Vacuum pump for methane extraction

2BV series liquid ring vacuum pump is used for steam pressure breathing of methane gas recovery in coal seam. The absolute pressure of 33mbar (97%) is 33 mbar. Under the condition of suction pressure below 80mbar, the long-term operation of vacuum pump is related to cavitation corrosion of protective pipe of ejector, that is, protecting atmosphere, suction pressure can reach 10mbar, and injection pump can be directly installed in compressor with pressure of 0.26 MPa (maximum absolute pressure). 2BV liquid ring vacuum pump and compressor will completely replace SK and 2SK series water ring pump and W, WY, WL series reciprocating vacuum pump with their excellent performance and advantages.

Vacuum pump for methane extraction
Main features:
Tightly coupled design facilitates installation and saves space.
Bearings are imported products, brand name is NTN or NSK
Standard seals are John Crane mechanical seals, eliminating leakage and easy to maintain.
2BV series products have cavitation protection ports. When they work near a limited vacuum, the cavitation protection port opens (or is connected to the separator) to get rid of the scream to protect the pump.
Aluminum bronze impeller has high strength and wear resistance. It can improve the corrosion resistance of the pump. If liquid flow components are made of stainless steel, the pump can be used under stricter conditions.
Unique outlet design can protect the pump from overpressure and ensure the best performance in the working range of 2BV vacuum pump.
Y2 series products are used in all motors. The protection level is IP54 or IP55 (IP44 normally), and the insulation level is F. (B normally).
The 2BVwater ring vacuum pump can realize all PTFE flexible seals, which can greatly prolong the service life under more harsh conditions.
Running smoothly, noise can be as low as 62 decibels.
