Available vacuum pumps VN-461M.
The vacuum pump VN-461M is intended for the pumping out of air or uncondensible vapors which are not reacting with ferrous metals and vacuum oil in rooms with air temperature from +10 to +25 With at relative humidity of 60-65%. Also this pump is applicable for creation of a preliminary razryazhennost in vacuum pumps of high vacuum.
- productivity at free pumping - 50 l/min,
- partsialny residual pressure - 0,001 mm hg,
- total residual pressure - 0,02 mm of mercury.,
- pump shaft speed - 540 rpm,
- noise - no more than 80 DB at distance of 1 m from the pump.
These vacuum pumps one of the most reliable. Available illiquid assets from storage. Production of the pumps BH461 is stopped long ago, however the successful design does them very popular still. The belt drive lowering turns of a power shaft by 4 times and smoothing parasitic pulsations of a torque does the low-speed vacuum pump VN-461 very durable.
