Included in the trvx series are many sizes up to 100 hp. These vacuum pumps are widely used in the rough vacuum area up to 29" hg.v (25 torr). Applications in paper and pulp, plastics moulding and extrusion, cnc machines and routers, meat and poultry producers, vacuum packaging are just a few to mention. Following are additional benefits of this trvx vacuum pump series: ã¢ï¿½â¢ reduced footprint ã¢ï¿½ï¿½ the footprint of all trvx pumps is reduced by as much as 40 percent. The light weight and small size of these pumps increase portability. Even installation is easier. Ultimately, the reduced footprint reduces time and effort while boosting convenience. â�⢠reduced cost ã¢ï¿½ï¿½ both sealing fluid and energy costs are reduced by 25 percent due innovative hydraulic design. Materials are are more durable, operation efficiency are optimized. â�⢠improved performance ã¢ï¿½ï¿½ these liquid ring vacuum pumps offer a 10 percent improvement in horsepower performance over the conventional designs. Therefore, the pumps are more efficient, and more effective. â�⢠easier maintenance ã¢ï¿½ï¿½ based on design, these pumps have fewer components. Not only does this simplify maintenance, there is less wear and tear on the pumps themselves. Key specifications for all three pumps in the trvx series ã¢ï¿½ï¿½ the pressure range is from atmosphere to 29: hg.v (25 and 760 torr). Their capacity ranges from 200 to 1200 cubic feet per minute. These single-stage vacuum pumps have a vari-port design that includes external mounted bearings. There are also shaft-sealing options, such as a mechanical seal, which comes standard, as well as a stuffing box and double mechanical seal.
