Progressive cavity pump CC series

for wastewaterslurryfor sand

Overview
The Vogelsang CC series (CavityComfort) are progressive cavity pumps engineered for handling highly viscous, abrasive and foreign‑matter laden media. The QuickService concept enables fast maintenance with minimal space and reduced downtime, offering flexible part‑replacement strategies and easy access to the shaft seal.

Key benefits

• Fast maintenance with minimal installation space using a swiveling rotor/stator unit
• No need to dismantle suction or discharge piping for many service tasks
• Multiple repair options: replace rotor/stator as one unit or individually
• Quality Cartridge mechanical seal replaceable from the drive end (motor removed) or via pumping chamber
• Large free passage (up to 108 mm) to reduce clogging by coarse solids
• Generous cardan shaft with protective sleeve to resist solids and fibrous matter

Models

• CC44 — Small capacity model for low flows; large free passage for resistance to foreign matter; quick service.
• CC55 — Compact model for medium flows; oversized cardan shaft for demanding applications.
• CC66 — High-capacity, high-pressure model for viscous or abrasive media with elevated solid content.
• CC77 — Largest CC model with QuickService design; very large free passage for coarse disruptive matter and rapid maintenance uncommon for this size.

Features

• Swiveling mechanism: rotor and stator can be swiveled as a single unit to avoid pipe disassembly
• Protected cardan shaft: two-joint design with protective sleeve that does not require removal for rotor change
• Seal options: Quality Cartridge mechanical seal accessible from drive end or pumping chamber
• Part-replacement strategies: stator+rotor as cartridge, full rotating unit swap or sequential replacement
• Optimized suction housing delivering a constant large free passage to prevent blockages

Options

• StreamLine suction housing — flow-optimized, flange-adaptable (vertical or horizontal arrangements)
• MultiConnect suction housing — quick connection for multiple suction lines and integrated foreign‑body separation
• Rotor‑stator geometries — M1 (single-stage), M2 (two-stage for higher pressures), D1 (long geometry for very viscous/abrasive media)
• Drive variants — geared motors, parallel-shaft gearboxes, hydraulic motors; versions for temporarily or permanently flooded operation

Application areas

• Biogas plants (feeding of freshly macerated organic suspensions, digestate handling)
• Wastewater treatment (abrasive sludges, high dry‑matter slurries)
• Transport of liquids with coarse foreign matter in industrial processes
• Any heavy‑duty application requiring short downtimes and easy onsite maintenance
