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.
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:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
1, frequency conversion water pump is based on ordinary water pump. The so-called common pump means without any automatic control device of the pump, only the pump head and the motor and a base. The power supply is switched on (default: 220/50Hz or domestic power single-phase three-phase 380V/50Hz) run off, stop. Ordinary pumps do not refer to a particular type of pump, can be centrifugal pumps, pipe pumps, vortex pumps, multi-stage pumps and other pumps commonly used.2, the variable frequency pump, is supplemented by a one-way valve, pressure tank, inverter, constant pressure water supply controller, sensor, valve or electrical components in general based on the composition of water pump with automatic function, and automatic constant pressure frequency conversion water supply device. The input power of frequency conversion water pump can be single phase 220V/50Hz or three-phase 380V/50Hz, but the motor of frequency conversion water pump is usually three-phase. The incoming line is a single-phase 220V variable frequency water pump. The motor is a three-phase 220V motor, the input line is three-phase 380V, and the pump motor is three-phase 380V.Two, the differenceAccording to the definition above, the difference between variable frequency water pump and ordinary water pump is obvious. The main differences: first, the frequency pump has automatic function and constant pressure; ordinary water pump does not; second, variable frequency water pump is a unit, the price is much more expensive than the ordinary water pump.
Q:When is it necessary to replace the timing belt and water pump on a 2001 Mazda Protege?
That could have either the 1.6 liter or 2.0 liter engine. My information shows that if you have the 1.6 liter, at least you don't have to worry about bending valves against pistons if the belt breaks -- you'll just be stuck out on the road until you can get it towed and fixed. Not so with the 2.0 which is an interference engine. So if you DO have the 2.0, pay attention -- you don't want an expensive breakdown! You're on borrowed time at 75K. For both engines, Mazda recommends that you replace the timing belt every 60K miles. Gates (a major replacement supplier) seems to think these belts will go 105K. Since it's a factory belt, stick with 60K. As for the water pump, it's often one of those while you're already in there sort of things when you're doing a timing belt. 60K makes it a tougher call, especially with the better quality of water pump bearings and seals. If your interval were 80K ~ 100K as is true on some cars, I'd say go for it without blinking. As cheap as it'll be (it's really just the price of the pump), and it was my set of wheels, I'd do it anyway, even at 60K, if it needed to be pulled to do the belt.
Q:Can i run a fan and water pump while charging deep cycle battery?
You may have to do some math. The 80 watt panel is only 80 watts at peak sun on a 75°F day at the equator. Chances are you will have something less than 80 watts to work with. But you can add up all the hours of partial sun to get an equivalant number of peak sun hours. An example would be a few hours in the morning and evening at partial power and a couple of hours at solar noon at nearly full power may give you 5 peak sun hours worth of light. 5 psh x 80 w/ps = 400 wh Your supply may have 400 watt hours worth of power per day. You state that the fan is 12v dc but what is the wattage? It could be a little 12v dc fan out of a computer or it could be a huge 12v dc fan out of an RV. What is the power requirements of the water pump? Is it a little 12v dc one for a foot tall decorative fountain or an industial 3 phase pump for a well? To charge the battery you need a voltage 120% higher than the battery voltage. 12v x120%=14.4 v To add up your loads convert them all the use to dc watt hours per day Here is an example to give you an idea of how to play with your numbers: Fan 12vdc x 1.5 A = 18 watts, use this for 5 hours your load would be 18w x 5hr = 90 watt hours Pump 120 vac x 2.5 amps = 300 watts (The AC will need to come from an inverter. The inverter has a certain amount of loss. How good it does the job of converting dc to ac is know as it's efficency. Lets use 90% to be safe) 300 watts / 0.90 = 333.4 watts, use this for 1/2 hour per day 333.4w x 0.5hr = 166.7 watt hours The 90 watt hours + the 167 watt hours = 257 watt hours per day. This would leave about 140 watt hours to put into the battery. Yes it would be best to use a charge controller to protect the battery from overcharging if the pump and fan are off, or from draining the battery too much if the fan or pump stays on.
Q:water pump for hunting cabin?
I had a jet pump to run my whole house on my farm. It was placed in the basement, but it could be in a back room, too and they are pretty quiet these days. Does it freeze inside the cabin? I assume not. having it inside means if you have trouble even in freezing weather you can work on it in comfort. The end of the pie into your water tank will need a foot valve to keep the pipe filled so you don't have to prime the pump ( not a handy thing to have to do all the time). Other than that, the system is operated with electricity and a pressure switch which is settable. It will not run all the time this way. Not sure anymore but, for example the switch might be set to come on at 50PSI and shut off at 125PSI. You can tell by the switch or get a recommendation from the store where you buy it. (see pictures in link) Menard's sells these and department workers are trained to answer all your questions about installation, parts, and what you need,etc.
Q:i am looking for a water pump?
Flow? Head? suction pressure? Type of pump if that matters to you? You'll get better suggestions if you provide as much information as is relevant.
Q:How can I find out how to install an auxiliary water pump on a 2003 Jetta 1.8 Turbo?
If its a 2003, you should still have a warranty on the powertrain unless its over 50,000 miles, or so. If indeed the water pump is leaking, you'd be foolish to leave it go; the timing belt can get wet, the belt and jump time and cause engine damage, that would be very expensive!! Save your self a lot of grief later by going ahead and replacing the water pump now; if you feel you're not up to the job, then have someone who knows VW's do it for you. Also replace the timing belt at the same time. An attempts to try and do a temporary measure will be met with an expensive result; a leaking water pump can also suck air into the cooling system and cause a hot spot, which could blow the headgasket, especially on a turbo model VW. Sorry, to tell you this, but its better to fix it now and save money, time, and pain later. I spent 25 years on/off in VW dealership service departments from 1980 till Dec of 2005. A car nut.
Q:why is my truck overheating after a new thermostat and water pump?
id say its the radiator after all what ya replaced. have it checked out at a shop. before ya do though ya might do a complete flush of the motor and the cooling system. might be a blockage in a water jacket in the motor. ya can buy the flush kit at any parts store, its simply a T that ya splice into on of the heater core hoses,hook up a water hose,turn heater on, and wait with the engine running. if theres any blockage it will spit and sputter till its pushed out with the water pressure. let it idle till clear water comes out then drain and add coolant. try this first with water only and if it doesnt solve your problem id say ya need a radiator.
Q:What are the export pumps packed in cartons?
Upstairs said the basic right, but only limited to the domestic, export also put the pump's wooden case (frame) into the carton.
Q:How do you build a water pump?
There are a number of different types of pumps (and some overlap between types, too). A suction pump basically sucks water up. This might be a piston pump, or a venturi pump (or some other types). This type of pump raises water up by lowering the air pressure above the water, and letting atmospheric pressure push the water up the tube. Suction pumps can't pull water up more than about 32 feet (because that's how high atmospheric pressure can lift a column of water) but they have the advantage that the pump can be located at the top of where you want the water (rather than down where tie water is). A Lift pump basically uses mechanical force to raise water upwards. This could be a chain of buckets, or an Archimedes screw, or a bubble-lift pump. All these pumps need to have at least part of the pump down at the water level (with the exception of the bubble lift, which is kind of a unique design). The most common water pumps are centrifugal pumps. These use a set of spinning vanes to pressurize the water. Water comes in at the center, and hit spinning vanes; these shove the water outward through centrifugal force, and the outlet pipe is at the outside edge of the circle. One other interesting type of pump is the hammer pump. It's sometimes used in remote farming areas, because you can use the energy of a running stream to pump water high up a cliff. In a hammer pump, you let water flow through a relatively long tube. The tube has a vertical pipe near it's end. You let the water run through, and then suddenly close off the end of the pipe. The momentum of the water (combined with the fact that water isn't very compressible) can force a shot of water very far up the vertical tube. Hope this gives you enough to search for on the web!
Q:Does a Water pump have to stay running?
No this is normal when you flush it should come on
