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:instaling a water pump on 1998 sunfire,?
dont need to tighten until good and snug torque is critical on head bolts and bearing cap and rod cap bolts etc
Q:Is it economical to use a water pump with pressure switch but without using a pressure tank?
All that will do is cause your pump to burn out sooner. It will run WAY more often without a tank. The tank allows for a 'range' in your pressure, in other words, the pump will fill the tank to 30 psi, but will not kick on again until the tank gets below a certain level, say 20 psi, at which point it will pump it back to 30 and cut off again. Without a tank, the pump will run whenever you draw water.
Q:1994 plymoth grand voyager leaking anti freeze is it the water pump?
poss there is a pipe that runs under the intake! with seals on the end!
Q:Mazda b2300 keeps Overheating- Already put new Thermostat & Water Pump! What can it be?
Have the radiator wiped clean out. My Mazda truck radiator did a similar ingredient, and that i trust that you've a similar difficulty. in the experience that they could't clean it on the radiator shop, you're able to replace it.
Q:Replace the water pump on a 1992 Pontiac Sunbird LE?
The best thing you could do is maybe run to a library and they might have a Chiltons or Haynes repair manual you can make some copies of, check it out and decide for yourself, but a timing belt is a pretty involved process, not so much for a water pump.
Q:Efficiency of Hot Water Circulating Pumps?
Depends on what is considered efficient. Is running the circulating pump efficient on the hot water end, but not on the electricity. To me a circulating pump is best efficient when you add a return line back to the water heater via the cold water input. Also needed in this routing is 2 flow control units, 1 at the end of the bathroom return line prior to the cold water input. And 1 above the bathroom return on the cold water line. Then by running the circulating pump for 1 minute per hour you will have hot water almost instantly. Or just cap off the hot prior to the sink an add a instant hot water heater just for the sink I would of first tried pipe insulation, or even a pipe wrap with a heating tape to keep the pipes warm.
Q:Whats wrong with my car? replaced water pump and runs weird.?
Ive seen this before. u replaced the water pump, which means u drained the coolant, replaced the pump, and filled it back up again. When u filled it back up u created big air pockets in the coolant system. Small air pockets are always in the system, but wont cause a problem. Big air pockets cause the engine to idle rough, like its misfiring. Then when u go to press on the gas it stalls, or it wont rev past a certain point. Ive had this problem myself a few times, replacing water pumps and lower radiator hoses. About the best thing u can do is just let the car run and idle for an hour, maybe even 2! Then rev it when its still parked at a higher RPM, just to flush out those pesky air pockets. I know it wastes gas, but thats what i think the problem is. Air pockets are something that most ppl dont think about when they drain and refil the cooalnt components.
Q:Replacing water pump and heater...?
You need to get a second opinion from a knowledgeable friend or family member. When you say water pump , do you mean the well pump or is it a pump connected to the furnace that helps cycle hot water through radiators in the house? Please get a second opinion , maybe a friend or family can recommend someone who can help you.
Q:Choosing a manual water pump?
There are very small rotary water pumps designed to be driven with hand-held electric drills. These pumps may be purchased in some hardware stores or farm supply stores. One could be adapted to a bicycle- type drive. Small pumps have about a 50% efficiency so you would need to produce sustained muscle power applied at around 150-200 watts to achieve 75 -100 watts of effective hydraulics. Applied watts = (GPM) (PSI) / 1.277 million (eff.) Where eff. is as a decimal. Edit : A 3/8 drill will pull about 280 watts. I can do 200 watts on an exercise bike, but not for long. I am a 79 heart patient, so you can probably do better..
Q:Will installing an upgraded water pump void warranty?
A water pump... being directly tied to the engine's systems in several ways would give the manufacturer more ammunition to say it caused and defect or failure in the engine. Unlike an air intake that is a static part and is only tied to the vehicle's aspiration. It would be a gamble on your part to install the upgrade.... But perhaps an acceptable risk? Look into why you feel you need the upgraded water pump and determine if that need is worth the risk of voiding ther manufacturer's warranty.
