Modular vacuum pumping unit VacUnit

rotary transfercompactautomatic

Overview
The Vogelsang VacUnit is a compact vacuum pumping station for grey and black water collection in vacuum wastewater systems. Designed as a centralised unit, the VacUnit maintains the vacuum required for effluent transport and enables direct inline discharge of mixed air/liquid phases into downstream wastewater infrastructure. Integrated Vogelsang VX-series rotary-lobe pumps deliver multi-phase, self-priming operation without the need for separate vacuum tanks.

Benefits

• Compact footprint for constrained installation sites
• High availability via duty/standby pump configuration (DP)
• Simplified system design without separate vacuum collection tanks
• Reduced maintenance scope thanks to QuickService pump concept
• Inline conveyance of air and liquids in a single operation
• Insensitive to foreign matter and clogging; tolerant to dry running

Basics / Operating principle
The VacUnit maintains the vacuum level required for transport of wastewater in vacuum sewer systems. Its multi-phase pumping concept conveys air and liquid simultaneously and discharges them inline into downstream wastewater systems, eliminating the need for additional vacuum collection tanks and separate vacuum/sewage pumps.

Models

• VacUnit DP (double pump station): Dual-pump configuration with redundant units and intelligent pump control for continuous operation and handling of peak loads.
• VacUnit SP (single pump station): Single-pump configuration using a Vogelsang VX-series rotary-lobe pump for reliable, quiet operation and simplified maintenance.

Features

• Vogelsang VX-series rotary-lobe pumps with QuickService design for fast maintenance
• Duty/standby redundancy in DP versions for increased uptime
• Multi-phase pumping enabling inline discharge of liquid and air

Options

• Electric heating elements for frost protection and safe outdoor use at low temperatures
• Operating data acquisition, online monitoring and remote maintenance via control interfaces; VEBSys web portal available for remote access and support
• Containerised walk-in machine room (20' or 40') with space for additional equipment and customised layouts
• Weatherproof and soundproof enclosure with aluminium profile frame, insulated sandwich panels, ventilation grilles and service access panels
