HNZXIB Diaphragm Vacuum Pump 20L/min 2-stage for Laboratory Evaporation/Distillation

>>>> INTRODUCTION
P20 vacuum diaphragm pump is a gas-based two-stage pump, all parts in contact with the gas are PTFE material, high corrosion resistance, wide application, it can completely replace the water circulation pump, suitable for Chemical, pharmaceutical, petrochemical and other industries on the corrosive gas treatment, such as suction filtration, vacuum distillation, rotary evaporation, vacuum concentration, centrifugal concentration, solid phase extraction.

>>>> FEATURES
1. Resistant to chemical corrosion: Corrosion-resistant vacuum pump using a special diaphragm (membrane surface PTFE coating) and the pump head design, including all the joints and pipelines, gas contact with the parts are imported PTFE material, so Resistant to most of the corrosive gases; the same time, electrical switches and the shell also do anti-corrosion treatment, in particular, the transmission mechanism and the circuit part of the use of corrosion-resistant materials to form a closed space, completely isolated from the external environment so that the vacuum pump is not only resistant to corrosive media, But also perfect for corrosive environment, completely solve the problem of chemical resistance of the vacuum pump.
2. Pollution-free, maintenance-free: diaphragm vacuum pump can be completely recovered solvent to eliminate toxic and hazardous organic solvents on the environment pollution and
the health hazards to the operator and nearby people, even if the mixed solvent can be highly recycled; diaphragm pump It is a dry, dry, oil-free pump that keeps laboratories clean and quiet, eliminating the need for regular cleaning, pipe change, and water changes. The diaphragm vacuum pumps are 100% maintenance-free.
3. Low noise, low vibration: corrosion-resistant vacuum pump motor direct drive power transmission, no intermediate transmission parts, coupled with the diaphragm low-stroke, low noise characteristics, so the product noise can be maintained below 70dB.
4. Overheat protection: Each product is equipped with temperature protection switch, when the internal body temperature is too high will automatically shut down, wait for the temperature to cool and then start their own to ensure the stability and safety of the system.
