Due to their suitability as vacuum pump or compressor, they are used in a wide range of applications such as filtration, gas sample taking, vacuum drying, and automation engineering. By means of the integrated manometers, the vacuum and pressure values can be monitored permanently. These pumps are suitable for dry or aqueous vapour applications only. Benefits: • Dry-run technology for physical applications • Can be used as vacuum pump and compressor • Regulator valve with manometer at suction side • Regulator valve with manometer at pressure side in models with compressor function • Condensate pre-separator to protect the pump from liquid throughput • Silencer for noiseless operation • Feet with suction cups for a safe stand at the workstation Scope of delivery: WOB-L piston pump with manual pressure regulator, vacuum or pressure manometer, exhaust silencer, liquid pre-separator, and mains cable. Power supply: 230 V 50/60 Hz 1 2 Type 2522 2534 2546 2581 Ultimate total pressure mbar 133 93 80 6.7 Suction rate 50/60 Hz m3/h 1.1/1.3 1.7/2.0 2.3/2.7 4.9/5.9 Overpressure max. bar 7.9 5.8 5.2 – W × D × H mm 206×224×254 206×224×254 254×191×229 432×191×305 Weight kg 5.3 5.3 6.3 11.2 Order No. 10 92 42522 10 92 42534 10 92 42546 10 92 42581 More than 20,000 articles in this catalogue – and still more on our website!
