What is a Open hopper feed progressive cavity pump in bearing block design

Open hopper feed progressive cavity pump in bearing block design is a kind of progressive cavity pump which also has a enlarged rectangular hopper, coupling rod with auger and force-feed chamber with taper.

Because it is a bearing block design, it can cooperate with a variety of drivers. Its structure is stable and can bear more pressure and torsion.

The Features of Open hopper feed progressive cavity pump

  • Open hopper cavity pump larger hopper, larger capacity
  • Special coupling rod with auger has greater torque and stronger propulsion
  • The large force-feed chamber with taper is more conducive to the transportation of materials
  • Bearing block design, more diverse driving methods
  • The structure is stable and can withstand worse working conditions
  • Easy to disassemble and maintain
  • Continuous low pulsation transportation, not affected by pressure and viscosity
  • It can transport media with higher viscosity and poor fluidity
  • High efficiency and long life
  • Stator with hopper-shaped entrance for optimal filling of the conveying chamber
  • Reinforced screw

The Applications of Open hopper feed progressive cavity pump

Generally used for high viscosity, dense or fluffy media without bridging phenomenon in environmental protection, food and chemical industries;

It is especially suitable for continuous and low-pulse transportation of fermented renewable raw materials, liquid fertilizers, process water, ground biological waste, food waste, pre-processed slaughterhouse waste, concentrated substrate, thickened substrate and sludge.

What is the difference between PD and dynamic pump?There are two major types of pumps—dynamic and positive displacement. Dynamic pumps maintain a steady flow of the fluid whereas, positive displacement pumps contain individual portions of fluid that are enclosed before they are moved along.

A fluid film is needed to keep the sliding (contacting) surfaces lubricated. These pumps fail when run dry. Progressive cavity pumps are slower moving and don’t produce large amounts of flow.

Rotary lobe pumps can usually be serviced by one worker and do not require any lifting equipment. Progressive cavity pumps are generally larger than rotary lobe pumps and they require connected piping to be removed and the pump to be disassembled to maintain components in the wet end.

A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.
