FAQ of Sewage Submersible Dewatering Centrifugal Pump WQ Series


1. Is it really necessary to fit a bleed valve for the boxes?

It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

2. If I increase the power of the motor, must I also increase the power of the inverter?

You must select the size of converter that allows maximum absorption of the electric motor.

3. Do you have pumps with grinders?

Yes, the WQ models.

4. How long is your warranty?

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:What is the current of the pump when it is started?
Just started when the pump current is 2-3 times the rated current is normal, so, the power is greater than the pump motor, many small factories in order to survive, the small motor will cut corners, produces motor burning phenomenon, and pump failure caused by load current is increased, and the pump flow rate exceeds the rated flow is a super current. General large water pump is the first to start the water pump, and then open the outlet valve, is to solve the pump just started when the ultra current problems.After excluding pump fault flowmeter check flow is beyond the rated flow, the excess can pumpslittle off flow control valve to reduce the current problems above are not dismantle the motor current of the motor itself over to see how to judge whether the motor has fault.
Q:How Do You Identify a Bad Water Pump?
bubles would be a bad thing commmon issue with the cavalier and sunfire is blown head gasket and they overheat big bubbles coming up in the tank is the sign of a blown head gasket and they always overheat then if no bubbles then thermostat is usually whats wrong in these cars. makre sure you bleed the air out of the black steel tube in front of the engine there is a bleeder screw on it also makre sure the cooling fan and relay work by unplugging the CTS sensor on the driver side end of the head, black oval shaped two wire plug takes a few seconds to kick on
Q:can i drive my car to a service center 5 miles with a blown water pump?
Probably not because most vehicles use a serpentine belt/drive belt to run the water pump and when the water pump goes the belt will most likely fall off. If you have an interference engine where the timing belt runs the water pump, then you could. It's not recommended, but I would do it if I couldn't do the repair myself.
Q:Regarding water pumping capacity of 15 stage 1 H.P. Borewell pumps?
thanks for th information
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!!!! the way you might want to replace the timing belt idler pulley as well....cause at about 190,000 the bearing will seize
Q:Can a water pump go out after hitting a deer?
It might If the water pump has lots of miles anything might make it go bad , Any accident will cause your car to act funny because it has not been disturbed
Q:Do i need a new water pump?
The radiator actual holds the water/coolant and the pump circulates the combination in the process the engine. Upon returning to the radiator, the water is cooled from air passing in the path of the fins of the radiator. The pumps activity is to circulate the combination to confirm that the nice and cozy water to relax for this reason, the engine is then cooled.
Q:How many kinds of pumps are there? What are the advantages of soft start?
The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.
Q:What could cause a water pump to break in a 3 year old car?
water pumps are cast aluminum normally...maybe there was a weak spot on the pump casting and it failed (but you would of overheated and had a mjor coolant loss that you would of noticed), or maybe the impellor is what internally failed and or the bearing on the shaft.. but yes normally water pumps last for awhile. I usually dont see replacement of water pumps unless doing timing belts and or high milage...but hell annything nowadays since everything seems to be made in China is cheap and poorly built compared to the old days...
