Vakuová pumpa s rotačními lopatkami, P 4 Z

Description Compact, two-stage rotary pump with high suction capacity. Automatic lubrication of the rotary valve and ball bearings using optimised oil pressure increases the final pressure levels achievable, stabilises the pump temperature and prolongs the pump’s working life. Includes direct drive with elastic coupling. Device exhibits good resistance to chemicals and a high degree of water vapour compatibility. A suitable mechanism prevents the oil from rising back to contaminate the recipient. Lightweight device that operates with low noise. High-quality parts make the device capable of continuous operation. The pump is complete and ready for connection with a full complement of oil, centring ring, locking ring, motor protection circuit breaker, mains switch and connection cable with mains plug Connecting flange: DN 16 KF Suction performance (Pneurop): 77/92 l/min at 50/60 Hz Final pressure (without partial gas ballast): 2 x 10-4 hPa Final pressure (with total gas ballast): 1 x 10-2 hPa Water vapour tolerance: 40 hPa Motor output: 200 W Oil capacity: 530 ml Supply voltage: 100 / 115 / 230 V, 50/60 Hz Dimensions: 415x150x235 mm3 approx.
