General Description

LC series vertical long-shaft pump is a newly developed product with both homeland and overseas advanced experience in design and manufacture. It is used to deliver clear water, sewage with certain solid particles (such as iron scrap, sand, coal powder etc.) and industry waste water and seawater with corrosive. The temperature of liquid can not be above 80℃. It is widely used in original water works, waste water factory, metallurgy and steel industry (especially suitable for delivering oxygenation iron sheet water in swirl pool), power station,mine, civil project and farmland etc.

Structure
The type LC vertical long-shaft pump is installed with single foundation, its inlet is vertical downward and outlet is horizontal. The pump and the motor are directly connected. The rotation of pump rotor is counter clockwise looking from the motor to the pump; the main features are as following
1. It is fine designed with hydraulic design software. It makes impeller and other wearing parts have a long life because of anti-abrasive impeller and Diffusor. The pump is not only reliable, safe, steady but also saving energy.
2. There is filter in pump inlet with proper hole, this can not only prevent impurity entering pump to damage pump but also decrease inlet loss and increase pump efficiency.
3. Impeller adopts balance hole to balance axial force. There is replaceable seal ring in front and back cover board of impeller to protect impeller and pump.
4. Pump middle shaft, water column and guard pipe are multi-burl, middle shaft uses technology of sleeve coupling. Water pipe can be more or less for different inundated depth according to user’s requirement. Impeller and Diffuser are multi-stage for different head.
5. Water pipe is connected by flange with guide bearing in its middle. Pump guide bearing adopts ethane or THORDON bearing, it can also adopt rubber (when the temperature of liquid is over 55℃).Shaft is protected by guard column, the guide bearing should be supplied with exterior cooling lubricating water, while delivering sewage.
6. The remaining axial force of pump and the weight of rotor parts are borne by thrust bearing in motor seat or motor with thrust bearing. The thrust bearing is lubricated by dilute oil and cooled with exterior water. The thrust bearing can have element for monitoring temperature.
7. Pump shaft seal adopts packing seal, there is replaceable shaft sleeve in shaft seal and guide bearing to protect shaft and it is convenient to adjust axial location of impeller by nut in bearing parts upper end or pump coupling.
8. Pump can be equipped with controller which can automatically start and stop pump according to liquid level, give an alarm for over loading and control many pumps in long-distance. There is automatic exhaust system for pump with diameter over 500mm.

Q:I'm having problems with my washer not filling, instead water is going directly out the drain. i want to see if something could be stuck in the pump. I have never looked at one before so I am not exactly sure what to look for. If you'd like you can see my previous post regarding this issue iv'e been dealing with all day. I dont have the money to hire a professional so I am trying like heck to figure it out myself.Thanks
Sounds like the pump is operating during the fill cycle. if there is something clogging the pump, you wouldn't be losing water, it would never drain.
Q:how do I know my water pump failed. 98 mustang V6 started to leak coolant from the front lower part of the the engine. How do I know for sure my pump is bad? Did refill and kept on leaking as I manage to get home. Little help please!
Locate the leak. If it is directly below the pump, you are right. There are many other points on the far that will leak coolant also.
Q:In the past 9 months, Ive went through 6 or 7 gallons of antifreeze, I was told this was not normal. Ive had my coolant tank flushed 4 times this year, only to be told thats not normal and one lasts a few years. Now that its colder outside my car takes a while to run hot of course, but during the summer it ran hot in about 15 minutes tops. I got a brand new coolant tank before I got another flush because I did have a leak, but that did not combat the problem. I had my radiator looked at and I was told thats fine. So im thinking either a cracked head gasket or a bad water pump...help please. im getting tired of putting money into this car only for the same stuff to keep happening.
have it pressure tested for leaks to begin with,then have head gasket checked by checking for bubbles in radiator filler while idleing
Q:Had my car in to the shop this morning, it's a 2000 Ford Escort ZX2. The water pump and radiator need to be replaced, and they said they can do it for $380. Is this a reasonable price? Also, if I don't get them fixed right away, am I risking a lot of permanent damage to the engine?
that's not a bad price at all, considering the radiator is $150 or so by itself, and $50 or $60 for the water pump. So over $200 worth of parts, leaving roughly $180 for labor, not bad at all. Possible engine damage, yeah, lots of it. Blown head gasket is the most likely, a $500 repair.
Q:It has a small leak that started this day and it has 60000 miles on it , also new or rebuilt . What is the appr. cost tohave a shop do it ?
Its not hard at all but you do have to have that special tool which is around $60.00. But if you are crafty you can make your own, easily. Don't go for a rebuilt one get a new own. Make sure that it is level before putting it on. We put one on my Z71 and found out it was slightly warped and had to go exchange it after trying to get it tight enough and never could.
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:My car is over heating.the hose that goes to the thermostat is swollen.i wanted to open the radiator to release the pressure but it was too hot ,and too much pressure. is this a sign that the water pump is good?
First let me say the GOOD LORD was watching over you. You NEVER NEVER NEVER open a radiator cap when it is hot. Had a friend do that and he now has scars on his chest where the water sculled him. Yes it is working. What you need to do is change the thermostat. But please wait until the engine is cool to the touch.
Q:The at is a 2003 Toyota celica. And how much would it cost to get the water pump and timing belt replaced?
It’s useless to try and get an estimate for the cost of parts and labor for repairs via Yahoo Answers. In a lot of cases we have no idea of what country you’re in, let alone city, state, province or township. Even knowing where you live is of little use as prices for parts and labor can vary wildly within the same area. If you understand the problem and just need parts you can Google for the best prices for parts. Your best solution for getting an estimate of repair costs is by contacting an independent auto repair shop in your area. Don’t go with any of the franchise or chain type auto repair places as they frequently use poorly trained help and many have no mechanical training at all, and dealers have to charge more to cover their high overhead. It’s really best (when possible) to get a personal referral from someone you trust to a local independent shop.
Q:I'm looking for a high pressure water pump ,preferably submersible, between 80-100 psi.
go you five and six show room only prospects of high pressure of toll pump or submersible menu check if you like buy no like no buy
Q:I am replacing the water pump and want to know exactly where the two o-rings go
There are several rubber seals on a water pump. The biggest irregular shaped seal is obviously for the main portion of the pump (this can not be misinterpreted for something else). The next in size is the o-ring for the thermostat. And 2 additional O-rings (one smaller than the other) are for the return pipes. While removing/pulling out the pump, take care that the pipes do not get pulled outward by the pump. And when putting in the pump just gingerly align the pipes to the holes in the pump and you are good to go.
