Vogelsang’s rotary lobe sludge pumps are engineered for reliable performance in tough applications involving high solids, thick and viscous sludges, and abrasive materials. With a maintenance-friendly design that allows full wet-end access by simply removing the front cover, routine service is quick and efficient. Worn parts can be replaced without disconnecting piping—minimizing downtime and reducing total cost of ownership.

Key Features

• Versatile Performance: Pumps viscous, abrasive, and shear-sensitive materials with ease.
• Pulsation-Free Operation: HiFlo® twisted lobes ensure smooth flow and extend motor and coupling life.
• Compact & Self-Priming: Small footprint and strong vacuum capability simplify installation and startup.
• Non-Leaking Seals: Secure design prevents hazardous or odorous leaks.
• Variable Speed: Precisely control flow to match process conditions.
• Tool-Free Access: Wet end access without disturbing piping enables fast maintenance.

Advantages in Municipal Wastewater Sludge Pumping

• Handles Thick, Viscous Sludges: Maintains flow even with high solids content.
• Highly Abrasion Resistant: Low-speed, non-contacting components extend pump life.
• Efficient & Reliable: Proven energy efficiency in long-duty applications.
• Low Maintenance Requirements: Quick access to internals; no need to remove piping.
• Odor & Spill Containment: Non-leaking seals protect surrounding environment.
• Space-Saving Design: Compact footprint fits tight mechanical rooms.

In summary, the advantages of rotary lobe pumps in handling municipal wastewater sludge include their ability to handle viscous and abrasive materials, gentle pumping action, self-priming capability, efficiency, ease of maintenance, and flexibility to handle varying flow requirements. These factors make them a popular choice in wastewater treatment applications.

Typical Wastewater Treatment Applications

• Sludge Transfer: Between process stages or to storage tanks.
• WAS & TWAS Handling: Pumps thickened and return activated sludges reliably.
• Sludge Dewatering Feed: Interfaces with belt presses, centrifuges, or screw presses.
• Chemical Metering: Accurately doses polymers, lime slurry, and other additives.
• Digested & Primary Sludge: Performs well with treated biosolids.

The ability of rotary lobe pumps to handle a wide range of viscosities, solids content, and abrasive materials makes them indispensable in various critical applications within wastewater treatment plants.
