Product Overview of D Series Horizontal Multistage Centrifugal Pump

This series of pumps use national energy-saving hydraulic model, developed and updated constantly by our factory, with the advantage of high efficiency, wide range of performance, safety and smooth operation, low noise, easy installation and maintenance, long life, and its technology level is in the domestic leading position, product performance is reliable.

Features of D Series Horizontal Multistage Centrifugal Pump

This series pump is a horizontal, single suction, multi stage centrifugal pump section, the suction is in horizontal direction, and outlet is vertical upward. Water suction, middle, discharge section, bearing housing and pump body are bolted into one strain, and select stages according to the pump head.
2. Rotor includes shaft, impeller, shaft sleeve, balance disk, and other parts. Axis parts are connected through the flat keys and the shaft nuts. The rotor is supported by the rotor bearings or sliding bearings in both ends, the bearing does not bear axial force, axial force is balanced by the balance disc. Bearings lubricated with grease, sliding bearings lubricated with light oil, and oil ring lubrication, and cooled by circulating water.
3. Shaft seal in the form of two kinds, mechanical seals and packing seal. When use packing seal, the packing ring should be placed at the right location, the tightness of packing must be appropriate to the liquid oozing drop by drop. Various sealing elements is in a sealed chamber, the chamber must be filled with some water, as water seal, water cooled or water lubrication. At the seal there is replacable sleeve, to protect the shaft.
4. From the motor direction, the pump is clockwise rotation.

FAQ

Q: Are CNBM pumps available in DIY stores?

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

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:water pump leaking antifreeze?
Once the water pump starts leaking, you can never be sure just how fast it will deteriorate further. But sometimes, they go from a little leak to a big leak real fast. So I would get it to the shop ASAP. Bring a couple of jugs of water with you in the car if you can get along by stopping every 15 minutes and refilling the radiator after it cools down. But if it starts dumping coolant out like Niagara Falls under the car, you will have to have it towed to the shop.
Q:on changing a '86 volvo 240 water pump?
Two questions 1) Did you buy a new gasket? 2) Did you let the sealant set long enough? If you answered yes to both of these than the only thing left is to make sure you have the right type of sealant. Is it the waterproof stuff for waterpumps? You mentioned the stuff was red, it's been a couple of years since I changed a waterpump but I believe it was the BLUE stuff that I needed. But I could be wrong. Take it apart. Make sure it's clean (you can use a wire brush but I find a paint scraper works better) and apply the new gasket to the new water pump then but the whole thing back on the engine. Star pattern tightening the bolts. Test it without putting the clutch fan (I think this still has one) back on just to see if it's leaking. Hope that helps.
Q:Small 12v Water Pump for Air Mister...........................................................................?
The ac converters are 12V rectifiers so just use the pump (wire to a battery) without the converter or check with motor home repair place
Q:Water pump for distillation unit?
The only thing you might need a pump for is if you are distilling/refluxing something and it is not all condensing before it reaches the end/top of the tube, resulting in vapor escaping. In that case you would use a bucket of ice water with a submersible pump.
Q:Replace Water pump, big noise came out, then jump time and engine died?
You have a good case for small claims court, but you'll have to prove the facts in court, not here on yahoo. 1) Prove that the first shop changed your water pump. (I think there's a good chance that mechanic did, indeed, mess up the timing.) 2) Get something in writing from any subsequent, licensed mechanic who thinks the timing was changed. At 100,000 miles, there's a fair chance your timing chain could have been old, needing replacement, but if the first guy replaced the water pump, that seems the likeliest culprit. Worse, I hope you didn't ruin the motor. Sometimes when your motor is out of time, you can bend a valve or put a hole in the piston. Better get your motor checked by someone who knows what they're doing then consider your options- small claims or the first mechanic's insurance company. If you talk to the insurance company, you should have a lawyer do the talking. Good luck!!
Q:my expedition keeps over heating. i put in a new thermostat,water pump allready. help please?
Check the compression,could be a broken ring.
Q:how to replace water pump 97 pontiac bonneville?

Q:How to find in a web how water pump works & its cross sections?
A pump is a device used to move liquids, or slurries. A pump moves liquids from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system). A gas pump is generally called a compressor, except in very low pressure-rise applications, such as in heating, ventilating, and air-conditioning, the equipment is known as fans or blowers.
Q:how many consequence hours can I leave my water pump working?
You are correct Amps x Volts = watts and since there are about 750 watts per Hp then you have a 2/3 Hp motor. Water pumps can be either submerged in the well bore hole or located top side. A top side well pump relies on the air around it to cool the motor. THe motor may not be rated for continuous duty (see name plate on motor) and may only be rated for a limited amount of time it can be run before it needs a cool down period. (Typically motors are rated for continuous duty) Submersible well pumps are located under water in th well and use the water in contact with the motor housing to cool them. Cooling is thus related to the water flow around the motor and the availability of water. Normal well pump usage for a home is for brief periods when water is actually being used and to maintain system pressure. So unless you are constantly watering your lawn your pump should cycle on and off as necessary. Continuous running is a sign that there is a problem such as a leak, worn pump not achieving proper pressure, or pressure switch setting or similar issue not allowing proper shutdown. If you have a submersible well pump it will be very difficult to tell when it is running unless you can hear the motor contactor open and close or have an indicator light. A properly operating water system will pressurize an accumulator storage tank (water pumped into a tank which contains an air bladder that can be compressed). Once the tank is pressurized the pump shuts off and stays off until the pressure in the tank drops. Pressure drops when you use water or if the water leaks back into the well. At which time the pump runs again and tops off the tank. So in a properly operating system shutting off the well at night won't save you much because the pump should not be running. However if you have a leak and the pump is running a lot you can secure the power to the pump at night until you can get the system repaired
Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
