The maximum suction capacity of ZHONGNI 2BE1 Vacuum pump/compressor can reach 22,500m3/h. The lowest suction pressure can reach 33mbar A. When it is used as a compressor, its exit pressure can reach 0.35Mpa.A.

Owing to only one rotating part (impeller) and no direct friction of metals so abrasion is avoided even if it has run for many years.

ZHONGNI adsorbs others advantages and must not let you down.

Unique design

All ZHONGNI liquor pumps are designed according to flexible discharge valve and so they realize optimal efficiency. Whether 10KW power or 500KW power is need in your work spot, ZHONGNI liquor pumps always perform well. Patented design of flexible vent can make over-pressed in vacuum application be avoided. By self-regulation of discharge area, energy consumption is reduced. So it reaches optimal performance. Flexible PTFE valve board covers vent holes at outside of circle plate and is positioned by stainless steel board of its other side. This valve board changes its bend degree along with entrance pressure change. So target fluid can be discharged out of pump when its pressure reaches entrance pressure.

Features:

Simple structure: Single level, single action, axle-direction suction and discharge. Convenient maintenance.
Self-regulation: Vent with flexible valve board can self-regulate discharge-direction and make pump run with high efficiency at different suction pressures.
Wide pump scope: Limit absolute pressure can reach 33hPa.
Good adaptation: When used in corrosion sites, its flow passage components can be made by different materials.
Reasonable design: Gas-etching valve can be added to prevent gas-etching damage in higher vacuum condition. Spraying device can be added to pump high temperature gas.

After two times development, its structure is improved, operation is more reliable and performance is more stable.
■High reliability, easy maintenance.
■Low cost operation.
■Low noise.
■Even if it works without work fluid, its body won’t be damaged.
■Special material can be used to some corrosive fluid.
■We can provide close-circulation whole unit.

All specifications are all ready. Many materials are optional.

All kinds of models of ZHONGNI 2BE1 series are all ready. Their suction capacity can reach 22,500m3/h. Furthermore, top discharge and horizontal discharge are optional so it can be easily installed.
