Boerger rotary lobe pumps are self-priming, valveless, positive displacement pumps designed to handle a wide range of fluids—from low-viscosity liquids to highly viscous, abrasive, and solids-laden media. Built with a modular design, these pumps offer maximum flexibility, easy serviceability, and long-term reliability.

Key features include reversible operation, dry-run capability (short-term), and pulsation-free flow. All wetted parts can be customized to suit the application, with a range of rotor materials, coatings, and sealing systems available.

Engineered using Boerger’s Maintenance-in-Place (MIP®) design, wear parts can be quickly replaced without removing the pump from the piping system—minimizing downtime and lowering life-cycle costs.

Ideal for industries such as:

• Wastewater and Sludge Treatment

• Biogas and Agriculture

• Chemical and Petrochemical

• Pulp and Paper

• Oil and Gas

• Food and Beverage

• Marine and Offshore

Performance range:

• Flow rates up to 7,500 GPM

• Pressures up to 232 PSI

• Viscosity handling up to 1,000,000 cP

Boerger rotary lobe pumps are trusted worldwide for reliable, efficient fluid handling—even in the toughest operating conditions.
