Product Description

Use ranges:

It is mainly applied to reconstruction of pump station,flood control and drainage,urban flood control pump station,irrigation pump station,amusement park and large flow drainage pump station.


Production introduction:

Buoy axial-flow pump is a replacement product of traditional split type water pump-motor unit.The pump unit and motor are coaxial integration., The motor driving the water pump is a dry fully closed submersible three-phase asynchronous motor. The submersible pump can be immersed in water for a long time and has good sealing and insulating effects,not only having efficiency of traditional pump unit,but also having the incomparable advantages of energy saving and initial investment reduction compared to the traditional products.


Product characteristics:

(1)The cable adopts the cover type pure red copper,full square special submersible cable,the cable installation protection is done very well.

(2)Bearing is made of domestic brand by “Wafangdian”,the P5 precision grade is two grades higher than the ordinary motor bearing: High precision,long service life,good quiet performance,can bear axial force,large bearing capacity.

(3)We adopt 3-disc precision bearings to coordinate positioning.

(4)Our enameled wires are made of 99.999% pure red copper, adopt drawing wrapped insulating paint by sino-Japanese joint venture construction period,magnetic permeability is 15% higher than domestic process.

(5)The whole structure of our motor adopts YE3 high-efficiency and energy-saving technology,which saves 15% energy and power compared with ordinary Y2 series.

(6)The impeller is made ofr stainless steel 304 ( pls inform us in advance when ordering)

Performance parameters:

(1)Water head range 1-20m( according to the designed water head range)

(2)Water flow 0.1m3/s~~3.6m3/s,means 300m3/h~~15000m3/h (according to the site water intake and the designed displacement and product quantity)

(3)Motor rated power 18.5KW~~300KW ( the designed value)

(4)Rated voltage grade  380V/660V  high voltage should be customized (voltage)


Ordering  instruction:

1.the accurate product model,performance parameters(water flow,water head range,motor power,blade mounting angle) and operating voltage should be indicated in the contract. 2.the control cabinet should indicate the starting manner(direct start,self-coupling step-down start,soft start, variable frequency starting,etc.),liquid level control manner (float level,pressure transformer digital display level),installation manner(indoor ,outdoor). 3.if a terminal box is needed,pls indicate if it is a control type or a linear type. 4. The normal supply length of the submersible cross-flow pump cable is 8meters,if you have special requirement,pls specify. 5.if there is other special requirements,pls contact our technique department.
