Pneumatic Oil Pump, 5:1 Ratio, Double-Action Air-Operated Piston Pump

Overview

This 5:1 ratio pneumatic oil pump is engineered for high-volume fluid transfer in professional service environments. The double-action air-operated design delivers consistent, reliable performance across motor oils, synthetic blends, hydraulic fluids, gear oils, and automatic transmission fluids up to 240 SAE. The clamping mechanism and differential air motor design minimize component wear while maximizing operational lifespan. For shops requiring higher flow rates or different ratios, higher-ratio pneumatic pump options and lower-ratio alternatives are available to match specific application requirements.

Key Features

• Double-action air-operated piston pump – Consistent pressure delivery with minimal pulsation
• 5:1 fluid-to-air ratio – Balances flow rate and air consumption for typical shop operations
• Clamping mechanism – Secure mounting and stable operation during continuous use
• Differential air motor design – Fewer moving parts reduce maintenance intervals and component fatigue
• Universal fluid compatibility – Motor oil, synthetic oil, hydraulic oil, gear oil, and ATF (up to 240 SAE)
• Adjustable 2-inch bung adapter – Direct integration with standard oil drums and containers
• Stainless/aluminum pump head – Corrosion resistance and long service life
• Side-mounted air ports – Flexible air line integration; exhaust outlet for clean discharge
• Sealed gasket and brass locking nut – Prevents leakage and ensures stable suction tube connection

Business Advantages for Resellers

• High turnover product – Essential for any professional shop or fluid service operation
• Bulk-friendly specifications – Standard 5:1 ratio meets 80% of typical shop requirements
• Low maintenance cost – Smart design with fewer parts translates to lower warranty claims
• Margin-stable – Pneumatic tools maintain consistent pricing; not subject to battery/electric component cost fluctuations
• Customer retention – Once installed, customers repurchase replacement components and accessories
• Cross-sell opportunity – Pair with air compressors, hose kits, and fluid filtration systems

Why This Pump Stands Out

The 5:1 ratio represents the optimal balance for general-purpose oil transfer in busy shops. Unlike 1:1 models that require excessive air consumption, or 50:1 models that sacrifice speed for pressure, this mid-range pump delivers practical flow rates while maintaining reasonable air-line requirements. The double-action piston design ensures smooth, pulse-free delivery—critical for precision fluid applications like automatic transmissions and hydraulic systems.

The clamping mechanism and differential air motor architecture directly reduce operator downtime through simplified maintenance. Fewer moving parts mean fewer failure points and lower long-term ownership costs for your customers.

Ideal for

• Automotive service shops (oil changes, fluid top-ups, transmission services)
• Fleet maintenance facilities (bulk fluid transfers)
• Heavy equipment service centers (hydraulic and gear oil applications)
• Industrial workshops (equipment maintenance and lubrication)
• Mobile service units (portable, efficient fluid delivery)

For shops with higher-volume demands, consider our 50:1 ratio pneumatic pump for maximum pressure and slower, more controlled delivery.
