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.

Performance Range
Capacity: 60-8400m3 /h
Head: 12.5~94.5m

Instruction of pump type
300LC2-50A
300: Outlet diameter is 300mm
LC: Vertical long-shaft pump
2: Impeller numbers (No indication, when only one impeller)
50: Max head is 50m
A: A,B,C separately represents that outer diameter of impeller is changed the first, the second and the third time.

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:water pump replacement..some opinions needed, electrical or not?
Most 1973 era vehicles have a clutch on the fan which stops turning at higher engine rpm which saves horsepower. Your best option is to locate a high capacity water pump for your car or locate a radiator with more passes than the stock radiator. A radiator shop should be able to give you advise on both. Remember, the water pump is belt driven along with several other items on the engine, so replacing the water pump with an electric one might be far more involved and expensive. Plus, the water pump has a seal that must work properly for the engine to retain its cooling fluid. There are aftermarket cooling fans that can be installed in front of or behind the radiator to provide additional air flow, the local auto parts store should have a listing or a company like Summit. Fans can be manually turned on or have a thermo swithch which turns the fan on at a certain temp. These are usually options with the electric fan kits. Good luck.
Q:When the pump is connected in parallel, will the head and flow change?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:2004 Grande Am water pump?
better make sure it,s not the belt squealing and not the pump. usually when a water pump goes out they will leak. i would be checking the belt first.
Q:are high volume water pumps better on a engine or will it cause damage?
High Volume Water Pump
Q:How much does a water pump cost?
I checked online and saw Ford Escort water pump for less than $50. But you can always call local auto parts store like Autozone or Pep Boys to get their cost. Allow up to $100 for water pump. Costs for labor are obviously expensive, too. That's what the costs of $300 that some are saying. Consider $100 for pump and $200 for labor. If they actually think that the water pump would cost $300, they forgot that we're talking about an ESCORT!! Not a Lexus or BMW.
Q:Well water pump quit working.?
If you have galvanized pipes there is always a trace amount of metal (rust) in your water but if you use the water every day it isn't noticeable, as it comes through in such small quantities. It could be that one or more of your pipes froze and cracked, releasing some larger chunks of rust from the walls of the pipes or pressure tank. Run the water steady for a while and see if it clear up. It would be wise to check all of your exposed pipes/tanks for leaks now too because if a pipe or tank cracks it will either be leaking now or shortly in the future. The rust/ice could have also been temporarily blocking the pipes, causing the 0 pressure. If the pump is running with no water, it will run faster and much louder.
Q:Water Pump bearings went bad?
well they do go bad but not very offen.. and really no need to flush if your going to replace it .. nothing to worry over
Q:My brand new well water pump is acting incorrectly?
make sure your pump is wired 220vac. you need to restrict the flow coming out of the discharge of the pump when you are filling tanks/waterlines. Once everything is full and the pump is running at operating pressure it should quit turning off. as said above it is the thermal overload protector in the motor shutting it off. The more GPM you move the more current it pulls, current=heat. restrict it by turning your valve down by half or more.
Q:How do you know if the water pump on a car is bad?
A water pump shows signs of dripping through whats called a weep hole on the underside of the water pump.
Q:Water pump maintenance what should be maintained?
Bearings, seals, impellers - removing dirt
