VOGELSANG PRODUCTS
XRipper Twin Shaft Grinders
The XRipper Twin Shaft grinders provide high-volume coarse grinding for systems where large amounts of debris may be present in the wastewater or sludge. They protect downstream pumps and process components, preventing clogs, blockages, and damage. The monolithic ripper rotors are made of a hardened high-quality steel block.
Typical Applications
- Wastewater pumping stations
- Septage and FOG receiving stations
- Influent screenings grinding
- Primary scum
- WWTP sludge
- Dewatering equipment feed
- Hospitals and nursing homes
- Jails and prisons
- Resorts
- Truck stops and rest areas
Rotary Lobe Pumps
Vogelsang’s rotary lobe pumps are ideal for tough sludge applications involving heavy solids, viscous sludge, and abrasive liquids. Vogelsang pumps are constructed with ease of maintenance in mind. The entire wet end can be accessed for routine or preventative maintenance by simply removing the front cover. Wear parts can be replaced without disturbing connected piping.

Rotary lobe pumps are positive-displacement type pumps that use two or more lobes rotating around parallel shafts in the pump’s body to move liquids. They are widely used in the municipal water and wastewater treatment industries. They provide a compact, easy-to-maintain solution that can handle various applications. Since the movement of the pump’s lobes cause the pump to discharge a specific amount of fluid each revolution, the pump’s output can easily be controlled by varying the pump’s speed with a variable frequency drive (VFD).
Typical Applications inside Treatment Plants
- Septage and FOG receiving
- Primary sludge
- Primary scum
- Return-activated sludge (RAS), waste-activated sludge (WAS)
- Thickened waste-activated sludge (TWAS)
- Digester feed and recirculation
- DAF Thickening
- Dewatering equipment feed
- Slurries

RotaCut Inline Macerators
RotaCut Inline macerators provide precision reduction of solids, such as rags and other objects, before they cause damage to downstream pumps and equipment. Heavy solids such as stones and metal objects settle to the bottom of the pot, where they are removed from the stream entirely.
Macerators, or single-shaft grinders, are designed for inline pipe installations. They require liquid flow through the cutter assembly to operate. Macerators are conditioners as they condition the sludge solids into small, manageable particles, keeping pumps and downstream equipment safe. Solids such as hair, wipes, and rags are finely cut, allowing them to easily pass through downstream equipment without reconstituting. Macerators are best suited for advanced cutting after the headworks of a wastewater treatment plant.
Typical Applications inside WWTP

- Fats, oils, and grease (FOG) Receiving
- Septage receiving
- Primary sludge
- Primary scum
- Return-activated sludge (RAS), waste-activated sludge (WAS)
- Thickened waste-activated sludge (TWAS)
- Digester feed and recirculation
- Dewatering equipment feed
- Plastic reduction before land application of biosolids
Genuine Vogelsang Replacement Parts

At Envirep, we will help you choose the best Vogelsang parts for your equipment. Our goal is to provide easy-to-operate, low-maintenance components to ensure your equipment is back in service quickly.
Precise tolerances are critical to the performance of Vogelsang equipment. Even slight variances can generate significant inefficiencies, and using non-OEM components dramatically increases the risk of equipment failure. In addition, end-users must understand the dangers and risks of using replicated/pirated parts in Vogelsang equipment. These risks can be avoided by always using Genuine Vogelsang parts.
Vogelsang parts are machined accurately and custom engineered to fit each piece of equipment.
Please contact Envirep if you would like additional information or an on-site demonstration.
