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:how do i replace water pump for 1993 oldsmobile royale 88?
disconnect battery, drain the radiator of coolant, move it out of the way, then remove the fan shroud that has a top section and a bottom section, once you have that out of the way, remove the upper and lower radiator hoses, the heater hoses that connect to the water pump too, now remove the fan from the water pump you might have either ac, alternator or power steering in the way, and have other bolts. but basically after you have all the rest of the engine removed it is easy to get the water pump off. clean all new surface area's where gaskets touch , use indian head gasket sealer, its the best kind, when you put the new water pump on the engine make sure all the old gaskets are removed and wire brush the water pump housing, use gasket sealer, let it dry ,then put all the hoses back on, the power steering, alternator etc, all back in place, fill up the radiator, let it get to 190% temp, and make sure the thermostat opens, then you know everythings working,
Q:About how to calculate the pump installation height?
Best to find water pump manufacturers, their own bad count. Sometimes is not necessarily correct, which is related to some parameters of the pump itself, with bad cavitation
Q:2004 chevy impala leaking antifreeze behind pulley of water pump?
it's the seal - it needs to get fixed soon
Q:Will an F150 water pump work on an F100?
water pumps are related to engine families. not a weight class. in this era, w/o getting into what family engines share a given pump, i can tell ya, if it physically fit, in all respects, you're good. it wouldn't mount if it wasn't correct. ----------- there is some incorrect info here. like all manufacturers, there are a few different ford blocks of different cubic inch displacements that *do* share the same pump. 289/302 for only one example. that may or may not include a 351. there are 351 Cleavland's, M's, and Windsors.
Q:what water pump is on a 1978 mercruiser 170hp 224cc 3.7 liter?
Something in your description doesn't add up. Mercruiser did not have a motor branded as 170 hp in 1978, only 85-86. The 224s where a Mercury invention, all about the same for around 15 years. Do you you have a ser #, much more accurate identification.
Q:WHAT WATER PUMP SIZE?
Your pump rating will depend on the requirerd flow and so with your pipe size requirement. A goulds submersible pump can deliver heads up to 500 ft.
Q:What are the steps to take out a water pump for a grand am 2004?
You did not say if you have a 4 cylinder or a 6 cylinder. The 6 is really easy so I will assume you have a 4.If equipped with an automatic transmission, remove the exhaust manifold. Refer to Exhaust Manifold Removal in Engine Mechanical - 2.2L (L61). Drain the cooling system. Refer to Cooling System Draining and Filling . Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. Remove the right front tire and wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels. Remove the front fender liner. Refer to Front Fender Liner Replacement in Body Front End. Remove the access plate on the water pump sprocket from the timing cover. Install J 43651 to the water pump sprocket. Use the access plate bolts to secure J 43651 to the engine front cover. Remove the bolts that secure the sprocket to the water pump. Remove the bolt (1) that secures the engine block to the water pump. Remove the bolt (2) that secures the engine front cover to the water pump. Remove the feed pipe that joins the thermostat housing to the water pump. Remove the 2 bolts that secure the water pump to the engine block. Remove the water pump.
Q:My brand new well water pump is acting incorrectly?
I had one doing this similarly. The well was out of water or the pump may be too high in your case. The pump has a thermal cut out that is cutting out because it is protecting itself from over heating. once it cools a bit the thermal resets and it will pump again for a short time till it gets hot again. Perhaps this is your problem it was mine. I had to drill a new well. I assume you know there are 120 volt pumps out there be sure what the old one was. 220 probably would have cooked it by now anyway. Take the cap off and listen for the pump sound if it is out of the water you will be able to hear it if not to deep.
Q:how to convert a deep well pump to shallow well?
Gould Shallow Well Pump
