Introduction of Air driven diaphragm pump (QBY) 

This series of diaphragm pumps are the latest model athome. they are functioned to take out and suck in various corrosive liquid containing granules, viscous, volatile, inflammable, explosive or poisous liquid, porcelain slurry, mashed fruit, flue, the reclamation of residual oil in tanker, temporary reversion of tanker, etc. The performance parameters of this series pump are close to shat of German WILLDEN Pumps and American MARIO-W Pumps. The components in contact with flow are made of stainless steel, aluminium alloy, cast iron and engineering plastics, while diaphragm coulde be NBR, viton, neoprene and PTFE(F4)

Characteristic of Introduction of Air driven diaphragm pump (QBY) 

1. No Leakage 
2. Pump body material: Cast Iron, Aluminum Alloy, Stainless steel, Engineering Plastic, etc. 
3. Diaphragm material:  NBR, viton, neoprene and PTFE(F4), etc.
4. QBY pump has two diaphragms, the compressed air come to the pump body to drive the pump in the constant action of sucking and releasing, so it can pump the liquids easily by this principle. Also it is very safe in dangerous environment since it has no electric motor. 

Performance parameters of Introduction of Air driven diaphragm pump (QBY) 

Max solids can pass: 10mm. (according to different types) 
Capacity: 0.8-40m3/h, head: Can reach 50 meters. (as per water) (special demand can be negotiated)

Q:Our CRN series pumps used in the 414V 480V 60Hz 60Hz power supply, what would be the effect? Is not the head can be reduced, there is no water pump and lift what voltage relationship?
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:Car is ford taurus 98.The car had some problems including overheating as thermostat was bad so was was not working. i drove it 25 miles to garage (i had to stop once because too hot to let it cool), i brought it to Ford who replaced the thermostat. Now they tell me some bits of thermostat broke and they need to replace the waterpump and want $620 for it. The other repair were also extremely expensive and i want to bring it to another garage 1.3 miles away on flat road.-1- is it safe to drive 1.3 mile with no water pump or should iget it towed?-2- should i have to pay for the water pump or is it ford's fault if they did not remove the bits of broken thermostat before reconnecting new thermostat to hose ? Can i prove that the pump was working when i came in if i drove 25 miles with it ?Thanks for your help.
Ford people are boneheads for making you pay for something THEY broke. And what does the thermostat breaking have to do with the water pump? All they want to do is suck you in for every penny. All services are warrantied for X months/X miles. If they broke it, they are responsible for it. As for driving 1.3 miles without a coolant, I would not reccomend it unless you wanna cook eggs on your engine. Seriously though, You'll do more damage to the engine running without a coolant. Then you'll need new pistons, fry the oil in the engine and probably need a whole new engine. Have it towed, it's cheaper in the long run. Don't take it to Ford ever again. They're sufering and in the red, they need to make money some way, screwing people is the way to go.
Q:1995 Ford Contour GL, 2.0L 4Cyl- three water pump failures. I bought the car in 2000 [49,000 miles] and in 2003 [116,000 miles] a leak from the weep hole area was repaired by replacing the pump. In October, 2005 [164,000] another leak from the same place was again repaired by replacing the pump. Just over two years later now, 196,000 miles, and today it's leaking from the same area. Any idea why this would happen? Each time I've replaced the pump, I've not been able to see any damage to it. People talk about impellers breaking, but they've always seemed intact. Maybe it isn't a pump failure so much as a leak for some other reason? Since purchase, the car has run what appears to be hot, in that the temperature gauge, when at operating temps, is only a tick or two from overheating, but since it's in the normal range, I've always assumed it's just a faulty thermostat. It's never overheated except for when the leak has sprung up.Any thoughts? :)
When all these pumps were replaced, were they new pumps or remanufactured pumps? It makes a difference in the quality and longevity. Spring for the new pump, preferably from Ford. The impeller problem was on the 2.5 liter V6 Contour, they are plastic and tend to scatter under load. As far as the gauge goes, it is normal on the four cylinder Contour for the hand to be between the M and the L in normal on the gauge. All of the 4 cylinder Contours are like this and the vehicle is not overheating. There is a TSB from Ford concerning the gauge, the TSB number is 98-21-3, the dealer can pull it up and let you look at it.
Q:The water burst how to repair?
The general water burst positions for the pump body, pump cover, if not very serious welding can be used to trap, at which point the attention electrode material, most of the water pump are cast iron, so the welding difficulty is not small.If it has become deformed or has split into parts, replace it.
Q:What are the commonly used tools for repairing water pumps? Mainly for civilian 220V submersible pumps, self-priming pumps. How much is the spare parts ready for use?
Because had done a mechanic, and relates to a pump, not including motor repair, commonly used tools: pliers, pliers, adjustable wrench, wrench, screwdriver, bench drill, multimeter, electric iron, Lamar, hammer, ruler, chisel. Commonly used parts: bearings, impellers, screws, terminals, lubricants and so on.
Q:Standard said that the fire pump should be certified by fire water pump, fire water pump and living water pump what is the difference?In addition to the brand, the same function of the pump, the impact of its price factors? Please advise Master ~ ~ ~ ~ ~ only feel so hard ah
The biggest difference between a fire pump and an ordinary pump is the performance curve".Fire water pump is tangent pump, that is to say, when the flow rate varies greatly, the lift head changes little. If the flow of ordinary water pump changes, head changes will be great.
Q:I have an 1982 El Camino 305 small block and am having troubles with determining if it is the gasket or the pump. I can't quite locate a leak, but it seems to centralize from the water pump and drip down the hose to the radiator. After my engine gets hot, which mind you my temp light has never turned on, and I shut of my car steam rolls out from behind my pump. I think it is the pump and please be it so. (Easier and cheaper fix. Replacement with a inexpensive part XP.)
Most likely it is the water pump... Probably leaking from the weep hole at the bottom of the pump and coolant is running down the lower hose. Head gaskets blowing on a small block Chevy is pretty rare unless you have ran it HOT!, which you have said you have not done. Use an inspection mirror and look under the pump just behind the pulley and see if the coolant is coming out of the weep hole. Small block Chevy water pump is inexpensive to buy.. Good luck
Q:4--6 inch deep well pump head? How much per hour out of water?.
Best answerLift pump is the location of the outlet is high, such as wells 5 meters deep, you put the pumping pipe on the bottom, the pump is placed in the vicinity of well, then, the head is 5 meters, the water power how much you buy depends on the pump, the greater the power, the faster the water pumping. The greater the party...
Q:I'm planning to install a water pump using electric generator from a very long distance going up from a cliff
if it is powerful enough to power the pump then yes.
Q:I just replaced my water pump.fixed.. A week later I've been noticing he might of over filled it because.were the coolant goes.steam comes.out.the little.while plus water.. And.before.I.started my.car I noticed.it was all empty now and my.engine sounds like a mini diesel when it runs.. What's the deal? And I.already filled it up with coolant again
Anytime you replace your water pump. You should replace the thermostat and gasket. Also check the upper and lower radiator hoses to see if either one of them are collapsed.It wouldn't hurt to replace the radiator cap.
