Elmo Rietschle 2BV3 151 – liquid ring vacuum pump of the L-BV3 series
The 2BV3 151 is a liquid ring vacuum pump of the L-BV3 series from Elmo Rietschle: compact design, bronze and stainless steel as standard, built-in cavitation protection. It draws in gases and humid vapours down to an inlet pressure of 33 mbar abs. (97 % vacuum) and, according to the data sheet, works without cavitation down to 80 mbar abs.; for lower inlet pressures the integrated cavitation protection is connected. Motor power 0.3 kW at 50 Hz.
Versions and motors
Listed are 2 order numbers from the data sheet in the standard material version (impeller bronze, housing stainless steel (bronze/stainless steel according to the data sheet)) with IE2 three-phase motors for various voltage ranges. Voltage, current, power, sound pressure level and weight are given with each version.
Pumping speed
Elmo Rietschle gives the pumping speed as a characteristic curve over the inlet pressure (100 % saturated air, 20 °C, operating liquid water 15 °C, tolerance ±10 %). Ehrler & Beck determines the pumping speed for your operating point.
