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: I took out the thermostat, filled coolant level to upmost, my car still overheats, it doesnt leak ne where.How can I tell if the water pump is workin?
water pumps are generally built with a weephole ( a spot where if coolant enters the internals in the pump it will leak out externally) it could be a blockage in the system somwhere, radiator, engine block, or heater core
Q: How can I do a pressure test on my 350's water pump. Some one suggested I do it to make sure it needs replacing.
What makes you think the water pump is bad? If it has a bad seal/bushing then it will be leaking coolant out of the bottom eyelet on the water pump itself and you would be losing coolant, if its overheating then that could be air trapped in the system and may just need to be flushed or ran for a little bit to circulate the system. I would check these options first but if you want to pressure test it just start the vehicle and squeeze the upper radiator hose to see if there is pressure on the hose. I hope this helps you my friend.
Q: Okay so earlier, I went to go test out my water pump and all on my 66 mustang 302. And I got it up to normal operating temp, and had the rad cap off. I gave it some gas, the coolant level didn't go down, instead it came out the rad pretty badly. I've been having overheating problems, and I have no leaks, i just replaced the thermostat a few days ago, it didn't help. I haven't seen any leaks around the weep hole on the water pump, or noises. Other than a belt that does need to be tightened a bit, you can hear the belt squeling a tiny bit. So do yall think it could be my water pump?
there are several problems that can cause this one is a stoped up radiator or a lower radiator hose thats soft
Q: Yesterday morning I was looking under my hood and I noticed that I was leaking water. It looked like the leak was coming from the water pump.I had to get to work, which is close by so I topped off the radiator and went to work. When I got to work I looked under the car and saw no leaking. I figured the radiator had ran dry although the car hadn't overheated, After work I started to fill the radiator to get home. I saw that I had leaked a little fluid but not much. I topped it off and picked up my son then went home. No overheating. No leaking. Today I've ran several errands and I've had no problems. What do you think was going on with my water pump yesterday?
you do not purchase an element like that from OKorder. you purchase it from autozone or a save the position you are able to take it again if it truly is no longer the right one. bypass to the autozone website, save your vehicle it is going to pull up what's accessible for that area grant you with a cost. then you actually can bypass purchase it on the shop. i love their web site too because you are able to type in 'sensor' it is going to pull up each and each of the sensors for that vehicle. That facilitates at the same time as attempting to be sure out what it would want to be. Btw, you want to scrape the engine block floor incredibly good with a razor blade a putty knife in all likelihood use some type of solvent to sparkling it or you'll remorseful about it. do no longer purchase a remanufactured water pump both. you'd be redoing it in 5 yrs. Oh i meant you may want to in case you hardly ever rigidity the vehicle, yet no longer in case you rigidity it commonplace.
Q: If the water pump does not get water to pump, will it be burnt out? If so, then can it be fixed? And if it doesnt get water to pump, what exactly happens to it?
Jennifer said it so rated her, it's called air spin and she told you the rest
Q: need lincoln 01 water pump and radiator do 2000 parts fit an 01?
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: Yang Chengtai big, the pump power is too small, the water pump will be bad?
No, only when the operation of the low lift point is super power (burning motor), high lift point operation, low efficiency, small amount of water, or even no water. For example, a nominal 10 meters pump, flow rate of 10 square / hour. The actual lift 15 meters, the water pump is small or no water. The actual head is 5 meters, traffic may 20 square / hour, this time may exceed current, the motor may burn.
Q: So I have a 2.4L chrysler cirrus. The water pump appears to be not working(pumping the fluid through) and the car over heats. They location is on the side since its a front wheel drive car. I have both a Chilton and Haynes manual and they both say i need to loosen the front engine mount and lower it. Thats about it really..Now i was wonder couldnt that mess up something. I dont plan on doing this myself but i would like to know how. Is it possible for the engine to fall out? Might sound stupid but im not sure how all that will work so i would like to know. Thanks -Joe
No worries.. there are sometimes four mounts on a transversed engine. (front wheel drive) two at the top, on the frame rail supports, or on the inner fenders, these hold most of the weight of the engine and trans, there are normally two more, but I have seen only one used in some models, these are used to support the engine from twisting or rock on the upper mounts, due to tork or braking forces of the engine. removing ether of these mounts will not effect the support of the engine, as the two upper mounts do all the supporting of the drive-train. Loosening the front mount is safe, just remember that once the front mount is removed, a certain amount of swing or free play will result, as the engine will now just be hanging from it's top mounts, and will hang freely from it's center of gravity, so expect it to move some when mount is loosened or removed, be careful not to get your hand, or other part of the body, pinched or caught when the weight shifts. go slow.. and nobody get hurt... with the possible exception of a few busted knuckles.
Q: me and my friends are contemplating going on a road trip.almost 20 hours of driving.but we dont have a water pump, can you drive without one?
you can drive 10 to 20 minutes with out one and then walk the rest of the way
Q: I have a '97 Grand Prix with a 3800 V-6. There is a single bolt on the left side of the water pump that is directly behind the power steering pump pulley. How do you get the PS pump pulley off? I pulled a tricep trying to get this thing loose, and I'm no further now than when I started on it. Can anybody give me a tip on removing the pulley or the whole PS pump? I have a brand new water pump that I can't get on because of this fine piece of design by the brilliant engineers at GM!
here is a step by step on how to re move the pump is a lot easier than tring to pull off the pulley plus it will not come off when it on the engine there is no room for thr puller.
