DWGM-20 DWGM-30 Corrosion Resistant Diaphragm Vacuum Pump
DWGM-20 and DWGM-30 corrosion-resistant diaphragm vacuum pumps are designed for reduced-pressure laboratory processes involving aggressive gases. A motor-driven diaphragm changes the pump-chamber volume to generate suction and discharge without oil in the vacuum path. Both models use a double-stage pump structure with PTFE pump heads and composite diaphragms, providing an ultimate vacuum of 5–8 mbar for continuous operation, with 20 L/min and 30 L/min flow options available.
- 20 / 30 L/min Maximum Flow Rate
- 5–8 mbar Ultimate Vacuum
- Double-Stage Pump Pump Head Type
- PTFE Pump Head & Composite Diaphragm
- FFPM Valve Disc
- Strong Acid / Base Gases Applicable Medium
Features of DWGM-20 and DWGM-30
- Core technology: PTFE and special material composite film has strong corrosion resistance; Improve the fatigue resistance and effectively prolong the service life of the diaphragm;
- There is no problem of oil mist pollution; Compared with rubber diaphragm, it is higher in air tightness, corrosion resistance and strength.
- Anti-hardening corrosion; No pollution, no maintenance, low noise, low vibration, overheating protection.
