Product Description

Product introduction:

HW pump is horizontal,single stage,single suction,vortex shell mixed-flow pump

Suitable for conveying clean water or other liquids with physical or chemical properties similar to water.

 The temperature of the liquid should not be higher than 50℃

Widely used in farmland irrigation and drainage,industrial and urban water supply and drainage.


Product characteristics:

1.HW pump mainly consist of pump cover,impeller,pump body,pump shaft,shaft sleeve and bearing body(diameter ≤350mm) or bearing frame(diameter ≥400mm)and other main parts

2.The pump cover is connected with the pump body and the inlet pipe respectively.There should be proper clearance between pump cover plane and impeller plane.Too small clearance will produce friction,too large will lead a large number of pressure water backflow in pump body,reducing the efficiency of the pump.The appropriate clearance for actual use is 0.3-0.7mm(push the pump shaft to the inlet of the pump),and the clearance can be adjusted by increasing or decreasing the thickness of the paper pad.

3.The shaft seal device consists of packing,packing gland,packing ring and seasoning box on the pump body(150HW and 20HW pumps without packing ring).Its role is to prevent the air from entering pump and prevent excessive water flowing from the pump along the shaft.


Use conditions:

It is mainly used in reconstruction of pump station,flood control and drainage,urban flood control  pump station,irrigation pump station,amusement park and other large flow drainage pump station.


Model implication:

Take 300HW-8A as example

300-- diameter of inlet and outlet of the pump(mm)

HW-- horizontal vortex shell mixed-flow pump

8-- designed water head(m)

A-- outside diameter of incised impeller or change the impeller with different performance


Performance parameters:

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

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

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

4.Rated voltage grade 380V/660V high voltage need to be customized (voltage)


Ordering instruction:

  1. the accurate product model,performance parameters(flow,water head range,motor power,blade mounting angle) and service voltage should be indicated in the contract.

  2. 2.the control cabinet should indicate the starting manner(directly start,self-coupling step-down start,soft start,frequency conversion start,etc.) and level control manner(float level,pressure transformer digital display level). Installation manner(indoor,outdoor)

  3. 3.if a terminal box is needed ,pls indicate whether it is control type or linear type.

  4. 4.the normal suply length of the submersible cross-flow pump cable is 8meters,if there is a special demand,pls specify.

  5. 5.if there is any other special requirements,pls contact with our technique.
