SQJ Series submersible pumps widely used in farmland irrigation, spray irrigation and water-use, industrial and civil

buildings, also the drainage system to level hills, mountains of diversion, in the low-lying areas dunes, urban and rural

mining supply, drainage and other water conservancy facilities. Its characteristics are the electrical, water pumps and

assembled into a simple structure, the installation of the demolition of convenience, small footprint, the use of simple maintenance, safe reliable operation, no water pollution and so on.

3. Use conditions:

(1). 380 V bias voltage does not exceed + -5% and 50 HZ frequency, and the deviation is not more than + -1% of the

three-phase power supply.

(2). Electrical cavity must fill water.

(3). The first-class pump impeller should at least go into the dynamic water level 2 m below surface. Static pump unit

immersed under water shall not be greater than 70 m.

(7). Water PH 6.5-8.5.

(8). The hydrogen sulfide in water content is not more than 1.5 mg / L.

(9). Water should ensure continued operation of the pump needs.

4.Structure feature:

(1). pump: The pump is installed on the upper part of the pump units.It's centrifugal and has water lubricated

a. bearing mounted with the motor shaft by a joint.

b. There is a check valve on top of the pump which could prevent rapaid inverse rotation from backword flow.

c. The pump unit should be immersed below the dynamic water lever when in using.

(2). motor: The motor is installed under the pump.

a. It is a water filled in hermatical structure.The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.

b. The motor bearing is water-lubricated.The inner motor contains clean water to cool the water body and the bearing.

c. The rubber diaphgram adjusts the pressure change caused when temperature rises.

d. There is a sand resistance system in the upper part of the motor.

Q: We bought a plot of land and me and my father found a deactivated water well in there. We checked and it's 328 feet deep and is still full of water.How would i go about setting up a pump on it?: have that water tested before you do anything.

Q: okay i just put a new camshaft in my truck and before my water pump seemed to work but it leaked a little bit but my truck never got hot well i drove it a little bit after puting in the new camshaft and the top radiator hose and heater hose was warm but the bottom radiator hose was cold so i think my water pump went out but not to sure thanks to any answers: when your water pump goes out, either it will leak from the weep holes which are the holes drilled in the pump by the manufacturer or around the pulley. If that is happening then its your pump. The other thing to check would be your thermostat, check this by turning your truck on and leaving the lid of the radiator. check the temperature of the water in the radiator with your finger if it warms up in ten minutes then its not your thermostat, if the water level goes down ( like lack of water) then its the pump.

Q: We usually wait 4 - 5 minutes for hot water in our master bath. I've been looking into ricirculation pump systems. This would have to be a retro-fit system since some of the lines run through concrete slab making adding a return loop on the line non-feasible. I have found some people comment on simply using a by-pass valve system without a pump (ie. Hot Water Lobster). We do have hard water which I've also read that can present a problem with pumps dieing quite quickly. While I'd like it, I don't need 1 second hot water, but I can't stand wasting gallons waiting for 4-5 minutes. A reasonable 15-30 second wait would be a huge improvement. Has anyone had reasonable success with the bypass valve without the pump or should I plan on getting the pump too? Thanks in advance!: Without a basement, you're only moving water from the first to second floor? I'm guessing it's a large home and the baths are somewhat remote from the water heater. You should consider the pump, but perhaps a second water heater. Do you have a closet you could put a small electric unit in? I don't think that a 4-5 gallon under counter unit will do it. Good luck.

Q: I was wondering if water pumps make any noise when they are submersed? Also, my pond is quite small and I don't want to scare my fish with a noisy pump. Thank you!: majority of the pond pumps you get to day are extreamly quiet and wont bother the fish or you at all

Q: After reaching a height of 50 feet , there should be enough pressure to hose around 20 to 30 feet of water from it for curing concrete structure ex: columns, slab area etc. How many inches ( diameter ) of rubber hose is required to plug the water pump for pumping water ?: hp list of water pumps

Q: explain the operation of a water pump....?: There are a number of different types of water pumps that operate according to different principles. For lots of information, including pictures and diagrams, do an internet search on water pump.

Q: 2005 pontiac grand prix 3.8 v6There is a scratching type of noise when i start the car. Looked under the hood and it seemed to be coming from the serpentine belt.Took the belt off and and checked the pulleys for any play and turned out the water pump pulley wobbles back and forth too much. Replaced the belt with a new one and want to replace the pulley. It does not seem to have a loose screw so i'm wondering if i can take the pulley itself off and replace it, or would i have to replace the pump too? Still makes the noise with new belt and you can see the pulley wobble a bit when the car is running.: you have to replace the pump ! it,s not the pulley that,s wobbling, it,s the bearing in the water pump that,s bad and you can,t replace the bearing !

Q: does aquarium pump go in water?: NO the air stone is connected by airline tubing. The airstone should be in the water, the pump out.

Q: I would like to change the water pump myself but do not have a repair manual.: Im guessing you have the 3.4 liter engine. You will need to remove the pulley bolts first 10mm, then pull off the pulley and the belt. there should be a few 10mm bolts holding the water pump on, remove them and scrape off the old gasket with a scraper and then clean the rest up with some fine grit sandpaper. Don't scrub one area for too long because the surface is soft aluminum. you will need to spray some brake clean on a rag and clean up the surface so there is no coolant or dirt on it. Now put the new gasket on the new pump and put a thin layer of silicone on the side of the gasket that is going to mate with the engine block. Do not put silicone on both sides of the gasket. Make sure to note wich way you took the old pump out because it only goes in one way and torque down the bolts so they are snug, don't overtorque or you will strip the aluminum. Now you will need a half inch rachet to pull back the belt tensioner to be able to put the belt back on. There should be a picture of how the belt is routed somewhere under the hood. Don't forget to buy Dexcool (Red Antifreeze) Make sure you don't mix it with the green antifreeze. Good Luck

Q: will a water pump that has gone out in a car make water come out the radiater: yes it,s overheating the water pump needs to pump the water away from where the engine needs cooling the most or if it stays there it will heat quickly and boil and create bubbles like when your cooking water in a pot this causes the pressure to increase and forces the water run out the radiator by now you could also have a blown head gasket and that can also force water out the radiator,are the water and oil showing any major pollution as in water in the oil or vice verse.
