FAQ of Vertical Multistage Centrifugal Pump of QDLF Series

1. How 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. Do you have self-priming pumps?

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

4. Is it really necessary to fit a bleed valve for the boxes?

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

Q: The water pump needs to be able to pull up water roughly 8+ feet. Ideally the system should include a filter to eliminate the presence of jellyfish. I need the most cost efficient solar panels with wattage provided. The battery used would be something similar to a deep cycle marine battery. Additionally I must figure out the amphours. Does anyone know where I can look up previously constructed systems or my best method of approach. Whom should I seek help from? Any suggestions would be greatly appreciated. The price range we're looking at is around $1000.: Dude okorder / You can visit them there, its got more info, i recommend call them and talk to a specialist. Good luck with the sweet aquarium!

Q: My 2001 300M is behaving oddly. Occasionally it will gradually overheat after I have driven around for 15 or so minutes. Yes, occasionally. I took it to my mechanic who changed the thermostat and hoses. I then drove it on a trip on the interstate and over a mountain (140 miles ) It was fine with no signs of overheating. Then the next day when I drove to work in the city, the stop and go traffic had it overheating near the end of the trip. I've been able to keep it from going in the red by using the heater. After this happened most of the days, but not all, I took it back to the shop. He reported that the fans were working correctly and the only thing he could come up with is a weak water pump. He stated that when it did get hot, he was able to bring the temp down just by rev'ing the engine a little.Does that sound right? Any other ideas and how to test?: The only reason to replace a water-pump on such a new car is if the weep-hole on the bottom of the water-pump in-put shaft casting is leaking. If your upper radiator hose if hot when the dash temperature reached 195 degree's there is nothing wrong with the water-pump. Cooling systems plug when brand X antifreeze is mixed with the standard equipment, long life type. *Did your mechanic do an inexpensive *cooling system pressure test to look for external and internal coolant leaks? Is the radiator filled to the very top when the engine is stone cold? Is the plastic coolant recovery bottle at least 3/4 full when the radiator cap has been removed? Have you checked to see of the electric cooling fans are operating behind the radiator when the dash temperature reaches 205 degrees? It's less expensive to change the thermostat and radiator pressure cap than a non-leaking water-pump. An 11 year old car is do to have the cooling system drained flushed and *cleaned before having Fresh factory recommended ZEREX G-05 antifreeze added.

Q: So I need to make a human powered water pump... Does anyone know how to make one? Any websites that could show me would be nice.MORE DETAILS:The pump is on the ground...it needs to pump water from a reservoir into another reservoir that is two meters high and two metres across from where the pump is... The pump needs to be handheld too. What should I use and any good plans on how to make it?: The simplest manual pump is the lever-arm pump. This is just an elongated cylindrical reservoir, a valve casing, and a pump chamber in a linear arrangement. A piston within the pump chamber is connected to a link, and a handle which is used to pump the water. You can make a simple one by converting an ordinary bicycle pump. Attach an input hose to the air inlet, and an output hose to the pressurized air output for the tire. A good way to develop plans on how to make it would be to visit your local sporting shop or auto parts shop and look over their pumps. .

Q: need to know how to change water pump of my plymouth voyager its a 96 and motor is a 4.: This is the 2.4L dual cam 4 cyl. The water pump is spun by the timing belt. Get a manual and follow the instructions to change the timing belt and pump. Plan on taking several hours.

Q: What is the safety head of a pump? Why should a safety head be added?: The pump achieves this by providing sufficient energy to the liquid at the entrance of the impeller, and ensuring that the liquid remains liquid. This energy is known as the available cavitation margin, referred to as NPSH (A).If there is not enough NPSH (A) or energy, as soon as the liquid enters the impeller, its velocity is increased. According to Pohl's law, the pressure drops. A reduction in pressure will cause some molecules in the liquid to become gaseous, forming vapor bubbles.The performance of the pump will be lowered immediately and the bubbles will continue to grow until the pressure inside the pump causes them to implode.In brief, it is to avoid cavitation.

Q: Multi storey residential buildings also need to set up pressurized water pump room, direct water supply can not be?: Some water pressure is not enough, and since you are multi-storey, you need to add booster pump downstairs

Q: 300M head of 11 stage centrifugal pump with 22KW motor, empty (not water) current of 13A, the water into the pump, current up to 44A, open the outlet valve of the current rising to 100A, immediately shut the gate current is up to 170A, the motor stop. Without any problems, not on the impeller pump shaft is not clean the shell the balance sheet, no wear, bearing normal.: The description of the problem is very clear. Most of this kind of circumstance is overload, is also the outlet pressure is very low, the flow is greater than the rated value caused by the resistance can be adjusted by increasing exports or close the outlet valve, reducing the flow resistance increased by less than or equal to the rated flow. Lift is not an influencing factor.

Q: can a worn water pump make the car idle high while in park when driven for a long period of time......03 grand prix: The water pump is only an impeller and moves fluid through the engine for the purpose of cooling. With that in mind, no, it should have no effect. Suspect you have a vacuum leak that is causing your high idle, check for a high pitched whistle and when you find it, fix it.

Q: 89 Dodge van overheats, no water leak, replaced thermostat but still overheats.: this sounds more like a radiator problem, or possibly an electric fan, if there is on. Usually the water pump will lose the weep hole gasket on the bottom of the water pump and dump water when its running, but quits when you stop. A water pump bearing can start to sieze, you may notice temp fluctuating almost to hot, then drop back down. Take off the radiator cap when the vehicle is cold and start it up. let it idle until the thermostate opens. and watch the water in the radiator to see if it circulates at all as someone slowly raise the idle up to 2 thousand rpm, and rev the engine a few times, and see if the coolant momes across the radiator. It may be your thermostate is stuck partway, or the radiator is ready for a rebuild, they generally are good for about 20 years or so. I suggest using distilled or filtered water in your radiator if you replace it. There are many harmful chemicals in tap water, much more than people realize, and they can combine with chemicals in antifreeze and cause solder rotting electrolysis. By using distilled water, you minimize this risk and studies by major radiator companies have been proven to make radiators last a lot longer if a minimum amount of care is taken, like changing antifreeze every few years, and using distilled water as much as possible. I buy mine in the gallon jugs. and top off the overflow occasionally.

Q: I need a new timing belt and I'm getting that done soon, but my mechanic says that water pumps are usually replaced along with the timing belt at the same time. Does it really need replaced?: yep replace at the same time better safe than sorry it'll cost more if it leaks later and you need to replace it
