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 received a call from my daughter who said that the water pump was making a grinding noise. She sent a photo to me showing 0 psi on the gauge. I came home to find it actually working again but after running water straight from the pump I found that it is really rusty. What is this caused from? Our water was nice and clear! We've had freezing conditions here. Still doesn't explain the sudden rust.
it relatively is probably not appropriate. a threat that the sump pump and the nicely pump have been tied jointly and has a GFCI breaker interior the line. See in case you will discover a GFI it relatively is likewise tripped.
Q: Does a Insurance policy cover if your Well water pump burns out from power outage and breaks seal and burns motor?
You'd have to read the policy and see what it covers and what it doesn't.
Q: Does anyone know where to find small A/C powered submersible pumps, that operate at 20-25 psi? I can only find D/C pumps for ship use.I need one for running humidifiers and misters for large terrariums
From your question description, I'd use a condensate pump. They are about 30 bucks wholesale, so figure 50 retail. Look at one. I bet it's what you need. They are used on HVAC units. They have good head pressure for 3/4 lines. Even bigger. Your question has a lot of open spots in it. So, I'm answering the best I can. Hope this helps.
Q: Domestic pump automatic shut off the water, but also turn around, stop what happened?
You can find a water pump factory people ask, ah, Baidu, find a corporate website, many have online advice. By the way, a site called water industry navigation, pump manufacturers included a lot, and find it may be faster.
Q: new switch and new tank
Sounds like a bladder tank issue. The bladder gets potential energy when the pump fills the tank. When you open a faucet for water, the potential energy stored in the bladder will push the water out of the tank without the need of the pump coming on until the tank is almost empty. You should be able to rock the tank when the pump first comes on to see if it is light weight, as it would be when almost empty. If not then there's your problem. When the pump ends its cycle is when the tank will be at its heaviest. Again: The tank should be full when the pump is not running and almost empty just before the pump comes on. The water pressure would behave as you describe if the bladder tank is not functioning properly.
Q: how does a water pump work?
Water pump works by suction and lifting up the water to a desired level. The mechanism of pump to increase the hydraulic height/level of fluid. Example : The pump will pump and lift water from a 25 feet deep well and carry it up to fill a water tank placed on a 30 feet high structure.
Q: I was vacuuming up water from my basement I assumed was from the rain, suddenly water started spraying out of a blue pump at the base of my furnace, don't know what the pump does or why its spraying but its making an awful mess.

Q: I need to replace a water pump on a '95 3100 Pontiac Grand Am and am looking for a guide how to do it. Also, do I need to flush out the coolant or can I just put a pan underneath the water pump and let the coolant pour out when I take the water pump off? Thanks.
no you need to drain the anti-freeze out of the radiator. after your done you can flush it or you don,t have to. take the belt off, take the bolts out, clean the surface on the engine, put a new gasket on the new pump, put some sealer on the gasket ( both sides) place the pump on the engine, put the bolts back in and tighten them evenly, put the anti-freeze back in, put the belt back on, start it up and check for leaks.
Q: I got my oil changed yesterday and took like a 3 hour drive and back home and had no issues.. today I was at my work visiting and I noticed smoke coming from the engine [sort of more of steam] and a lot of smoke coming from the exhaust. The light on the gauge inside the car for the engine temp isn't working but all the other ones are. A mechanic told me it was a bad water pump, but I just want some more opinions. Or if the oil change could of effected that.. My engine coolant wasn't that low but a greenish liquid was really leaking from underneath the car.

Q: Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
