?
I have seen this once before, the impeller was so old and corroded that it partially separated from the bearing or shaft on which it spins, and came into contact with the pump housing. No fault of yours, just replace the water pump with a new one.
Q:Play-more tag along camper water pump problem plz help?
Check to see if the water pump has a filter on it. Could look like window screen or similar. Junk in that will fill up with pressure and cut the water off. If the pump stops running after a few seconds of flowing, its probably a filter. Once they get to a certain pressure, water valve opened or closed, they shut off to keep from burning up. If the water tank was left with some water in it, moss may have grown. Should flush it with some clorox and water. Check with a local dealer to see how much.
Q:How much antifreeze would a bad water pump leak?
it can be leaking also from your radiator..you might want to check the cheaper solutions first. replacing a water pump is very expensive

Q:Water vane vacuum pump - what is the principle of operation?
*Correctly said by Mr.Pete. I think you are asking about water ring vacuum pump. Basically it is a liquid ring vacuum pump. *A liquid ring pump is a rotating positive displacement pump. They are typically used as a vacuum pump but can also be used as a gas compressor. The function of a liquid ring pump is similar to a rotary vane pump the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal. They are an inherently low friction design, with the rotor being the only moving part. Sliding friction is limited to the shaft seals. Liquid ring pumps are typically powered by an induction motor. *Single stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 0.047 bar, and two-stage pumps can produce vacuum to 25 torr (mmHgA), assuming air is being pumped and the ring-liquid is water at 15°C (60F) or less. Dry air and 15°C sealant water temperature is the standard performance basis which most manufacturers use for their performance curves. *You have to take negative pressure if you are talking about pressure. Negative gauge pressure, a way of expressing pressure measurements below atmospheric pressure.
