9120 Air Drum Pump

Industrial Grease Transfer Solution The 9120 Air Drum Pump is a reliable pneumatic pump designed specifically for transferring grease from standard 120 lb drums. This workshop-tested pump uses regular compressed air to move thick grease through maintenance systems without the hassle of manual pumping. With its powerful 55:1 pressure ratio, the 9120 delivers grease at 0.7 lb/min (317 g/min), making it perfect for busy maintenance shops, manufacturing plants, and industrial settings where equipment needs regular lubrication. The simple design means fewer breakdowns and more uptime for your maintenance team.

The 9120 is a compressed-air operated drum (barrel) pump designed to dispense high-pressure grease from large drums (fits 120 lb / 55–60 kg drums). What pump ratio and output does it provide? The 9120 is a high-ratio (55:1) piston pump giving approximately 0.7 lb (≈318 g) of grease per minute under rated conditions; actual output varies with air supply and grease viscosity. What connections and threads does it use? Standard connections include a 1/4″ NPT grease outlet, 1/4″ NPT air inlet, and a 3/8″ NPT relief/pressure port; a bung adapter and return tube are supplied for 120 lb drums. What air supply is required? The pump runs from a compressed-air source; operating air pressure and flow influence pump output — use the manufacturer’s recommended air pressure, filtration and lubrication for the air motor. What greases can I use with the 9120? Designed for mineral and synthetic greases commonly used in industrial systems; confirm compatibility and temperature range for very heavy or specialty greases before use. What container sizes does it fit? Configured for 120 lb drums using the supplied bung adapter and return tube; family variants of this pump can support other drum sizes (35–400 lb) with appropriate adapters. Is the 9120 suitable for distribution lines and high-pressure systems? Yes — it’s a high-pressure grease pump intended to feed distribution lines or single-point high-pressure greasing; always use appropriate pressure reliefs and system protection devices. What safety and installation notes should I follow? Use the supplied drum cover/bung adapter and follow the installation manual: do not over-pressurize the drum, install an air filter/regulator, verify hose and fitting pressure ratings, and relieve drum pressure before disconnecting. What accessories are normally supplied or recommended? Typical packages include bung adapter, return tube, drum cover; optional items are high-pressure hose, grease gun/nozzle, flow meter and mounting bracket. An air filter/regulator and safety relief valve are recommended if not already fitted. How should the pump be maintained? Regularly inspect the air supply (filter and oiler), seals and valves; keep suction and return tubes clean; check pistons and gaskets for wear and replace parts per the vendor maintenance schedule to avoid contamination and performance loss.
