Orion Motor Tech 55 Gallon Drum Pump — Lever-Action Pump for 15–55 gal, 10 fl oz/Stroke, AISI 1045 Steel

Orion Motor Tech’s OMT 55 Gallon Drum Pump is a lever-action barrel pump that lets you transfer viscous liquids from 15 to 55 gallon drums quickly, delivering about 10 fl. oz. per stroke for controlled, low-mess dispensing.

Designed for garages, workshops, service bays and on-site field work, this lever-action drum pump combines heavy-duty AISI 1045 steel construction with a telescoping suction tube and a wide 3/4" outlet to reduce back pressure. The kit includes thread seal tape, two wrenches and a storage case so you can install and carry the pump with everything you need. It’s built to handle diesel, motor oil, transmission fluid and other heavier fluids while giving a comfortable grip and simple hand-operated control.

How much fluid does the pump move with each stroke?

The OMT lever pump dispenses roughly 10 fluid ounces per downward stroke, which makes it easy to meter fluid without an electric motor. That volume balances speed and precision for most automotive and maintenance tasks.

• Approx. 10 fl. oz. per stroke for predictable transfers
• Hand lever control for incremental dispensing
• Wide outlet reduces back-pressure for smoother flow

Which drum sizes and fluids are compatible?

The telescoping suction tube adjusts to fit drums from 15 to 55 gallons, so you can use one pump across different containers. It is designed for heavier liquids such as diesel, motor oil, gear oil and transmission fluids, not for corrosive acids or reactive chemicals.

• Fits 15–55 gallon drums via adjustable suction tube
• Suitable for diesel, motor oil, heavy oils, and transmission fluid
• Not intended for strong acids, solvents, or reactive chemicals

How durable and serviceable is the pump for daily garage use?

Constructed from AISI 1045 steel, the pump body and components are corrosion-resistant and sized for repeated use in professional settings. The simple lever mechanism is easy to maintain; included wrenches and thread seal tape let you tighten fittings and replace connections quickly.

• AISI 1045 steel construction resists wear and corrosion
• Removable suction tube for cleaning or replacement
• Accessory kit (wrenches, tape, case) for fast serviceability

How easy is it to install and carry on the job?

Installation requires threading the pump into the drum bung and adjusting the telescoping tube to the drum depth — the included thread seal tape and wrenches simplify this. A molded storage case keeps the pump and accessories protected for transport between job sites.

• Threaded installation with included seal tape and wrenches
• Telescoping tube adjusts without special tools
• Storage case organizes pump, tools, and tape for portability

Who is this for: Mechanics, fleet technicians, maintenance crews and serious DIYers who need a rugged, manually powered drum pump for heavier fluids will find the Orion Motor Tech OMT 55 Gallon Drum Pump practical and reliable. If you require electric pumping, chemical compatibility for aggressive solvents, or metered precision to the milliliter, choose a model designed for those specific needs; for straightforward, heavy-duty liquid transfer from common drums, this lever-action pump offers durability, portability and predictable performance.
