<1> GENERAL INTRODUCTION AND APPLICATION

LP Type Long-axis Vertical Discharge Pump is mainly used for pumping sewage or waste water which are non corrosive,at the temperature lower than 60 and of which suspended substances are free of fibers or abrasive particle s, cont ent is less than 150mg/L.On the basis of LP Type Long-axis Vertical Discharge Pump LPT type is additionally fitted w ith muff armor tubing with lubricant inside, serving for pumping of sewage or waste
water, which are at the temperature low er tha n 60 and contain certain solid particles, such as scrap iron, fine sand,coal powder, etc.LP(T) Type Long-axis Vertical Discharge Pump is of wide applicability in the fields of public work, steel and iron metallurgy,chemistry, paper-making, tapping water service, power station and irrigation and water conservancy, etc.

<2> PERFORMANCE RANGE    

Flux: 8 m3/h ~ 60,000 m3/h
Head: 3m ~ 150m.
Power: 1.5 kW ~3,600 kW  

<3> OPERATIONAL CONDITIONS

1.The temperature of medium shall not be higher than 60 .
2.The medium shall be neutral and PH value between 6.5~8.5. If the medium is not consistent to the requirements, specify
in th e order list.
3.For LP type pump, the content of suspended substances in the medium shall be less than 150 mg/L; for LPT type pump,
the max. Diameter of solid particles in the medium shall be less than 2 mm and the content less than 2 g/L.
4.LPT type pump shall be connected w ith cl ean water or soapy water outside to lubricate the rubber bearing. For twostage
pump, lubricant pressure shall not be less than half of operational pressure.
5.The first stage impeller of pump shall be imm ersed i n 0.5m above at min. water level and generally it is suggested to
be within 2~3 m.
6.The wellbore shall be straight.
7.Specify the depth of well in the order list.
8.Special operational condition is subject to agree ment or technical agreement.

<4>STRUCTURE SPECIFICATION

1.The inlet of LP(T) Type Pump shall be vertical downwardand the outlet horizontal above or under the base.
2.The impeller of pump is classified into enclosed type and half-opening type, and three adjustments: non-adjustable, semiadjustable and full adjustable. It is unnecessary to fill the water when the impellers are fully immersed in the pumped liquid.
3.On the basis of LP Type Pump, LPT type is additionally fit with muff armor tubing and the impellers are made of abrasive resistant material, widening the applicability of pump.
4.The connection of impeller shaft, transmission shaft, and motor shaft applies the shaft coupling nuts.
5.It applies water lubricating rubber bearing and packing seal.
6.The motor generally ap plies standard Y series triphase asynchron ous motor, or YLB type triphase asynchronous motor as requested. When assembling Y type motor, the pump is designed with anti- reverse device, effectively avoiding reverse of pump.
