Notice of advertisement publication in the February 2, 2023 issue of Nikkan Kogyo Shimbun "Pump Special Feature"

A pump that uses compressed air to transfer liquids by utilizing internal pressure! It minimizes residual liquid, is energy-efficient, and is suitable for safely dispensing highly flammable liquids in small quantities.

◎Explosion-proof design that does not use electricity ◎Double safety structure for peace of mind ◎Can be stored in a sealed manner ◎Compatible with high-viscosity liquids ◎Low failure rate ◎Efficient liquid discharge ◎Discharge method can also be selected 《Benefits》 ●Minimal residual liquid (approximately 200cc), capable of efficient discharge ●Safe transfer of volatile and flammable liquids ●Quiet operation with a 1 horsepower compressor ●Low air consumption and energy-saving ●Acceptable for small amounts of foreign matter contamination ●Continuous operation possible 《Features》 ●Dedicated to JIS standard 200L closed drums (large cap G2) ●Designed for discharge only with sealed pressurized drums, not for recovery ●Double pressure reduction with a regulator and safety valve for added safety ●Equipped with an anti-static grounding wire (only for G, AS, SUS types) 《Mechanism of the Air Pressure Pump》 This pump inserts depressurized compressed air into the drum, changing the internal pressure of the drum to discharge and draw in liquid. Since there are no obstacles in the flow path, it can handle liquids with foreign matter contamination and viscosity (up to 3,000 cP) without failure. Additionally, being air-operated, it can be used with liquids and environments that pose a risk of ignition or explosion. *Flow meter and gun nozzle included; foreign matter contamination not allowed.
