Electric Diaphragm Pumps DBY Series

This series of diaphragm pumps are the latest model at home.They are functioned to take out and suck in various corrosive liquid containing granules,Viscous,volatile,inflammable,explosive or poisonous liquid,procelain slurry,mashed fruit,flue,the reclamation of residual oil in tanker,temporary reversion of tanker,etc.The performance parameters of this series are close to that of German WLLDENPUMPS and American MARIO-WPUMPS.The components in contact with flow are made of stainless steel ,aluminium alloy and cast iron, while diaphragm may be NBR,viton,neoprene or PTEE.

DBY electric diaphragm pumps are driven by Y or YB motor,suction head between 3-5m,delivery head up to 30m,and flow between 0.5-20m3/h.

Flow Rate Range: 0.8-30m3/h
Head Range: 0-50m
Operation Temperature: -20℃-120℃
Working Pressure: ≤1.6MPa
Flow-through Material: Cast Iron, Aluminium Alloy,Stainless Steel

Q: Relationship between power and flow of sewage pumpFor example, how much power waste water pumps do 1m3/h and 100m3/h need?Best detailed listShow the relationship between power and flow: If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.

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?: If you're seeing the drip from just behind the pulley, the pump seal is probably leaking...while it may not be much now, it will only get worse, so take it to a shop for verification of the leak and replacing the water pump...

Q: the pump is pumping hot wtaer from the hot water tank around the domestic hot water system, i.e to taps and shower.: These pumps can have their own bearing or they may rely on the bearings in the motor. Most of these are anti-friction bearings that have a limited life. Also if the pump runs dry it can over heat and seize.

Q: I'm trying to convince my dad to get a 1984 Porsche 944 for $900. However, the car need a new water pump and I was wondering how much it would be to get the part installed at a shop. What would be a good estimate as I'm planning on going to more than one place. So included with the price of the part and installation is this a good deal? And is the car reliable?: Porsche 944 Water Pump

Q: I want to buy a tree spraying rig for my property but would like to know its theoretical capabilities first. The rig has a gas powered diaphragm pump capable of delivering 20 GPM @ a maximum pressure of 300 psi. The hose coming from the pump is 150' long and is 0.75in diameter. It has a solid stream nozzle that measures 0.1875in diameter. What would the maximum theoretical elevation that this setup could deliver a steady stream of water? The nozzle would be aimed at between 45 and 60 degrees from horizontal.: well water exerts about 1 atm pressure (15psi) for each 33 feet of depth so 300psi is about 10 atm meaning that your pump could support a column some 330ft high then figure what pressure you would need to make your spray effective and subtract 33ft per 15psi this is only a ballpark estimate losses in hoses will be significant

Q: Ok, so I have a 1997 3.8 liter ford mustang. I was driving home from work the other day, when temp gauge started to go up. I brought it to mechanic, and he said it was a bad water pump, due to bad antifreeze. So I am getting a new pump, and an antifreeze flush. My question is that since it overheated, will there be any damage to the engine? The temperature gauge never hit the red, and smoke never came out. I had to drive it for approx 15-20 miles when it started to overheat, and the temp gauge was bouncing from hot to normal.: All kidding aside, the 3.8 Ford engine was discontinued for a mountain of reasons. When the temperature indicator went into the red zone, you should have shut the motor off and parked the car just like it tells you to do in the glove compartment manual. Lets have a little primer on tour temperature gauge and why the needle was bouncing around: The electrical temperature sensor in one of the cylinder heads is a contact sensor. This means unless it has to touch the coolant all the time it will not send the heat information to the gauge reader on the dash accurately. When the electrical sensor in the cylinder head HAS NO COOLANT TO TOUCH, the dash gauge reads ZERO. In other words the hottest part of the engine was not being cooled all the time. Never drive anything anywhere unless the radiator is filled to the top when the engine is stone cold and the plastic coolant recovery reservoir is at least 3/4 filled when the motor is stone cold.. If the cooling system is leaking as fast as you fill it, TOW the car do not DRIVE IT. Cross your fingers and hope that the valve seats didn't fall out of the cylinder heads.

Q: I just got a new boat with a diesel engine and I don't understand why there is a coolant tank as well as a water pump? I think the water pump goes to the heat exchanger but what actually cools the motor - how does this stuff work?: Coolant can leak from plenty of areas. Without figuring out what style of motor you've got, can handiest bet. Hopefully it's not a cracked cylinder head. But if you'll see spraying out you have got to convey the automobile to a mechanic. Obviously you're going to run out of coolant quickly even though you preserve topping it off. And it is going to occur on the incorrect time and situation. The leak price will broaden because the motor heats up and expands.

Q: I will be replacing my timing belt soon. The dealer is suggesting that I also replace the water pump. Is that really necessary? When do water pumps normally go out?: Water pumps have bearings, some new cars use plastic impellers. Eventually these do wear out. As you paid all the labor to get at the water pump, might as well replace it with a new one.

Q: How do you remove the water pump from bmw m42 engine?: Follow the instruction manual Drain the water first then remove the timing case release the tension from the belt, unbolt it and remove.

Q: I am creating a project where I must pump water to a helmet. If you have any ideas, thoughts, solutions, diagrams, etc. please? thanks: your question is not clear, do you need to build the pump from scratch or you should find one? what is the water flow rate? how high the water need to go? what the helmet has to do with the problem? simplest solution will be to go to the store and buy small hand pump (for fuel).
