Product Overview of D series Horizontal Multistage Centrifugal Pump

Our horizontal multistage centrifugal pump can be applied for transporting clear water or liquid with physicochemical property similar to that of the clear water. There shall be no solid particle, abrasive material or suspended solid containing in the liquid.
Particularly, this multistage centrifugal pump can be used for delivering hot water, oil corrosive liquid or medium containing abrasive material through special employment of material, sealing mode, or cooling system.

FAQ

Q: Is it really necessary to fit a bleed valve for the boxes?

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

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. Either the delivery documentation or the invoice must be provided to prove delivery date. In absence of such documents, the production date appearing on the product label may suffice.

Q:How can you restart a corroded well water pump?
the problem with the pump not running will be the motor only.....most likely the motor rotor has rusted to the winding core of the motor ....soak it down with wd40 on the inside ...should be vent holes to spray wd40 in...try to find some way to turn rotor ....on some pumps there is a screwdriver slot on the end of the motor...if it still wont run take it to shop
Q:Water pump belongs to power equipment or mechanical equipment?
It's mechanical equipment!
Q:Adjust belts and change water pump on 02 Accord?
The water pump is driven by the timing belt. I do the water pump and timing belt with the pulleys and tensioner for around $600. If the drive belts are making noise try dusting some talcum or body powder on them. Don't use belt dressings, they never work.The timing belt should be replace around 90,000 miles so if that hasn't been done you should have it replaced or you will bend all the valves when the timing belt jumps or breaks. That's a 14 year old vehicle and the timing belt needs attention.
Q:how do you fix a washing machine water pump?
its under the machine
Q:Work done in water pumping?
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).
Q:Timing Belts and Water Pump?
no your water pump should be fine if the belt wasnt spinning the water pump then nothing was moving to break or whatever the way you can tell if your water pump is bad is it will leak green antifreez out of the front of the motor and you will see green puddle on the ground but if its not leaking then its good
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
In the picture, to the right is the entrance, the left is the exit, the water pump inlet channel section area generally will be bigger than the export.
Q:need a new water pump?
It is very easy and straightforward. The hardest part is the fan clutch unless you have the proper tools. You have that part covered. DO NOT USE ANY SILICONE SEALER!!!!! Be sure all traces of old gasket are removed and install the new gasket dry. Use an anaerobic sealer on the wet bolts. Those are the ones that are through drilled into the water passages. Clean off the threads then use a light coat of sealer. I use either Permatex (brown stuff in the tube) or pipe joint dope. Now is also a great time to flush the system, replace thermostat, and drive belt(s).
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
60Hz pump and 50Hz pump itself is not much difference, just that the motor speed, the rated speed is 3600 rpm, 1200 rpm, 1800 rpm, the latter is generally 3000, 1500, 1000 etc.. If it is to use the same pump, the difference is that the 60Hz motor pump flow is 50Hz, motor water pump flow of 1.2 times, the lift is 1.2*1.2=1.44 times, power is 1.2*1.2*1.2=1.728 times. So in the actual manufacture, especially some relatively large flow lift pumps, pump motor using 60Hz to use 50Hz thicker than the spindle motor of the pump impeller, the difference between the two, in addition to empty size shaft is different, what basically no difference. As for the data of package angle, the water conservancy models of different factories are different, but I don't know whether there is any difference between them. Most of them make no difference. However, if you want to use the 60Hz pump to achieve the same flow rate as the 50Hz pump, the impeller of the former should be cut to 0.833 times the size of the latter.
Q:Tightening bolts on volvo water pump...?
the pump is held on with 6mm x 100 thread pitch nuts and bolts. the best tool to use will be a 1/4 inch drive ratchet and short extension with a 10 mm deep socket [6 point] these bolts are 12-15 ft bs. of torque if you snug bolts down evenly and use only moderate pressure as a final tighten you should be alright. after srarting all bolts let pump relax so the top seal is not crushed
