Usage of GDL Series Vertical Multistage Centrifugal Pump 
Mainly used in high-rise buildings life, fire control, heating and air-conditioning systems, suctioning large stores, hotels, office buildings and high-rise buildings, industrial and mining enterprises, municipal engineering water supply and drainage, fire sprinkler system feedwater and boiler feed, chemical process make-up water and so on.

FAQ

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: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q: If I increase the power of the motor, must I also increase the power of the inverter?

A: You must select the size of converter that allows maximum absorption of the electric motor.

Q:Do you have to replace the water pump when you replace the timing belt on a 2004 Chevy Aveo LS?
He is saying that, because the water pump is driven by the timing belt and you SHOULD replace it while you are in there. Why pay twice down the road? Sure the belt can be done without doing the pump, the fact that he said the pump will break when doing a belt is complete bullsh*t though. There is no need to do anything to the pump when changing the belt other than taking the belt off the pulley. That's it. Generally, I just add maybe .5 hrs to the labor for the belt when doing the pump also, DOUBLE doesn't make any sense whatsoever. Unless he is worried about pump BOLTS snapping from CORROSION (that may be it) when removing the actual water pump, that is the only thing that can possibly justify doubling the labor, they may be in water jackets in the block. He should, however, make you aware that that is a possibility and not automatically assume that will happen and charge you for it. Depends, if they are careful with the removal, it should just add another 20-30 minutes to the timing belt job. Either way if you turn down the pump and they are telling you it will still break(?), go somewhere else. I work on cars everyday and would never charge someone an additional 300 dollars off the bat assuming the bolts will break. There are tricks to prevent that as well (penetrating fluid/PB Blaster). Generally if that does happen, one maybe two bolts would break tops and that still doesn't justify the additional labor... Hope that helps....
Q:radiator problems.....or a broken water pump?
Codes won't tell you anything and there's no such thing as a thermostat fuse. this can be several things, but it's not likely the water pump. what fails on a water pump is the bearings, a failure that would cause this type of problem would be a frozen water pump and if that were the case, the belt would squeal like crazy and break, as it move but the w/p didn't. a bad w/p will drip coolant from the bottom just back of the pulley, there is a hole there that leaks when the bearings are bad,, but that won't cause a overheat. If the coolant is low, top it off, with the car cold into the rad and the overflow bottle. Change the thermostat, it could be frozen shut, but it is unlikely. if you rad is that shot, you could change it, but the most common cause of this sort of problem is a warped head and/or a blown head gasket. A mechanic can check for this, but take it ot one you trust, as this is about a 1,500 dollar job either way, you have to pull the head to fix it. Running it with low coolant, unfortunately can cause this. if it's not this than the rad is plugged up, but if it just started happening, and it temp gauge maxes out all of a sudden with a full coolant tank, it is likely the head gasket/head. It can also be a cracked block. Sorry to be the one to give you the news..
Q:H2o pump?? how u know when its not working?
Water pump may have three types of failure: 1. Leaking shaft seal You know by a. puddle under the car, b. low coolant level, c. ultimately - overheat 2. Shaft bearing failure You know by excessive noise, play in the shaft, ultimately - leak from the seal (see 1) 3. Turbine itself breaks. This is a rare case, and the only one that represents no working condition. The engine immediately - withing a few minutes - overheats.
Q:What is the purpose of providing recirculation line & balance leak off line for a boiler feed water pump?
The feed pumps for most power plants are multistage centrifugal pumps. They have a minimum flow requirement or the balancing forces of the various impellers are lost and the pump is damaged. A recirculation line permits a minimum flow to be maintained at all times. It goes back to the deaerator so the boiler feedwater is not lost. Note: many of these pumps have the recycle automated so it is only in operation at very low flow rates. The leak off from the balancing line is recycled for the same reason.
Q:can a 2000 lincoln water pump fit a 2001 lincoln?
We need to know what model of Lincoln you're working on. The water pump from an LS 3.9L isn't going to fit the 4.6L or 5.4L of a Aviator or Navigator. You must be more specific. The part numbers show it's the same water pump for a V8 2000-2001. I bet if looked further, it's probably the same pump up to the end of production on 2006. Don't forget to bleed the air from the cooling system when you complete the repair job!! You'll definitely have ovrheating issues if it isn't right. MAke sure it's the V8 (3.9L) pump and not the V6 (3.0L) pump.
Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?
The high and low level values are set back.
Q:what is foot valve in pump?
For the best answers, search on this site https://shorturl.im/awBzE A very good foot valve will cost about $20 then it will be the cost of a service call, here we charge about $70 but depending on where you live, how deep the valve is and where its located the price maybe different, and the cost maybe more on a weekend too. Giving quotes for this is not really profitable for service companies, so if you are not prepared to do it yourself then you will have to pay the service call rate. A good reputable company will arrive at your home and give you an approximation on what it will cost, but remember once you call them there you will probably have to pay the service call rate, if you are running tight on money call around and ask the rates but remember that this is a weekend and most companies will be running a small crew and might take time to answer your call. The other option is since you have changed the pump yourself why not just change the foot valve your self? Have you primed the pump after replacement? To replace the valve the pipe that runs to the bottom of your well must be pulled up and the valve is on the bottom of it, its a simple matter of removing the old one and replacing with new the big job is usally the pulling up of the pipe.
Q:Integral Problem: Water is pumped out of a holding tank at a rate of 4-4e^-.14t liters/minute?
Water is pumped out of a holding tank at a rate of 4-4e^(-.14t) liters/minute. Lets call that function w(t). So if we integrate w(t) over a time period that will give us the total water removed over that time period. So lets integrate it from t=0 (time when pump started) to t=60 (one hour later): ∫ w(t) from t=0 to t=60 ∫ w(t)=∫ 4-4e^(-.14t)=4t+(4/.14)e^(-.14t) evaluated from 0 to 60 ∫ w(t)=4(60)+(4/.14)e^(-.14*60)-4(0)-(4/.1... ∫ w(t)=211.435 liters removed If the holding tank began at 1000 liters and 211.435 were removed... Remaining water=1000-211.435 ***Remaining water=788.565 liters***
Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
There are no special rules for the time being.
Q:Why should we pump water into a pump when the country uses a pump to pump it?
This is the water diversion, after the discharge of air, the pump started, under the influence of atmospheric pressure in order to absorb water.
