2BE type liquid ring vacuum pump

Usage and Characteristics of 2BE Type Liquid Ring Vacuum Pump:

This series of pumps adopt a single-stage single-acting structure, featuring simple structure, convenient maintenance, reliable operation, and high efficiency and energy-saving advantages. Compared to widely used domestic SK, 2SK, and SZ series liquid ring vacuum pumps, they exhibit significant advantages such as high vacuum degree, low power consumption, and reliable operation, making them the ideal product among SK, 2SK, and SZ series liquid ring vacuum pumps. They are widely used in industries such as papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, stone, coal washing, ore dressing, and fertilizer.

Characteristics of the 2BE series liquid ring vacuum pump are as follows:

Belt pulley (belt drive) adopts a taper sleeve belt pulley, ensuring reliable operation, long belt life, and convenient disassembly.

Coupling (direct drive) adopts an elastic coupling, ensuring stable and reliable operation with a long service life.

The unique upper-positioned gas-water separator saves space and effectively reduces noise.

Mechanical seals (optional accessories) are all made of standard parts, ensuring no leakage during the long-term operation of the 2BE series vacuum pump.
