vacuum pumps oil lubricated rotary vane pump or sliding vane vacuum pumps
vacuum pumps oil lubricated rotary vane pump or sliding vane vacuum pumps is the basis of years of scientific research and production experience combined with international advanced
technology developed energyefficient products, usually used for suction without solid particles, insoluble in
water, noncorrosive the nature of the gas, in order to form a vacuum in the airtight container and pressure.
By changing the structural material, the working fluid can also be used for pumping corrosive gases or corrosive
liquids. Widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy,
building materials, electrical appliances, coal washing, beneficiation, fertilizer and other industries.



Main feature :
1. bearings imported bearings, to ensure that the pump impeller 2BE1 precise positioning and high
stability during operation.
2. impeller material used in all welding nodular cast iron or steel, fully guarantee the stability 2BE1
pump impeller in a variety of adverse conditions, and greatly improve the 2BE1 pump life.
3. pulley (belt drive) using standard precision Bushes, reliable operation and long belt life, easy
removal.
4. coupling (direct drive) using a standard high-strength elastic couplings, flexible components using polyurethane materials, stable and reliable,
long service life.
5. pump used in all steel production, improve the 2BE1 pump life.
6. 2BE1 pump sleeve as the most easily damaged parts, all use stainless steel material than the
average life expectancy has increased by 5 times.
7. unique top-mounted gas-water separator to save space, and effectively reduce the noise.
8. casting resin sand casting in all, good quality, without the need to play tired, so 2BE1 heat
pump works best.
9. mechanical seals (optional) all imported parts, fully guaranteed 2BE1 series vacuum leak in
long-running process.
