KVA Single Stage, Oil-Sealed Rotary Vane Vacuum Pumps

KVA oil-flooded, multi-vane vacuum pumps are single stage, air cooled and direct driven. This simple design ensures the reliability and the durability that is required in the vacuum industry.  The performance of the KVA rotary vane vacuum pump has been optimized to provide even deeper vacuum levels than before. Most models can achieve ultimate pressure levels near 0.1 mbar.

The KVA has been engineered to provide convenient service access to both the oil and filters. Its direct-coupled and air-cooled design requires very little additional maintenance.  The small footprint of the KVA pump allows for maximized tabletop and floor space. A smooth and quiet operation can be expected due to the intentional pump design and vibration isolation.
