Adopting oil-free piston pump

Clean: without pollution of oil and smoke

Convenient: no need add oil to maintain daily

Safe: no plus pressure during using

Power Voltage: AC220V±22V，50Hz±1H

 Max negative pressure: ≥0.09Mpa

Noise:≤65dB (A)

Power:≤180VA

Pumping rate: ≥20L/min

Reservoir capacity: 2500mL/pc, 2pieces

No flow backwards pressure when the machine stops, so the liquid won’t flow backwards
