General Description
Type CRQW submersible sewage pump is newly developed on the basis of the advanced technology from international. Is used for industry and commerce, the living area,urban sewage treatment plant, waterworks,civil air-defense construction,hospital,hotel and so on. They can also be used in public works, explore, country methane, irrigation, deliver water with impurity. The flow-rate range of the delivery water is 7-10000m3/h, lift range is 7-60m,power range is 0.55-315KW, caliber range is φ25-φ700 mm.

Service conditions
* Medium temperature should not above 60℃, Maximum density is 1.3×103kg/m3.
* If the pump without a build-in self-circulation cooling system, its motor should not expose above water more than half.
* Deliver medium’s PH value is between 4 and 10.
* Solid particle passing capacity is 60% of the inlet diameter, the length of the fiber is 5 times to inlet diameter.

Instruction of pump type
Example: 100CRQW100-15-7.5
100 in the front: Pump outlet diameter is 100mm
CR: Company code, means produced by CREDO PUMP
QW: Submersible sewage pump
100 after: Flow capacity 100m3/h
15: Head is 15m
7.5: Motor power is 7.5KW

Structure

*Type CRQW Submersible Sewage Pump adopts particular single blade or double blade; advance the ability for get across feculence. Fiber about 5 times as pump caliber can across.
*Mechanical seal adopt fresh model cemented carbide rot-proof material, and at the same time, we improved on the airproof to the single-ended double-face mechanical seal, let them work in oil chamber for a long period of time.
*The whole structure is compact;, volume is small, little noise and the energy saving result was apparent. The machine needn’t pump room .It can work just dinning into water, so reduce project cost.
*According to need, we can equip safety protection control cupboard to protect the pump, advanced the safety and reliability.
*The float switch can control automatically, do not need specially-assigned person. It’s very convenient.
*According to need, we can equip automatic coupler installation system. So people needn’t get into the drainage ditch.
*Can be used in all the range of lift ,and it won’t overload.
*There are two different install way, fixed type automatic installation system and movable type automatic installation system.

Q:I have a 2001 chevy malibu and need to know how to check if the water pump needs replaced. The engine has been running much hotter than normal and is leaking coolant.
Remove the belt and try to turn it by hand. If it makes a growling noise or you can feel roughness in the bearing, then you should replace the pump. Also, look for any leaks anywhere around the water pump that would suggest it needs replacement. If there's no roughness or leaks at the pump, look elsewhere for a leak. Also check your radiator cap to make sure it's holding the proper pressure. Also check your thermostat to make sure it isn't starting to fail. Check to make sure your radiator fans come on too.
Q:I'm going to be purchasing a laboratory distillation kit here pretty soon, the kit includes everything I need for the setup but the condenser requires a water pump to circulate cold water around the coils. What kind of pump would you recommend for this purpose?
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:4--6 inch deep well pump head? How much per hour out of water?.
General agricultural pump 4-6 inches of lift at about 20 meters, the economic output of water is 140-200 cubic meters per hour
Q:Need to pump water from the stream to my livestock tank on a regular basis.
Yes, lots of them. Sureflo is one. You can find them on the Internet
Q:I'm going on a week long hiking trip and need safe water. What brand and model of water filter/pump should i get? Whats good quality for a low price?
Most distance and light weight hikers carry a Steripen and a paper coffee filter. The Steripen uses U.V. light to sterilize the water, takes about 1 minute for a liter. The paper coffee filter removes any particulate matter in the water if necessary. Depending on the model they cost from $39 to $109. The one I carry is about the size of a large felt tip pen and weighs around 4 oz. It's rechargeable from a usb port, can be charged from my solar charger. The battery is good for 40 or 50 liters between charges.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
Open pump and closed pump, circulating water pump seems to be the full name of the pump, the industrial pump is to provide industrial water. Both open and closed pumps provide cooling water on the side of the machine, just because the requirements for water quality are different. Closed water is desalted water, while open water is recycled water.
Q:Is it cheaper to run an electric water pump or a furnace?
If you live down south in the good old USA, yes it is cheaper money wise. Initial start up costs can be really steep though. I just saw a great system that has solar power along with the geothermal that was $15,000.00 You may want to own the house and I hope it is worth it as it will be awhile before you even out on the costs. This was a 3000 square foot home I saw the system in, so it may be cheaper, BUT, may even be MORE to install because your place may be smaller and what are local regulations ? Good Luck.
Q:I have a 1995 Jeep Grand Cherokee 6 cyl while driving home the other day my check engine light came on ,then I noticed my battery was loosing its' charge ,then I noticed my temperature gauge rising very fast.I stoped to see what the problem was.The vehicle had over heated and the serpentine belt was partially off Iet it cool down then I put water in it and drove it home which was about a quarter of a mile.I noticed no problems with the fan hitting the water pump pully until I put the belt back on .My water pump pulley appears to be off line how do I fix this?
The water pump pulley is bolted to the water pump flange. The flange bolts are sheared off or have worked loose and the pulley/belt combination are no longer turning the water pump. If the flange has come loose from the water pump shaft, it will still be bolted to the water pump pulley. This may have also been caused by a locked up water pump. You can not fix a loose water pump flange or a locked up water pump. A new/rebuilt water pump will have to be installed. Happy Trails!
Q:i replaced the water pump and redid the timing belt. now when i start it, it sounds like one of the cylinder is misfiring and makes a chucking noise. do you have to reconnect everything together to see if thats the problem? the engine worked fine before i replaced my water pump. engine like vibrates at each chucking noise. could it be incorrect timing even when the engine starts fine? or is one of the valves bent which is causing the vibration and noise? i checked teh spark plugs and they are fine could if be bad coils? or is the crankshaft weared out? please help and thanks for you help about my situation.
It should have nothing to do with the water pump. When you replaced the timing belt, you probably re-installed it a few notches/teeth off and the timing is off, and that's why you are getting the misfires. If the timing was WAY off when you re-installed it, there is a slim chance you could have bent some valves, but that's a long shot. You probably just have to re-adjust the timing belt and things will be fine.
Q:Today I see the saying that if your pipe diameter has been selected, then the pipe diameter on the pipe diameter should be smaller. I don't know why
In order to reduce the water outlet resistance of pump outlet.The statement should be: if your pump has been selected, then the outer outlet pipe caliber than the water pump outlet diameter one.
