Submersible — installed directly inside the tank or lagoon.
Dry-installed — positioned externally and connected via piping.
Key Pump Functions:
Homogenization and flushing of raw manure from the channel to the pre-lagoon.
Transfer of liquid fraction from the pre-lagoon to the main lagoon.
Many models feature an integrated chopping mechanism that macerates fibers, straw, and other solids. This ensures:
A more homogeneous substrate consistency.
Stable and uninterrupted system operation.
Accelerated anaerobic fermentation.
This equipment is distinguished by its reliability and durability, making it suitable for operations ranging from small farms to industrial-scale complexes. CRI-MAN PTS Series Submersible Pumps (Italy) The PTS Series is engineered specifically for pumping slurry, sewage, silage liquor, and other viscous, contaminated liquids containing fibrous and solid matter. These pumps combine power, wear resistance, and ease of maintenance, making them indispensable for Dairy Farms, biogas plants, and wastewater treatment facilities. Key Feature: The Double Chopping System combined with an open multi-channel impeller ensures efficient shredding of fibers and prevents clogging. All components in contact with the medium feature a nickel coating (up to 50 microns thick, hardness ~48 HRC), providing superior resistance to corrosion and abrasion. PTS Series Benefits:
Wide Model Range: From compact pumps for small operations to high-capacity units for large complexes.
Wear and Corrosion Resistance: Ensured by nickel coating and heavy-duty materials.
Easy Maintenance: Modular design provides simple access to components.
High Throughput: Capable of handling liquids with up to 12% solid content.
CRI-MAN PTE / PTEM Vertical Chopper Pump (Italy) The PTE / PTEM Series by CRI-MAN comprises powerful vertical pumps with a chopping system, designed for the transfer and simultaneous agitation of thick and contaminated liquids, such as manure slurry, wastewater, and biogas substrates. The vertical configuration and robust design make these pumps ideal for installation in tanks, reception pits, and lift stations. The pump features a multi-channel open impeller and a Double Chopping System, which effectively crushes fibrous and solid inclusions, ensuring clog-free operation and consistent flow. The PTEM version is additionally equipped with an adjustable mixing nozzle, allowing the operator to direct the fluid flow and perform agitation functions. Technical Specifications:
