Advantages of screw pump：

1. It  can transport  high  viscosity  medium.Depending  on  the size of  the pump,the  viscosity  of  the  medium is  in  the  range of  0 centipoise(CPS)  to 300,000 centipoise(CPS).

2. It can transport solid  particles,grinding  particles and fibers.The content can  be  up  to  40%  of  the  medium  ingeneral.  When the solid  in  the  medium  is  powdery fine  particles,the  maximum  content  can  be  as  high as 70%.According    to the size of the pump,the maximum particle size of the solid contained in the medium is 2mm-40mm.

3. The  output  liquid  is  continuous  and  even  with  stable  pressureand  small  agitation.Therefore ,the  composition  of  the  sensitive  liquid  will  not  change.

4. Flow rate is directly proportional to speed.The flow can be adjusted by changing the speed.Coupled witha variable   speed motor,the pump canbecome a variable pump,whichis very flexible.It can also achieve constant flow control    through  PLC  control.

5. The  pressure  can  be  automatically  adjusted  with  the  resistance   of  the  output  pipeline. Between  0-48(kg/cm2)   pressure,the  user  can  easily  adjust  to  the  required  pressure.In  this  way, it  can  not  only  save  energy,but also avoid the influence to the process  fow because of   too  high  or  too  low  pressure. Meanwhile it works better through  PLC  control  to  achieve  constant  pressure  transmission.

6. Simple  structure,less  wear,and  easy  maintenance.

Compared with other types of pumps:

1. Compared  with  the  centrifugal  pump,the  single  screw  pump  does  not  need  to install  alves.It  own  can  forma  closed cavity to  prevent  backflow  buffer,and  the  flow  is  stable  and  linear,without  large   fluctuations.

2. Compared  with the  plunger  pump,the  single  screw  pump  has  a  better  self-priming  capacity.According to the  size of  the pump,it can suck up to a height of about 8 meters of water column.

3. Compared with the diaphragm pump,the single screw pump can transport a variety of mixed impurities,and realize  the  mixed  transport  of  gas,liquid  and  solid,and  can  also  transport  the  medium  containing  solid  particles  or  fibers and a variety of chemical corrosive substances.

4. Different  from   plunger  pump,rotor  pump,diaphragm  pump  and  gear   pump,single  screw   pump  can   be  used  for  pharmaceutical filling and metering,and its metering accuracy is far higher than other pumps.

RL vertical pump:

1. Adjust the direction of the  pump,and  install  it  90°perpendicular  to  the  ground.It can  be  installed  in  the  pool,tank,culvert,deep  well  and  other  areas.The  length  of the pump can be extended on the basis of the actual depth.
2. The  installation  method  has  the  hoisting  type,bucket  type,the  pedestal  type  and  soon,and  the  length  can  be  customized  according  to  the  demand.
3. The stator and  rotor of the vertical  pump will  be inserted  into  the  pool  and will contact  with  the material.Therefore,anti-corrosion   should  be considered  for  the fasteners.The  installation  of the pump will be fixed in the light of different forms and the operation will be very stable.
4. The vertical pump can be installed on the automatic or manual lifting platform and the mobile car,which is convenient for the loading and unloading work of the special industry.
5. Flow Range:0.5-200m³/H
6. Pressure Range:0-2.4Mpa or higher
