5. FAQ
1> Can your pumps mount Eff.1 motors
Currently, only on request though this will shortly be a CNBM standard.
2> Are your pumps protected against dry running?
No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.
3> How can I get trained on CNBM products?
Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.
- Q:Does the water pump and the circulating pump belong to the centrifugal pump?
- They're all centrifugal pumps!
- Q:I have a submersible pump outdoors for the water to my house. Indoors is a holding tank and pressure gauge. It seems the pressure gauge keeps slowly declining down to 20. Then when the toilet is flushed, the gauge kicks on and climbs to 50. Then left alone for a while the gauge again declines to 20. Do I have a leak somewhere? If so , where? Does the ballast inside the holding tank need to be pressurized? If so, how where? I seem to remember years ago, my husband did something with a bicycle tire air pump. Makes sense? Thanks
- I assume you are saying that the pressure drops to 20 when no water is being drawn by any faucets, since that will naturally happen if water is drawn. Four things I would check - first look for leaky toilet float valves - the tank level will drop, and the valve will open periodically to refill the tank if the seal is bad on the float valve. Secondly, make sure you have a check valve installed on the supply line into the pressure tank to prevent water from flowing back down into the well. Third, you may need more air in the tank - I would put enough air in so that the off/on cycle was 60 seconds when one faucet was fully open drawing water. This would not be the cause of leakage, but it could increase the frequency of the 50 to 20 psi cycle. Fourth, I'd adjust the low pressure turn-on point up to over 30 vs. the 20 it is set for now - 20 is probably annoyingly low. Go for a gap of 20 psi from low to high - eg. 30 - 50 psi.
- Q:I suddenly have this rattle noise whenever the engine is running but it diminishes with speed. It almost sounds like spark knock but spark knock would get worse at speed. It could be the water pump. Would a water pump get louder with speed, or go away as this does? I feel a tiny bit of in-out motion in the shaft but not side to side. Car is a Geo Metro and does have hydraulic lifters.
- check your belt tentioner , ten-shun er. the computer keeps telling me i spelled it wrong
- Q:i have a jetta and would like to know how difficult it would be to do. I know its a german car this is why i ask. thanks
- The water pump is driven by the timing belt on that engine. You don't have to take the alternator, power steering pump, or the a/c compressor off, but you do have to make sure it is timed right. Not too hard to do, just make sure the marks line up. Good luck!
- Q:This was asked a year ago, so just wanted to see if there were any new answers for me. And any detail of how it can be a quot;do it yourselffix would be great. We are having major surge lately and the tanks pressure gauge reads 50 if that helps. Thanks!
- I take it you live in the country. This happens to me all the time. My problem is caused by fire ants, I'm in tx. Those stupid things are attracted to the electricity for some reason and will swarm on the pressure switch and cause it to burn up or malfunction. Go look and see if you have any bugs on yours. If not, well then i dont know. Replace the switch and that will cure it. It is not hard, i have done it myself many times.
- Q:I need a new timing belt and I'm getting that done soon, but my mechanic says that water pumps are usually replaced along with the timing belt at the same time. Does it really need replaced?
- yep replace at the same time better safe than sorry it'll cost more if it leaks later and you need to replace it
- Q:can bad water pump make car overheat?
- Yes because it what allows the engine coolant to flow to keep the car on the right temperature.
- Q:How hard is putting in a water pump for my 5-series on a 1-10 scale ?and how do i put it in ? details please !? i dont have a chitlon for it . ive worked a lot on this car and i do know some things about it, but not very car savy. Thank you !!
- What is easy for you may be hard for others, so I would not give the job any hardship rating. But the approximate job entails doing these...descriptions from viewpoint of person standing infront and looking towards the engine... a) remove fan blade with fan clutch by turning big nut clockwise (reverse thread) b) remove fan belt, then remove pulley attached to water pump c) remove radiator fan shroud if you can to have more space to work in d) put basin underneath engine to catch coolant and detach radiator hose connected to water pump e) remove 6 bolts holding water pump and remove pump f) clean surface of engine block to remove left over sealant/gasket g) install new pump and other removed parts in reverse order h) add coolant, bleed (using bleeder screws in thermostat housing and upper radiator hose), then top-off coolant to proper level marked on expansion tank near windshield. i) ran engine or roadtest, then recheck coolant level after overnight stay or when engine cools down.
- Q:94 f150,302 engine. the water pump comes with 2 gaskets. one behind a metal plate on the pump and another for mounting it to the motor. my question is do you have to use sealant of any kind on both gaskets or can you just bolt it on?
- Use gasket sealer. RTV silicone or whatever.
- Q:Why should the pump fill the air before running? What's the reason why the water doesn't go up?
- First of all, why should exhaust air, pump suction principle is the rotation of the impeller, pump water inside the throw out, and then let the inlet pipe into a vacuum. Then, under the influence of atmospheric pressure, the water pressure is pumped into the pump. Therefore, if the water is not filled, the sealing of the pump is impossible to pump the air inside the evacuation of high vacuum. In other words, do not fill the water, you can not smoke water. You can hear the noise in the pump when the water bubbles under the bottom vacuumThe water doesn't go up because it doesn't have enough vacuum!The reason 1 is because there is no water filling,2, because your pump and water vertical height higher than the pump itself suction stroke.3., the pipeline resistance is too large (including the pipe diameter is too small, elbow and so on)
