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

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 for WQ pumps

1). Can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

2). Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

3). How long is your warranty?

Q:Water pump maximum flow and standard flow?
Centrifugal pump, flow and head is an inverse relationship between the maximum flow, you said, lift the corresponding conveying pump is relatively low, the standard flow, the rated flow is designed and run in standard flow, pump efficiency is the highest, if more than the standard flow operation possible lead pump overcurrent heating, and a series of cavitation phenomena
Q:Water pump pressure for shower?
Himin newly has launched a solar patented booster pump for non-pressure solar water heater and it's quiet and gives comfortable pressure for shower.This pump fits for area where water pressure is small or rural area.
Q:if water pump is working should lower rad hose to thermostat be hot, it is cool and spongy!?
Your new pump will be tighter then your old pump just makes sense and no you can not pack grease around the bearing, it's sealed you can't even see it. You have given me the best clue you could have and that was that you accelerated and the temp went down. What you did was force more water to circulate in the system. So that leads me to think you have air in the system or the fan is not doing it's job. I'm going with the air in the system but if your car has a viscus fan drive I'd give it a turn, it should not free wheel. Why dose the work head gasket ALWAYS have to come up when someone say overheat? Keep it simple and go back to the last thing done.
Q:Looking for help picking a water pump.?
I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.
Q:change water pump on 1995 z71 5.7?
Disconnect battery ground cable. Drain coolant from radiator. Remove upper fan shroud. Remove drive belt. Remove fan assembly from engine. Lower radiator and heater hose from the water pump. Remove water pump attaching bolts and water pump, Fig. 15 . Reverse procedure to install. Tighten water pump attaching bolts to specifications
Q:Will a water pump work?
Be careful what you buy. Most aquarium pumps are AIR pumps. Why not just use a siphon? As long as the storage tank is higher than the generator it will work. Get a hose or plastic tubing of the size you need, put one end in the tank. Suck on the tubing to start flow. To stop flow just pinch off the pipe or raise the spout above the water level. you might even install a valve if the tubing is large enough.
Q:Pressure of water after pump question?
1.If there is no water at the discharge of the pump then there can be no pressure. 2. If there is water at the discharge of the pump, but the pump is not running, then there will be a pressure in the system. 3. If the pump is running, the pressure in the system will be higher than at 2.) above becuse it takes additional pressure to move the water through the piping. The flowing water requires additional pressure to get thru the piping system.
Q:Anyone know where I can get a water pump?
It's going to be hard to get any DC pump tht can pump 15m (45+ feet). Get and inverter and get a 115v/220v AC pump to do the job. Those are much more plentiful. I know it's more to buy and install, but it is what it is.
Q:Is this noise from my water pump?
wiggle the fan blades and if they move any it is a bad water pump, they will also leak a little bit under the main shaft of the water pump housing, there is a hole on the bottom and top just for this reason, the metal squealing is the impeller in the water pump, it wont last long now I agree....assuming you did put enough coolant back in it after changing the radiator.
Q:how many consequence hours can I leave my water pump working?
Hey Don ..did you mean consecutive hours..if so. Here is how to do it..If there is fluid to be pumped there is sometimes a controller that will ask the pump to stop when it reaches low level . And again ON when it senses high level. Find this device, if one exists and either defeat it mechanically or wire around it electrically.Either is pretty simple. NOW that i have told you how to get it to run all the time. I though I might mention a timer..A timer, in series with your pump, will cut it off and give the liquid level a chance to rise as well. Timers can be defeated the same as all other protective devices,, My question is Are you sure this is what you want to do ? The plug on the end of the cord ,it must be a small pump if only 2 amps, should be your only control .If it has an auto off feature it's there to save your pump from burning the barn down ,so to speak, Why not take another look at your application. if you do have an endless fluid supply ,like a closed loop trickling fountain, remember those evaporate if make up water is not added. Sometimes though you need a pump to run 24-7 in which case just fool the controller..Of course the human is the true controller... :) Well I have armed you with enough info to get by on this please do so safely.
