FAQ
Q: If I increase the power of the motor, must I also increase the power of the inverter?
A: You must select the size of converter that allows maximum absorption of the electric motor.
Q: Do you have pumps with grinders?
A: Yes, the WQ models.
Q: How long is your warranty?
A: Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications.

- Q:how do get the tub off the washine machine to fix the water pump?
- its under the machine
- Q:I would like to make a simple electric pump that can pump water. I would like to know how it works. I would be most thankful if you can provide me a link of an animated video on how motor works.

- Q:How to design its control circuit, to prevent it idling, what peripheral equipment do you need?
- The centrifugal pump can not be idle, idle will wear packing (packing seal, mechanical seal is almost not damaged) parts, also caused the seal ring, seal, etc. the balance disc wear quickly, and the temperature will rise sharply, causing damage; air transfer effects caused by transient overload voltage of the motor is large, if the motor can not automatically jump to motor will burn.Centrifugal pump mostly rely on the delivery of liquid lubrication and cooling seal of centrifugal pump, idling is empty load, is to open the inlet valve, close the exit valve operation can move, try reversing or empty load operation should be based on the inevitable time, pump specification shall prevail.
- Q:All water pump have diferent caracteristics, but it is imposible to overcome a certain hight...what is that hight and why?
- If you are talking about the limit on the suction side of a pump then the answer is about 34 feet. This is because due to atmospheric pressure that is all the water can be raised without the portion at the bottom of the column starting to vaporize. 14.7 psia (atmospheric pressure) equals 33.9 feet of water.
- Q:37KW how many contactors does the pump need to start directly?
- First of all, you have to see what voltage you use If 380V then current per KW is about 2A, if it is 660V per KW at about 1.1A, then it is the starting current is 3 to 7 times for the starting current, but for the moment, 380V voltage: 37*2=74A 100A on the line, 660V voltage: 37*1.1=40.7A 63A on the line.
- Q:Ok, I took my '93 Jeep Cherokee Sport 4.0L in to get the serpentine belt replaced, as the old one had snapped. They told me that the water pump had locked up and that's what made the belt break. The thing is, I had to get the radiator and water pump replaced this past summer and I am wondering what might've made my water pump lock up since it is new. The Jeep has a lot of miles and I'm slowly having to fix a lot of things, so I'm trying to be sure that I don't fix the pump just to find another problem. Also, the repair place told me the water pump looks brand new, so I know that it was definitely replaced, but should I contact the place the fixed the pump and radiator and see if there's some sort of warranty on the pump?
- I would check for the warranty for your water pump. I had an 89 GMC pickup and I kept blowing alternators and pulling front cover bolts that supported the power steering pump.. Your belt even snapped!?! Mine split. These are all symptoms of the serpentine belt being too tight. My automatic belt tensioner was at fault. Your water pump has probably got the belt around the pulley about 3/4 of the diameter. That equals a heavy load on the bearings resulting in them failing and locking up. Get yourselt a new belt tensioner this time.
- Q:do I need to replace it again ? How hard is it to change the water pump? Any Idea where on the internet I can download a free maintenance manual or replacement instructions ?
- Since okorder , click on Repair Info on the left, select Vehicle Repair Guides, and then input your car model. All the instructions you need are in there.
- Q:changed the thermostat. it overheats but cools down a heat bar or two idling at stoplights. i filled up the coolant reservoir when i changed the thermostat, drove it about 2 miles(engine was already up to temp when i started) and it overheated. drove it two miles back going about 35-40 and it never went above normal but was still overheating. checked the reservoir and it was empty. stuffed a hose in it and plugged it up with a towel to force water in to see if it was leaking anywhere, no leaks. while running with the rpms up the top hose is easy to squeeze. makes me think water pump. but if i go over 45 it over heats makes me think clutch fan.
- well if it is the water pump you will have a small hole ( tale tale hole ) and it will be leaking water to let you know its out. and clutch fan there will be alot of play i have seen people stop them with there hand but i dont advise it
- Q:i changed my fuel pump and now my car wont turn over....any help? maybe starter?
- From the info you give, I would have to say, MAYBE!
- Q:94 f150,302. my pump is still leaking after doin the job twice. its a new pump, the first time i used the red silicone between pump and plate,both sides of gasket,and the housing on the block. leaked. then did it again with high tack gasket cement and still leaks. i cleaned all metal both times with brake clean before installing. same with thermostat housing,small leak. ive done 100s of pumps over the years,no problems, so please no rude remarks on mechanical ability. what could it be? it leaks up front of the motor above the crossmember where ya cant actually see the leak,its not a freeze plug. bolts are torqued. any ideas ? thanks
- It's not the pump that's leaking. The water ports to the pump pass through the aluminum timing cover, over time the aluminum corrodes and leaks between the block and the timing cover. You need to remove the whole works and replace the timing cover, may as well do the timing chain since you're in there.
