Water Ring Vacuum Pump, Single-stage, 27 m3/h - 500 m3/h

Overview
A 2BV series water ring vacuum pump is suitable for pump air with water vapor, inspiratory pressure can reach 33mbar absolute pressure (97% vacuum degree). When the pump works under the inspiratory pressure closed to limit vacuum (work fluid saturation vapor pressure) for a long time, it should be connected to a cavitation protecting tube, in order to protect the pump. When working as the compressor, the greatest pressure is up to 0.26 MPa (absolute pressure).

As a new generation energy-saving product, with its excellent performance and numerous advantages, 2BV series water ring vacuum pumps will fully replace SK, 2SK series water ring vacuum pumps and W, WY, WL series reciprocating pumps.

Main Features
1. Direct coupling design, save space, easy to install and convenient maintenance.
2. All equipped with cavitation protection tube, if works under limit work pressure, open cavitation protection tube (or with separator connection) can maximum guarantee inspiratory effect under the condition of cavitation, and protect the pump.
3. 2BV series can be equipped with stainless steel impeller, high strength and durability, and improves the corrosion resistance of the pump.
4. Unique flexible air outlet design, won't produce over compression, ensure its performance efficiency is the best.
5. All adopt Y2 series motor, IP54\IP55 protection (ordinary, IP44), insulation class F (ordinary is class B insulation).
6. The flexible seal can be completely PTFE, which can greatly extend pump service life under harsh conditions.
