FAQ
Q: Where do I have to send pumps for service?
A: You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.
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:This is a brand new water pump and we used plenty of gasket maker. Does this year of f150 need the back plate that comes on the water pump?
- I doubt it. It's almost certainly the gasket.
- Q:I am trying to replace my old water pump with a new one. I have the quot;special tooland everything but i just cant get the water pump to come loose at all. Any suggestions would be helpful Thanks
- When you mean it wont come loose, do you mean you cant break the bolts loose or is the pump stuck on the motor like glue? If the bolts are stuck, try spray them with penetrating oil and let it work in for about 30 mins. If the pump is stuck, use a narrow putty knif, gently tap in between the pump and the block, and pry it off, then clean the mating surface completely to ensure the new pump seals properly.
- Q:A water pump that consume 2kW of electric power when operating is claimedto take in water from a lake and pump it to a pool whose free surface is 30 m above the free surface of the lake at a rate of 50 L/s. Determine if this claim is reasonable.You have to show the minimum power required is 14.7 kWand i can't get it.
- A liter of water mas a mass of 1Kg. How much work must be done to raise 50 Kg of water through a height of 30 m? You can say: Work done (W) = potential energy gained (mgh), Or you can say that Work done is the weight force (mg) * the distance moved against the force (h) Either way, W = m * g * h where m is the mass; g is the acceleration due to gravity {9.8 m/s?}; h is the height W = 50 * 9.8 * 30 = 14700 J If you need to do that amount of work in one second, that's a rate of working of 14700 J/s A joule/second is a watt. Minimum power required = 14700 W = 14.7 kW
- Q::) approximatley how many and where would you buy them :/ :) x peacce dudes
- LIKE A BAJILLION!!! You can never have too many water pumps. You buy them from the water pump store on the corner of 85th and Broadway, next to the Wachovia Bank branch across the street. P.S.: Africa is NOT a country. LMAO!!!
- Q:I have a new water pump with its new gasket to be installed tomorrow. Do I still need to apply a gasket sealer (blue RTV silicone) on the gasket itself? If I do, do I need to apply it on both sides of the gasket? Thank you.
- It doesn't hurt. You just need it on one side. It is best to put it on the water pump and let it dry a bit then put the gasket on. The silicone will hold the gasket in place so you can put the water pump on a little easier.
- Q:It is known that it takes an hour to pump water, and also to know the head. How does the pump power need to be calculated? What's the formula?
- Power P (kw) =9.81*Q (second cubic meter) *H (head, unit m) / efficiency;The efficiency can be found on the pump nameplate or sample.This is the rated power, if the head down, the flow increases, the power will increase, so the actual motor power is often much larger than this calculation.Generally buy pumps are equipped with motors, manufacturers can refer to the same model or similar models of motor power.
- Q:Would a bad water pump make a whinning sound when the engine is reved.....ive checked everything off as to why my car is running so hot and im down to the water pump.....ive put a New thermostat....no leaks anywhere.....no oil in coolant....no coolant in water.....no white smoke.....Fans do turn on.....new colant and i bleed the air out.....but the engine is still running really hot....my car calls for about 13 quarts of coolant but upon refil it took only about 4 quarts...... .. . uld this be signs of my water pump failing.....the pump is not leaking and when i took the housing off the water pump and turn the engine the blades did rotate...but at a higher rpm with the car together i heared weird noies kinda like a whinning sound from the water pump.....1995 Oldsmobile Aurora194,000Northstar 4.0 V8
- Your cooling system holds as many quarts as your manual says. The radiator, block, cylinder heads, heater core and all hoses are figured as 100% empty in your manual. You probably drained just the radiator instead of flushing with a Prestone or Peak flushing T spliced in the heater hose return line and draining the block. You're down to two more things. Clean the cooling system with two 33 oz. bottles of Prestone Super Radiator Cleaner and follow the instructions on the back of the bottle to a T. It's a lot of work to do it correctly and understand why you're doing what your doing as you work along. If the water-pump isn't leaking from the weep-hole underneath the output shaft there's not a darn thing wrong with the water-pump. Finally, haul out your wallet and buy a new radiator after uou've cleaned the system. With the best of care automotive radiators crap out after 14 years of use. The internal cross tubes build up with corosion, calcification and rust.
- 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:I was wondering if water pumps make any noise when they are submersed? Also, my pond is quite small and I don't want to scare my fish with a noisy pump. Thank you!
- i've got efficiently used that pump for ten years, recirculating water interior a fountain. it quite is not submerged and is thoroughly silent as long as you do no longer permit debris accrue on the impeller section. I double filter out the water earlier it is going into the pump. that's wiped sparkling via unscrewing the bleed-valve on the top and letting the debris be cleared. you could take it aside there, too, yet take care re-assembling because of the fact the o-ring is comfortable.
- 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
