No lubricating oil inside the pump chamber, oil-free exhaust, no oil vapor contamination; ideal for laboratory, medical, pharmaceutical, food and precision instrument applications.
No medium pollution
The diaphragm completely isolates the gas chamber from the driving structure; pumped gas will not be contaminated by lubricants or internal parts, suitable for corrosive, pure gas sampling.
Corrosion resistance
Can be equipped with PTFE, EPDM and anti-corrosion diaphragms and valve materials; stable for corrosive gas, volatile vapor in chemical and environmental industries.
Low noise & low vibration
Small mechanical impact, smooth operation, much quieter than piston vacuum pumps; suitable for indoor laboratory and desktop use.
Simple structure & long service life
Few wearing parts, mainly diaphragm and check valves; easy to maintain, low failure rate, long operational lifespan.
Small size & lightweight
Compact structure, easy to install, portable, convenient for instrument integration and mobile equipment.
Dry running allowable
Can run continuously without liquid medium, no damage from dry operation; wide adaptability for intermittent and continuous working conditions.
Low maintenance cost
No regular oil replacement; only regular replacement of vulnerable diaphragms and valves, low daily operating cost.
