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?

Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Mgh=ptIn 1 hours30*1000*10*30=p*3600P=2500 (W)Therefore, the ideal state should be more than 2500W motorWith all kinds of losses, it is recommended to configure more than 3000W motors
Q:my rv water pump runs for a short time and then shuts off .?
Most RV water pumps have a pressure switch. They shut off a few seconds after you initially turn them on because they have pressurized the line. Once you open a water valve (faucet/toilet) the pump will start running again. Low flow could be caused by the size of the pump, size of plumbing, or line blockage.
Q:Will a water pump from a 1989 ford f-150 with a 302/5.0 fit on a 1985 f-150 with a 302/5.0?
What year is the Mustang/Crown Victoria? Best of luck!
Q:hot water recirculating pump question?
particular you are able to. in certainty there's a recirculating equipment called a Polaris water heater which could furnish warm water for all your place carry desires and warmth your place too. the cost of operationg a Polaris equipment is extra cost-effective than an on call for warm water heater.
Q:My camper water pump keeps running?
I might be miss-understanding your question. If you have no water in the tank then the pump will run all the time because you won't build enough pressure in the system to shut it off. There should be a switch to turn it off manually. If your system has water in it and pump still won't shut off then it could be several different things: 1. Pump is bad and leaking internally... do you have good pressure at the faucet? 2. There should be a pressure cut-out switch somewhere near the pump. This switch should shutoff the pump when the ideal pressure is reached and prevent the pump from over pressurizing the system. Make sure it is not stuck closed. (May have to remove to test) Check for continuity across the terminals with pressure with the pressure on and off. If it doesn't' change... replace. 3. You could have a leak somewhere in the system not allowing the system to build pressure. 4. There may be a pressure relief valve somewhere in the system that is stuck open and dumping your pressure back into the suction side of the pump. Good Luck!
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:Does a Water pump have to stay running?
Most of the time when you use water a large amount the pump will come but should shut off after a reasonable amount of time. When the set pressure is achieved it will shut off. And when the pressure drops it will turn on and the pressure will drop when using water.
Q:My car squeaks every time I turn it on. But the belt is tight and I have a new water pump and alternator.?
Check closely, you may find that the pulleys are not lined up completely. Have you had the power steering pump replace? Very common to have the pulley not pressed on completely, causing the ribbed belt to not ride properly on the pulley, causing squeaks.
Q:velosity of water pump of dirrrent pipe like suction & delivery?
Q:2000 Chevy Impala with a bad water pump?
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.
