VacuStar WR 2500 – 3100 - 4000
Liquid ring compressor vacuum pump
Liquid Ring
The liquid ring compressor vacuum pump
The series WR was developed especially for the high requirements on mounting in suction vehicles, municipal vacuum trucks and combination trucks (combined suction and water jetting). The series WR consists of 3 sizes with a volume flow of up to 4065 m³/h / 2393 cfm.

The advantages at a glance
- Swivel mounted pump between the mounting feet
- Suction and pressure flange can be connected electively on shaft side or opposite
- Mechanical seal
- Low weight design by using aluminum
- Connection flanges can be swiveled
- Installation friendly design
- Only one water drain
Optional
- Ceramic-coated housing and end covers for extreme conditions. Excellent resistance to abrasion, erosion and cavitation. Chemical resistance to acid and alkaline media.
- Stainless steel impeller made of V2A, corrosion and abrasion resistant, well suited for low temperature applications, resistant to weak organic and inorganic acids.
- The integrated cell ventilation protects the water ring pump against cavitation > Increased service life.
