W series screw pumps
Three screw pump with polymer-coated running casing for dirty or low-viscosity media at differential pressures up to 120 bar.
Description
The W series is used for dirty or low-viscosity media such as cooling lubricants containing abrasive metal residues, pumped at high pressure with viscosities of about 1 mm²/s. The running casing is coated with a resistant polymer that can absorb particles, and the balancing cylinder has orifice inserts to reduce leakage and keep efficiency high.
Key features
- Delivery rate 15 to 290 l/min; max. differential pressure 120 bar
- Polymer-coated running casing
- Hydrodynamic balance reduces wear and noise
- Dry or in-tank (wet) installation, with the discharge flange above the tank cover
Applications
- Cooling lubricants and other dirty or low-viscosity media
