Q: I just opened up the water pump on my '86 cr250 and found it to be pretty dry. Found out why as soon as I threw some light on it. Yep, all but a TINY hole in both hose nipples (?) are completely gunked up in some nice light green/white crap.Does anybody know what this is? Okay obviously it's coolant, but why is it so dry? What causes it? My bike never quot;overheatedquot;, but there's very little travel room for the liquid. What should I do now? Clean it out and run new water through it?: Appears your cooling system has not been flushed for years thus the build-up of slime, (seems maybe even 'dry-slime'). The cooling system should be flushed clean, a new water pump and gaskets installed.

Q: What's the difference between a double suction pump and a single suction pump?: From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.

Q: How many kinds of pumps are there? What are the advantages of soft start?: Soft start is prepared, hard start is not prepared, the machine suddenly can not stand! Ha-ha

Q: I am having water shortage problems and wonder if there is more I can do to maintain the health of my pump motor , pressure switch , and diaphram tank , if I run one outlet in or out of house , it only takes another spigot being used or a toilet flush to cause the system to run dry .I then have to reprime pump to have water or pump will run dry until it overheats ,: This Site Might Help You.

Q: I have an 8 gpm pump at a depth of 170 ft, I am pumping the water 2000 ft in a 1 1/4 inch line. I need to know how many gallons per minute I am getting.: Use the Bernoulli equation, aka mechanical energy balance.

Q: The pump assembly and the pump are not a thing: Water pump components: stator, rotor, bearing, shell, sealing system, under their own consideration

Q: i have changed water pump,radiator and thermotast and it still overheat: (In addition to the above suggestions) Are the hoses good? Old hoses can collapse, blocking water flow. They should have been changed with the radiator, but not everyone does. Has the radiator fan been checked out to be sure it's working properly? If the fan isn't working properly, enough air might not get through to cool it down properly. Is it actually boiling over, or is the temp gage just showing it hot? I ask because it could be a faulty temp sensor. I'll assume that there's no debris between the radiator and condenser since the radiator has been changed out already. This should also mean that nothing is in front of the condenser blocking airflow.

Q: I know that the water pump is belt driven, so it would be easy to connect it to my bicycle. What I am wondering is if I can pedal fast enough to make it work. Does anyone know how fast I would need to pedal to operate the pump?: Mechanical water pumps will move water with any rotation, provided it's a sealed system and there are no obstructions. The flow rate will be determined by the RPM of the water pump. This is proportional to the pulley sizes of the drive pulley to the water pump pulley. 600 RPM for a water pump at idle is sufficient for the cooling system design and the engine heat load at idle. Without knowing the specifics of your application, it would be hard to tell how fast you would need to pedal.

Q: Dear friends, please let me know in most of the power plants recirculation line and balance leak off lines are provided for boiler feed water pumps and those lines are connected to Deaerator. Why?: The feed pumps for most power plants are multistage centrifugal pumps. They have a minimum flow requirement or the balancing forces of the various impellers are lost and the pump is damaged. A recirculation line permits a minimum flow to be maintained at all times. It goes back to the deaerator so the boiler feedwater is not lost. Note: many of these pumps have the recycle automated so it is only in operation at very low flow rates. The leak off from the balancing line is recycled for the same reason.
