Product catalog summary
Overview: The BLW Rotary Lobe Vacuum Pump is a positive displacement air blower designed for high vacuum applications. It features trilobal rotors with minimal clearances, synchronized by timing gears through an oil injection assembly. The pump is oil-free and water-free, with oversized rotor shafts and a standard non-return valve.
Specifications: Various models are available, each with specific hydraulic motor data such as displacement, operating pressure, maximum continuous pressure, and RPM. Models support both left and right shaft rotation, with integrated multiplier gearboxes and pulley options.
Cooling System: An optimized air injection cooling system limits heating during continuous operation, with flow sections designed to minimize load losses and maximize cooling efficiency.
Technical Data: Detailed technical data includes volume displacement at maximum speed, vacuum pressure, weight, and sound pressure levels, measured with silencers at 80% max speed and 60% vacuum rate.
Dimensions: Detailed dimensions for each model include measurements for components such as shaft diameter, length, and width.
Optional Accessories: Customization options include hydraulic and pneumatic revolving changeovers, synthetic oil, aluminum air filters, vacuum and pressure relief valves, speed sensors, and silencers made from stainless steel or painted carbon steel.
Compliance: BLW pumps are available in ATEX versions for explosive environments, compliant with II 2/2G Ex h IIB T3 Gb standards.
