Product Description:

1. Product Introduction

WQ series submersible sewage pump is mainly used for municipal work, industrial building, hotels, hospitals, civil air defense, mines, etc. It can be widely used in transfer waste water, rainwater and living water etc. which contains solid grains and various long fibers CNBM WQ series sewage submersible pump have many advantages, such as, hi-efficiency, circumvolution proof, blockage free, auto-coupling, hi-reliability and auto-control, etc.

 

2. Technical Performance

Discharge diameter: 50~600 mm

Capacity: 10~8000m³/h

Head: 5~60m

Power: 1.5~315kw

Diameter of pass solids: 20~145mm

 

3. Operation Condition

1). Rated Voltage: 380V(660V), Frequency: 50Hz, 3-phase AC.

2). Temperature of medium under 40ºC.

3). PH value: 4~10.

4). Volume ratio of solid in medium below 2%.

5). Density of medium should be lower than 12000kg/m³.

 

4. Structure Characteristic

WQ series submersible sewage pump is equipped with status indicator and protection device to ensure for pump safe and reliable operating.

1). The unique cable airproof is adopted, avoid leakage of cable.

2).  Heat protector in stator assure of operating life of the motor.

3).  The pump adopts outer recycling cooling design with motor power more than 18.5kw, which can keep the pump operating safely under the lowest water level.

4).  A floating switch is installed at the bottom of motor chamber to protect the mechanical seal in the motor side.

5).  The oil-water probe is installed at the up end of the oil chamber between pump and motor that can protect the mechanical seal in the side. If leakage occurs, the system will signalize and start protection.

6).  Adopt perfect mechanical seal, the sealing material adopt tungsten carbide, silicon carbide and hard metal alloy, which can prevent the water from entering into the motor, and keep the operating reliable and safety.

7).  The auxiliary impeller can balance the pressure outside of the mechanical seal, prevent the water entering into the oil chamber and prolong the life of the motor.

8).  Unique impeller design, wide passage allow large solid and long fiber passing through freely, it features non-clog, convolve-proof and good passing ability.

9).  The changeable wearing ring is installed between the impeller and the volute to keep the optimum operation conditions.

 

5. Impeller Design Characteristics

For the feculence pass freely, it must be widen the flowing passage of impeller, for the big pump, can used for double-vane, or three-vane, for the small pump, it used for single(double) flowing passage, like a bent pipe has same section, it has a good passing characteristic, avoid stop, convolve caused by slowing current possibly. The especially flowing passage of impeller, cooperate with logical volute, made the paper, soft goods, garbage bag and other material in sewage can passing freely and the pump have no vibration in the course of running-in and load through the impeller balance between dynamic and static state.

 

6. FAQ

1). How long is your warranty?

Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications.

Q:how do water supply pumps work?
water pumps have impellers which when rotated mechanically by a motor the water gets pumped up from lower level to a higher level depending upon the speed of rotation.the direction of waterflow is regulated by means of pipe lines which have curved bends to regulate smooth flow of water pumps in different directions. there r many differnt pumps each differs from one another.please vote
Q:Suzuki 1982 DT8 Exhaust in barrel affect water pump?
i agree with richard. get a hose attachment, a set of earmuffs and run it with them. you wont be able to see water exiting the prop shaft area with the motor in a bucket. hte indicator, where the motor normally pisses to show its pumping water, those sometimes get clogged and need cleared out. it is possilbe for the motor to suck air, or exhuast, instead of water, if a gasket is bad around the impeller. in addition to the gaskets normally changed, there are more gaskets underneath that. usually, those gaskets only go bad if the motor is overheated to the point that the old impeller housing shows signs of excessively high temps. if the old housing was half metled, id go ahead and pull it apart and change the other gaskets too. but the exhuast chooses to exit that port becuase its easier to go out there then through the water. and you see water exit with it, so you know it is pumping water up into the motor. i'll also point out this much. if you are unsure, take it to a proffessional. you can total your motor by operating it without a properly working cooling system. paying a pro to fix it right is much cheaper then a new motor.
Q:1996 mitsubishi eclipse water pump?
Ive owned some Mitsubishis... they have an inclination to no longer be the main solid automobiles on earth. I actually have a eagle talon tsi (the swifter yet much less solid kind), and it choose maintenance surprisingly many times. the rs is a little extra solid, yet for my area, in case you do not have funds, and its your first motor vehicle, get something a splash extra solid.... (i'm gonna hate myself for asserting this) look at a Toyota or Honda... i made the blunders of having a ludicrous motor vehicle as my first and that i had no longer something yet problems with it... i had to spend what little funds i had to maintain the piece of crap working, purchase a first rate motor vehicle for now and spend you cash on a date or something :) -do notcontinual swifter then your parent angel can fly-
Q:is sump pump water clean?
yes, I would bet it is in the water. sump pump water is consider by the industry to be GRAY water. you don't want to drink it. if its an emergency, you could boil it, but not in w.v. if you are living there with this type of spill they incurred. even boiling that water will not work. better safe than sorry
Q:How would I temporarily repair my water pump, so that I can drive it to the repair shop?
old mechanic trick get pepper and pour it in there/use a whole box if you have it/works
Q:Acura 1.7 EL Timing Belt and Water Pump replacement?
Never get a dealership to work on your car unless you're not paying for it. Get a good garage to do it for you instead. If you're mechanically inclined you might be able to do it yourself, but im not sure how hard it is since it sounds like your timing belt powers your waterpump (just makes it more difficult, whereas my car has a separate belt that powers my WP). Otherwise you got a honda engine in there it sounds like, so it's not going to be insanely complicated.
Q:do i really need to replace my water pump?
You can do that, but you can't fill it with pure water because in time you'll have only water in the system which can cause problems. Antifreeze also increases boiling point of the water/antifreeze mixture thus protecting the engine... You should always add 50/50 mixture. Anyway, bad pump is generally bad for cooling. It is better to have leaking radiators than bad pump.
Q:Anyone know anything about Mazda water pumps?
If you had a water pump leak you'd know it! There would be coolant draining out of water pump seal the minute you filled the cooling system. A water pump leak doesn't get coolant into the motor. It will get the timing belt wet with antifreeze and cause the belt to jump time and possibly bend your valves. The only way you'll get coolant in the motor oil is if there is a head gasket leak. To check for that you need to have a block test done.
Q:Power of a water pump?
You have the following information: Mass of water delivred = 4*10 = 40 litres = 40kg Height = 4 metres time = 10minutes = 600 seconds Work done = m*g*h Work done = 40*9.8*4 work done = 1568J Poweer = work done / time Power = 1568/600 Power = 2.61 Watts. It seams a very small pump to pump only 4 litres/minute.
Q:hooking two water pumps together?
If you connect two pumps in series and not parallel the pressure will increase but you need to have them connected so if the well stops running the other does also.
