C-KLR claw pressure-vacuum pumps can operate in vacuum and pressure modes at the same time. The suction and pressure operating points are almost independent, enabling highly flexible use in complex processes.
Fully dry, contact-free compression without oil in the compression chamber provides clean process gas, minimal wear and high reliability during continuous operation.
The range up to −0.6 bar vacuum and up to +1.0 bar positive pressure allows one unit to handle multiple process tasks, reducing system complexity and investment costs.
Integrated air cooling without additional cooling media and a built-in pressure-side air aftercooler provide low discharge temperatures and stable operation.
Optimized internal compression with high efficiency enables high differential pressures with low energy consumption and low life-cycle costs.
The robust design, minimal wear and long service intervals, with gearbox oil changes only after approximately 20,000 operating hours, keep operating costs very low.
The compact footprint enables easy integration into existing systems and quick access to all key components for service and inspection.
ATEX-compliant versions and options for multi-stage operation with multiple pressure levels are available, making C-KLR pumps suitable for demanding industrial and process applications.
Reliable vacuum and positive pressure for processes such as process-gas compression, venting systems and technology lines requiring clean, dry gas.
Combined vacuum and positive pressure for central vacuum systems, ionization, drying and reliable air supply in offset and rotary printing machines.
An ideal solution for packaging lines requiring vacuum and positive pressure at the same time, for example in package forming, product transport and support processes.
Simultaneous suction and pressure operation enables efficient pneumatic conveying of bulk materials in industrial processes.
Used in ventilation, drying, extraction and gas-compression systems requiring robustness, low maintenance and continuous operation.
Supports woodworking processes such as workpiece holding, extraction and conveying with one compact vacuum and pressure unit.
C-KLR pumps suit central systems requiring multiple operating modes, high reliability and optimized operating costs.
Fill in a short form and we will prepare a proposal for a vacuum pump or blower based on flow, pressure, and operating conditions. If needed, we can also include filtration, silencers, and accessories.
