Pneumatic Oil Pump 3:1 Ratio
Brief Overview
This pneumatic oil pump delivers reliable, consistent fluid transfer through differential air motor technology. The 3:1 compression ratio makes it ideal for standard automotive and industrial lubrication tasks. If higher flow rates are required, consider stepping up to a 5:1 ratio pneumatic pump or a high-capacity 50:1 variant for specialized applications. The clamping mechanism ensures secure positioning during operation, while the modular design minimizes maintenance downtime—a critical advantage when managing fleet servicing or high-volume shop operations.
Key Features
- 3:1 Compression Ratio – Balanced output for standard motor oils, synthetics, hydraulic fluids, and transmission fluids
- Double-Action Operation – Continuous pumping cycle reduces cycle time compared to single-action designs
- Clamping Mechanism – Prevents unintended pump movement during operation
- Adjustable 2" Bung Adapter – Accommodates various drum sizes (55-gallon and compatible containers)
- Piston-Driven Design – Differential air motor technology ensures smooth, consistent fluid delivery
- Long Service Life – Fewer moving parts reduce wear and simplify routine maintenance
- Suction Tube Assembly – Long dip tube enables efficient withdrawal from deep containers

Business Advantages for Resellers
- Margin-Friendly Entry Point – The 3:1 ratio covers the largest segment of routine servicing, making it an essential stock item with predictable turnover
- Minimal Training Required – Straightforward operation reduces customer support overhead
- Cross-Sell Opportunity – Stock alternative ratio pumps to offer tiered solutions based on customer viscosity and flow needs
- Low Maintenance Cost – Modular construction keeps warranty claims and service costs manageable
- Bundling Potential – Pair with drum packages, adapter kits, or suction hose assemblies to increase order value
Application Context
This pump is purpose-built for shops, fleet operations, and maintenance facilities that routinely service vehicles with standard lubricants. The 3:1 ratio provides sufficient pressure and flow for efficient oil transfer without over-delivering capacity (which would waste compressed air). It handles oils up to 150 SAE, covering most automotive and light industrial fluids.
Why This Matters to Your Customers
Mechanics and technicians need reliable, hassle-free fluid transfer. This pump eliminates manual pouring (safety hazard, waste), reduces operator fatigue, and ensures consistent delivery volumes. The clamping mechanism prevents accidental tipping—a real concern in busy shops where foot traffic is constant.
