Pneumatic Double Diaphragm Pump Product description

QBY air operated double diaphragm pumps not only can transfer the flow liquid, but also can transfer some uneasy flowed medium, with the merits of self-priming pump,diving pump, shield pump, slurry pump and impurity pump etc.

  1.It’s unnecessary to pour the drawing water, the suction lift reaches 7m height, the delivery lift reaches 70m length and the outlet pressure≥6kgf/cm²;

  2.Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. The damage is very less to the pump while exchausting the slurry and impurity.

  3.The delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment (the pneumatic pressure adjustment is between 1-7kgf/cm²) ;

  4. Pneumatic Double Diaphragm Pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The conveyed medium can’t be leaked outside. Thus it will notcause the environment pollution and human body safety danger while exhausting the toxin and flammable or corrsive medium.

  5.No lectricity.It’s safe and reliable while using in the flammable and explore places.

  6.It can be soaked in medium to work.

  7.It’s convenient to use and reliable to work.Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters,the pump will not be damaged caused by this. Once over-loading, the pump will auotomatically stop and possesses the selfprotection function. When the load recovers normally, it also can start automatically.

  8.Simple structure and less wering parts. This pump is simple in structure, installation and maintance. The medium conveyed by the pump will not touch the matched pneumatic walve and coupling lever etc. Not like other kinds pumps, the performance will drop down.

  9.Gradually because of the damages of rotor, gear and vane etc.

  10.This pump needn’t the oil lubricant. Even if idling, it has influence to the pump.This is a special characteristic of this pump.

Q:How Do You Identify a Bad Water Pump?
I agree with f100-supersabre's answer. And here's some more to ponder... Chances are your water pump is just fine. When was the last time, if ever, you serviced your cooling system? And by that I mean dumping the old anti-freeze, back flushing the system to include the heater core and refilling with fresh coolant. If the answer is never then your radiator is probably toast. The internal passages are clogged and it does not dissipate heat effectively any more. Another thing to consider: the electric cooling fan(s). How many does your car have? With one fan, the fan will run: Anytime the A/C is switched on. When the tempurature sensor in the cooling system rises above the preset value of the sensor. With two fans: One will only and always operate when the A/C is switched on. The second will operate in response to the preset value of the cooling system sensor. Check the operation of the fan or fans. Turn on the A/C, the fan or one of the fans will turn on. With one fan only, turn the A/C off and let the car idle until the the single fan turns on in response to engine temperature. With two fans, you can let the A/C run and let the car idle until the second fan turns on in response to engine temp. If the fans don't work as they should, the first place to look is for a blown fuse. High amp fuses are found in the engine bay in a seperate fuse box ...look for this ..pop the lid and check the fuses. A map for the fuse purpose/location is usually found under the lid. If the fuses look okay, then it may be a bad sensor or it might be a bad fan. The sensor is usually less expensive and easier to swap out than the fan assemblies. Your cooling system, if has been neglected, may need both a radiator and some work on the fans if they prove less than up to snuff.
Q:What are the signs of a bad water pump?
i think this might be work on how to check if the water pump is in bad condition, first run your car for about 20 min or 30 min until it became hot. then look at your water pump while your engine is still running. if you noticed that there's a steam rolling off then it needs to be change or replace. or if you see that there's a leak. what you need to do is to look at it while the engine is running. then you will know if it is in bad condition.
Q:Looking for help picking a water pump.?
I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.
Q:Replacing water pump and heater...?
true. is this hot water heater and pump? rarely do both go bad at once. A hot water heater is 2-300 and install is maybe 150. get an HVAC tech for an opinion. don't take one person's word for anything in which they stand to make a profit.
Q:what tools do i need to remove the fan on my BMW and get to the water pump?
You need to get the large nut lose. It holds the fan/fan clutch to the water pump shaft. After you get that off it's all down hill from there.A large adjustable wrench will work on the nut but you will need to keep pump from turning to loosen it. I think it may be left hand thread. It is not on real tight. The book will help on this one.
Q:Is it economical to use a water pump with pressure switch but without using a pressure tank?
A pressure tank acts to mellow out the surges inherent in the action of the pump. Without a pressure tank, the service life of the pump is diminished. Think of using a garden hose at full volume at the end of 50 feet of 1 pipe. That works out to 17 pounds of water moving at a high speed. When flow stops the 17 pounds of water has a tremendous amount of energy that has to go somewhere. It is better if that force goes into an air cushion at the top of pressure tank rather than into the vanes of the pump.
Q:How many kilometres should a water pump be changed on a toyota hiace 5l engine?
Toyota Hiace Water Pump
Q:What is the difference between a fire pump and a living water pump?
1, fire pump is actually divided into many kinds, such as car, fire hydrant system, spray system, etc., life pump is also, the distinction between them is sometimes difficult to tell the exact. Simply put, the fire pump in its design must meet the corresponding fire requirements, such as pressure, speed, work adaptability, etc., specific requirements can be found in "national standard GB 6245-2006, fire pump Fire, pumps""2, the same function of fire water pump, its price is relatively stable. I personally feel that we must find more manufacturers to understand the reasons for the price difference, and then make a choice.
Q:does water pump sealers work?
If your talking about the water pump for a car it doesn't have any pumps those would be the radiator pumps that are connected to the water pump and transmission which keeps the radiator and transmission at a temperature that keeps the vehicle from over heating. If you have a overheating car and a mechanic told you your water pump has a leak then sorry you would have to replace the water pump but just don't go to a popular mechanic for that because it can get really expensive do your research and find you someone with a garage it cheaper because the part itself is not that expensive it putting it in that cost lol. Hope this helps.
Q:where is the water pump located on a 1995 honda civic?
on the engine, in the front
