Design Features

1.Flexible model selection:

   Capacity range:1.8 m^3/h-1400 m^3/h;head renge::8m-125m;suction head:4m-8m;basic model & shunt model 195 specificationgs for impeller-cutting model A/B/C.It is easy for customer to make options among a wide variety of models.

   2.Extensive applications:

Since there are wide-ranging performance options and rellable design solution,it is adaptable to applications as follow:

1)High-rise water tank feeding & fire pump.

2)Long distance water supply.

3)Boiler water feeding.

4)Heating system air-conditioning system hot & cool water circulation.

5)Others.

3.Expenses saving:

The unique installation structure will save the floor space costly in moderm bulldings,leading to 40%-60% cut of construction investment.The perfect design contributes to long operation life,high efficiency,and low energy as well as 50%-70% cut of operation cost.

4.Simple installation:

The discharge diameter is as same as the suction diameter on the same straight line.To install the pump with the installation foot is as simple as fixing value.

5.Super quiet/low vibration:

The series adopt special environmental friendly design and hydraulic principle to reduce vibrations & noises during operation.The quiet,comfortable ideal living & working environment is created accordingly.

6.Long life:

The comprehensive design,including elimination of impeller-transferred axial thrust and bearing material’s selection,greatly improved the operation life of motor & pump.

7.Stable operation:

Add baffle structure to the entrance parts of pump,dispel disorderly flow,improve the cavitation performance,extruding chamber of big flow capacity adopts double cochlear model structure to balance the radial force and make pump operate stably.

8.Reliable seal:

There is balance type mechanical seal and unbalance type mechanical seal,according to the working pressure.The unique advanced sealing structure and quality seal parts provide the final solution for leaking.It contributes to the clean working environment.

9.Convenient maintenance:

This structure takes rigidity lengthened shaft coupling,after opening the shaft-coupling,you can replace the mechanical seal,don’t need to disassembly the motor and pipeline.

Using condition

   The transportation medium is clear water or liquid like water.There should not corrosion liquid in medium.The PH value is 4-10,The solid volumetric proportion≤0.2%,Granularity≤0.2mm.

   Speed rate:2960r/min or 1480r/min、980r/min

   Discharge capacity:1.8 m^3/h-1400 m^3/h

   Head:8m-125m

   Temperature of medium:-10℃-+80℃、+105℃

   Temperature of environment:≤+40℃;Height above sea level≤1000m;Relative humidity≤95%

   Max.working pressure:1.6MPa(200mm and less Dia.),1.0MPa(250mm and more Dia.)

   Max.working pressure=Inlet pressure+close valve pressure(Q=0).Inlet pressure≤0.4MPa.

   When the inlet pressure is more than 0.4MPa or the max.working pressure is more than 1.6MPa (≤200mm diameter),1.0MPa(≥250mm diameter),should bring out,so that,when producing,the parts of over flow and connection take magnesium iron or cast steel material.Mechanical seal can be selected to fit specially.

   Power:380V,50Hz

   Option:PN16-GB/T17241.6-1998 flange

   There is deflation valve on the pump,must deflate before operation to add the using life.
