RTM Series Venturi Vacuum Pumps

RTM Series pump mounted on extrusion
Ideally suited for use in dusty and dirty environments, RTM cartridges replace failed or clogged multi-stage pumps, minimizing downtime and maximizing productivity. RTM cartridges thread directly into existing multi-stage vacuum pumps and vacuum grippers for immediate, reliable, trouble-free operations.

Vaccon's advanced venturi design generates high internal velocities that carry dirt through and out of the pump. With no elements to impede flow or trap dirt, Vaccon pumps don't require filters or maintenance and never lose suction. Multi-stage pumps function using flap valves that clog from ingested environmental debris. Filters are required to protect the flap valves. Screens are added to vacuum cups to protect filters. Any or all of these parts can clog, causing loss of suction. Loss of suction causes production to stop until maintenance is performed and/or pump and filter replacement occurs. Vaccon RTM high performance Mid Series cartridges operate continuously without maintenance, the need for costly filters or cup screens, eliminating downtime, increasing productivity and improving profitability.

Available as a complete pump assembly or just the threaded cartridge, Vaccon's RTM Series is directly interchangeable with installed multi-stage units, eliminating the need to retool existing production equipment. Simply remove the threaded multi-stage cartridge and screw-in the Vaccon RTM single‑stage replacement. Full pump units can be exchanged in minutes in many cases. The RTM Series compact size gives the flexibility to allow installation in nearly any space.
