VacuStar WR 2500

Maximum performance for demanding mobile vacuum operations

The VacuStar WR 2500, WR 3100, and WR 4000 are the high-capacity models of the WR Series. Designed for heavy-duty suction vehicles and jetting trucks, these pumps deliver exceptional airflow rates up to 4,063 m³/h – making them some of the most powerful liquid ring vacuum pumps on the market.

Why choose WR 2500–3100–4000?

High airflow capacity – ensures fast and efficient operation, even in large-scale industrial cleaning

Rugged construction – stainless steel impeller and ceramic-coated options withstand abrasive and corrosive media

Built-in cavitation protection – integrated cell ventilation extends pump life

Flexible integration – multiple port positions and swiveling pump body for easy installation

ATEX-certified versions available – safe for explosive environments

Core Features: 

Eccentrically mounted rotor forms a rotating liquid ring that compresses air

Mechanical shaft seal ensures long-lasting, leak-free operation

Swiveling inlet and outlet ports for maximum installation flexibility

Central service water drainage for easy maintenance

Stainless steel impeller (V2A) → abrasion- and corrosion-resistant

Aluminum housing components reduce weight and improve heat dissipation

Integrated cell ventilation → protects the pump from cavitation damage
