FAQ

Q: Are your pumps acid-proofed?

A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: 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.

Q: How can I get trained on CNBM products?

A: 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: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q:Well water pump kicking on?
No problems. It just means that the check valve in the pump is leaking off slightly and the pressure is dropping down to kick the relay in. As long as it doesn't do it every few minutes when water isn't being used, you have nothing to worry about. If you have a facet with a drip, it will do the same thing.
Q:Hartell solar water pump question ...?
OK, well your question is a bit confusing and I am not sure if it is because you don't understand how your system works. Your hartell pump pumps water. It does not produce heat. Your water heater heats water. It is a backup to your solar panel system. If on the other hand you have a heat pump as a back up source of heat this could be an entirely different matter and you are best at providing a model number which should be stamped on the part. We need to start again. Is your system for solar hot water or for general heating? Is it a system in a cold climate where freezing is an issue. Is it a pump down system or a system that circulates antifreeze in the solar loop. The reason all this is significant is that if you are paying a lot in electricity then something is not working. The first question has to be is it a design problem, a mechanical problem or an operational problem. You may need more hot water storage or more solar panels, you may need to replace parts, or you may simply need to turn the right valves (This would be the case where you have a grounding loop to keep the solar panels from overheating in the summer.)
Q:How do you check the water pump on force 85 outboard.?
There should be with muffs even if the impeller is bad check the thermostat or drop the foot and check the impeller.
Q:Is my cars water pump broken? Squealing noise..?
Coolant from water pump can leak on the belts and cause a squeal. So get some belt dressing to stop that. All things can be fixed with cans from auto stores. Fix a flat is good stuff too.
Q:how do you change the water pump on a 96 3.5l dodge intrepid?
in time is correct....but if you are really good you don't need to pull of the balancer....although not recomened you can fold the belt behind it if you need to but the proper way is to take it off.....hay desperate times call for despirate measures!!!!....by the way you might want to replace the timing belt idler pulley as well....cause at about 190,000 the bearing will seize
Q:if water pump is working should lower rad hose to thermostat be hot, it is cool and spongy!?
get your vehicle up to operating temps and runs your hand along the core of the radiator from top to bottom. If it's cold at the bottom and hot at the top, it's plugged... Also I see where you bleed the system, might wanna check it again... air pockets are stubborn... Last but not least, have a C.O. test performed at a local radiator/automotive shop... This will tell you if you have a blown head gasket
Q:Replace water pump in a 1999 mitsubishi eclipse gs?
what variety of noise? additionally, what do you mean by skill of is it solid? They valuable looking autos IMO and that they are able to be solid if dealt with. do no longer assume to make diverse ability from the 420A engine although.
Q:Replace Water pump, big noise came out, then jump time and engine died?
You have a good case for small claims court, but you'll have to prove the facts in court, not here on yahoo. 1) Prove that the first shop changed your water pump. (I think there's a good chance that mechanic did, indeed, mess up the timing.) 2) Get something in writing from any subsequent, licensed mechanic who thinks the timing was changed. At 100,000 miles, there's a fair chance your timing chain could have been old, needing replacement, but if the first guy replaced the water pump, that seems the likeliest culprit. Worse, I hope you didn't ruin the motor. Sometimes when your motor is out of time, you can bend a valve or put a hole in the piston. Better get your motor checked by someone who knows what they're doing then consider your options- small claims or the first mechanic's insurance company. If you talk to the insurance company, you should have a lawyer do the talking. Good luck!!
