biogas substrate mixing progressive cavity pump
Product Overview Designed for livestock manure management and agricultural biogas systems, this pump combines substrate blending with positive displacement transfer. Prepared biomass enters the hopper while liquid manure or recirculated digestate can be introduced into the mixing zone. A feed screw moves the blended material toward the rotor and stator for steady delivery to a digester or process pipeline. The equipment can be integrated into commercial pig farm construction projects, including pump rooms beside steel structure livestock buildings.
Key Features
  • Open hopper accommodates prepared, viscous and fibrous feedstock.
  • Feed screw assists transfer from the mixing chamber into the pumping elements.
  • Rotor and stator provide continuous, low pulsation substrate conveyance.
  • Liquid inlet and hopper arrangement can be configured to suit the farm's blending process.
  • Service access, wear materials and drive arrangement can be selected for the operating duty.
Structural Components Typical components include an open receiving hopper, liquid feed connection, mixing and force-feed chamber, conveying screw, coupling assembly, helical rotor, elastomer stator, shaft seal, discharge connection, electric drive and mounting base. Component materials and sealing details are selected according to the substrate and site conditions.
Working Principle Prepared organic solids enter through the hopper and combine with liquid manure, digestate or process water in the feed zone. The rotating screw advances the mixture into the pumping section. As the helical rotor turns inside the stator, sealed cavities carry the substrate toward the discharge. Suitable upstream screening or size reduction should be specified when the feed contains stones, long fibers or other disruptive material.
Technical Specifications
  • Flow rate and discharge pressure: According to project requirements.
  • Motor power, speed and electrical supply: Customizable.
  • Hopper, liquid inlet and discharge connections: Available upon request.
  • Rotor, stator and seal materials: Selected for substrate chemistry, solids content and operating temperature.
  • Installation dimensions and mounting arrangement: Designed according to the farm layout and local conditions.
Applications Suitable for feeding agricultural anaerobic digesters with blended pig manure and prepared biomass; transferring thickened fermentation substrate; combining recirculated digestate with organic feedstock; and connecting livestock waste collection systems to centralized biogas facilities. Final pump selection depends on feed preparation, moisture content and the required pipeline duty.
Customization Options Hopper geometry, inlet position, connection sizes, drive configuration, wetted materials, sealing arrangement and control interfaces can be reviewed against the project drawings. Integration with conveyors, mixing tanks, manure storage pits and digester pipework is planned according to the farm process and available installation space.
Installation & Maintenance Install the unit on a stable, level foundation with access to the hopper, drive, seal and rotor-stator assembly. Support connected pipework independently and provide isolation and flushing provisions where required by the process. During operation, monitor feed consistency, seal condition, vibration and wear. Prevent dry running and follow the supplied maintenance instructions for inspection and replacement intervals.
Product FAQ

Can it handle solid manure directly?
Feedstock must be prepared and have sufficient liquid content for the selected pump. The allowable solids and fiber characteristics are confirmed during sizing.

Does the pump chop incoming material?
The feed screw assists mixing and conveying; it is not a substitute for a dedicated macerator or foreign-object separator.

What information is needed for selection?
Provide the substrate composition, solids content, expected flow, pipe length, elevation difference, operating schedule and electrical supply.
