Vertical Multistage Fire Pump

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.

Q: I have a 1997 Saturn SL2 and I was wondering how much would it be to replace the water pump? Would it be less expensive if I took it to a neighborhood mechanic instead a more popular one like Goodyear or something? Thanks for looking.: i just replaced my water pump on my jeep, the whole water pump kit was about $59.99 with lifetime warranty, most mechanics charge alot to do it, i did it myself, you just need a water pump, gasket, coolant draining pan, bottle of coolant and the procedure is pretty easy

Q: i wanna use a water pump to pump air...but im afraid that it might burn or sth....: Probably not...give it a try.

Q: We are leasing land from a friend to put horses on. We're in the process of building a barn. We don't want to run water out there because its too much trouble for the meter and everything, but someone said to get a water pump and pump the water from the pond and filter it and use it. I have no idea what all we need or what kind of pump to get. Helpp!: There are many choices and lots of problems. You probably can use a small system with garden hose even depending on how much water you need. There are a lot of variables to define. How much water ie gallons per day? How far do you have to pump it? Is it uphill or downhill? What quality is the pond water? Filtering is a little harder but you should find in line systems or something on the web once you determine the flow rate etc. That may determine the rate you can pump at ie the filter capacity. Do you have electric? If not you need a gas setup pump or generator. What kind of storage tank are you going to pump water into? Sounds like your filter will be the big thing. If you pump 100 gal thats about two bathtubs full. If you pump that in 100 minutes that is 1 gallon per minute. Thats small. So if you can find a filter to do say 1 to 10 gpm and that type pump you can do two bathtubs or more in two hours or so. If you go to 10 gpm thats about the max for a garden hose. Thats more what you would want to spray from the system. Your filter is the key. How clean is the water? Then you need a pump for the flow rate and pressure that can go through the filter. City meter sounds easier now doesnt it?

Q: What are the export pumps packed in cartons?: Our imported pumps are covered with plastic tape and bolted to wooden containers. The wooden box is nailed down.Naturally, the larger pump uses the larger container accordingly.Suggest exports, as sure as imports, OK.

Q: I have a water leak, and not from the radiator. It is on the side of the motor where the timing belt is. Could it be the water pump? or possibly freeze plugs? If so where are these?: Its located under the timing belt cover. Time to replace both the belt and water pump while you or your technician are in there. $500 at dealers typically.

Q: I just replaced my submersable well water pump, the wire that connects the pump, the d switch, and the water tank. Everything was installed correctly and with the help of a licensed plumber. While the D switch is closed (providing power to the pump) the pump will run for about 5 seconds then shut off for about one minute. It will continue this process until the system attains proper pressure and the D switch will open, shutting off power to the pump. The pump is brand new. Why, when power is being supplied does the pump cut on and off? We have tested the current at the well head and it shows that 230 is being supplied the whole time that the D switch is closed, which is correct.: Your problem is with pressure. The air tank needs to be 2 -4 lbs below that of the setting of the D switch. I had to change my air-tank a couple of weeks back, and I had the same problem. EDIT: the current drawn should be about 24 Amps and the line voltage is 230v with resitance at 100K ohm. for the coils. Cure: Using a good tire air valve checker, make sure the air tank is about 25- 28 lbs. Turn off all the faucets or the main valve feeding the house or garden lines. Give power to the pump. Turn the D valve nut (the one with the spring) **up** one half turn. Turn on the valve and let the water run and listen for the pump working. It should run for no more than 2 minutes. (there is a thermal cut-off in the pump that saves you blowing the pump up). When the thermal cut-off disconnects the power, don't worry, all is well. It is trial and error with the setting and is a pain in the butt, but you will get the setting right, I assure you. Remember, turn up 1/2 turn at a time... Best of luck. XX

Q: How much should it cost to have the water pump replaced in a 1994 Dodge Ram truck?: 50-80 bucks for a water pump + gasket. Thats all, unless you're wanting to take it to a shop or dealership. Then it'll be anywhere from 400-800 depending on the shop.

Q: I have a 2002 honda civic with 85k miles the dealer says the timing belt should be replaced. But with the water pump timing belt tensioner also have to be replaced???: It relies upon on the vehicle, in diverse fashions, like maximum mitsubishis, you could desire to take the timing belt off to alter the water pump. So then that is an included operation and there is not any extra suitable value linked with the exertions to do the timing belt, it merely makes it a handy, value saving time to do it. there is not any rule approximately changing water pumps and timing belts at the same time. If that is not an included operation there is not any element to do them on a similar time. The timing belt is physically powerful preventative upkeep yet there is not any might desire to alter the water pump previously that is showing signs and indicators, and there are a brilliant style of them, that that is going to die.

Q: my water is frozen from pump to faucets,do i thaw from pump to faucet ,or faucet to pump?: open faucet nearest pump, use hair dryer on line from faucet to pump. Of course you need better insulation, but you can leave a faucet drip to help keep the line from freezing up until then.

Q: 90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?: Imports, such as Schneider, press: plastic case press 250A, contactor select 115 of 2, 95 of 1 can.Domestic recommendations: Press: plastic case press 250A, contactor 160, 2, 115 of the 1 can.
