Product Description
Catalogue sheet for 2BE4 
Introducing the 2BE4 Sries China Pumps Liquid Water Ring Vacuum Pump - a top-of-the-line product designed to meet all your vacuum pumping needs. This high-quality vacuum pump is perfect for a wide range of applications, from industrial to commercial use.
Usable in every branch of industry - meets the highest requirements for vacuum and filtration systems. Suitable for any rough vacuum and the conveyance of almost all process gases.
Performance curves for inlet pressures <160 mbar only available for 2BE4 30, 40, 50, 60.
The performance range are based on operating conditions with saturated 100 % relativer air at a temperature of 20 °C (68 °F), operating water at a temperature of Feuchte und 20 °C, 15 °C 15 °C (60 °F), and a discharge pressure of 1013 mbar (29.92 in Hg abs.).
Tolerance + 5 % for inlet pressure ≥ 250 mbar, acc. to PNEUROP. Toleranz + 5 % ≥ 250 mbar, PNEUROP. Calculation of individual performance curves is done acc. to individual
Sound pressure level
The noise levels are measured on bare machines in accordance with EN ISO 2151 and EN ISO 3746 (not including noise emitted from piping and auxiliary equipment). This corresponds to the normal operational state. Values refer to standard rotational speed, inlet and discharge pressures. Values that are specific to a purchase order are available depending on the scope of the order. Actual noise levels can be higher at working place due to background noise and conditions of installation.
In special cases are excessive vibrations agreed upon and permitted. / Measurement according to ISO10816-3.
