1.Introduction:

CDL/CDLF high pressure water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

2.Applications:

· Urban water supply and pressure boosting

· Industrial circulating system and processing system

· Water supply for boiler, condensing system, high-rise building or fire fighting system.

· Water treatment and RO system

3.Electric motor:

· TEFC motor,

· 50HZ or 60HZ 220V or 380V

Q: A direct type pump model with the coupling type, what is the difference?: The water pump type is directly connected with the motor, and the motor shaft and the pump are coaxial;Pump motor and pump shaft is separate, with the coupling power transmission.

Q: I need a 12v water pump capable of at least 40psi. The only website that i found is one where you have to order a minimum of 100.: You can buy pressure pumps from HIMIN SOLAR CO.,LTD, SUN MOON MANSION, SOLAR VALLEY ROAD, ECONOMIC DEVELOPMENT ZONE, DEZHOU CITY, SHANDONG,CHINA.

Q: What are the export pumps packed in cartons?: Upstairs said the basic right, but only limited to the domestic, export also put the pump's wooden case (frame) into the carton.

Q: 300M head of 11 stage centrifugal pump with 22KW motor, empty (not water) current of 13A, the water into the pump, current up to 44A, open the outlet valve of the current rising to 100A, immediately shut the gate current is up to 170A, the motor stop. Without any problems, not on the impeller pump shaft is not clean the shell the balance sheet, no wear, bearing normal.: The description of the problem is very clear. Most of this kind of circumstance is overload, is also the outlet pressure is very low, the flow is greater than the rated value caused by the resistance can be adjusted by increasing exports or close the outlet valve, reducing the flow resistance increased by less than or equal to the rated flow. Lift is not an influencing factor.

Q: I just had my water pump/timing belt replaced and oil change. When the pump failed, white smoke was coming out, which I figured out to be coolant from the smell. Now there is smoke coming out from under the engine, which I believe to smell like oil. Also, the temperature gauge goes up to the halfway point when I am at a stoplight or idling. The highest I have ever seen it is at 1/3.I had my car serviced by the dealership and I asked them. The man said its burning oil residue from the oil change and that it will burn away in a few days. Is this true? I have had my car worked on and oil changed for the past year at this dealership and have never had any smoke or other problems. What else could be going on? Worse case scenarios. Thanks everyone.: Almost every time i have seen this in my 35 years of exp.its turned out to be a cracked block or head.

Q: I have an 1982 El Camino 305 small block and am having troubles with determining if it is the gasket or the pump. I can't quite locate a leak, but it seems to centralize from the water pump and drip down the hose to the radiator. After my engine gets hot, which mind you my temp light has never turned on, and I shut of my car steam rolls out from behind my pump. I think it is the pump and please be it so. (Easier and cheaper fix. Replacement with a inexpensive part XP.): There should be a weep hole on your water pump from where the antifreeze will be leaking if the seal is gone. Clean it up real good and try to see if that is where it is leaking from. Also check the thermostat gasket. If I remember correctly it is located above and just behind the water pump on a 305.

Q: I have a Honda Accord, and last week I replaced the Radiotor, due to a leak. This week the Water pump broke, it was making a ver loud noise and major leak, when I opened the rad, basically all the fluid was drained.Do you think the two are related? or do you think when the Rad was replaced it was not done properly which caused the water pump to break?Thanks.: Tough question but lemme give it a shot. The radiator would probably not have cause the water pump issue unless there was a very large obstruction that took out the impeller of the pump. If that were the case then it would have been possibly related. Otherwise, I would not suspect that. The radiator leak fix might have suddenly ensured that there was enough water in the system to keep the water line above the pump. If you ran the system dry, the pump could have given out due to running dry. To really answer the question, you might need to know how the pump failed. Tough one though. I am trying to think exactly how other than mentioned above, the repair could have taken out your water pump and I am stumped. When I have had issues with cooling and have abused the system by overheating, I have had to replace multiple components in the past. Simply due to heat abuse; never good on an engine or components.

Q: I would like to change the water pump myself but do not have a repair manual.: 2000 Chevy Impala Water Pump

Q: can you replace a water pump gasket without replacing the whole water pump?: Of course you can they are two seperate items. Obviously you have to remove the pump to remove the gasket. Just make sure that the pump is in good condition, and use a little gasket silicone on the gasket. Dont overdo it with the silicone, just a thin smear on each side. Also make sure all traces of the old gasket are carefully removed from the pump and the block face. Any dirt or old gasket remnants left will cause a leak, so double check before replacing the pump to its position. Cheers

Q: Could it make coolant quot;Boilquot;? Ive heard myc ar's behavior is Normal, and most likely just heavy condenstaion as it DOES go away, also the behavior of the coolant and the tank.. but i DO know the Water Pump is quot;Weeping,or quot;Seeping,so i wonder what interaction that would have ont he Cooling side of the motor; what effects can it produce? What would i notice?My 1991 Calais 2.5L quot;Iron Duke,: Steam coming from your headlight on a rainy night is NORMAL, since the halogen bulb makes a lot of heat. This turns the water into water vapor, (steam) as it attempts to dry out. If you don't physically hear the bearings in your water pump, or watch colored fluid drip out from under your engine, then your water pump is JUST FINE!!! STOP WORRYING! I answered one of your questions the other day. If you take my advice, your engine will run at it's best. For extra protection, drain and flush your cooling system out, and use Mercedes coolant. Dex-cool has been proved to be a potentially bad coolant. READ the dexcool litigation websites. Mercedes coolant, which is YELLOW in color, will last for 150,000 miles, and is a time tested WINNER!!! Use ONLY top tier fuels (read about this on web) and use ONLY synthetic oil, like Mobil One. CLEAN your idle air control valve and throttle plate. AND STOP WORRYING!
