FAQ

  ◆Are CNBM pumps available in DIY stores?

Yes, currently, we’re available for DIY stores all over the world.

  ◆Where do I have to send pumps for service?

You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

  ◆Are your pumps acid-proofed?

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.

  ◆Can your pumps mount Eff.1 motors

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

Q:Water pump belongs to power equipment or mechanical equipment?
Mechanical equipment, right?. The motor is only transmitting power to the pump, and no other device is available.
Q:Hit and Miss Engine Water Pump?
A horse and a half won't do much. You would be better off with a hydraulic ram type pump if you can get about a 10 or 15 foot fall before the ram. It will pump about 4 or 5 times the height of the fall, but in small quantities. It will run 24/7 without gasoline, so it will fill a tank over a long period of time. The railroads used them during the steam era when they had huge water towers out on the plains.
Q:Alternator belt and water pump leakage relations?
Depends. On older vehicles they used multiple drive belts for the different components (my '88 Caprice had 3 belts), but most newer vehicles only use 1 belt called a serpentine belt which drives multiple components (my '00 Dodge Ram 1500) If you lose your serpentine belt it will set the battery light as the alternator is not outputting the correct system voltage, and since the same belt drives the water pump then yes the car will overheat. It's dangerous to keep driving like that, most newer cars have aluminum heads which will warp when they get tooooo hot = expensive repair
Q:Water well pump, always on??
i had the same problem... twice. first time was due to a break in the well line. second time was a faulty precharged water tank. i was able to insert smaller soft plastic pipe into the old line, avoiding the backhoe. the second fix was to replace the tank. you do have to watch it tho, i melted my old pump motor due to a brown out. now that i think about it, your impeller could be worn , and the pump cant make pressure. good luck.
Q:what r the signs water pump is going out on 2000 ford focus zx3 2.0l zetec dohc? thanx in advance.?
Do your cooling fan(s) operate? One of the common problems with these cars, is for the cooling fan resistor to burn out, causing the low speed cooling fan not to work when commanded by the PCM to work. When this happens, the engine will overheat. Regarding the water pump itself, is relatively simple to access. However, the engine mount needs to be removed in order the gain clearance for the pump pulley to be removed, and then the pump itself. Check the green with black striped wire, and the green with red striped wire leading to the resistor first though. It is secured to the cooling fan shroud by a simple plastic lock clip. This part is far simpler to access than the pump. Hope this helps.
Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
The empty transfer of the centrifugal pump causes dry grinding, and the pump is overheated and seals out.Frequency control cabinet can be used to set their own frequency required job requirements, the external need is contact, is the pressure gauge
Q:What are the components of a water pump being used in a car and how does it work?
An automotive water pump consists of a steel shaft with an impeller (like a steamboat paddle wheel) on one end and a pulley flange on the other. The shaft spins on bearings located in a cast iron or aluminum housing. The housing has internal passages to allow the water to enter the impeller cavity and exit, often to a tube like structure (part of the housing casting) to which one of the rubber radiator hoses attaches. How it works is simple. Water present in the impeller cavity is confined and pushed to the outlet by the rotating vanes of the impeller. The rotation of the pump is usually driven by a belt powered by a pulley on the engine which turns a second pulley mounted to the pumps pulley flange. The characteristics might include things like, is the pump self priming or is it self lubricating? In an automotive system the answer to both questions is yes. To evaluate a pumps efficiency you would want to set up a test rig where you attach the pumps outlet to a long hose and use it to fill a calibrated container (one gallon, five gallons etc). Then with a stopwatch you can either time how long it takes to fill a gallon container or you can measure the volume of water pumped in a minute. Either way you will get useful information you can use to evaluate the pumps efficiency. You should repeat the above test at different engine RPM's to discover if the pump has peak efficiency (or lack of efficiency) at a particular RPM or range of RPM's. Finally, if you do this experiment for real be sure you add water as fast as you pump it out so you don't over heat the engine and damage it. Have fun.
Q:Integral Problem: Water is pumped out of a holding tank at a rate of 4-4e^-.14t liters/minute?
Water is pumped out of a holding tank at a rate of 4-4e^(-.14t) liters/minute. Lets call that function w(t). So if we integrate w(t) over a time period that will give us the total water removed over that time period. So lets integrate it from t=0 (time when pump started) to t=60 (one hour later): ∫ w(t) from t=0 to t=60 ∫ w(t)=∫ 4-4e^(-.14t)=4t+(4/.14)e^(-.14t) evaluated from 0 to 60 ∫ w(t)=4(60)+(4/.14)e^(-.14*60)-4(0)-(4/.1... ∫ w(t)=211.435 liters removed If the holding tank began at 1000 liters and 211.435 were removed... Remaining water=1000-211.435 ***Remaining water=788.565 liters***
Q:Difference between Air pump and Water pump?
Air Pump For Water
Q:Where is the water pump located on a 2002 Mercury Cougar?
Leave the water pump alone! It sounds to me like your gauge is malfunctioning. Every so often an electrical gauge will fail and give strange readings. It could either be the sensor that reads your coolant temp or the gauge body itself. Your car cannot go from overheating to fine while stationary at a red light. Take it to a shop (that specializes in electrical, they're out there) and tell them the temp gauge is acting wacky. If you INSIST to know the location of your water pump...should be on the passenger side of the car mounted to the engine. It's either driven by an accessory belt or the timing belt, I can't remember at the moment. Here's a trick also. Water pumps are designed to leak when they fail. See if you can find coolant spilling out of anywhere a few ounces at a time. Good luck!
