Description of QW(N) -Type Submerged Dredgepump

QW type submersible sewage pump is developed based on imported advanced technology abroad. It has the advantages of high efficiency, not easy to enlace, no clogging, auto-coupling and auto-control
The advantages of QW pump are its small volume, compact structure and high efficiency, with products more than 15kW. It can detect the water leakage, overheat, overload protection. And as the requirements of user, an auto-protection control cabinet which has liquid level control shall be equipped.
Installation type of QW type pump has auto-coupling installation and movable installation.
QWN type submersible sewage pump is developed based on QW type pump, absorbing advanced technology abroad.

Application Area of QW(N) -Type Submerged Dredgepump

QW type pump is mainly used in urban construction, industry, hospital, building, hotel, restaurant and so on. It is used to transport silt, urban sewage containing solid granule and long fiber.
QWN type pump is mainly applied in municipal engineering, steel plant, power plant, mines and some other wear-resistant sites for discharging sludge and waster water containing solid particles.

FAQ

Q: Are your pumps acid-proofed?

A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q: How can I get trained on CNBM products?

A: 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.

Q: Are your pumps cheaper than those of your competitors?

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

Q:Why does the GB/T3216 specify the pump performance tolerance as positive and negative?
Tolerance coefficient is due in the manufacturing process, will, so each pump products are possible shapes and sizes do not conform to the pattern of the situation, and ensure the test results in the value (operating point) when compared, should be allowed to have a certain tolerance. It should be noted that these tolerances are only relevant to the actual pump and do not involve test conditions and measurement uncertainties.If the pump at a certain working point (the same lift) standard (Design) flow of 20m3/h, the actual flow of 22m3/h, indicating that the pump in the design process has unreasonable place, resulting in waste of power. Deviations from the manufacturing process usually have no positive deviation.
Q:Changing a water pump in a pt crusier?
The water pump is driven by the timing belt on this motor. If it is not done right, you could cause serious damage to the engine. Actually $800 to change the pump and timing belt is reasonable. To lower the price further you could negotiate buying your own parts. Good luck.
Q:where is the water pump for a 2001 chevy malibu?

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 many kilometres should a water pump be changed on a toyota hiace 5l engine?
Hi strange you say this it seems like when ever a timing belt is changed on a toyota the water pump is always an issue, i was warned that the same is true on my land criuser that the water pump may need to be replaced when the timing belt is changed.

Q:TDH what units are present in the pump parameters?
Answer: TDH stands for single pole double suction horizontal chemical process pump, suitable for conveying clean or containing micro solid particles of ultra low temperature or high temperature liquid medium, is also particularly suitable for conveying strong corrosive medium. All facilities for horizontal installation are available.Mainly used:Petroleum smelting plant, petroleum conveying equipment and pump used in petroleum deep processing devicePump for coal chemical processPumps for water and desalination systemsPumps for fuel coal fired power generation equipmentSewage treatment and environmental protection pumpStructure characteristics:Pump in the horizontal opening, suction and discharge pipeline is located in the lower half of the pump body. The disassembly and replacement of the wearing parts and the replacement of the rotor parts can be performed without disassembly of the pipe.Double suction impeller, high efficiency, good cavitation performance, axial force is basically balanced.Rigid axle shaft and bearing, double end support, small deflection, small vibration, low noise, oil lubrication of rolling bearings with oil ring, constant level oiler automatic control level, and can get automatic compensation, radial thrust ball bearings back-to-back bear residual axial force.The sealing ring of the shell is provided with a stop and a step, and is arranged on the pump body and the pump cover, so that the assembly and disassembly are convenient.
Q:How much is it to replace a water pump?
i just replaced my water pump on my jeep, the whole water pump kit was about $59.99 with lifetime warranty, most mechanics charge alot to do it, i did it myself, you just need a water pump, gasket, coolant draining pan, bottle of coolant and the procedure is pretty easy
Q:can i drive my car to a service center 5 miles with a blown water pump?
its possible. i dont reccomend it, but if you do, get a couple or few gallons of just water, depending on how big your radiator is, and keep an eye on your temp gauge, if it starts going up, shut off your car, wait 5 to 10 minutes, carefully open the cap on your radiator, and put water in it untill it fills back up. i had a busted water pump i drove 20 miles on everyday for about 3 days untill i had time to fix it, it wasnt a bad leak though, and that still sucked, i would honestly just pay the small amount for a tow truck for the 5 miles.
Q:how to make a mini water pump?
I doubt that your motor is waterproof. You would do better to just purchase one of the many fountain pumps all ready available at many home improvement centers or online. They are water proof and have the pump and motor all in one enclosure.
