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: My friends car is a 1997 jeep wrangler. The belt broke and she took it in to get it replaced and they told her metal from the pully that broke got into the water pumpand they have to replace that to? WTF? it makes a squealing noise and they want to charge her another 300 for that! we just don't understand how that could be if the pump isn't even leaking?: Well like someone else has mentioned the squealing usually comes from the round pulley that the belt rides on maybe in your case some metal has damaged the idler puller on your water pump and that would definitely give you a consent squeal. the price to replace your water pump is very excessive the part at any over the counter parts store ranges from 30-45 dollars the labor too do this on a jeep is 2.2 hrs @ the shops hourly rate which also varies but 45-55 hour isn't unreasonable... so on the high side of these figures it should be about 120.00labor 45.00 parts so a bill of $165.00 would be more appropriate......but if you don't make the repairs knowing it still has a problem you might void any type of repair warranty on your current repairs already completed...hopefully this has helped you somewhat...jimboz

Q: What are the quota items for the complete pump installation?: It can be divided into the following sections:1. pump installation platform, to obtain concrete and reinforced section (if any)2. anchor bolt installation: cap construction reserved bolt mounting holes of the anchor bolt installation hole grouting taking, (may be incorporated into the 1), and the damping piece related item;3. pump installation: installed in the installation of fixed item taking pump, check the wiring and debugging section, the first cable.The above is only a rough expression, the specific problems are flexible.If you still don't understand, you can contact me.

Q: water pump went out how do we find it where would it be located?: On okorder /... When you're filling up the coolant, you need to bleed the system to get the air out. 2 bleeders, one right around the corner from the pump, and another back by the Thermostat housing. The 3.1L V6 in your Malibu doesn't use a timing belt, but a chain. Just take the serpentine belt off, take the pulley off, and there's the pump. 4 bolts for the pulley I think, and 5 for the pump. Easiest to loosen the pulley bolts, then do the final tighten later, while the belt is still on. Torque the Water pump bolts to 89 inch lbs. (10 Nm), and the pulley bolts to 18 ft. lbs. (24 Nm)

Q: What does the pump lift mean?: The pump head is the parameter you must know when you buy a pump, that is, the height of the pump.To buy a pump, I think the Heathrow pump is OK. I bought it earlier this year. It's not bad yet, but the quality is pretty good.

Q: It DID start after the Water Pump was put on. And i have not yet been able to detect a vacuum leak. The quot;whistling noiseseems consistent with RPMs, and the quot;dieseling(run-on) stopped in all but a rapid succession of 5 quick ~1-minute start/stops when the engine was fully warmed.. then it minorly ran-on.Could i be driving myself nuts over a Water Pump sound, and if it IS a Water Pump bearing, do i need a new Water Pump?1984 Chevy Camaro. 2.8 V6 carb'd 165,000 miles Auto.: Yes the water pump can make that noise even when new. The pump will keep working until the seal fails. You will see water pissing out of a small hole under the pump and that is when you replace it.

Q: I would like to change the water pump myself but do not have a repair manual.: For the best answers, search on this site https://shorturl.im/avT4K More than you can afford. It's got dual overhead camshafts and the water pump is in with the timing if I'm not mistaking. Because of this, you have to disassemble the entire front part of the engine. You also have to bring it to top dead center, mark the camshafts, remove the timing belt, and a whole lot of other stuff that you just don't want to mess with.

Q: The role of impeller in water pump: The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.

Q: I put the new water pump in and the metal tube that goes to the heater hose it is hitting the wheel that holds the 3 belts that goes onto the water pump. why is it doing that. got the right pump. I have a 1986 firebird V6. any ideas?: the wheel that holds the 3 belts that goes onto the water pump is called the pulley. You may need to check the old water pump for a spacer between the pump and the pulley. If the tube is not straight you may need to turn it some. Verify that you are not putting the pulley on backwards. Although the auto parts store claims that it is the right water pump, they may be wrong, and may have given you the wrong one. To find out lay the side that goes against the engine on a flat surface next to the original to see if the height is the same for the shaft that the pulley goes on. If you cannot solve this you may want to take both water pumps, the pulley, the bolts that hold the pulley on and the tube for the heater hose to the auto parts store and ask them. Often they have some experience in automotive repair and may be able to show you...the main difference between them and us is they will be able to see the parts, and we cannot.

Q: my heater in my 94 ford ranger went out about a month ago today i flushed the heater core and it worked for a while and started going out again after i was driving for 15 to 20 mins. the hose going into the heater core was warm but coming out wasnt. could it have gotten clogged again or could it be something else.: You need to find the Heater Core water valve.. That's the part that works as the TEMP. Control.. Water Pumps don't die slowly..and leak tremendously.. === Sometimes the Water Control valve(seizes).. So..you need somebody to throw the TEMP Lever back and forth..until you can find the valve location.. You may see the cable moving--put not acting upon the valve.. Usually the valve is shot--spraying a lubricant at it won't do anything.. It needs to be removed--too be worked upon.. Also check all the heater hoses for wear--damage--you may need to rebuild that part of the system.

Q: Work done in water pumping?Water is to be brought from a well 60 meters bellow ground level to a tower 10 meters high, once there the water falls freely on a 5000 liter tank. A submerged pump 10 meters under water level and a two inch diameter pipe is to be used. What is the work done by the pump when 2000 liters have been served to the tank; what is the power of a pump selected to do this work in 20 minutes.: Power_W = (Mass_kg * Gravity_m/s/s * Height_m) / time_s Where: Mass kg is 1kg/l of 2000 liters Gravity is 9.81m/s/s Head is 60m + 10m (height). The suction head is ignored because the pump is submerged. In practice there is some suction head due to intake restrictions like pipes, check valves, strainers. The time is 20 minutes in seconds. The work is the energy used in the time allocated, which is: power * time in seconds, which is watt seconds = joules. Not needed here as it is in the formula above. Power is the rate of doing work. The depth below water is not really relevant except for pipe losses which increase the head slightly. The flow is 2000 liters/20 minutes = 100 l/min. This can be used with the head of 70m to determine the pipe restriction, which amounts to a pressure drop representing extra head added. It will indicate whether the pipe is too small (excessive head added) or whether the pipe is overkill (no head added). You can find on line calculators for this, e.g. search pipe resistance flow on line calculator. I am guessing a 2 inch pipe has little loss at this flow. This is the so called water power. It is the output power of the pump. The pump may only be 50% or so efficient, so the mechanical power delivered by the motor needs to be greater by this ratio. The electrical input power to the motor is greater again to allow for motor efficiency. This might be 60-90%. In practice the efficiency of pump and motor are determined from user manual or specification of the actual devices with the actual loads (head and flow).
