Progressive cavity pumping unit CC-Cut

for biogasslurryself-priming

Overview
The CC-Cut combines a CC-series progressive cavity pump with an upstream RotaCut cutter to enable priming, pumping and pre-treatment of highly diverse viscous liquids containing solids, fibrous matter and disruptive foreign objects. The compact design supports integration into biogas and similar plants where reduced viscosity, debris separation and homogenization are required.

Key benefits

• Improved pumping capability by combining progressive cavity pump and cutter
• Reliable handling of highly viscous and challenging media
• Debris reduction and separation of heavy material before downstream equipment
• Small footprint thanks to compact unit layout
• Fast on-site maintenance and wear-part replacement (QuickService)

Basics / Function
The CC-Cut macerates disruptive solids, separates heavy material and homogenizes viscous suspensions to prevent blockages and malfunctions in downstream equipment. By reducing viscosity and floating layer formation, the system can lower energy demand for subsequent pumps and mixers.

Models

• CC-Cut / RCQ-33Gpro — Small, maintenance-friendly unit for low-volume flows; suited to treat and protect downstream units handling small batches of viscous media.
• CC-Cut / RCQ-43Qpro — Compact, easy-to-service unit for intensive preparation of viscous media with rapid on-site part replacement.
• CC-Cut / RCX-48G — Versatile, efficient system for economical preparation of larger volume flows of medium- to high-viscosity media; long service life and reliable heavy-material separation.
• CC-Cut / RCX-58G — High-capacity unit designed for continuous, intensive preparation and pumping of large-volume, highly viscous suspensions under demanding conditions.

Features

• Heavy material separation — Integrated separator in each RotaCut to remove stones and metal parts and protect cutter and downstream components.
• Swiveling mechanism — Rotor/stator unit can be swiveled for maintenance without dismantling the suction pipe.
• Protected cardan shaft — Oversized cardan shaft with two joints and protective sleeve for reliable power transmission and damage protection.
• Part replacement variants — Multiple replacement strategies: rotor/stator as a unit, rotating unit replacement, or individual sequential replacement.
• Cutting screen geometry — Optimized, reversible cutting screens in wear-resistant special steel to ensure smooth running and extended life.
• QuickService — Full QuickService accessibility so wear parts are replaceable in a few steps for fast on-site service.
• Compact design — Pump and cutter mounted to minimize suction length and overall footprint while keeping service access.
• Quality Cartridge — Pre-assembled mechanical seal cartridge to simplify and speed up on-site seal replacement.
• ACCplus — Optional online monitoring of cutter blade status for reduced maintenance effort and integration into control systems.

Options

• Rotor-stator geometries — Standard single-stage (M1), two-stage (M2) for higher pressures, and long geometries (D1) for very viscous or abrasive media.
• Cutting screens — Free passage sizes from 4 mm to 50 mm; stainless steel versions available for aggressive media.
• Auto-Reverse function — Detects blockages and periodically reverses to maintain cutting edge and performance while reducing energy use.
• Debris Removal System (DRS) — Continuously removes separated heavy material during operation with minimal medium loss.

Application areas
Primarily designed for biogas plants: pumping and preparing slurry, recirculate and organic suspensions that contain straw, grass, feed residues, stones, metal parts and other disruptive items. The CC-Cut can be used as a central pump-preparation unit to reduce downstream malfunctions and improve plant efficiency.

Maintenance & Service
All wear parts are accessible and replaceable on site. QuickService features and modular replacement options minimize downtime and enable rapid restoration of operations.
