Vertical Turbine Pump

 

• Name: Vertical Turbine Pump
• Number: nep-001
• Sequence: 2013-03-16
• Manufacturer: Hunan Neptune Pump Co., Ltd
• Origin: China

Application:
The said series pumps are used to transfer clear water, rain water, water in iron sheet pits, sewage and seawater, servicing in power plants, iron and steel works, water supply companies, sewage treatment plants, petroleum and chemical industries mines as well as municipal water supply and drainage projects, farmlands irrigation, flood protection and drain waterlogged farmlands, etc .The temperature of pumped media is 90℃ by special design，the capacity is 30-9000m³/h, the head is 5-220m. it accords with the China town construction industry standard of CJ/T238-2006 for 《Vertical Turbine Pump》, it owns the cycle lubrication bearing arrangement of patent. (patent code: 200620050566.6)

Features
1. Operation smooth, safe and reliable, starting without exhausting vacumn, service life long.
2. The volumn of the pump small, less occupied land area, the length under foundation adjustable, applicability strong.
3. Flowing channel simple and reliable, saving the investment for construction of the pump house.
4. Structure reasonable, convenient for mounting and dismantling, easy to maintain and inspect.
5. Efficiency high, operating cost reduced.
6.  Higher standard, and stronger generality for component.

Structure features:
1. Series LK ,LB pumps are of vertical single stage and/or multistage centrifugal or mixed flow with diffuser types.
2. The following structure types are available for the pump:the discharge opening above and/or under the mounting foundation(Type Code named S and X respectively);the axial thrust force born by the pump and/or by the motor(Type Code named T and D);lubricating water from outside and/or from the pump itself.
3. The intake sump is of wet pit and/or dry pit types.
Wet pit type:lower part of the pump inundated in the intake sump.
Dry pit type:the water enters into the pump,the suction bellmouth is connected with the inlet  pipe of the pump by means of elbow bend pipe of 900.
4. When the axial thrust force and the weight of the rotor are born by pump itself,the thrust bearing of the pump is lubricated with dilute oil and is equipped with a temperature detector Pt100 to detect bearing temperature and a pressure type thermometer to detect the temperature of lubricating oil.
5. The antielectrochemical corrosion appliance is adopted for the part of the pump contacting the liquid to ensure the service life of the pump when seawater is pumped.
6. The clearance between the impeller and the impeller chamber,i.e.the rotating component and the static component,can be easily adjusted on the pump mounting foundation.
7. The motor terminal box and pump external lubricating water pipe are lied on left when viewed from outlet to pump. It also can installed in any other direction base on guest of demand.
