Model GDL multi-stage pipeline centrifugal pump is a new generation product designed and made by our company on the basis of the excellent pump types both domestic and overseas and combining the requirements of use.This pump uses a vertical,sectional and stainless steel casing structure to have both inlet and outlet on a same level,of a same aperture and capable of being mounted in a pipeline just as a valve and collects the merits of the high pressure of a multi-stage pump,a less land area of a vertical pump and convenient installation of a pipeline pump and,due to the excellent hydraulic model it adopts,also features a high efficiency,energy-saving,stable running ect.,in addition,because of the wearable mechanical seal it uses as the shaftseal, it has no leak and a long duration of use.To provide a better statisfaction to the requirements of users,this Co.also develops model GDLS the outlet of which is located on the upper part and both inlet and outlet can be mounted in different opposite positions(0° 90° 180° ),leaving an extremely convenient use.
Mainly used for the circulation and boost of both cold and hot pure waters in a high pressure moving system,water supply with pumps in parallel in a high building,the water supply and cooling water system of fire-fighting and boilers and the transporting of various rinsing liquids.

Q: my sump pump keeps filling with sewer water. i cant figure out why or where it could be coming from. and the smell is awful.: The only way you can have actual sewer water in your sump pump is if there is a broken pipe that is leading to the sewer and broke. It would have to penetrate and saturate the ground, then go all the way into the soil under the foundation and enter your drainage system under the basement floor. It then would run back to the pit containing your sump pump which would pump it back up through the pipe and start it all over again. If you have a septic tank the same pipe could be leaking, the tank might have a crack in it, or if you have had a massive amount of rain the field might be swamped and the water is following the pipe back into the house. If on a municipal sewer the municipality is generally responsible from the house to the street and you are responsible from the foundation back into the house. If it is septic system, you are completely responsible for all repairs. First thing to do is decide which system you have and call them if it is sewer system, call a plumber if you are on septic.

Q: As I wrote last night, I have a Isuzu Rodeo V6 3.2L 4X4. I guess I misunderstood my husband. I talked to him this morning and he said that it did overheat but the gauges on the inside of the car wasn't showing that it was overheating. It wasn't spewing coolant but the coolant that was just filled up a couple of weeks ago is empty. Does anyone know what the problem is?: please do not drive this. it seems you have two problems: your gauge and/or sending unit is not working . and now that you have developed a leak you are overheating with no indication. Please you will severely damage your engine dont drive but if you must install a generic mechanical temerature sensor so you may at least monitor the temperatur. it shouldnt cost more than 20 bucks. and almost anyone that knows about cars can install in 10 min

Q: i installed a new pump don't know how to increase water pressure and to what what pressure it should be set: This is very simple i would sugest the pressure to be set betwene 60 to 70 NO MORE THAN 70. 1. turn off power to pump (ether the circut breaker or a switch near the pressure switch) you dont want to weld the wrench to the switch. 2. remove the cover to the pressure switch its self (usly one #2 phillips screw) 3. now you will see 4 wires under some sloted screws nearest to the front of the switch, behint that is 1 or 2 bolts with a spring and a nut. 4. if you see 2 bolts you will want to turn the nut on the larger one to the right. you will want to tighten it about 1 to 2 full turns. (the same goes if there is only one bolt also) 5. now open the valve that is on the tank untill you here the switch click. then close the valve. 6. turn the power back on tio the pump and watch the pressure gauge on the tank. i DO NOT RECOMEND MORE THAN 70PSI. 7. if it goes over the pressure you want repete steps above exept loosen the nut in about 1/4 to 1/2 turns untill you reach the desired pressure 8. if it does not reach your desired pressure then you do the same thing exept tighten the nut in 1/4 to 1/2 turns untill you attain your desired pressure. 9. when the pressure is reached, replace cover so you dont risk rusting the contacts. if you need more help feel free to email me. and i will assist you in any way that i can.

Q: how to replace water pump 97 pontiac bonneville?: It depends on which engine you have, with or without a supercharger. The non-supercharged engine is a piece of cake. the supercharged one is a bit of a pain to get at the water pump. On the non-supercharged engine, all you need to do is remove the serpentine belt, the water pump pulley and the bolts that hold the water pump to the front cover. I have detailed instructions if you send me your email address I can give them to you. They are from GM Service Information website. I can't give you the link to the website because I have to enter a password to enter the site through work.

Q: its a honda accord 1991 Lx my car started overheating only when i stop when i go it doesnt overheat what should i check like the water pump: Pull it out of the car and look at it. But since your water pump is most likely driven by the timing belt, that's a hell of a job. My guess is you probably need your timing belt replaced anyways though.

Q: and how do I get it to work 24 hours a day?and on the pump there is written: 2 A, and on another part: 220-240 Vdoes that mean its wattage is 440-480Watt?: 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: Why such a difference in price. Is the GM worth 4 times the NAPA brand. Both are new for a 2003 Buick ParkAve Ultra with 95k miles. 1st time we're replacing the water pump.: I would go with the NAPA one, the GM one that is on the car now did not last forever either, I have had very good luck with after market water pumps for GM vehicles. 4 hours seems a little steep though......Good luck

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.: Yes they are related. First why did you replace the radiator if their was a hole in it it could have drained out most of the fluid and burned up the pump.

Q: I replaced the water pump on my 350 chevy small block with a new water pump and the thing is leaking out of the lower bolt hole on the passenger side. I was told to remove the bolt and coat it with permatex hi tack gasket sealer and reinstall it Any how I'm wondering why there would be a leak there in the first place, any ideas?: Remove the new pump and gasket. Reclean the steel surface and remove any pieces of the old gasket that might still be attached. That surface needs to be perfect. Apply the recommended sealer after this is done . Either a sealer or anti-sieze compound should be added to the threads. Recheck surface of new pump for any flaws and reinstall. Bolt in a criss -cross pattern and tighten equally , partially tight first and then all of them fully tight.

Q: I have a water pump that works with 12V and 2 amps.I was thinking to get a potentiometer to be able to slow down the speed.Is this the best way to do it? What wattage should it have, so it doesn't burn out, and what should be the maximum resistance, to be able to stop the pump completely?And OKorder or product link would be great!Thanks!: A more efficient way would be to use a PWM controller which wastes less energy. Luckily these are available as modules now for motor speed control, so are plug and play with a variable control knob on the front. Just make sure you pick one suitable for your voltage range.
